Audacity is a free, easy-to-use, multi-track audio editor and recorder for Windows, Mac OS X, GNU/Linux and other operating systems. The interface is translated into many languages.

Audacity is free software, developed by a group of volunteers and distributed under the GNU General Public License (GPL). Free software is not just free of cost (like "free beer"). It is free as in freedom (like "free speech"). Free software gives you the freedom to use a program, study how it works, improve it and share it with others. For more information, visit the Free Software Foundation.

Programs like Audacity are also called open source software, because their source code is available for anyone to study or use. There are thousands of other free and open source programs, including the Firefox web browser, the LibreOffice or Apache OpenOffice office suites and entire Linux-based operating systems such as Ubuntu.

    Audacity is great! I use it at Church to clip, modify volume levels, and filter out noise for sermons and music. I also used it to shorten the duration of a song by 8 seconds without changing the pitch to match the duration of a video of another version of the song. I have Roxio Creator NXT 2. The Roxio Sound Editor and Audacity programs are essentially equivalent in functionality and ease of use. Both programs accept VST plugins. However, Audacity also supports LADSPA and Nyquist plugins. Nyquist is special in that the user can write their own plugins using only a text editor. The plugin is only a simple text file. Re-compiling Audacity or understanding Audacity source code is not needed.
