Hmm, quickndirty calc for 90 minute tape at 64kbits =40megs or so. If
you can only get 32kbits then you still get 20megs... The sound
engineers among us can no doubt confirm bandwidth and S/N issues, but I
would have thought that at least 32kbits would be doable with a little
error correction ?
Maybe this isn't such a crap idea after all ;-)) (I still haven't
bought a backup device for my new PC).
