LameXP

Audio-Encoder Front-End – Manual

1 Introduction

LameXP is a graphical user-interface (GUI front-end) for various of audio encoders and decoders: It allows you to convert your audio files from one audio format to another one in the most simple way. Despite its name, LameXP is not only a front-end for the LAME MP3 encoder, but supports a wide range of output formats, including MP3, Ogg Vorbis, Opus, AAC/MP4, FLAC, AC-3 and Wave Audio. The number of supported input formats is even bigger! Furthermore LameXP not only runs on Windows XP, but also on Windows 7, 8 and 10 as well as other operating systems. 32-Bit and 64-Bit systems are supported.

Since all the encoders and decoders that are used by the LameXP software are already built-in (with one exception), you do not need to install any additional software, such as "Codecs", "Filters" or "Plug-ins", on your computer. Everything works "out of the box". You can even use LameXP as a "portable" application, i.e. you can run LameXP directly off your USB stick. Moreover, LameXP was designed for batch processing. This means that you can convert a huge number of audio files, e.g. a complete album or even your entire music collection, in just a single step. At the same time, LameXP is able to process several audio files concurrently, so it can take full advantage of modern multi-core processors! However, LameXP is not only optimized for speed, it also provides excellent sound quality by using the most sophisticated audio encoders available.

In addition to that, LameXP provides full support for meta information, including cover artwork. So when converting your audio files with LameXP, any existing meta information will be retained – to the highest possible extent. Of course, there also is an easy-to-use meta-tag editor for adding new meta information or managing the existing meta information. On top of it all, LameXP provides full Unicode support, for meta information as well as file names, thus problems with "intentional" character sets are avoided. Likewise, thanks to our translators, the user-interface of the LameXP software is available in many different languages, including English, German, Spanish and Chinese. Last but not least, LameXP supports a number of post-processing filters, including sample rate conversion, normalization (gain adjustment), tone adjustment as well as down-mixing.

1.1 Platform Support

Tier #1: LameXP is currently being developed on the following platforms:

Tier #2: The following platforms should work too, but aren't tested extensively:

The following legacy platforms are not actively supported any longer:

Remarks: Windows XP has reached "end of life" on April 8th, 2014. This means that Microsoft has stopped all support for Windows XP. Thus no updates or bugfixes are made available to regular Windows XP users since that date, not even security fixes! Thus, all the security vulnerabilities that have been discovered after the deadline – and all the security vulnerabilities that are going to be discovered in the future – will persists forever! Consequently, using Windows XP has become a severe security risk, and the situation is only going to get worse. While LameXP will continue to support Windows XP (note that Service Pack 3 is required!) for the foreseeable future, we highly recommend everybody to update to a less antiquated system now. Windows XP support will be discontinued in a future version, when most users have migrated to a modern system.

1.2 Output Formats (Encoders)

Currently the following output formats (audio encoders) are supported by LameXP:

1.3 Input Formats (Decoders)

Currently the following input formats (audio decoders) are supported by LameXP:

3 Anti-Virus Notes
 
Occasionally, it may happen that your anti-virus software mistakenly detects malware (virus, trojan horse, worm, etc.) while you are trying to run the LameXP application or the LameXP setup program. This is called a false positive and the file actually is not malware. Instead, this is an error (bug) in your particular anti-virus software! In case that you encounter this kind problem, we highly recommend using VirusTotal.com, Virscan.org or a similar web-service to check the file in question with multiple anti-virus engines. Unless the vast majority of the anti-virus engines detect malware, it can be assumed that the file is really harmless. However, please take care with heuristic scan results, such as "suspicious", "generic" or "packed". Those results are not malware detections – they are highly speculative and (almost certainly) can be ignored safely!
 
Defective anti-virus software is an ongoing annoyance! For example, anti-virus programs tend to suspect installers (or uninstallers) created with NSIS – which includes the LameXP setup program. But, of course, installers created with NSIS are perfectly legitimate. Thus, if your anti-virus program complains about the LameXP setup program, please ignore the nonsensical warning! Furthermore, it seems that some anti-virus programs accuse all "packed" executables of being malware. Nonetheless, using so-called "executable packers", e.g. UPX, is perfectly legitimate. Executable packers are commonly used by legitimate software, including numerous OpenSource projects – and so does LameXP. Thus, if your anti-virus program complains about the LameXP program file, because it has been "packed" by UPX, please ignore the nonsensical warning!
 
Last but not least: Always keep in mind that LameXP is free software, which means that the source codes of LameXP are freely available. Everybody can easily see that there is no malware of any kind included in the LameXP source code! If you do not trust the provided binaries of LameXP, you may build your own binary directly from the LameXP source codes…
 
3.1 Reporting False Positives
 
An important fact to consider is, that, for the developer of a legitimate application, it is impossible to know why a specific anti-virus software may be misinterpreting his or her application as malware. That is because anti-virus programs generally are proprietary (ClosedSource) software – anti-virus companies don not publish their source codes or reveal their algorithms. Moreover, a zillion of different anti-virus programs exist nowadays. For these reasons, the application developer can not know what is going on "behind the scenes" in a particular anti-virus software. Consequently, any assumptions on the reasons that are causing the false positive would be nothing but pure speculation! Even worse, anti-virus software is updated frequently, so the reasons why the anti-virus software is misinterpreting the application as malware may change constantly!
 
At this point, it should be clear that implementing workarounds for defective anti-virus software is not a viable option for application developers. Instead, since the false positive is an error (bug) in the particular anti-virus software, it can be fixed only by the developer of the anti-virus software. Therefore, it is important that you, the (paying) customer of the anti-virus company, contact the support team of the anti-virus company and report the problem to them! Most anti-virus companies provide ways to report false positives in a standardized way, e.g. by means of a webform. However, it is not possible to list them all here. So please refer to the anti-virus developer's web-site. Also, when reporting false positives, please be self-confident! As a paying customer, you can demand that false positives are fixed promptly. Otherwise, get your money back!
 
3.2 Performance Issues
 
During the startup procedure, the LameXP software has to perform a number of file-system operations. This can take a few moments. However, the startup procedure should never take longer than approximately 5 seconds. Even on our test system – Windows 7 running on an ancient Intel Core2 processor with 4 GB of RAM – the startup procedure takes only about 1.5 seconds. And that is with the "real-time protection" of Microsoft Security Essentials (MSE) enabled! If we disable the MSE "real-time protection" feature, the startup procedure takes less than 0.5 seconds. Unfortunately, it has been brought to our attention, that some other anti-virus products may slow down the startup procedure significantly! Startup delays of up to 20 seconds have been reported by users, which corresponds to a slow down factor of 40× – caused by the anti-virus software!
 
Consequently, if you think that LameXP is starting up "slow" on your machine, we recommend to temporarily disable or uninstall your current anti-virus software. If your anti-virus software has a so-called "real-time protection" or "guard" feature, please be sure to deactivate that feature too! As soon as the anti-virus software has been neutralized and no longer affects legitimate applications, please try launching the LameXP software again. If it turns out that the startup procedure of LameXP has become significantly faster when the anti-virus software is not interfering, then you know one thing for sure: It is the anti-virus software that was causing the slow down! Please recognize that we can not fix this kind of problems. Instead, since the problem is actually a defect of the anti-virus software, please report the problem to the developer of the anti-virus software!
 
Another way of detecting performance issues that are caused by sloppy anti-virus software is monitoring the CPU usage in Task Manager (or Process Explorer) while LameXP is starting up. Please make sure that you are not looking at the "overall" CPU usage, but at the CPU usage caused by the individual processes, and that "show processes from all users" is enabled. Then you will probably notice that LameXP.exe is sitting "idle", more or less, while some service process belonging to the anti-virus software is "hogging" the CPU. The anti-virus software is hindering LameXP startup! A typical example looks like this:
 
 
Please report performance issues to the anti-virus software's developer. Also, when reporting performance issues, please be self-confident! As a paying customer, you can demand that such bugs are fixed promptly. Otherwise, get your money back!
 
