Audacity Development Team - (Open Source)
Audacity is a multi-track recorder able to handle full projects, and an audio editor.
Audacity is a free audio processing software that supports the following file formats: WAV, AIFF, OGG and MP3, applying many filters to sound: silence suppression, echo or add special effects, noise suppression, mixing, distortion, reverb, pitch bend / shift and more.
It can cut audio files, delete or add rests, apply fading in / out audio files and treat separately the left / right channels. The program offers unlimited undo number and also the possibility to convert the records and old tapes to digital media.
Thanks to the integrated editor, you also have the ability to copy, paste and mix sounds together to create multitrack projects.
# Bug fixes
- Keyboard Preferences: Shortcuts for Generators, Effects and Analyzers were not exported. All imported shortcut changes were discarded.
- Equalization curves were corrupted in Graphic EQ mode after switching to/from Draw Curves or after running the effect then reopening it.
- Change Pitch displayed corrupted values when reducing pitch or editing "from" Frequency. Detection was very inaccurate at high sample rates.
- Bass Boost no longer clips if the track contains 32-bit audio.
- Auto Duck was excessively slow on older machines.
- (Windows) Exported MP3 comments tags were not seen by Windows programs.
- (Windows and OS X) Audacity crashed if you used system quit before file import was complete.
- (Linux) Equalization crashed Audacity if the XML file was corrupted.
- (Linux) When configuring effect parameters in "Edit Chains", "Preview" (not intended to be functional) caused a crash.
- (Linux) LICENSE.txt and README.txt were wrongly installed in /usr/local/share/doc instead of /usr/local/share/doc/audacity/ .
- Accessibility: ENTER did not toggle selectedness of a label track unless a label was selected.
- Numerous other interface fixes.
# Changes and Improvements
- New "Reverb" effect to replace GVerb, based on the original "Freeverb".

- Handle a bug in older iPods or some OS X applications that cause them to refuse AIFF files whose metadata contains an uneven number of characters,
- (Windows) Added support for "Windows WDM-KS" host which can provide very low latencies if you reduce "Audio to Buffer" in Recording Preferences.
- (Windows Vista and later) You can now record computer playback by choosing the new "Windows WASAPI" host in Device Toolbar then a "loopback" input.
- (Windows and Mac OS X): VST scanning dialog now replaced with a dialog for choosing which VST effects to load.
