Nightly Builds

From Audacity Wiki
Jump to: navigation, search
Nightly builds are alpha builds from the latest development code. Although by their nature these builds are unstable and may contain bugs, we encourage everyone to test out our latest ideas and report problems to us. This will directly help to improve the quality of the following release.
Warning icon

Although major problems with alpha builds are rare, they should not be used as your production version of Audacity. Please back up saved projects and/or export your work regularly as WAV files.


Binaries for Windows XP/Vista/Windows 7/Windows 8

Frequent (but not necessarily nightly) alpha builds in "Release" configuration (.zip) are available from the latest GIT trunk. The most recent nightly release build can be downloaded from the top of

Instructions (zip): Extract the contents of the zip to a new folder and double-click audacity.exe from that new folder to launch it. It will not affect any other installed version of Audacity you may have.

Universal Binaries for Mac OS X 10.4 or later

GNU / Linux

Daily alpha build installation packages for Ubuntu (based on Git trunk) are at Please check the build status top right of the daily builds page. If you require these builds, follow the instructions on that page to add the PPA to Ubuntu and authenticate it before installing a package for the first time.

If after installing the PPA you wish to disable further updates, disable the PPA repository at System > Administration > Update Manager > Settings > Other Software or similar.

See Developing On Linux and our Compiling Audacity Step by Step Guide if you wish to compile the latest Audacity code yourself.


Your feedback on how new features work and on the stability of the builds is invaluable to us. Please check Release Notes for known issues. Please report new issues found to our feedback address.

Please remember to tell us:
  • The date of the build (Help > About Audacity, or Audacity > About Audacity on Mac)
  • The exact operating system you are using (for example, Windows 7 SP1 or Mac OS X 10.10.4).

Build Automation

If at some future date we want to automate the building of Audacity on multiple platforms (using virtualisation), a server we could use is at OSUOSL. According to their FAQ, the required guest operating systems are Linux-based (plus there will be two OS X machines available for testing).
