Well, a Red Book compliant CD is 74 minutes, but some CDs out there are even longer. Some of them will even play on a compliant player ;-) And most discs don't use 100% of capacity anyway. Red discs read 75 2352-byte sectors per second, which actually turns out to be nearly 800MB per disc maximum. (this is more than a standard Yellow Disc because Red Discs have less forward error correction). Data-wise, I see a bit less than 2:1 compression on most music with FLAC. Classical and ambient material compresses more. My "three CDs per gig" rule of thumb is based on my personal CD collection, but I find that other people's experience is generally in this area. The then-present sampling rate for CDs was the same as it is now: 44,100 16-bit samples per second per channel. This is the Red Book standard. New formats (e.g. SACD and DVD-Audio) change both the quantization resolution as well as the sample rate, but those won't play on a CD-DA player, and I don't believe the Squeezebox supports those standards (yet). -- rudholm ------------------------------------------------------------------------ rudholm's Profile: http://forums.slimdevices.com/member.php?userid=2980 View this thread: http://forums.slimdevices.com/showthread.php?t=22854 _______________________________________________ Discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
