<div class="intro">This page provides instructions for installing and updating Audacity on Linux computer platforms.
<ul><li>In addition to basic Audacity you may wish to install the optional <a href="#linlame">LAME</a> <i><b><a href="glossary.html#mp3" title="Glossary">MP3</a></b></i> encoding software</li>
<li>Also the optional <a href="#linff">FFmpeg</a> library which allows Audacity to import and export a much larger range of audio formats including <i><b><a href="glossary.html#aac" title="Glossary">M4A (AAC)</a></b></i>, AC3 and <i><b><a href="glossary.html#wma" title="Glossary">WMA</a></b></i> and also to import audio from most video files. </li>
<li>Note carefully that simply re-installing Audacity will <i><b>not</b></i> clear and reset your Audacity settings for preferences and plugins. For instructions on how to achieve this please see <a href="#purge">Reset Audacity Settings</a>.</li></ul>
<div class="note">If you are updating from Audacity 2.x or earlier please read <b><a href="updating_from_audacity_2.x_to_audacity_3.html" title="Updating from Audacity 2.x to Audacity 3.x">Updating from Audacity 2.x to Audacity 3.x</a></b> as there was a major change to the project file structure when Audacity 3.0.0 was introduced. </div>

<h2><span class="mw-headline" id="Installation_instructions">Installation instructions</span></h2>
<p>The recommended way to install software for most GNU/Linux and Unix-like Desktop distributions, is to install from the official distribution repository using a <a rel="nofollow" class="external text" href="https://en.wikipedia.org/wiki/Package_manager">package manager.</a> Most distributions provide Audacity packages.
</p><p>Alternatively you can build the latest Audacity tagged release from our <a rel="nofollow" class="external text" href="http://www.audacityteam.org/download/source/">source code</a>.
</p>
<div class="note">Some old versions of Audacity were incorrectly built. The minimum recommended version of Audacity for Linux is 2.1.2<br />
<b>Note that this Manual only relates to the <a rel="nofollow" class="external text" href="http://www.audacityteam.org/download/source/">current release of Audacity</a></b>.</div>
<div id="sysreq"></div>
<h3><span class="mw-headline" id="System_Requirements">System Requirements</span></h3>
<p>We recommend using the latest version of GNU/Linux from your distribution that is compatible with your hardware specifications. Audacity will run best with at least 1GB RAM and a 2 GHz processor. Because it was originally written when computers were less powerful, you may be able to run it on much less powerful hardware too. Simple recording is possible on a 700 MHz Raspberry Pi, using a USB Microphone. However, Pi operating systems are not officially supported and Audacity may be less stable on them than on desktop operating systems.
</p>
<div id="compatible_projects"></div>
<h3><span class="mw-headline" id="Projects_saved_by_old_versions_of_Audacity">Projects saved by old versions of Audacity</span></h3>
<p>Current Audacity can open project files saved by versions of Audacity 1.2.x and later, including 2.x.x.
</p><p>These will be converted to the 3.x AUP3 single file format. See <a href="audacity_projects.html#open" title="Audacity Projects">Managing Audacity Projects</a> for more details.
</p><p><br />
</p>
<div id="updates"></div>
<h2><span class="mw-headline" id="Check_for_Updates">Check for Updates</span></h2>
<p>You can check to see if you have the latest version of Audacity by using <span class="menu">Help &gt; Check for Updates...</span>.
</p><p>This takes you to the <a rel="nofollow" class="external text" href="http://audacityteam.org/download/">Download page</a> of the Audacity website where you can check what the latest release version of Audacity is.
</p><p>You can then compare the latest release with the version you have now as shown by using <span class="menu">Help &gt; About Audacity...</span>.

<p>You may download (or compile) and install a compatible version of the FFmpeg or libav library for your purposes then <a href="#locate">locate</a> it in Libraries Preferences.
</p><p>If you download a pre-built library, this might be either a "shared" or "static" build. A static build consists of a single libavformat library, whereas a shared build has at least three libraries (libavformat, libavcodec and libavutil). It is recommended to use a shared build, but Audacity will also work with a static build.
</p><p>To build FFmpeg, obtain the source code from the <a rel="nofollow" class="external text" href="http://ffmpeg.mplayerhq.hu/download.html">FFmpeg project</a>. To build libav, obtain the source code from the <a rel="nofollow" class="external text" href="https://libav.org/">libav project</a>. Configure the build with <i>--enable -shared</i> so that it builds the necessary shared object library (.so) files. If required, you can also configure to enable or disable particular encoding/decoding libraries. When you build Audacity from our <a rel="nofollow" class="external text" href="http://audacityteam.org/download/source">source code</a>, it should link to the installed FFmpeg headers.