3.3 Anti-Virus Conclusions
 
The code of conduct regarding problems and annoyances related to so-called "anti-virus" software:
  
4 Install Instructions
 
This chapter explains how to install the LameXP software on your computer. If LameXP has already been installed on your computer, you may skip this chapter.
 
4.1 Install the LameXP Software
 
Distribution packages of the LameXP software is provided in two different flavours: a self-running setup program and a ZIP package. For regular users, using the setup program is highly recommended!
 
4.1.1 Setup Program
 
In order to start the installation process, simply double-click on the downloaded LameXP setup program, e.g. LameXP.yyyy-mm-dd.Release-Static.Build-xxxx.exe.
 
Shortly after launching the setup program, an UAC (User Access Control) dialogue may appear. This is a standard Windows security feature, so don't worry! You have to choose "Yes", if you wish to continue the installation process.
 
Note: If you wonder why Windows suggests that the LameXP setup program originates from an "unknown publisher", despite the fact that it was downloaded from the official web-site, then please the explanation here!
 
 
Now simply follow the instructions of the setup wizard, which will guide you through the installation process…
 
Note: Please do not change the "Destionation Folder", unless you know exactly what you are doing. The "Destionation Folder" cannot be changed, when upgrading an existing LameXP installation.
 
 
Congratulation, LameXP has been installed successfully on your computer!
 
Note: If you keep the "Run LameXP …" option enabled and click on the "Finish" button, the LameXP software will be launched immediately.
 
 
4.1.2 ZIP Package
 
If you decided for the ZIP package, you need to open the downloaded ZIP file, e.g. LameXP.yyyy-mm-dd.Release-Static.Build-xxxx.zip, in your favourite file archive software (we recommend using 7-Zip or WinRAR).
 
 
This step may be slightly different, depending on what file archive software (e.g. 7-Zip or WinRAR) you are using. Select all files in the LameXP ZIP archive and extract them to a new/empty directory of your choice.
 
Note: It is very important that you have write-access to the chosen destination directory. So make sure that you choose a directory where the required access rights are granted!
 
 
Congratulation, LameXP has been installed successfully on your computer! Now double-click on the LameXP.exe program file in order to launch the application!
 
 
4.2 Portable Mode
 
First of all, it is important to note that there is no such thing as a separate "portable version" or "portable edition" of the LameXP software. Instead, all versions of the LameXP software always are "portable" – in the sense that the LameXP software is fully self-contained and thus no additional dependencies (libraries, frameworks, codecs or whatsoever) need to be installed on the computer separately. Or, in other words, the LameXP software is designed to work "out of the box". And this applies regardless of whether you choose the setup program or the ZIP package!
 
Nonetheless, the LameXP software supports a so-called "portable mode", which can be enabled or disabled at any time. By default, i.e. when the "portable mode" is not enabled, LameXP will store all of its configuration files in the current user's %APPDATA% directory. This is the correct way of storing user-specific configuration files on a modern multi-user operating system. Some users, however, may wish to use LameXP as a portable application. For example, they may wish to run the LameXP software directly off an USB flash drive – and do that on many different machines. In this particular situation, storing the configuration files in the same location where the LameXP program file resides (e.g. on the USB flash drive), instead of the local %APPDATA% directory, may come in handy! And that is exactly what LameXP does when the "portable mode" is enabled.
 
4.2.1 Enable the Portable Mode
 
If you fully understand what the consequences of the "portable mode" are and still want to enable this mode, then simply rename the LameXP program file form LameXP.exe to LameXP-Portable.exe. You must exit LameXP, before you can rename the program file!
 
Note: By default, the LameXP installation directory is either C:\Program Files (x86)\MuldeR\LameXP or C:\Program Files\MuldeR\LameXP. However, this can be changed by the user during the setup process.
 
 
Portable Mode Warning
 
While the "portable mode" is in effect, it is the user's responsibility to ensure that LameXP will be provided with the proper access rights to save/load its configuration files to/from the LameXP program directory!
 
Note: The directories C:\Program Files (x86) and C:\Program Files usually are "protected" by the operating system, so LameXP probably will not be able to write into these directories.
 
4.2.2 Disable the Portable Mode
 
If you wish to disable the "portable mode" again, then all you need to do is renaming the LameXP program file form LameXP-Portable.exe back to LameXP.exe. You must exit LameXP, before you can rename the program file!
 
Note: After the "portable mode" has been disabled, any configurations files that may have been created in the LameXP installation directory will no longer be recognized. Therefore, you can delete these files safely…
 
4.3 Install the AAC Encoder
 
For legal reasons, the AAC (Advanced Audio Coding) encoder can not be included in the official LameXP distribution packages. Therefore, you need to download and install the AAC encoder manually. Don't worry, it's easy!
 
LameXP can use the Nero Digital AAC encoder as well as the QAAC (Apple iTunes/QuickTime) encoder. This chapter describes how to set up one of these AAC encoders for use with the LameXP software.
 
Note: If you are uncertain which AAC encoder to choose, please be aware that the QAAC encoder may produce slightly better sound quality, according to listening tests, while the Nero Digital encoder is less hassle to install.
 
4.3.1 Nero Digital AAC Encoder
 
First of all, you need to download the Nero AAC encoder from one of the following mirror sites:
  
Note: Although the ZIP file is sometimes called NeroAACCodec-1.5.1.zip, it may actually contains version 1.5.4.0 of the Nero AAC encoder software. Check the included changelog.txt to verify this!
 
 
Now open the downloaded ZIP file with your favourite file archive software (we recommend using 7-Zip or WinRAR) and navigate to the "win32" sub-directory.
 
 
Finally, extract all the three files neroAacDec.exe, neroAacEnc.exe and neroAacTag.exe into the LameXP installation directory. That is the directory where your LameXP executable file, i.e. the LameXP.exe, is located.
 
Note: By default, the LameXP installation directory is either C:\Program Files (x86)\MuldeR\LameXP or C:\Program Files\MuldeR\LameXP. However, this can be changed by the user during the setup process.
 
 
Once the required Nero AAC files have been put into the proper place, simply restart LameXP in order to enable the AAC encoding support!
 
4.3.2 QAAC (Apple AAC) Encoder
 
Getting the Apple/QuickTime AAC encoder ready involves two separate steps: In the first place we will install the QAAC encoder, and in the second place we will install the Apple AAC encoder libraries.
 
Install QAAC Encoder
 
First of all, you need to download the QAAC application, which provides a CLI font-end to the Apple/QuickTime AAC encoder. QAAC is provided as an Add-in for LameXP and is available from the following locations:
  
Now open the downloaded ZIP file, e.g. LameXP.qaac-addin.yyyy-mm-dd.zip, with your favourite file archive software (we recommend using 7-Zip or WinRAR) to find the required QAAC program files.
 
Note: The LameXP software generally expects the latest version of the QAAC add-in; and the QAAC add-in is designed to work with the latest version of the LameXP software. Make sure your files are up-to-date!
 
 
Please extract all the three files, the program qaac.exe plus its companion DLLs libsoxr.dll and libsoxconvolver.dll, into the LameXP installation directory. That is the directory where your LameXP executable file, i.e. the LameXP.exe, is located.
 
Note: By default, the LameXP installation directory is either C:\Program Files (x86)\MuldeR\LameXP or C:\Program Files\MuldeR\LameXP. However, this can be changed by the user during the setup process.
 
