Nightly Builds

From Audacity Wiki
Jump to: navigation, search
Nightly builds are automated 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 this page.

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.

Binaries for Mac OS X 10.4 or later

  • Every night at 03:15 (GMT) an alpha build in "Release" configuration is automatically made from the latest GIT trunk.
  • Every Sunday night at 04:15 (GMT) a weekly alpha build in "Debug" configuration is automatically made from the latest GIT trunk. These are slower builds that can be used to trace crashes and other problems.

Both builds are universal binaries. The most recent nightly release and weekly debug builds can be downloaded from the top of this page.

GNU / Linux

Daily PPA installation packages for Ubuntu are now being built from Audacity's Git repository. However these builds are against wxWidgets 3.0 which is not yet supported by Audacity Team, and so these builds may contain wx3-related bugs.

If you require these builds, follow the instructions on to add the PPA to Ubuntu and authenticate it before installing a package for the first time. If you wish to disable updates, disable the PPA repository at System > Administration > Update Manager, click Settings then choose the Other Software tab.

Otherwise you may build WxWidgets 2.8.12 (supported by Audacity) and then clone our Git repository and compile our latest development code against wx2.8.12. To do this we recommend reading Developing On Linux and our Compiling Audacity Step by Step Guide.


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 Vista SP1 or Mac OS X 10.4.11 PPC)

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).
