LameXP is a graphical user-interface (front-end) for various of audio encoders: It allows you 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 encoder, but supports a wide range of output formats, including MP3, Ogg Vorbis, AAC/MP4, FLAC, AC-3 and Wave Audio. The number of supported input formats is even bigger! Furthermore LameXP does NOT only run on Windows XP, but also on Windows Vista, Windows 7 and many other operating systems.
As all the encoders and decoders used by LameXP 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, e.g. run it from 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 a single step. And, as LameXP is able to process several audio files in parallel, it takes 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 encoders available and by giving the user unrestricted control over all encoding parameters. In addition to that, LameXP provides full support for metadata, including cover art. So when converting your audio files, LameXP will retain existing meta tags. But there also is an easy-to-use editor for adding or modifying metadata. LameXP supports Unicode for both, meta tags and filenames, so there won't be any problems with "foreign" characters. And, thanks to our translators, the user-interface of LameXP is available in multiple languages. Last but not least, LameXP supports a number of post-processing filters, including sample rate conversion, normalization (gain), tone adjustment and downmixing of multi-channel sources.
Platform Support
----------------
**Tier #1:** LameXP is currently being developed on the following platforms:
* Microsoft Windows 8.1, 32-Bit and 64-Bit editions
* Microsoft Windows 7 with Service Pack 1, 32-Bit and 64-Bit editions
*Remarks:* Windows XP has reached "end of life" on April 8th, 2014. This means that Microsoft has stopped all support for Windows XP, i.e. *no* updates or bugfixes are made available to regular Windows XP uses since that date, *not* even security fixes! Thus, all the security vulnerabilities that have been discovered *after* this deadline - and all the security vulnerabilities that will be discovered in the future - are going remain *unfixed* 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 contemporary system.

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.
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, 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. Click the "Show details" button to show details about a file.
*Did you know?* Files can also be added via [Drag & Drop](http://en.wikipedia.org/wiki/Drag_and_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).
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.
Finally, you need to choose your **compression settings**. First, and most important, you must decide for an output *audio format (encoder)*. Depending on your needs and preferences, you can choose between [MP3](http://en.wikipedia.org/wiki/MP3), [Ogg/Vorbis](http://en.wikipedia.org/wiki/Vorbis), [Opus](http://en.wikipedia.org/wiki/Opus_%28audio_format%29), [AAC/MP4](http://en.wikipedia.org/wiki/Advanced_Audio_Coding), [FLAC](https://xiph.org/flac/) and others.
*Note:* If you are uncertain which audio format to choose, then [this article](http://lifehacker.com/5927052/whats-the-difference-between-all-these-audio-formats-and-which-one-should-i-use) by Lifehacker is a good starting point. Also see the [comparison of audio coding formats](http://en.wikipedia.org/wiki/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. The available rate-control modes include VBR (quality-base variable bitrate), ABR (average bitrate) and CBR (constant bitrate). Not all modes are available for all audio formats.
*Note:* If you are uncertain which rate-control mode to chose, the guideline is that VBR mode should be preferred over ABR mode whenever possible. And CBR mode generally should be avoided. See also Wikipedia's article on [variable bitrate](http://en.wikipedia.org/wiki/Variable_bitrate) encoding.
Last but not least, you need to choose the desired target *bitrate* or *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.
*Note:* If you are uncertain which bitrate or quality-level to choose, bare in mind that a higher bitrate (or a better quality level) results in better audio quality, but also produces larger files – and vice versa. "Level 2" or "192 kbps" is a typical choice for MP3.
*Did you know?* You can click on the "Reset" link at any time in order to reset all available settings for all available encoders to their factory defaults.
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.
Before you report any problems that you may have encountered with the LameXP software, please make sure that the problem can be *reproduced* with the **latest** release version of LameXP!
It is *highly recommended* to download LameXP *only* from one of the official mirrors listed above. We assume *no responsibility* for the integrity and trustworthiness of LameXP downloads you may have received from other locations!

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++**](http://en.wikipedia.org/wiki/C%2B%2B) programming language. LameXP v4 uses the [*Qt cross-platform application framework*](http://www.qt.io/) and provides full [*Unicode*](http://en.wikipedia.org/wiki/Unicode) support. Furthermore, LameXP is tightly coupled with the [*MUtilities*](https://github.com/lordmulder/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*](https://www.winehq.org/); a native Linux port of LameXP is planned for a future version.
The source code of the **LameXP** software is managed using the [*Git*](http://git-scm.com/) version control system. The Git repository can be *cloned* from one of the official Git mirrors:

For Windows users, we highly recommend using [*MSYS Git*](http://msysgit.github.com/) in conjunction with the superb [*Tortoise Git*](http://tortoisegit.googlecode.com/) front-end.
Build Prerequisites
-------------------
LameXP is currently being developed and built using the following development tools and libraries:
* [Visual Studio 2013 Update-4](http://www.visualstudio.com/en-us/downloads/download-visual-studio-vs.aspx), running on Windows 7 with Service Pack 1
* [Qt libraries 4.8.6](http://download.qt.io/archive/qt/4.8/) for Windows (pre-compiled Qt libraries for Visual Studio 2013 can be found [**here**](http://sourceforge.net/projects/lamexp/files/Miscellaneous/Qt%20Libraries/))
* Windows Platform SDK v7.1A, included with Visual Studio 2013 or Visual Studio 2012
* The minimum supported *build* platform is Windows 7 (x86 and x64)
* [UPX](http://upx.sourceforge.net/) – the Ultimate Packer for eXecutables
* [Pandoc](http://johnmacfarlane.net/pandoc/) – the Universal Document Converter
* [GnuPG](ftp://ftp.gnupg.org/gcrypt/binary/) – the GNU Privacy Guard v1.4.x
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 2013* with Update-4 (or later) is installed
2. Make sure *Strawberry Perl *for Windows and *Python 2.7* are installed
3. Download and extract the *Qt 4.8.x* source code package (e.g. to ``C:\QtSources\4.8.x``)
4. Edit the file ``mkspecs\win32-msvc2010\qmake.conf`` from your Qt Sources directory as follows:
