What's New in version 2.4.2:

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. 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.

What's New in version 2.3.1:

Over 20 bugs fixed, and a few small improvements/changes to features (since 2.3.0):

  • That annoying message from Apple saying: '32-bit support will be going the way of the dodo', no longer shows when you install Audacity on Mac. The new 64-bit Audacity works with 64-bit libraries. To use FFmpeg or MP3 libraries with 64-bit Audacity, you will need to download the updated 64-bit versions.
  • On Windows, you may find that recording is disabled until you change Windows permissions for the microphone! That’s a security feature introduced by Windows. This affects all versions of Audacity, and affects many other audio programs.


Options and preferences:

  • Microfades are now an opt-in feature. They were always on in 2.3.0.
  • The advanced vertical zooming option is now available in the View->Zoom menu.