 
Install Apple AAC Encoder Libraries
 
Next, the actual Apple/QuickTime AAC encoder libraries, which are part of the so-called "Apple Application Support" package, need to be installed on your computer. QAAC can not work without these libraries!
 
The required "Apple Application Support" package is included, for example, in the official setup packages of QuickTime or iTunes for Windows, which can be obtained from the Apple web-site free of charge:
  
Since you usually do not want to install the complete QuickTime (or iTunes) software on your computer, please only download the QuickTime (or iTunes) setup package, but do not actually run the installer!
 
Instead, open the QuickTimer setup program, i.e. QuickTimeInstaller.exe, with your favourite file archive software (we recommend using 7-Zip or WinRAR) and extract the required AppleApplicationSupport.msi package.
 
 
After the "Apple Application Support" setup package has been extracted, you can launch it by double-clicking on the AppleApplicationSupport.msi file. Then simply follow the installer's instructions!
 
Note: If you do not want to install the "Apple Application Support" software at all, there is an alternative method, that will extract only the required DLL files from the MSI package. See here for details…
 
 
Once the QAAC encoder as well as the Apple AAC encoder libraries ("Apple Application Support") have been installed properly, simply restart LameXP in order to enable the AAC encoding support!
 
Note: You may run qaac.exe --check from the command prompt to ensure that QAAC has been set up correctly. Expected output is qaac 2.xx, CoreAudioToolbox x.x.x.x.
 
5 Tutorial (Step-by-Step Guide)
 
This tutorial will teach you, step by step, how to convert your audio files using the LameXP software. The tutorial assumes that LameXP is already installed on your computer.
 
5.1 Source Files
 
First of all, you need to add all source files that you want to convert. So switch to the "Source Files" tab, just in case that tab is not active already, and then click the "Add File(s)" button.
 
 
This will bring up a standard file selection dialogue. Now simply select the files that you want to add and click the "Open" button. You can repeat this step multiple times, e.g. to add files from different directories.
 
 
All files you have added, so far, will show up in the list. You can click the "Remove" button to remove a single file from the list or "Clear" to remove them all. You can also click the "Show details" button to show details about the selected file.
 
 
If you want to add an entire directory, you can select "Open Folder" from the "File" menu, which will bring up a directory selection dialogue. "Open Folder Recursively" works in a similar way, but also includes all sub-directories.
 
 
Did you know? Files can also be added via Drag & Drop. Just grab the files that you want to add in your Explorer window and drop them onto the LameXP main window (or onto the LameXP "dropbox" widget).
 
5.2 Output Directory
 
Next, you need to choose the output directory, i.e. the directory where the converted files will be saved. Switch to the "Output Directory" tab and choose the desired output directory from the directory tree view.
 
Note: There are several quick navigation buttons below, which will allow you to jump quickly to your personal "Home" folder, "Desktop" folder and "Music" folder, respectively.
 
 
Sometimes you may wish to store the converted files in a new (sub-)folder. In this case, simply click the "Make New Folder" button, enter the desired folder name and hit the "OK" button.
 
 
The new folder is going to be created inside the current directory and will be selected automatically. You can repeat this step multiple times in order to created nested sub-folders.
 
 
Did you know? If you enable the "Save output files in the same directory where the input file is located" option, each output file will be saved to the same location where the corresponding source file resides.
 
5.3 Compression Settings
 
Finally, you need to choose your compression settings. Most important, you must decide for an output format (encoder). Depending on your needs and preferences, you can choose between MP3, Ogg/Vorbis, Opus, AAC/MP4, FLAC and others.
 
Note: If you are uncertain which audio format to choose, then this article by Lifehacker is a good starting point. Also see the comparison of audio coding formats on Wikipedia. If still uncertain, just go with good old MP3 😉
 
 
Once you have decided for an audio format, you need to choose a rate-control mode next. This controls how the bits are allocated for the compressed audio files. The available rate-control modes are CBR, VBR and ABR:
  
Note: If you are uncertain which rate-control mode to chose, the rule of thumb is that VBR mode should be preferred over ABR mode when possible. And CBR mode should be avoided. See also Wikipedia's article on variable bitrate encoding.
 
 
Last but not least, you need to choose the desired target bitrate (kbps) or the desired quality-level. Put simply, this controls the "quality vs. file size" trade-off. You choose a target quality-level in case of VBR mode. And you choose a target (average) bitrate in case of ABR or CBR mode. A higher target bitrate or a higher target quality level results in improved audio quality, but also comes at the cost of larger files. Conversely, a lower target bitrate or a lower target quality level results in smaller files, but also comes at the cost of reduced audio quality. The "optimal" setting highly depends on your personal preferences.
 
Note: If you are uncertain which bitrate or quality-level to choose, "Level 2" (VBR) or "192 kbps" (ABR) is a common choice for MP3. If the size of the resulting file is not a primary concern, you can go with "Level 0" (VBR) or "320 kbps" (ABR) right away.
 
 
Did you know? You can click the "Reset" link in order to reset all compression settings for all encoders to their factory defaults.
 
5.4 File Processing
 
When everything has been set up properly, the time has come to actually start the encoding process. So simply click the "Encode Now" button in order to get going!
 
 
This will bring up the "Processing" dialogue. LameXP will now convert all your audio files on the list. Depending on the number of audio files and depending on the performance of your system, this may take several minutes, so please be patient 😉
 
Note: In order to leverage the power "multi-core" processors and thus massively speed-up the encoding process, LameXP will run multiple encoding jobs in parallel – provided that your system has multiple processor cores and that there are enough encoding jobs left in the queue.
 
 
The "Processing" dialogue is going to turn green, as soon as all encoding jobs have finished successfully. If anything went wrong, e.g. if one of the encoding jobs failed for some reason, it will turn red instead.
 
 
Did you know? You can double-click on a completed (or failed) job in the list, in order to bring up a dialogue with all details about the specific job. This is especially useful, if something went wrong.
 
6 Command-line Usage
 
Additional command-line options may be passed to LameXP when launching the application. You may do so, for example, by typing the complete command-line into the command prompt or by creating a shortcut with the desired command-line options. The basic command-line syntax of LameXP is as follows: Each command-line option has to start with a -- prefix. So if you intend to pass the option called "foo", then you actually need to type --foo. Furthermore, while some command-line options are just flags, i.e. they can either be present or not (but that's it!), there also are command-line options that take an argument. The argument is appended directly to the option name to which it belongs to, but a = sign must to be inserted as a separator. If, for example, you wish to set the command-line option "foo" to an argument value of "bar", then the proper syntax is --foo=bar. Sometimes your argument value may contain whitespaces though, in which case the whole command-line option (name + argument) must be enclosed with double quotes. For example, in order to set the option "foo" to a value of "C:\Some File.bar" (note the space character between "Some" and "File"), the proper syntax is "--foo=C:\Some File.bar". Last but not least, please note that the same command-line option may appear multiple times on the command-line – whether that actually makes any sense depends on the individual option though.

8 Developer Center
 
While LameXP originally was written in Delphi/Pascal, the current version 4 series of the software has been re-written in the C++ programming language. LameXP v4 uses the Qt cross-platform application framework and provides full Unicode support. Furthermore, LameXP is tightly coupled with the MUtilities library, a vast collection of "utility" routines and classes to extend the Qt framework. Build files are currently provided for Microsoft Visual Studio only. Linux support is currently provided via Wine; a native Linux port of LameXP is planned for a future version.
 
