I started looking at the USB2 protocols for something
else, but gave up
when I saw how insanely complex it is even for relatively simple data
transfer. In the end, for my project, it was easier to convert the data
into an RS232 serial stream then use one of the standard serial-USB
converters.
Well, then you could design around a ft232 [1].
But would RS232 suffice for 8ch/24bit/44.1kHz (12Mbit/s) ?
Shall I interpret your answer as the main hurdle is not to convert
x channels at real time, but to get it into the computer?
Would a network connection solve that problem?
In that case the DACs and ADCs could reside on an embedded computer
and stream the sound data to/from the pc. And one could envision
such little things near each mic and ethernet cables or possible wifi
to the control room. Power-Over-Ethernet [2] could be helpful, and why
not throw in a pre-amp and plug it directly into the mic.
