Audacity 是一个自由开源的供录制编辑音频之用的应用程序。更多信息请参照： [http://audacity.sourceforge.net/ Audacity project home page].
== 安装 Audacity ==
Ubuntu默认不安装Audacity. 
想用Audacity的话, 这样安装
<pre><nowiki>
sudo apt-get install audacity
</nowiki></pre>
更多安装软体的方法请参照[[UbuntuHelp:InstallingSoftware|InstallingSoftware]].

安装完成后，点击 ''应用程序 -> Sound & Video -> Audacity''启动Audacity。
== Audacity 和 PulseAudio ==
从Ubuntu 8.04开始，ubuntu使用PulseAudio作为默认的音频服务。 你务必保证Audacity和PulseAudio不能同时使用声音设备。
=== 使用Pulse设备 ===
对于Ubuntu 9.04 以上的版本，在Audacity的首选项对话框里有列出"ALSA: pulse"一项。 请确保它被选中。 (若无 "ALSA: pulse"，请尝试 "ALSA: default"。) 现在Audacity录音和播放音频时都通过!PulseAudio，并且你也可以使用PulseAudio的一些特性了 (例如录制监视流).
==== Intrepid (8.10) ====
为了能够使用上面提到的"ALSA: pulse"设备，David Henningsson已经打包了修复过的软件包；可以通过添加他的PPA来使用。PPA: https://edge.launchpad.net/~diwic/+archive. 
=== 挂起 PulseAudio ===
如果上述方法无效,请使用这个命令启动Audacity:
"pasuspender -- audacity"
这将在您使用Audacity的时候暂时暂停!PulseAudio (使其他程序停止声音的输入/输出). 
== Troubleshooting xruns ==
XRuns are drop-outs and/or clicks in recording or playback that are caused by your computer doing other things than handling soundcard input/output buffers. In the Audacity layer you can try to increase the latency (edit -> preferences -> recording). 
== 导出MP3文件的时候定位libmp3lame.so ==
默认的情况下ubuntu没有安装libmp3lame.so库。请根据您的ubuntu版本并通过下面的表格来找出你要安装的软件包的名字。(更多安装软件的方法信息请看 [[UbuntuHelp:InstallingSoftware|InstallingSoftware]].)
* Dapper (6.06), Hardy (8.04): package <code><nowiki>liblame0</nowiki></code> from the <code><nowiki>Multiverse</nowiki></code> software channel.
* Intrepid (8.10), Jaunty (9.04), Karmic (9.10): package <code><nowiki>libmp3lame0</nowiki></code> from the <code><nowiki>Multiverse</nowiki></code> software channel.
* Lucid (10.04): package <code><nowiki>liblame0</nowiki></code> from the <code><nowiki>Multiverse</nowiki></code> software channel. Please note that Lucid regains the <code><nowiki>liblame0</nowiki></code> package name. This is just a virtual package provided by the real <code><nowiki>libmp3lame0</nowiki></code> package.
您可以在Edit -> Preferences... -> Libraries -> MP3 Export Library确认此库。
当Audacity问你libmp3lame.so在哪儿时，您可以在 <code><nowiki>/usr/lib</nowiki></code> 找到并且可以导出MP3文件了。
== 过时的信息 ==
下面的信息对7.10以前的版本有效。
=== 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''. Note that you will need to install Alarte first. See [[UbuntuHelp:InstallingSoftware|InstallingSoftware]].
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]].
=== 安装Audacity Beta版 ===
如果您在使用1.2.x版并想使用Beta版请参照[[UbuntuHelp:InstallingAudacityBeta|InstallingAudacityBeta]].
