Possibly it would, although it may need to be a rather faster ATRAC.
Remember this whole thread started because I suggested that it would be
better to implement ATRAC encoding at the PC rather than at the MD because
it would free up the USB bus. Perhaps encoding on the PC shouldn't be in
software but, as you suggest, as hardware. Perhaps a modified form of sound
card that outputs a special ATRAC encoded stream at high speed.

Yes, but the difference there is you are attempting to emulate the whole PSX
system, where-as I was merely suggesting that this be an alternative method
of encoding to allow high-speed recording to MD via an interface (probably
USB). Al I am in reality suggesting is a new version of the Sony MDH-10
drive but running from a USB port with the ATRAC encoder on the PC rather
than in the unit.
Even if a high-speed ATRAC chip is used as opposed to software ATRAC, I
think the encoder would be better off at the PC end as this allows more
utilisation of the limited bandwidth USB ports.
