What is AU Lab?

AU Lab is a digital mixing application that provides facilities for blending audio from the input of an audio device as well as audio generated by an Audio Unit Instrument or Generator. In addition, AU Lab can host Audio Unit effects and route audio through these effects.

The AU Lab Application

AU Lab is very efficient and has a very high performance and low overhead audio engine capable of supporting multiple outputs, full support for multichannel, and advanced routing features such as send buses and sidechain buses.

As the image above illustrates, the application provides MIDI clock facilities for audio units that support host clock synchronization, and an inspector that features a cocoa-based generic view of audio units that do not provide their own custom user interface. This inspector includes full support for preset management, and facilities for MIDI mapping of audio unit parameters.

Although AU Lab provides recording controls, it is not designed to be used for extensive recording. It is mainly designed as a platform reference Audio Unit host, and is designed for Audio Unit auditioning and live applications.
