I think you're mostly right. If you want to be able to preserve enough bandwidth for music, you're talking about kilobytes per second of audio, but yeah, you could just store the streams from each mic in the array, so multiply the bitrate by the array size. And it's probably possible to find ways to save bandwidth with joint encoding.
