<h1 id="introduction"><span class="header-section-number">1</span> Introduction</h1>
|
||
<p>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.</p>
|
||
<p><img src="http://lamexp.sourceforge.net/lamexp.png" alt="LameXP" /></p>
|
||
<p>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.</p>
|
||
<h2 id="platform-support"><span class="header-section-number">1.1</span> Platform Support</h2>
|
||
<p><strong>Tier #1:</strong> LameXP is currently being developed on the following platforms:</p>
|
||
<ul>
|
||
<li>Microsoft Windows 8.1, 32-Bit and 64-Bit editions<br /></li>
|
||
<li>Microsoft Windows 7 with Service Pack 1, 32-Bit and 64-Bit editions<br /></li>
|
||
<li>Microsoft Windows XP with Service Pack 3 <strong>(see remarks)</strong></li>
|
||
</ul>
|
||
<p><strong>Tier #2:</strong> The following platforms should work too, but aren't tested extensively:</p>
|
||
<ul>
|
||
<li>Microsoft Windows 10, 32-Bit and 64-Bit editions<br /></li>
|
||
<li>Microsoft Windows 8.0, 32-Bit and 64-Bit editions<br /></li>
|
||
<li>Microsoft Windows Vista with Service Pack 2, 32-Bit and 64-Bit editions<br /></li>
|
||
<li>Microsoft Windows XP x64 Edition with Service Pack 2<br /></li>
|
||
<li>Microsoft Windows Server 2008 with Service Pack 2<br /></li>
|
||
<li>Microsoft Windows Server 2008 R2 with Service Pack 1<br /></li>
|
||
<li>GNU/Linux (e.g. Ubuntu 12.04), using Wine v1.4+</li>
|
||
</ul>
|
||
<p><strong>Legacy:</strong> The following platforms are NOT actively supported any longer:</p>
|
||
<ul>
|
||
<li>Microsoft Windows 2000<br /></li>
|
||
<li>Microsoft Windows NT 4.0<br /></li>
|
||
<li>Microsoft Windows Millennium Edition<br /></li>
|
||
<li>Microsoft Windows 98<br /></li>
|
||
<li>Microsoft Windows 95</li>
|
||
</ul>
|
||
<p> <br /><em>Remarks:</em> Windows XP has reached "end of life" on April 8th, 2014. This means that Microsoft has stopped all support for Windows XP, i.e. <em>no</em> updates or bugfixes are made available to regular Windows XP uses since that date, <em>not</em> even security fixes! Thus, all the security vulnerabilities that have been discovered <em>after</em> this deadline - and all the security vulnerabilities that will be discovered in the future - are going remain <em>unfixed</em> 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 <em>highly</em> 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.</p>

<h2 id="install-the-lamexp-software"><span class="header-section-number">3.1</span> Install the LameXP Software</h2>
|
||
<p>The LameXP software is provided in two different forms: a self-running <strong>setup program</strong> and a <strong>ZIP package</strong>. For regular users, using the <em>setup program</em> is highly recommended!</p>
|
||
<h3 id="setup-program"><span class="header-section-number">3.1.1</span> Setup Program</h3>
|
||
<p>In order to start the installation process, simply double-click on the LameXP setup program, e.g. <code>LameXP.yyyy-mm-dd.Release-Static.Build-xxxx.exe</code>.</p>
|
||
<p><em>Note:</em> Shortly after launching the setup program, an <a href="http://en.wikipedia.org/wiki/User_Account_Control">UAC</a> (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.</p>
|
||
<p><img src="img/lamexp/setup_1a.png" alt="Figure" /></p>
|
||
<p> <br />Now simply follow the instructions of the setup wizard, which will guide you through the installation process…</p>
|
||
<p><em>Note:</em> Please do <strong>not</strong> change the "Destionation Folder", unless you know exactly what you are doing. The "Destionation Folder" cannot be changed, when <em>upgrading</em> an existing LameXP installation.</p>
|
||
<p><img src="img/lamexp/setup_1b.png" alt="Figure" /></p>
|
||
