Audio Units

Apple’s Audio Units are system level plug-in filters, generators and effects which can be applied to audio streams within a host application. Neutrino is an extremely capable Audio Units host, allowing an unlimited number of Audio Units to be chained in the Fx Chain.

Neutrino currently hosts Effect AUs only, it does not recognise Generator AUs.

A huge number of third parties have created Audio Units plug-ins. Today there are hundreds of AU plug-ins available, almost all of which can be used with Neutrino as well as many other applications on the Mac, including GarageBand and Logic Pro.

Neutrino has the ability to display all the major kinds of Audio Units user interfaces, native and Carbon.

Installing Audio Units

Audio Units are installed for all users by dragging them into /Library/Audio/Plug-Ins/Components. Alternatively, they may be installed for the current user only by installing them in ~/Library/Audio/Plug-Ins/Components.

You will need to relaunch Neutrino for newly installed Audio Units to be available in the FX Chain.
