For USB audio device developers:
I have published a comprehensive guide to developing class compliant USB audio devices for the Mac here: http://developer.apple.com/mac/library/technotes/tn2010/tn2274.html
Topics include:
- AppleUSBAudio class driver overview
- Supported USB Audio 1.0& 2.0 features
- Engine/stream architecture, sample synchronous i/o streams
- Endpoint synchronization types
- How to calculate max packet size
- How the driver determines what controls to publish
- Device originated status interrupts
- Descriptive naming of device/channels
- Ways to extend the class driver
Please keep an eye on this tech note as we will continue to update it with additional driver information and enhancements as they become available.
Thanks,
Alison