<p> <br />Congratulation, LameXP has been installed successfully on your computer!</p>
|
||
<p><em>Note:</em> If you keep the "Run LameXP …" option enabled and click on the "Finish" button, the LameXP software will be launched immediately.</p>

<h2 id="install-the-aac-encoder"><span class="header-section-number">3.2</span> Install the AAC Encoder</h2>
|
||
<p>For legal reasons, the AAC (Advanced Audio Coding) encoder can <strong>not</strong> be included in the official LameXP distribution packages. Therefore, you need to download and install the AAC encoder <em>manually</em>.</p>
|
||
<p>LameXP can use the <em>Nero Digital</em> AAC encoder as well as the <em>Apple</em> (iTunes/QucikTime) AAC encoder. This chapter describes how to set up these AAC encoder for use with LameXP.</p>
|
||
<h3 id="nero-digital-aac-encoder"><span class="header-section-number">3.2.1</span> Nero Digital AAC Encoder</h3>
|
||
<p>First of all, you need to download the Nero AAC encoder from the official Nero Digital web-site. The download is free of charge:</p>
|
||
<ul>
|
||
<li><a href="http://www.nero.com/eng/company/about-nero/nero-aac-codec.php">http://www.nero.com/eng/company/about-nero/nero-aac-codec.php</a></li>
|
||
</ul>
|
||
<p> <br />Simply scroll down, click the "I agree" button, and enter <code>user@example.com</code> when asked for an e-mail address. Finally, click the "Download" button, which initates the download of the required <code>NeroAACCodec-1.5.1.zip</code> file.</p>
|
||
<p><em>Note:</em> Although the ZIP file is called <code>NeroAACCodec-1.5.1.zip</code>, it actually contains version <strong>1.5.4.0</strong> of the Nero AAC encoder software. Please check the included <code>changelog.txt</code> to verify this!</p>
|
||
<p><img src="img/lamexp/setup_3a.png" alt="Figure" /></p>
|
||
<p> <br />Now open the downloaded ZIP file with your favourite file archive software (we recommend using <a href="http://www.7-zip.org/">7-Zip</a> or <a href="http://www.rarlab.com/download.htm">WinRar</a>) and navigate to the "win32" sub-directory.</p>
|
||
<p><img src="img/lamexp/setup_3b.png" alt="Figure" /></p>
|
||
<p> <br />Finally, <em>extract</em> all the three files <code>neroAacDec.exe</code>, <code>neroAacEnc.exe</code> and <code>neroAacTag.exe</code> into the LameXP installation directory. That is the directory where your LameXP executable file, i.e. <code>LameXP.exe</code>, is located.</p>
|
||
<p><em>Note:</em> By default, the LameXP installation directory is either <code>C:\Program Files (x86)\MuldeR\LameXP</code> or <code>C:\Program Files\MuldeR\LameXP</code>. However, this can be changed by the user during the setup process.</p>
|
||
<p><img src="img/lamexp/setup_3c.png" alt="Figure" /></p>
|
||
<p> <br />Once the required Nero AAC files have been put into the proper place, simply <em>restart</em> LameXP in order to enable the AAC encoding support!</p>

<p> <br />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.</p>
|
||
<p><img src="img/lamexp/tutorial_1c.png" alt="Figure" /></p>
|
||
<p> <br /><em>Did you know?</em> Files can also be added via <a href="http://en.wikipedia.org/wiki/Drag_and_drop">Drag & Drop</a>. 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).</p>
|
||
<h2 id="output-directory"><span class="header-section-number">4.2</span> Output Directory</h2>
|
||
<p>Next, you need to choose the <strong>output directory</strong>, 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.</p>
|
||
<p><em>Note:</em> 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.</p>
|
||
<p><img src="img/lamexp/tutorial_2a.png" alt="Figure" /></p>
|
||
