Its a bit unclear who you are quoting in this part, perhaps Hartley, perhaps the mastering engineer, perhaps its your comments. More the the point. The math of converting SACD's DSD to PCM is not complex at all. Its trivial. The main selling point of DSD was that it was so simple, a clueless chip could do it. Its just one bit sampling at a very high rate. Nothing magic. The real main selling point of DSD was that it was controlled by Sony, not that it was technically superiority in any way. DSD died because it would have required all of the recording studios in the world to change out their digital systems, which were PCM. At the time, studios had just recently migrated from 2" tape to digital, and the industry business model was imploding. No sane studio owner wanted to put tons of money into an upgrade based on future promisses. -- Pat Farrell http://www.pfarrell.com/ _______________________________________________ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
