Asynchronous USB Audio
Is anyone working on adding asynchronous support to the USB Audio Class library? The current mbed implementation expects the sample clock to be locked to the USB frame clock, but that is not always easy to do and the USB Audio Class specification includes support for asynchronous clocks. I am specifically looking for support for asynchronous sources like a microphone input. I believe asynchronous sources are easier than asynchronous sinks because the device can adapt the buffer size as needed.
Does anyone have an example with an asynchronous USB audio source?
