FFmpeg and 64-Bit

Audacity 2.4.2 for macOS is now a 64-bit application.
If you use the optional FFmpeg library you will need to download the 64-bit versions of them.

Screen Reader Version

Versions 2.1.2 to 2.4.2 of Audacity are not sufficiently accessible for visually impaired users who use VoiceOver, and not suitable for OS X 10.5 either, so we provide the older 2.1.1-screen-reader version instead.

Audacity 2.1.1-screen-reader .dmg file (38.61 MB, accessible version, Universal Binary for OS X 10.5 Intel/PPC Mac, includes user manual)

We do plan to make Audacity more accessible on Mac again in the future. We’re catching up with changes in the libraries we use.

Installation of Audacity

Double-click the downloaded DMG to mount it.
Drag the “Audacity.app” icon in the DMG window to the /Applications folder icon on the right. Alternatively, drag the “Audacity.app” icon to any other location of your choosing.
Do not double-click the “Audacity” icon in the DMG to launch Audacity from there.
Eject the DMG at bottom left of Finder, then launch Audacity.app from /Applications or from your chosen location.

Plug-ins: If you still have an “Audacity” installation folder for a version before 2.4.2, you will see working duplicates of Audacity’s shipped Nyquist plug-ins in the Generate, Effect or Analyze Menu. You may also see non-working duplicates of other previously shipped plug-ins. To clean up the duplicates please see: Installing and updating Audacity on Mac.

Before deleting the Audacity folder from a previous installation, remember to move any optional plug-ins you added to its plug-ins folder to the new Audacity Plug-Ins folder at ~/Library/Application Support/audacity/Plug-Ins.
