Technical Notes: Hardware
The I/O Kit, part of Darwin, is the device driver subsystem for Mac OS X. It supports rapid driver development, streamlining the development of audio hardware. Core Audio's Hardware Abstraction Layer (HAL) serves as the interface between an audio device driver and an audio application. The HAL supports native multichannel audio in a manner scalable for future high-resolution formats as they arise. Developers can use these programming interfaces to create audio devices that are compatible with Apple products.
