What's wrong is this whole "bit perfect" idea. It's true that if one wanted to take the attenuated digital stream and reconstruct the original data, that would be impossible when the volume is reduced by more than a factor of 256 (or even less if the gain factor is such that rounding is necessary). But that's NOT what one wants to do - not at all. You're sending the stream into a DAC, and the DAC converts it into an analogue voltage. The only thing that matters then is the S/N of the resulting analogue stream, and the S/N varies smoothly with the gain factor. There is no sudden change at 256, and there is also no change when there is rounding versus when there isn't. The reason is that the noise level of the DAC is well above the rounding errors. This is not just an opinion - it's a fact which can be proven mathematically and checked empirically (there was a plot of the S/N as a function of volume posted a while back). > This isn't gong to be another of your 'can't hear -144dB' faux pas is > it? Oh please. You were wrong about that, and you're simply not big enough to admit it. That's obvious to anyone reading that thread. You never had any response to the points I (and others) made - you just resorted to childish insults. > It's possible that if you have replay gain tags in your FLAC files they > would sound different to a WAV file (with no tags), converted to FLAC > on the fly. That's a good point. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=46229 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
