The better your ability to control the transport's motor speed, the smaller the buffer can be. Cost issues dictate how you balance this equation. pvadbx;146005 Wrote: > If your statement is true, why do CD players of similar componentry to > the SB3 sound so much worse? What do you mean, "if my statement is true"? This is how CD players work, and always have done. You can't argue against it by raising personal doubts over the engineering feasibility and citing empirical observations about sound quality. There are plenty of reasons why an SB3 might sound different to a CD player that have nothing to do with the way the data is acquired from the storage medium (eg. the subsequent analogue stages). pvadbx;146005 Wrote: > As I understand it, the error correction for Red Book audio is > distributed, but only nearby, and is nowhere near the quality of ECC > data level error correction in Yellow Book CD-ROM data discs The error correction on CDs is cross-interleaved Reed-Solomon code, and it's actually *more* sophisticated than ECC used in some (more expensive) computer RAM. Both red book and yellow book use the same CIRC strategy; the difference is that yellow book uses more of each block for redundant error correcting data. This is because, while the odd uncorrectable error on an audio CD can be interpolated, on a data CD it's utterly fatal. (And hence the reason why on a 80min blank CDR you can store 700MB when written in data format, but 800MB when written in audio format). -- cliveb Performers -> dozens of mixers and effects -> clipped/hypercompressed mastering -> you think a few extra ps of jitter matters? ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=28621 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
