Audacity is a free, easy-to-use audio editor and recorder for Windows, Mac OS X, GNU/Linux and other operating systems. You can use Audacity to:
- Record live audio.
- Convert tapes and records into digital recordings or CDs.
- Edit Ogg Vorbis, MP3, WAV or AIFF sound files.
- Cut, copy, splice or mix sounds together.
- Change the speed or pitch of a recording.
- Add new effects with LADSPA plug-ins.
- AC3, M4A/M4R (AAC), WMA and other formats supported using optional libraries.
System Requirements: Audacity runs best with at least 1 GB RAM and a 1 GHz processor (2 GB RAM/2 GHz on OS X 10.7 or later). Where Audacity is to be used for lengthy multi-track projects, we recommend a minimum of 2 GB RAM and 2 GHz processor (4 GB RAM on OS X 10.7 or later).
Waveform colorways -
You can optionally change the colorway of the waveforms displayed in your project. The setting is per track and not per project so you can have multiple colorways in the same project as in the image below.
Four colorways are available with the color selection made from the dropdown menu in the track's Track Control Panel.
"Save Other" reverts to "Export" in the File menu -
When we made the menu changes for 2.2.0 we introduced an entry into the File menu called "Save Other" which led to a sub-menu for exporting various audio formats.
Many users were confused by this change and found it hard to find where they could export audio from. So for 2.2.1 we have changed that menu entry to be File > Export.
Opening a second project from Mac's Finder produces a second inaccessible instance of Audacity.
Crash applying certain chain files.
Preview fails when selection extends before zero.
Auto-scroll stopped working in 2.2.0.
Using File > Open to import audio gives wrong zoom level and no scroll bar slider.
Updated message translations for nineteen languages.