8.1 Source Code Access
 
The source code of the LameXP software is managed using the Git version control system. The Git repository can be cloned from one of the official Git mirrors:

Remarks: In case you are new to Git or want to extend your knowledge, have a look at the Pro Git book by Scott Chacon! For Windows users, we highly recommend using MSYS Git in conjunction with the superb Tortoise Git front-end.
 
8.2 Build Prerequisites
 
LameXP is currently being developed and built using the following development tools and libraries:
  
In order to create LameXP release packages, using the included deployment scripts, you need the following additional tools:
  
8.3 Directory Layout
 
In order to build LameXP using the provided project/solution files or the provided deployment script, please make sure you have the following directory layout, where <sources_root> is a new/empty directory:
  
The Qt libraries need to be located at the following location, where the <toolset_version> identifies your compiler version (e.g. v140_xp for VS2015) and the <build_type> identifies the build configuration (Shared, Static or Debug):
  
8.4 Environment variables
 
In order to build LameXP using the provided project/solution files or the provided deployment script, make sure the following environment variables are configured on your system:
  
8.5 Using the deployment script
 
In order to create LameXP release packages, using the included deployment scripts, copy the configuration template file buildenv.template.txt, located at <sources_root>\LameXP_Qt\etc\Deployment, to the file buildenv.txt in the same directory. Now edit your buildenv.txt and adjust all the path variables as needed. All paths must be set up correctly, otherwise the build process is going to fail! Once everything has been set up, you can run release.bat or release_static.bat in order to create a new release package.
 
8.6 Qt as Static Libraries
 
In order to create a "fully static" build of LameXP, i.e. a build that does not depend on any "external" DLL files (except for the obligatory operating system DLL's that you cannot get around), you'll need to compile Qt as "static" libraries. The official Qt web-site does provide pre-compiled Qt libraries. However, they only provide DLL versions, they do not provide "static" libraries. Consequently, you need to build the required "static" Qt libraries yourself. The following simple instructions should make it easy to build Qt from the sources and as "static" libraries:
 
     
  1. Make sure Visual Studio 2015 with Update-1 (or later) is installed
    2.  
  2. Make sure Strawberry Perl for Windows and Python 2.7 are installed
    3.  
  3. Download and extract the Qt 4.8.x source code package (e.g. to C:\QtSources\4.8.x)
    4.  
  4. Edit the qmake configuration file (e.g. mkspecs\win32-msvc2015\qmake.conf) from your Qt Sources directory as follows:
     
       
    • Edit #1: 
         
      • ⇐ QMAKE_CFLAGS_RELEASE = -O2 -MD
        •  
      • ⇒ QMAKE_CFLAGS_RELEASE = -O2 -MT <more optimization flags here>
        •  
      •  
    • Edit #2: 
         
      • ⇐ QMAKE_CFLAGS_RELEASE_WITH_DEBUGINFO += -O2 -MD -Zi
        •  
      • ⇒ QMAKE_CFLAGS_RELEASE_WITH_DEBUGINFO += -O2 -MT -Zi <more optimization flags here>
        •  
      •  
    5.  
  5. Open a new command window (cmd.exe) – use this very same console for all upcoming steps!
    6.  
  6. Add Strawberry Perl to your PATH (e.g. set PATH=C:\strawberry\perl\bin;%PATH%)
    7.  
  7. Add Python 2.7 to your PATH (e.g. set PATH=C:\python27;%PATH%)
    8.  
  8. Run vcvarsall.bat x86 form your Visual C++ install directory - within the same console!
    9.  
  9. Change the current directory to the Qt Sources path (e.g. C:\QtSources\4.8.x)
    10.  
  10. Run configure.exe -release -static -ltcg -qt-zlib -qt-libpng -qt-libjpeg -qt-libtiff -qt-libmng
    11.  
  11. Now the makefiles should have been generated, so simply enter nmake /B and be patient - voilà!
    12.  
  12. The build process is going to take good amount of time. Once it is done, make sure you got all needed libs:
     
       
    • lib\qtmain.lib
      •  
    • lib\QtCore.lib
      •  
    • lib\QtGui.lib
      •  
    • lib\QtSvg.lib
      •  
    • lib\QtXml.lib
      •  
    • plugins\imageformats\qico.lib
      •  
    • plugins\imageformats\qsvg.lib
      •  
    • plugins\imageformats\qtga.lib
      •  
    13.  
  13. Put all the static *.lib files into the <sources_root>\Prerequisites\Qt4\<toolset_version>\Static\lib directory
    14.  
  14. ImageFormat plugins go to <sources_root>\Prerequisites\Qt4\<toolset_version>\plugins\imageformats
    15.  
  15. Congratulations, you should now be prepared to build the Release_Static configuration of LameXP 😊
    16.  
 
Note: Static libraries only work with the exactly same compiler (version) they were built with!
 
9 F.A.Q. (Frequently Asked Questions)
 
This section tries to answer some of the most frequently asked questions. So if you have a question, please carefully read this section, before you send the question to us via email or before you open a new support ticket 😉
 
9.1 Q: Do I have to pay for using or obtaining LameXP?
 
A: Nope. LameXP is free software. You may use it free of charge and for any purpose, including commercial purposes, according to the terms of the GNU General Public License. The developers of LameXP will never ask you to pay for using the LameXP software. Also, several free download mirrors are provided. However, it was brought to our attention, that there are some third-party web-sites which offer payed downloads of LameXP, or provide LameXP downloads that have been infected with Adware – we do not cooperate with any of these web-sites! Therefore, please do not pay money for using or obtaining the LameXP software; the developers of LameXP will not benefit from this money at all. If anybody tries to make you pay money for using and/or for obtaining the LameXP software, you should not respond to this dubious offer!
 
9.2 Q: Can I redistribute the LameXP software?
 
A: Yes. LameXP is free software. You may modify and/or redistribute it freely, according to the terms of the GNU General Public License. However, be aware that it is strictly forbidden to bundle the LameXP program files and/or the LameXP installation program with any kind of Adware, Spyware or PUP (potentially unwanted program). Usually, no additional permission is needed to redistribute LameXP. If, however, you wish to redistribute the LameXP software in a way that does not comply with the license terms, then a written permission from the author (copyright holder) is absolutely necessary!
 
9.3 Q: How can I donate to the authors of LameXP?
 
A: LameXP is a non-profit project. The authors of the LameXP software currently do not accept any donations, in terms of money. If you wish to support the LameXP project, then you may do so by contributing translations, by improving the LameXP program code or by providing web-servers. Please feel free to contact us at any time, if you want to help!
 
9.4 Q: Why is this software called LameXP?
 
A: Originally, the LameXP software was created as a very simple GUI front-end to the LAME MP3 command-line encoder. The original version of this software, released some time in 2004, did not support any encoders except for LAME, it did not support any input formats except for Wave Audio, it did not support any audio filters, it did not support multi-threading, it did not support Unicode file names and it did not handle meta information. Because the software was a front-end to LAME, and because, back at that time, Windows XP was the most popular Windows version (by far), we decided to call the software "LAME front-end for Windows XP" – or, in short, LameXP. Anyway, more and more features have been added to the LameXP software over the years. Also, the software has been re-written from the scratch two times. Nonetheless, the original name of the software has remained. Now, a whole lot of people know the software by this name, so it is unlikely to ever change.
 
9.5 Q: Why are the LameXP binaries not digitally signed?
 
A: They are signed! The official LameXP binaries are digitally signed by PGP signatures, created using the GnuPG software. However, the LameXP binaries are not signed in a way that the Microsoft Windows operating system recognizes. Please note that Microsoft Windows does not currently recognize PGP (GnuPG) signatures. For this reason, Microsoft Windows may show a warning message when trying to launch or install the LameXP software. Microsoft Windows will also complain that the LameXP program files originate from an "unknown publisher", as it can't understand the PGP signature.
 