<p> <br />Sometimes you may wish to store the converted files in a <em>new</em> (sub-)folder. In this case, simply click the "Make New Folder" button, enter the desired folder name and hit the "OK" button.</p>
|
||
<p><img src="img/lamexp/tutorial_2b.png" alt="Figure" /></p>
|
||
<p> <br />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.</p>
|
||
<p><img src="img/lamexp/tutorial_2c.png" alt="Figure" /></p>
|
||
<p> <br /><em>Did you know?</em> 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.</p>
|
||
<h2 id="compression-settings"><span class="header-section-number">4.3</span> Compression Settings</h2>
|
||
<p>Finally, you need to choose your <strong>compression settings</strong>. First, and most important, you must decide for an output <em>audio format (encoder)</em>. Depending on your needs and preferences, you can choose between <a href="http://en.wikipedia.org/wiki/MP3">MP3</a>, <a href="http://en.wikipedia.org/wiki/Vorbis">Ogg/Vorbis</a>, <a href="http://en.wikipedia.org/wiki/Opus_%28audio_format%29">Opus</a>, <a href="http://en.wikipedia.org/wiki/Advanced_Audio_Coding">AAC/MP4</a>, <a href="https://xiph.org/flac/">FLAC</a> and others.</p>
|
||
<p><em>Note:</em> If you are uncertain which audio format to choose, then <a href="http://lifehacker.com/5927052/whats-the-difference-between-all-these-audio-formats-and-which-one-should-i-use">this article</a> by Lifehacker is a good starting point. Also see the <a href="http://en.wikipedia.org/wiki/Comparison_of_audio_coding_formats">comparison of audio coding formats</a> on Wikipedia. If still uncertain, just go with good old MP3 😉</p>
|
||
<p><img src="img/lamexp/tutorial_3a.png" alt="Figure" /></p>
|
||
<p> <br />Once you have decided for an audio format, you need to choose a <em>rate-control</em> 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.</p>
|
||
<p><em>Note:</em> 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 <a href="http://en.wikipedia.org/wiki/Variable_bitrate">variable bitrate</a> encoding.</p>
|
||
<p><img src="img/lamexp/tutorial_3b.png" alt="Figure" /></p>
|
||
<p> <br />Last but not least, you need to choose the desired target <em>bitrate</em> or <em>quality-level</em>. 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.</p>
|
||
<p><em>Note:</em> 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.</p>
|
||
<p><img src="img/lamexp/tutorial_3c.png" alt="Figure" /></p>
|
||
<p> <br /><em>Did you know?</em> 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.</p>
|
||
<h2 id="processing"><span class="header-section-number">4.4</span> Processing</h2>
|
||
<p>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!</p>
|
||
<p><img src="img/lamexp/tutorial_4a.png" alt="Figure" /></p>
|
||
<p> <br />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 😉</p>
|
||
<p><em>Note:</em> 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.</p>
|
||
<p><img src="img/lamexp/tutorial_4b.png" alt="Figure" /></p>
|
||
<p> <br />The "Processing" dialogue is going to turn <em>green</em>, 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 <em>red</em> instead.</p>
|
||
<p><img src="img/lamexp/tutorial_4c.png" alt="Figure" /></p>
|
||
<p> <br /><em>Did you know?</em> 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.</p>

<p>While LameXP originally was written in Delphi/Pascal, the current version 4 series of the software has been re-written in the <a href="http://en.wikipedia.org/wiki/C%2B%2B"><strong>C++</strong></a> programming language. LameXP v4 uses the <a href="http://www.qt.io/"><em>Qt cross-platform application framework</em></a> and provides full <a href="http://en.wikipedia.org/wiki/Unicode"><em>Unicode</em></a> support. Furthermore, LameXP is tightly coupled with the <a href="https://github.com/lordmulder/MUtilities"><em>MUtilities</em></a> library, a vast collection of "utility" routines and classes to extend the Qt framework. Build files are currently provided for <em>Microsoft Visual Studio</em> only. Linux support is currently provided via <a href="https://www.winehq.org/"><em>Wine</em></a>; a native Linux port of LameXP is planned for a future version.</p>

