|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.
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 still being made from the Audacity SVN repository. However Audacity development moved to Git after Audacity 2.1.0 was released so these daily builds no longer offer the current Audacity code, but what amounts to 2.1.0 release with a few cosmetic changes.
If you require these builds, follow the instructions on https://launchpad.net/~audacity-team/+archive/ubuntu/daily to add the PPA to Ubuntu and authenticate it before installing a package for the first time. To disable the no-changes updates, disable the PPA repository at , click then choose the tab.
- 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)
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).