So why are the LameXP binaries not signed in the way Microsoft Windows recognizes? This is because Microsoft Windows uses a hierarchical trust model: Windows trusts into a number of Certificate Authorities (CA), which are built into the operating system. These CA's can issue signing certificates, e.g., to software companies. The software company can then use its signing certificate to sign their binaries. Finally, Windows will verify the signature by using the corresponding signing certificate. And the signing certificate is verified using the built-in CA certificate. However, there are problems: First of all, CA's do not issue software signing certificates for free. Also these certificates are only valid for a limited period of time. LameXP is a non-profit project and therefore we can not afford buying new certificates in regular intervals! Secondly, and even more important, the whole system depends on the trustworthiness of a few root CA's. But, as we all (should) know by now, the CA's can be forced to create "bogus" certificates, e.g. on the request of intelligence services or other governmental organizations.
 
PGP, on the other hand, is based on the "web of trust" concept. This means that all participants sign each others' keys – after the keys have been verified. There are no "almighty" authorities! If you want to verify the LameXP signatures yourself, then you may do so by using the Gpg4win software package, an easy-to-use distribution of the GnuPG software for Microsoft Windows. Of course you will also require the public key of the LameXP developers! The finperprint of our PGP signing key is DFAD4340D83D4020435D78BB2B5913365F57E03F and the corresponding public key block is provided in the following. If you are not familiar with the GnuPG software yet, please have a look at the Gpg4win compendium or the GnuPG manual.
 
MuldeR's signature key:
 
pub   rsa4096 2015-08-23 [expires: 2025-08-20]
+Other components contained in the bundle MUST be opt-in, NOT opt-out.
 
3 Anti-Virus Notes
 
Occasionally, it may happen that your anti-virus software mistakenly detects malware (virus, trojan horse, worm, etc.) while you are trying to run the LameXP application or the LameXP setup program. This is called a false positive and the file actually is not malware. Instead, this is an error (bug) in your particular anti-virus software! In case that you encounter this kind problem, we highly recommend using VirusTotal.com, Virscan.org or a similar web-service to check the file in question with multiple anti-virus engines. Unless the vast majority of the anti-virus engines detect malware, it can be assumed that the file is really harmless. However, please take care with heuristic scan results, such as "suspicious", "generic" or "packed". Those results are not malware detections – they are highly speculative and (almost certainly) can be ignored safely!
 
Defective anti-virus software is an ongoing annoyance! For example, anti-virus programs tend to suspect installers (or uninstallers) created with NSIS – which includes the LameXP setup program. But, of course, installers created with NSIS are perfectly legitimate. Thus, if your anti-virus program complains about the LameXP setup program, please ignore the nonsensical warning! Furthermore, it seems that some anti-virus programs accuse all "packed" executables of being malware. Nonetheless, using so-called "executable packers", e.g. UPX, is perfectly legitimate. Executable packers are commonly used by legitimate software, including numerous OpenSource projects – and so does LameXP. Thus, if your anti-virus program complains about the LameXP program file, because it has been "packed" by UPX, please ignore the nonsensical warning!
 
Last but not least: Always keep in mind that LameXP is free software, which means that the source codes of LameXP are freely available. Everybody can easily see that there is no malware of any kind included in the LameXP source code! If you do not trust the provided binaries of LameXP, you may build your own binary directly from the LameXP source codes…
 
3.1 Reporting False Positives
 
An important fact to consider is, that, for the developer of a legitimate application, it is impossible to know why a specific anti-virus software may be misinterpreting his or her application as malware. That is because anti-virus programs generally are proprietary (ClosedSource) software – anti-virus companies don not publish their source codes or reveal their algorithms. Moreover, a zillion of different anti-virus programs exist nowadays. For these reasons, the application developer can not know what is going on "behind the scenes" in a particular anti-virus software. Consequently, any assumptions on the reasons that are causing the false positive would be nothing but pure speculation! Even worse, anti-virus software is updated frequently, so the reasons why the anti-virus software is misinterpreting the application as malware may change constantly!
 
At this point, it should be clear that implementing workarounds for defective anti-virus software is not a viable option for application developers. Instead, since the false positive is an error (bug) in the particular anti-virus software, it can be fixed only by the developer of the anti-virus software. Therefore, it is important that you, the (paying) customer of the anti-virus company, contact the support team of the anti-virus company and report the problem to them! Most anti-virus companies provide ways to report false positives in a standardized way, e.g. by means of a webform. However, it is not possible to list them all here. So please refer to the anti-virus developer's web-site. Also, when reporting false positives, please be self-confident! As a paying customer, you can demand that false positives are fixed promptly. Otherwise, get your money back!
 
3.2 Performance Issues
 
During the startup procedure, the LameXP software has to perform a number of file-system operations. This can take a few moments. However, the startup procedure should never take longer than approximately 5 seconds. Even on our test system – Windows 7 running on an ancient Intel Core2 processor with 4 GB of RAM – the startup procedure takes only about 1.5 seconds. And that is with the "real-time protection" of Microsoft Security Essentials (MSE) enabled! If we disable the MSE "real-time protection" feature, the startup procedure takes less than 0.5 seconds. Unfortunately, it has been brought to our attention, that some other anti-virus products may slow down the startup procedure significantly! Startup delays of up to 20 seconds have been reported by users, which corresponds to a slow down factor of 40× – caused by the anti-virus software!
 
Consequently, if you think that LameXP is starting up "slow" on your machine, we recommend to temporarily disable or uninstall your current anti-virus software. If your anti-virus software has a so-called "real-time protection" or "guard" feature, please be sure to deactivate that feature too! As soon as the anti-virus software has been neutralized and no longer affects legitimate applications, please try launching the LameXP software again. If it turns out that the startup procedure of LameXP has become significantly faster when the anti-virus software is not interfering, then you know one thing for sure: It is the anti-virus software that was causing the slow down! Please recognize that we can not fix this kind of problems. Instead, since the problem is actually a defect of the anti-virus software, please report the problem to the developer of the anti-virus software!
 
Another way of detecting performance issues that are caused by sloppy anti-virus software is monitoring the CPU usage in Task Manager (or Process Explorer) while LameXP is starting up. Please make sure that you are not looking at the "overall" CPU usage, but at the CPU usage caused by the individual processes, and that "show processes from all users" is enabled. Then you will probably notice that LameXP.exe is sitting "idle", more or less, while some service process belonging to the anti-virus software is "hogging" the CPU. The anti-virus software is hindering LameXP startup! A typical example looks like this:
 
 
Please report performance issues to the anti-virus software's developer. Also, when reporting performance issues, please be self-confident! As a paying customer, you can demand that such bugs are fixed promptly. Otherwise, get your money back!

4 Install Instructions
 
This chapter explains how to install the LameXP software on your computer. If LameXP has already been installed on your computer, you may skip this chapter.
 
4.1 Install the LameXP Software
 
Distribution packages of the LameXP software is provided in two different flavours: a self-running setup program and a ZIP package. For regular users, using the setup program is highly recommended!
 
4.1.1 Setup Program
 
In order to start the installation process, simply double-click on the downloaded LameXP setup program, e.g. LameXP.yyyy-mm-dd.Release-Static.Build-xxxx.exe.
 
Shortly after launching the setup program, an UAC (User Access Control) dialogue may appear. This is a standard Windows security feature, so don't worry! You have to choose "Yes", if you wish to continue the installation process.
 
Note: If you wonder why Windows suggests that the LameXP setup program originates from an "unknown publisher", despite the fact that it was downloaded from the official web-site, then please the explanation here!
 