<h2 id="qt-as-static-libraries"><span class="header-section-number">6.3</span> Qt as Static Libraries</h2>
|
||
<p>In order to create a "fully static" build of LameXP, i.e. a build that does <em>not</em> 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 <em>does</em> provide pre-compiled Qt libraries. However, they only provide DLL versions, they do <em>not</em> 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:</p>
|
||
<ol>
|
||
<li><p>Make sure <em>Visual Studio 2013</em> with Update-4 (or later) is installed</p></li>
|
||
<li><p>Make sure <em>Strawberry Perl </em>for Windows and <em>Python 2.7</em> are installed</p></li>
|
||
<li><p>Download and extract the <em>Qt 4.8.x</em> source code package (e.g. to <code>C:\QtSources\4.8.x</code>)</p></li>
|
||
<li><p>Edit the file <code>mkspecs\win32-msvc2010\qmake.conf</code> from your Qt Sources directory as follows:</p>
|
||
<ul>
|
||
<li><code>Old: QMAKE_CFLAGS_RELEASE = -O2 -MD</code><br /></li>
|
||
<li><code>New: QMAKE_CFLAGS_RELEASE = -O2 -MT <more optimization flags here></code><br /></li>
|
||
<li><code>Old: QMAKE_CFLAGS_RELEASE_WITH_DEBUGINFO += -O2 -MD -Zi</code><br /></li>
|
||
<li><code>New: QMAKE_CFLAGS_RELEASE_WITH_DEBUGINFO += -O2 -MT -Zi <more optimization flags here></code></li>
|
||
</ul></li>
|
||
<li><p>Open a new command window (<code>cmd.exe</code>) – use this very same console for all upcoming steps!</p></li>
|
||
<li><p>Add <em>Strawberry Perl</em> to your PATH (e.g. <code>set PATH=C:\strawberry\perl\bin;%PATH%</code>)</p></li>
|
||
<li><p>Add <em>Python 2.7</em> to your PATH (e.g. <code>set PATH=C:\python27;%PATH%</code>)</p></li>
|
||
<li><p>Run <code>vcvarsall.bat x86</code> form your Visual C++ install directory - within the same console!</p></li>
|
||
<li><p>Change the current directory to the <em>Qt Sources</em> path (e.g. <code>C:\QtSources\4.8.x</code>)</p></li>
|
||
<li><p>Run <code>configure.exe -release -static -ltcg -qt-zlib -qt-libpng -qt-libjpeg -qt-libtiff -qt-libmng</code></p>
|
||
<ul>
|
||
<li>Hint: For Visual Studio 2013 you currently need to add <code>-platform win32-msvc2012</code> too</li>
|
||
</ul></li>
|
||
<li><p>Now the makefiles should have been generated, so simply enter <code>nmake /B</code> and be patient - voilà!</p></li>
|
||
<li><p>The build process is going to take good amount of time. Once it is done, make sure you got all needed libs:</p>
|
||
<ul>
|
||
<li><code>lib\qtmain.lib</code><br /></li>
|
||
<li><code>lib\QtCore.lib</code><br /></li>
|
||
<li><code>lib\QtGui.lib</code><br /></li>
|
||
<li><code>lib\QtSvg.lib</code><br /></li>
|
||
<li><code>lib\QtXml.lib</code><br /></li>
|
||
<li><code>plugins\imageformats\qico.lib</code><br /></li>
|
||
<li><code>plugins\imageformats\qsvg.lib</code><br /></li>
|
||
<li><code>plugins\imageformats\qtga.lib</code></li>
|
||
</ul></li>
|
||
<li><p>Put all the static *.lib files into the <code>Prerequisites\qt4_static\lib</code> directory</p></li>
|
||
<li><p>ImageFormat plugins go to <code>Prerequisites\qt4_static\plugins\imageformats</code></p></li>
|
||
<li><p>Congratulations, you should now be prepared to build the <code>Release_Static</code> configuration of LameXP 😊</p></li>
|
||
</ol>
|
||
<p> <br /><em>Note:</em> Static libraries only work with the exactly same compiler (version) they were built with!</p>
