Download Audacity 2.4.2

Version 2.4.2 of Audacity has been released. Available for Windows, Linux, and macOS, this open source audio editor can record sound, import and export wav, aiff, ogg, and mp3 files. The program has an unlimited undo function and also has a large collection of effects on board, such as fade-in and fade-out, echo, tempo change and noise reduction. More effects can be added easily as the program supports both vst and ladspaplugins. The release notes for this release can be found below.

Reset Configuration|Easy configuration reset

A new command has been added to the Help menu: Help > Reset Configuration. This resets your Audacity configuration, preferences, export settings and toolbars, to default settings.
Note: Be aware that 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.

MP3 exports without padding

MP3s are now exported from Audacity with no padded (unwanted) short silence at the beginning and end of the MP3.
This was done as part of the work in fixing long-standing Bug #421
