>>I don't know how much audio you can get per second of disk space. That's dependent on the type of recording and compression used. I believe 10MB per second of stereo CD sound is the uncompressed size. I believe that's higher than what you'd actually get though. I believe the Monterey has a hardware compression DSP chip on it that makes the size more managable. It's probably closer to the 4MB per second I mentioned earlier.<< I'm just happen to be doing lots compact disc digital audio to the *.WAV format. Yes, there is such software to convert the pure digital data from the regular CD disc (also overriding the copy protection bit that is used on all cds) This process results in a p e r f e c t copy of the CD, not having to recapture the sound by conventional mean (which degrades quality) ! ! Anyway, getting to the point: If 10 Mb/sec, then one minute would be a whopping 60 Mb! To be more correct, it would have to be ~10 Mb/ minute @ 16-bit / 44 Khz sampling / 2-track stereo . So an average five-minute song would be only ~50 Mb not 3 gigabytes ! ! >>The PCI setup has a 13.5 MB/sec transfer rate that would easily handle CD quality output for a sustained period of time. It's probably overkill for audio though.<< I'm just curious is it 13.5 Mb or 132 Mb/sec? Are you talking about burst or sustained transfer rate? I think it would be 132 Mb for the bus alone (PCI rev. 2 bus) . Too bad that even today fastest SCSI-II & III * can handle up to ~20 Mb/sec. So the bus might be overkilling the SCSI-xx controller. *SCSI-III: I'm guessing. If someone know more about the new SCSI-3 specs, please give more insights. TSL
