Your understanding is incorrect. In digital volume controls you start with some integer value, multiply it by the volume factor (which is some number less than 1), and round the result to the nearest integer value. You're probably thinking of the errors introduced by that rounding. Since the SB2/3 uses 24 bits for internal calculations, the rounding errors are in the 24th (really, the "25th") bit, which means more than 144dB down from full scale. Errors at that level are totally inaudible under all circumstances. There is a real issue with digital volume control, but it isn't "dropping bits" - it's just that any digital device has some intrinsic noise floor, and lowering the volume decreases the signal while leaving that noise floor unchanged, hence lowering signal/noise. But that's a smooth function of the volume - there's no special value where it becomes a problem. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=53836 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