 
Now simply follow the instructions of the setup wizard, which will guide you through the installation process…
 
Note: Please do not change the "Destionation Folder", unless you know exactly what you are doing. The "Destionation Folder" cannot be changed, when upgrading an existing LameXP installation.
 
 
Congratulation, LameXP has been installed successfully on your computer!
 
Note: If you keep the "Run LameXP …" option enabled and click on the "Finish" button, the LameXP software will be launched immediately.
 
 
4.1.2 ZIP Package
 
If you decided for the ZIP package, you need to open the downloaded ZIP file, e.g. LameXP.yyyy-mm-dd.Release-Static.Build-xxxx.zip, in your favourite file archive software (we recommend using 7-Zip or WinRAR).
 
 
This step may be slightly different, depending on what file archive software (e.g. 7-Zip or WinRAR) you are using. Select all files in the LameXP ZIP archive and extract them to a new/empty directory of your choice.
 
Note: It is very important that you have write-access to the chosen destination directory. So make sure that you choose a directory where the required access rights are granted!
 
 
Congratulation, LameXP has been installed successfully on your computer! Now double-click on the LameXP.exe program file in order to launch the application!
 
 
4.2 Portable Mode
 
First of all, it is important to note that there is no such thing as a separate "portable version" or "portable edition" of the LameXP software. Instead, all versions of the LameXP software always are "portable" – in the sense that the LameXP software is fully self-contained and thus no additional dependencies (libraries, frameworks, codecs or whatsoever) need to be installed on the computer separately. Or, in other words, the LameXP software is designed to work "out of the box". And this applies regardless of whether you choose the setup program or the ZIP package!
 
Nonetheless, the LameXP software supports a so-called "portable mode", which can be enabled or disabled at any time. By default, i.e. when the "portable mode" is not enabled, LameXP will store all of its configuration files in the current user's %APPDATA% directory. This is the correct way of storing user-specific configuration files on a modern multi-user operating system. Some users, however, may wish to use LameXP as a portable application. For example, they may wish to run the LameXP software directly off an USB flash drive – and do that on many different machines. In this particular situation, storing the configuration files in the same location where the LameXP program file resides (e.g. on the USB flash drive), instead of the local %APPDATA% directory, may come in handy! And that is exactly what LameXP does when the "portable mode" is enabled.
 
4.2.1 Enable the Portable Mode
 
If you fully understand what the consequences of the "portable mode" are and still want to enable this mode, then simply rename the LameXP program file form LameXP.exe to LameXP-Portable.exe. You must exit LameXP, before you can rename the program file!
 
Note: By default, the LameXP installation directory is either C:\Program Files (x86)\MuldeR\LameXP or C:\Program Files\MuldeR\LameXP. However, this can be changed by the user during the setup process.
 
 
Portable Mode Warning
 
While the "portable mode" is in effect, it is the user's responsibility to ensure that LameXP will be provided with the proper access rights to save/load its configuration files to/from the LameXP program directory!
 
Note: The directories C:\Program Files (x86) and C:\Program Files usually are "protected" by the operating system, so LameXP probably will not be able to write into these directories.
 
4.2.2 Disable the Portable Mode
 
If you wish to disable the "portable mode" again, then all you need to do is renaming the LameXP program file form LameXP-Portable.exe back to LameXP.exe. You must exit LameXP, before you can rename the program file!
 
Note: After the "portable mode" has been disabled, any configurations files that may have been created in the LameXP installation directory will no longer be recognized. Therefore, you can delete these files safely…
 
4.3 Install the AAC Encoder
 
For legal reasons, the AAC (Advanced Audio Coding) encoder can not be included in the official LameXP distribution packages. Therefore, you need to download and install the AAC encoder manually. Don't worry, it's easy!
 
LameXP can use the Nero Digital AAC encoder as well as the QAAC (Apple iTunes/QuickTime) encoder. This chapter describes how to set up one of these AAC encoders for use with the LameXP software.
 
Note: If you are uncertain which AAC encoder to choose, please be aware that the QAAC encoder may produce better sound quality, according to listening tests, while the Nero Digital encoder is less hassle to install.
 
4.3.1 QAAC (Apple AAC) Encoder
 
Setting up the Apple/QuickTime AAC encoder involves two separate steps: In the first step we will install the QAAC application, and in the second step we will add the required Apple AAC encoder libraries.
 
Install QAAC Encoder
 
First of all, you need to download the QAAC application, which provides a CLI font-end to the Apple/QuickTime AAC encoder. QAAC is provided as an add-in for LameXP and is available from the following download locations:
  
Now open the downloaded ZIP file, e.g. LameXP.qaac-addin.yyyy-mm-dd.zip, with your favourite file archiver utility (we recommend using 7-Zip or WinRAR) to find the required QAAC program files.
 
Note: The LameXP software generally expects the latest version of the QAAC add-in; and the QAAC add-in is designed to work with the latest version of the LameXP software. Make sure your files are up-to-date!
 
 
Please extract the program file qaac.exe as well as the DLLs files libsoxr.dll and libsoxconvolver.dll into the LameXP installation directory. That is the directory where your LameXP executable file, i.e. the LameXP.exe, is located.
 
Note: By default, the LameXP installation directory is either C:\Program Files (x86)\MuldeR\LameXP or C:\Program Files\MuldeR\LameXP. However, this can be changed by the user during the setup process.
 
 
Install Apple AAC Encoder Libraries
 
Next, the actual Apple/QuickTime AAC encoder libraries, which are part of the so-called "Apple Application Support" package, need to be installed on your computer. QAAC can not work without these libraries!
 
The required "Apple Application Support" package is included, for example, in the official setup packages of QuickTime or iTunes for Windows, which can be obtained from the Apple web-site free of charge:
  
Since you usually do not want to install the complete QuickTime (or iTunes) software on your computer, please only download the QuickTime (or iTunes) setup package, but do not actually run the installer!
 
Instead, open the QuickTimer setup program, i.e. QuickTimeInstaller.exe, with your favourite file archive software (we recommend using 7-Zip or WinRAR) and extract the required AppleApplicationSupport.msi package.
 
 
After the "Apple Application Support" setup package has been extracted, you can launch it by double-clicking on the AppleApplicationSupport.msi file. Then simply follow the installer's instructions!
 
Note: If you do not want to install the "Apple Application Support" software at all, there is an alternative method, that will extract only the required DLL files from the MSI package. See here for details…
 
 
Once the QAAC encoder as well as the Apple AAC encoder libraries ("Apple Application Support") have been installed properly, simply restart LameXP in order to enable the AAC encoding support!
 
Note: You may run qaac.exe --check from the command prompt to ensure that QAAC has been set up correctly. Expected output is qaac 2.xx, CoreAudioToolbox x.x.x.x.
 
4.3.2 Nero Digital AAC Encoder
 
First of all, you need to download the Nero AAC Codec (Version 1.5.4) as a ZIP archive from one of the following mirror sites, because the original Nero AAC product web-site no longer seems to be functional:
  
 
Now open the downloaded ZIP file NeroAACCodec-1.5.4.zip with your favourite file archiver utility (we recommend using 7-Zip or WinRAR) and then navigate to the "win32" sub-directory.
 
 
Finally, extract all the three files neroAacDec.exe, neroAacEnc.exe and neroAacTag.exe into the LameXP installation directory. That is the directory where your LameXP executable file, i.e. the LameXP.exe, is located.
 
Note: By default, the LameXP installation directory is either C:\Program Files (x86)\MuldeR\LameXP or C:\Program Files\MuldeR\LameXP. However, this can be changed by the user during the setup process.
 
 
Once the required Nero AAC files have been put into the proper place, simply restart LameXP in order to enable the AAC encoding support!
 
