Audacity is for Windows, Mac and Linux desktop machines. There is no version of Audacity for Android or iPhone.
Mac OS X
Audacity 2.2.0 provides partial support for macOS 10.12 (Sierra). Gatekeeper on macOS 10.12 can cause some plug-ins to go missing and other problems. Full details at https://wiki.audacityteam.org/wiki/Partial_Support_for_Mac_Sierra_in_2.1.3.
- Audacity 2.2.0 is for Intel Macs running OS X 10.6 and later and macOS. There are legacy versions for older OS X at http://audacityteam.org/download/legacy-mac/.
- Audacity 2.2.0 requires the CPU to support the SSE2 instruction set which should be available on any Intel hardware produced after 2001 and any AMD hardware produced after 2003. To check what SSE levels your CPU supports, you can install CPU-Z. If your hardware only supports SSE, you may download Audacity 2.0.6 (ZIP, not installer) by clicking this link.
- 2.2.0 does not officially support Windows XP.
- Linux support is tested on Ubuntu Linux.
- Audacity may compile on Gentoo, Debian, Mint.
- Audacity does not currently compile on SuSE Linux.
See our list of issues for much more detail of issues with Audacity 2.2.0.
- Below are listed what we believe are the most common and important issues with 2.2.0 for most users.
- Timer Record may not reliably stop the recording on some machines. The Elapsed and Remaining Time counters may stop counting. In this case it will be necessary to force quit Audacity.
- On a few affected machines, the problem can be avoided if you leave focus on Audacity or ensure it has focus when recording is due to end.
(Linux) PULSE Audio
- PulseAudio is not reliable when used with Audacity on Linux. Playback or recording may freeze, recording dropouts or fast playback may occur when using PulseAudio.
- Freezes may be caused by repeatedly starting and stopping playback or recording in quick succession (or by holding down the Play or Record button).
- Workarounds: Try launching Audacity from the terminal with the pulse latency set to 30 ms in an environment variable:
- env PULSE_LATENCY_MSEC=30 audacity
- If you get underruns noted in the terminal, try a higher number in the PULSE_LATENCY_MSEC command. If the problem is unchanged, try a lower number.
- Alternatively, bypass pulseaudio by setting the playback and recording device to an ALSA (hw) choice in Device Toolbar. More help with this can be found here.
- The timing of notes during MIDI playback may sound erratic on some machines. Optimizing the system for low latency MIDI playback can help to reduce the inaccuracies.
- Far less of Audacity is properly accessible to visually impaired users than we would like. Currently the best supported platform for accessibility is Windows. We lost a lot of custom accessibility programming when we had to move to a more recent version of the wxWidgets library. A lot more detail about accessibility limitations can be found here
We track these and many other bugs in our 'bugzilla' database.
