Hardware Music & Audio Documentation
System-level services in Mac OS X streamline the development process for audio developers, as well as for application developers who want to incorporate music and other audio media into their products. Core Audio provides native multi-channel audio in a manner scalable for future high resolution formats as they arise. Audio Units and Audio Unit Graph (AUGraph) APIs provide a plug-in architecture for both DSP (audio in/audio out) and virtual instruments (MIDI in/audio out). MIDI services allow for multi-port MIDI capability.
