Fundamentals of USB Audio

Nice write-up on EDN. Explains how the USB Audio protocol does adaptive transfer rates based on information from the receiving device (the major advantage, I think, over S/PDIF). Also points out that a single USB 2.0 connection can support 10 channels of 24/192 audio at once.

Nice. I run 6 channels of 24/352.8 through USB all the time.
