I need to record from as many as 40 microphones simultaneously on a single Windows 7 PC. These microphones will be present as USB audio adapters connected to powered USB hubs (so limited power isn't an issue.) I'd like to capture audio in PCM, 44.1khz, stereo, 16 bit.
Is this possible? Can Windows detect 40 microphones, and will I be able to access them simultaneously? Is there a maximum number of USB devices Windows can detect?
