Apparently it's a bit in the S/PDIF stream which, if set, indicates that the sample is invalid. Presumably the DAC would repond by muting the volume (for that sample). I guess that should only happen if neither error correction nor interpolation is possible? > > I believe that CIRC substitutes the correct bit, whereas interpolation > may or may not be the correct bit (and after that we're into > muting/clicking). Yeah - that's right. CD is 16-bit audio, that's about 65,000 possible values, so it's pretty unlikely interpolation will get exactly the correct one (of course it's not randomly picking 1/65000 since it looks at the nearby samples, but still). -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=24957 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
