As I have not yet started any coreaudio programming I have a general
question:
If you read from a digital source, you can obviously also transmit control
data.
An example: instead of just setting/reading the copy-prohibit-flag, some
vendors do viable things with their S/P-DIF-implementations in
consumer-level devices - they transmit track boundaries and such in the
stream headers so you don't have to set them manually.
AFAIK there is currently one sound card dealing with track boundaries (and
only drivers for "another" OS supporting that feature).
IMHO future high bandwidth audio protocols could gain a lot of that. One can
see this as timestamping has become quite common in USB MIDI.
Does the coreAudio API support modifying/analyzing IO stream headers in such
a general sense?
Best Regards,
Bernd
