Audacity for Mac

What's new in this version:

Easy configuration reset:
- A new command has been added to the Tools menu: Tools > Reset Configuration.
- This resets your Audacity configuration, preferences, export settings and toolbars, to default settings.
- This command acts immediately with no dialog and no choice of actions or chance to abort.
- Undo is not available for this command.
- User presets in Effects, Generators and Analyzers are left untouched, as are any Macros you may have created and plug-ins.
- Please see Reset Configuration for further details.
- MP3 exports and imports without padding
- Audacity now supports LAME's gapless playback info, allowing MP3s to be exported and imported without additional padding.
- Other applications that support the LAME tag, for example audio player applications, will be able to read MP3 files exported by Audacity without the padding.
