Audio Units

From Audacity Wiki

This page describes support for Audio Units effect plug-ins in Audacity. Audio Units is a plug-in architecture developed by Apple and is only supported in Audacity Beta for Mac OS X.

[edit] Audacity support in current Betas

Place Audio Units plug-ins at:

• /Library/Audio/Plug-Ins/Components/ or
• ~/Library/Audio/Plug-Ins/Components/

As always, ~ means your home directory. Audacity should detect newly added Audio Units plug-ins on restart.

Like VST plug-ins in Audacity Beta, Audio Units effects display their full GUI interface by default, where one is provided. If interface difficulties arise, Audio Units can be limited to a tabular interface with sliders by clicking Audacity > Preferences: Effects and unchecking the option "Display Audio Unit effects in graphical mode". There are some screenshots of Audio Units plug-ins in Audacity here.

[edit] Issues

• AUMatrixReverb only outputs in stereo and needs a stereo track to work on, so cannot be used on a mono track.
