About Audio Units

Overview

Audio Units is a plugin interface for connecting software effects and instruments to sequencers and other audio software. It was developed by Apple Computers and is available exclusively on Mac OSX. AU competes with the VST plugin architecture, which provides similar functionality. Its even possible to use VST plugins within an Audio Unit host using FXPansions VST to AU Adapter. Notable sequencers which support the Audio Unit standard include Apple's flagship Logic Pro and simplified version Logic Express and entry level Garageband. Other sequencers include Ableton Live, and Digital Performer.

AU Instruments

AU instruments generate sound in response to MIDI input from a sequencer or keyboard. Instruments fall into two main categories; samplers - which play back recorded sounds, and synthesizers - which generate sound algorithmically.

AU Effects

AU effects process incoming audio to produce an effected output. There are many kinds of effects, including reverb, auto-panner, delay compression, distortion and filtering.
