Mac OS X
Beta version
System Requirements DownloadAudacity 1.3 Beta is our new, not quite finished, development version which will be the basis of our next "stable" version.
- Contains dozens of new, exciting features. Very occasionally, these might need final polishing or not be retained in later versions.
- Occasionally, a feature might not work as it did before, or might be temporarily disabled.
- Some parts of the program are not yet documented or translated into different languages.
If you are new to Audacity or computer audio programs, you may prefer the fully finished Audacity 1.2. Otherwise, please help our development effort by trying the Beta and send us your comments. Please mention your operating system, full details of any problems, and any features that need improvement or no longer work properly. You can install 1.3 and 1.2 on the same machine by installing them to different directories.
