Audacity is a free, open source digital audio editor and recording application. Edit your sounds using cut, copy, and paste features (with unlimited undo functionality), mix tracks, or apply effects to your recordings. The program also has a built-in amplitude-envelope editor, a customizable spectrogram mode, and a frequency-analysis window for audio-analysis applications. Built-in effects include bass boost, wah wah, and noise removal, and the program also supports VST plug-in effects.
You can use Audacity to:
- Record live audio.
- Record computer playback on any Windows Vista or later machine.
- Convert tapes and records into digital recordings or CDs.
- Edit WAV, AIFF, FLAC, MP2, MP3 or Ogg Vorbis sound files.

Audacity 3.0.2 release notes:
- As well as bug fixing we have also added more detailed reporting into Audacity to track down some hopefully not too common problems with the new format we introduced in 3.0.0. If you see an unexpected error message with a “Show Log…” button on it, please send the log to email@example.com, tell us how the problem happened, and whether it’s repeatable. We think, but do not know for sure yet, that some problems some users of 3.0.0 have had may be caused by networked drives which are slower than drives on the same laptop. We’ve increased a ‘timeout’ which should fix that.
- Users of the Macro feature in Audacity to process multiple files will find there is a new preference, Macro output, for where the results are put. The old way of doing things put the results with the files being processed. You can still do that if you want to keep doing it that way by adding an extra step in your macros.
- In parallel with 3.0.2 and 3.0.0 work, we’ve been doing a lot of other work on Audacity on another branch that is for the future and not in 3.0.2. Paul Licameli has been untangling dependencies in Audacity and making many graphs of the structure to guide what to untangle next. If code is hard to work with, we work more slowly. These changes to untangle the code should make Audacity more flexible, and make it easier to work with the code. We kept these changes out of 3.0.0 and 3.0.2, as the changes were substantial and the important aup3 work took precedence. Hopefully the more flexible cleaner structure will be a big win for future versions of Audacity.
- 3.0.2 has some simple to do but important bug fixes. The compressor effect was not working for longer selections. We were also very occasionally getting an error messages at start up of Audacity, requiring a restart of Audacity. You can read more about what we did for 3.0.2 on the New Features page of the manual.