5 Tutorial (Step-by-Step Guide)
 
This tutorial will teach you, step by step, how to convert your audio files using the LameXP software. The tutorial assumes that LameXP is already installed on your computer.
 
5.1 Source Files
 
First of all, you need to add all source files that you want to convert. So switch to the "Source Files" tab, just in case that tab is not active already, and then click the "Add File(s)" button.
 
 
This will bring up a standard file selection dialogue. Now simply select the files that you want to add and click the "Open" button. You can repeat this step multiple times, e.g. to add files from different directories.
 
 
All files you have added, so far, will show up in the list. You can click the "Remove" button to remove a single file from the list or "Clear" to remove them all. You can also click the "Show details" button to show details about the selected file.
 
 
If you want to add an entire directory, you can select "Open Folder" from the "File" menu, which will bring up a directory selection dialogue. "Open Folder Recursively" works in a similar way, but also includes all sub-directories.
 
 
Did you know? Files can also be added via Drag & Drop. Just grab the files that you want to add in your Explorer window and drop them onto the LameXP main window (or onto the LameXP "dropbox" widget).
 
5.2 Output Directory
 
Next, you need to choose the output directory, i.e. the directory where the converted files will be saved. Switch to the "Output Directory" tab and choose the desired output directory from the directory tree view.
 
Note: There are several quick navigation buttons below, which will allow you to jump quickly to your personal "Home" folder, "Desktop" folder and "Music" folder, respectively.
 
 
Sometimes you may wish to store the converted files in a new (sub-)folder. In this case, simply click the "Make New Folder" button, enter the desired folder name and hit the "OK" button.
 
 
The new folder is going to be created inside the current directory and will be selected automatically. You can repeat this step multiple times in order to created nested sub-folders.
 
 
Did you know? If you enable the "Save output files in the same directory where the input file is located" option, each output file will be saved to the same location where the corresponding source file resides.
 
5.3 Compression Settings
 
Finally, you need to choose your compression settings. Most important, you must decide for an output format (encoder). Depending on your needs and preferences, you can choose between MP3, Ogg/Vorbis, Opus, AAC/MP4, FLAC and others.
 
Note: If you are uncertain which audio format to choose, then this article by Lifehacker is a good starting point. Also see the comparison of audio coding formats on Wikipedia. If still uncertain, just go with good old MP3 😉
 
 
Once you have decided for an audio format, you need to choose a rate-control mode next. This controls how the bits are allocated for the compressed audio files. The available rate-control modes are CBR, VBR and ABR:
  
Note: If you are uncertain which rate-control mode to chose, the rule of thumb is that VBR mode should be preferred over ABR mode when possible. And CBR mode should be avoided. See also Wikipedia's article on variable bitrate encoding.
 
 
Last but not least, you need to choose the desired target bitrate (kbps) or the desired quality-level. Put simply, this controls the "quality vs. file size" trade-off. You choose a target quality-level in case of VBR mode. And you choose a target (average) bitrate in case of ABR or CBR mode. A higher target bitrate or a higher target quality level results in improved audio quality, but also comes at the cost of larger files. Conversely, a lower target bitrate or a lower target quality level results in smaller files, but also comes at the cost of reduced audio quality. The "optimal" setting highly depends on your personal preferences.
 
Note: If you are uncertain which bitrate or quality-level to choose, "Level 2" (VBR) or "192 kbps" (ABR) is a common choice for MP3. If the size of the resulting file is not a primary concern, you can go with "Level 0" (VBR) or "320 kbps" (ABR) right away.
 
 
Did you know? You can click the "Reset" link in order to reset all compression settings for all encoders to their factory defaults.
 
5.4 File Processing
 
When everything has been set up properly, the time has come to actually start the encoding process. So simply click the "Encode Now" button in order to get going!
 
 
This will bring up the "Processing" dialogue. LameXP will now convert all your audio files on the list. Depending on the number of audio files and depending on the performance of your system, this may take several minutes, so please be patient 😉
 
Note: In order to leverage the power "multi-core" processors and thus massively speed-up the encoding process, LameXP will run multiple encoding jobs in parallel – provided that your system has multiple processor cores and that there are enough encoding jobs left in the queue.
 
 
The "Processing" dialogue is going to turn green, as soon as all encoding jobs have finished successfully. If anything went wrong, e.g. if one of the encoding jobs failed for some reason, it will turn red instead.
 
 
Did you know? You can double-click on a completed (or failed) job in the list, in order to bring up a dialogue with all details about the specific job. This is especially useful, if something went wrong.
 
6 Command-line Usage
 
Additional command-line options may be passed to LameXP when launching the application. You may do so, for example, by typing the complete command-line into the command prompt or by creating a shortcut with the desired command-line options. The basic command-line syntax of LameXP is as follows: Each command-line option has to start with a -- prefix. So if you intend to pass the option called "foo", then you actually need to type --foo. Furthermore, while some command-line options are just flags, i.e. they can either be present or not (but that's it!), there also are command-line options that take an argument. The argument is appended directly to the option name to which it belongs to, but a = sign must to be inserted as a separator. If, for example, you wish to set the command-line option "foo" to an argument value of "bar", then the proper syntax is --foo=bar. Sometimes your argument value may contain whitespaces though, in which case the whole command-line option (name + argument) must be enclosed with double quotes. For example, in order to set the option "foo" to a value of "C:\Some File.bar" (note the space character between "Some" and "File"), the proper syntax is "--foo=C:\Some File.bar". Last but not least, please note that the same command-line option may appear multiple times on the command-line – whether that actually makes any sense depends on the individual option though.

8 Developer Center
 
While LameXP originally was written in Delphi/Pascal, the current version 4 series of the software has been re-written in the C++ programming language. LameXP v4 uses the Qt cross-platform application framework and provides full Unicode support. Furthermore, LameXP is tightly coupled with the MUtilities library, a vast collection of "utility" routines and classes to extend the Qt framework. Build files are currently provided for Microsoft Visual Studio only. Linux support is currently provided via Wine; a native Linux port of LameXP is planned for a future version.
 
8.1 Source Code Access
 
The source code of the LameXP software is managed using the Git version control system. The Git repository can be cloned from one of the official Git mirrors:

Remarks: In case you are new to Git or want to extend your knowledge, have a look at the Pro Git book by Scott Chacon! For Windows users, we highly recommend using MSYS Git in conjunction with the superb Tortoise Git front-end.
 
8.2 Build Prerequisites
 
LameXP is currently being developed and built using the following development tools and libraries:
  
In order to create LameXP release packages, using the included deployment scripts, you need the following additional tools:
  
8.3 Directory Layout
 
In order to build LameXP using the provided project/solution files or the provided deployment script, please make sure you have the following directory layout, where <sources_root> is a new/empty directory:
  
The Qt libraries need to be located at the following location, where the <toolset_version> identifies your compiler version (e.g. v140_xp for VS2015) and the <build_type> identifies the build configuration (Shared, Static or Debug):
  
8.4 Environment variables
 
In order to build LameXP using the provided project/solution files or the provided deployment script, make sure the following environment variables are configured on your system:
  
8.5 Using the deployment script
 
In order to create LameXP release packages, using the included deployment scripts, copy the configuration template file buildenv.template.txt, located at <sources_root>\LameXP_Qt\etc\Deployment, to the file buildenv.txt in the same directory. Now edit your buildenv.txt and adjust all the path variables as needed. All paths must be set up correctly, otherwise the build process is going to fail! Once everything has been set up, you can run release.bat or release_static.bat in order to create a new release package.
 
