Spread the love

Version 3.0.0 of Audacity is in development and a second release candidate 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.


  • Audacity now uses ‘aup3’ format, with all audio in one file, rather than the previous ‘pile of file’ format. We are using the SQLite library to manage the contents of this file. Too many users were previously getting caught out by copying part of the project only, when backing up.
  • ‘Backup Project’ command replaces ‘Save Lossless Copy of Project’ and ‘Save Compressed Copy of Project’
  • Added Corsican and Marathi languages.
  • ‘Label Sounds’ replaces ‘Sound Finder’ and ‘Silence Finder’.
  • Added Import and Export of Macros.
  • Added Attack, Hold and Delay times to Noise Gate.
  • Added Multi-View option to Track Preferences
  • Added hidden (bindable to shortcuts) commands for repeating last generator, analyzer or tool. Previously only most recent effect could be repeated.
  • Upgraded Nyquist to 3.16
