I think he meant to send any data directly through the MAS as raw pcm,
i.e. bypassing the mp3 decoding...
this is only possible if we can write, compile, and upload the MAS's own
type of firmware to it's internal RAM, which we don't have the tools or
knowledge to accomplish, and apparently anybody who does is under NDA...
untill somebody with experience with such things comes forward, there's
not much, if anything, we can do in this respect.
