SONY are selling professional "direct bitstream" recorders. They may
even be working on processors/mixers for that format. "direct bitstream"
(at least I think that's the name) is an ultra-high-frequency sampling format
with single-bit data. The signal can be reconstructed with a simple capacitor
and resistor filter, or something more fancy if you're into that...
I very briefly looked at what I could find out about the format a year or so
ago, and it's not immediately obvious how you would do even such simple
processing as mixing on it -- anyone have any clues?
