The conclusion of those discussions was that the issue of "resolution" in digital volume controls is a misunderstanding and basically a myth. When you lower the volume digitally you lose in signal/noise, because the noise stays fixed (at least roughly) while the signal decreases. That's it. The errors introduced by digital volume rounding are in the least significant bit of 24 (since the SB3 etc. use 24 bit arithmetic), and therefore are 144 dB down and far below the level of noise already present in the recording and playback system, not to mention human perception. So I suppose if you start with a system and a recording for which the S/N is very large (at max volume), in some vague sense you have more to lose when you lower the volume. But since you started off better, what's the problem? The resulting S/N ratio will always be as good or better than it would have been in a 16 bit version of the same recording, for example. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=52971 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
