{{From|https://help.ubuntu.com/community/Audacity}} {{Languages|UbuntuHelp:Audacity}} Audacity is a free, open source application for recording and editing audio. For more information, see the [http://audacity.sourceforge.net/ Audacity project home page]. == Installing Audacity == Audacity is not installed by default in Ubuntu. To start using Audacity, install the package <code><nowiki>audacity</nowiki></code> from the <code><nowiki>Universe</nowiki></code> software channel. For more information on installing packages, see [[UbuntuHelp:InstallingSoftware|InstallingSoftware]]. Once installed, click ''Applications -> Sound & Video -> Audacity'' to start Audacity. == Troubleshooting == After installation, you may receive the error message "''Error Initializing Audio''" with the explanation "''There was an error initializing the audio i/o layer. You will not be able to play or record audio. Error: Host error.''" To start Audacity without this error, press the <code><nowiki>Alt + F2</nowiki></code> keys on your keyboard and type the following into the box which appears: <pre><nowiki> gksudo audacity </nowiki></pre> If Audacity now starts without the error message, you can alter its menu entry with the new command by using the Alacarte Menu Editor. To start Alacarte, select ''Applications -> Accessories -> Alacarte Menu Editor''. If this method does not work, you can alternatively press the <code><nowiki>Alt + F2</nowiki></code> keys on your keyboard and type: <pre><nowiki> aoss audacity </nowiki></pre> This will run Audacity through the ALSA sound wrapper, instead of Audacity's default, OSS. For more information, see [[UbuntuHelp:alsa-oss|alsa-oss]]. == Locating libmp3lame.so When Exporting MP3 Files == By default, the library libmp3lame.so is not installed in Ubuntu. To install this library, install the package <code><nowiki>liblame-dev</nowiki></code> from the <code><nowiki>Multiverse</nowiki></code> software channel. (For more information on installing packages, see [[UbuntuHelp:InstallingSoftware|InstallingSoftware]].) When Audacity asks you to locate libmp3lame.so, you will be able to locate it in <code><nowiki>/usr/lib</nowiki></code> and export MP3 files. == Installing the Audacity Beta Version == This article pertains to the stable releases of Audacity. If you'd like to install the beta version of Audacity, see [[UbuntuHelp:InstallingAudacityBeta|InstallingAudacityBeta]]. ---- [[category:UbuntuHelp]]