8.6 Qt as Static Libraries
 
In order to create a "fully static" build of LameXP, i.e. a build that does not depend on any "external" DLL files (except for the obligatory operating system DLL's that you cannot get around), you'll need to compile Qt as "static" libraries. The official Qt web-site does provide pre-compiled Qt libraries. However, they only provide DLL versions, they do not provide "static" libraries. Consequently, you need to build the required "static" Qt libraries yourself. The following simple instructions should make it easy to build Qt from the sources and as "static" libraries:
 
     
  1. Make sure Visual Studio 2015 with Update-1 (or later) is installed
    2.  
  2. Make sure Strawberry Perl for Windows and Python 2.7 are installed
    3.  
  3. Download and extract the Qt 4.8.x source code package (e.g. to C:\QtSources\4.8.x)
    4.  
  4. Edit the qmake configuration file (e.g. mkspecs\win32-msvc2015\qmake.conf) from your Qt Sources directory as follows:
     
       
    • Edit #1: 
         
      • ⇐ QMAKE_CFLAGS_RELEASE = -O2 -MD
        •  
      • ⇒ QMAKE_CFLAGS_RELEASE = -O2 -MT <more optimization flags here>
        •  
      •  
    • Edit #2: 
         
      • ⇐ QMAKE_CFLAGS_RELEASE_WITH_DEBUGINFO += -O2 -MD -Zi
        •  
      • ⇒ QMAKE_CFLAGS_RELEASE_WITH_DEBUGINFO += -O2 -MT -Zi <more optimization flags here>
        •  
      •  
    5.  
  5. Open a new command window (cmd.exe) – use this very same console for all upcoming steps!
    6.  
  6. Add Strawberry Perl to your PATH (e.g. set PATH=C:\strawberry\perl\bin;%PATH%)
    7.  
  7. Add Python 2.7 to your PATH (e.g. set PATH=C:\python27;%PATH%)
    8.  
  8. Run vcvarsall.bat x86 form your Visual C++ install directory - within the same console!
    9.  
  9. Change the current directory to the Qt Sources path (e.g. C:\QtSources\4.8.x)
    10.  
  10. Run configure.exe -release -static -ltcg -qt-zlib -qt-libpng -qt-libjpeg -qt-libtiff -qt-libmng
    11.  
  11. Now the makefiles should have been generated, so simply enter nmake /B and be patient - voilà!
    12.  
  12. The build process is going to take good amount of time. Once it is done, make sure you got all needed libs:
     
       
    • lib\qtmain.lib
      •  
    • lib\QtCore.lib
      •  
    • lib\QtGui.lib
      •  
    • lib\QtSvg.lib
      •  
    • lib\QtXml.lib
      •  
    • plugins\imageformats\qico.lib
      •  
    • plugins\imageformats\qsvg.lib
      •  
    • plugins\imageformats\qtga.lib
      •  
    13.  
  13. Put all the static *.lib files into the <sources_root>\Prerequisites\Qt4\<toolset_version>\Static\lib directory
    14.  
  14. ImageFormat plugins go to <sources_root>\Prerequisites\Qt4\<toolset_version>\plugins\imageformats
    15.  
  15. Congratulations, you should now be prepared to build the Release_Static configuration of LameXP 😊
    16.  
 
Note: Static libraries only work with the exactly same compiler (version) they were built with!
 
9 F.A.Q. (Frequently Asked Questions)
 
This section tries to answer some of the most frequently asked questions. So if you have a question, please carefully read this section, before you send the question to us via email or before you open a new support ticket 😉
 
9.1 Q: Do I have to pay for using or obtaining LameXP?
 
A: Nope. LameXP is free software. You may use it free of charge and for any purpose, including commercial purposes, according to the terms of the GNU General Public License. The developers of LameXP will never ask you to pay for using the LameXP software. Also, several free download mirrors are provided. However, it was brought to our attention, that there are some third-party web-sites which offer payed downloads of LameXP, or provide LameXP downloads that have been infected with Adware – we do not cooperate with any of these web-sites! Therefore, please do not pay money for using or obtaining the LameXP software; the developers of LameXP will not benefit from this money at all. If anybody tries to make you pay money for using and/or for obtaining the LameXP software, you should not respond to this dubious offer!
 
9.2 Q: Can I redistribute the LameXP software?
 
A: Yes. LameXP is free software. You may modify and/or redistribute it freely, according to the terms of the GNU General Public License. However, be aware that it is strictly forbidden to bundle the LameXP program files and/or the LameXP installation program with any kind of Adware, Spyware or PUP (potentially unwanted program). Usually, no additional permission is needed to redistribute LameXP. If, however, you wish to redistribute the LameXP software in a way that does not comply with the license terms, then a written permission from the author (copyright holder) is absolutely necessary!
 
9.3 Q: How can I donate to the authors of LameXP?
 
A: LameXP is a non-profit project. The authors of the LameXP software currently do not accept any donations, in terms of money. If you wish to support the LameXP project, then you may do so by contributing translations, by improving the LameXP program code or by providing web-servers. Please feel free to contact us at any time, if you want to help!
 
9.4 Q: Why is this software called LameXP?
 
A: Originally, the LameXP software was created as a very simple GUI front-end to the LAME MP3 command-line encoder. The original version of this software, released some time in 2004, did not support any encoders except for LAME, it did not support any input formats except for Wave Audio, it did not support any audio filters, it did not support multi-threading, it did not support Unicode file names and it did not handle meta information. Because the software was a front-end to LAME, and because, back at that time, Windows XP was the most popular Windows version (by far), we decided to call the software "LAME front-end for Windows XP" – or, in short, LameXP. Anyway, more and more features have been added to the LameXP software over the years. Also, the software has been re-written from the scratch two times. Nonetheless, the original name of the software has remained. Now, a whole lot of people know the software by this name, so it is unlikely to ever change.
 
9.5 Q: Why are the LameXP binaries not digitally signed?
 
A: They are signed! The official LameXP binaries are digitally signed by PGP signatures, created using the GnuPG software. However, the LameXP binaries are not signed in a way that the Microsoft Windows operating system recognizes. Please note that Microsoft Windows does not currently recognize PGP (GnuPG) signatures. For this reason, Microsoft Windows may show a warning message when trying to launch or install the LameXP software. Microsoft Windows will also complain that the LameXP program files originate from an "unknown publisher", as it can't understand the PGP signature.
 
So why are the LameXP binaries not signed in the way Microsoft Windows recognizes? This is because Microsoft Windows uses a hierarchical trust model: Windows trusts into a number of Certificate Authorities (CA), which are built into the operating system. These CA's can issue signing certificates, e.g., to software companies. The software company can then use its signing certificate to sign their binaries. Finally, Windows will verify the signature by using the corresponding signing certificate. And the signing certificate is verified using the built-in CA certificate. However, there are problems: First of all, CA's do not issue software signing certificates for free. Also these certificates are only valid for a limited period of time. LameXP is a non-profit project and therefore we can not afford buying new certificates in regular intervals! Secondly, and even more important, the whole system depends on the trustworthiness of a few root CA's. But, as we all (should) know by now, the CA's can be forced to create "bogus" certificates, e.g. on the request of intelligence services or other governmental organizations.
 
PGP, on the other hand, is based on the "web of trust" concept. This means that all participants sign each others' keys – after the keys have been verified. There are no "almighty" authorities! If you want to verify the LameXP signatures yourself, then you may do so by using the Gpg4win software package, an easy-to-use distribution of the GnuPG software for Microsoft Windows. Of course you will also require the public key of the LameXP developers! The finperprint of our PGP signing key is DFAD4340D83D4020435D78BB2B5913365F57E03F and the corresponding public key block is provided in the following. If you are not familiar with the GnuPG software yet, please have a look at the Gpg4win compendium or the GnuPG manual.
