On the last point, >an 8-bit DAC should be out of this word for musical sound synthesis, >but we have to specify which direction :-). I've heard digital audio from an 8-bit DAC and it sounded GREAT. You could limit down to it 5 or 4 bits and it would still sound good. The demo I heard used a Billy Joel compact disc going through a 10-bit DAC that had the capability of switching off as many bits as you wanted. You could still hear that it was Billy Joel even with 3 bits, but it was not as good. When dither was added, it sounded as good as it did with 5 or 6 bits although there was some noise added. It would be fantastic if you could get the Amiga to play digital music if it had enough memory (or at least a fast CD drive). --- Andy Toy Mapping Analysis and Design Group, University of Waterloo, Waterloo, Ontario, CANADA, N2L 3G1 UUCP: ...!{utzoo|decvax|ihnp4|clyde|allegra|linus}!watmath!watnot!atoy ARPA: atoy%watnot%watmath%waterloo.csnet@csnet-relay.arpa CSNET: atoy%watnot%watmath@waterloo.CSNET BITNET: atoy at watdcsu
