vacquah Wrote: > Whats the theory in regards to digital volume controls? Many audiophiles seem to think that digital volume controls cannot perform as well as analogue volume controls. They are mistaken, for the following reason:
For sure, as you turn down a digital volume control, you begin to lose resolution: the quantisation noise floor of the DAC will increase. BUT... as you turn down a digital volume control, the replay loudness also reduces (of course), and it does so by the same amount as the increase in quantisation noise. The upshot of this is that the absolute sound pressure level of the quantisation noise remains constant regardless of the setting of the digital volume control. If you can't hear the quantisation noise when the digital volume control is at max, you won't hear it when you turn it down. -- cliveb ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=20222 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
