I think the point that was being made [and at this point I pause to stress that it is not my point but i am telling you what i think the point is] was that if you isolate the recording of a quiet sound maxing 7 bits above digital noise floor, then this would be the same as a 7 bit recording of this noise alone using the full dynamic range of the 7 bits. You may say that all 16/24 bits represent the quiet noise, but there are only 7 bits worth of possible values representing this quiet noise [I am not quite sure this is the case]. If the quiet noise had been make much louder then it would have had the benefit not only of being at a higher level but having been captured with greater precision. If you assumed that the analog sytem would be able to resove that lw level noise with infinite resolution (on the assumtion that nalog recording works like an optical zoom rather than a digital zoom [provocative or what]) then the analog recording of this sound would be better. -- adamdea ------------------------------------------------------------------------ adamdea's Profile: http://forums.slimdevices.com/member.php?userid=37603 View this thread: http://forums.slimdevices.com/showthread.php?t=82050 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
