Well actually decibels are defined according to the ratio of the power or amplitude in the signals. Twice the power is about 3dB, twice the amplitude is about 6dB. (This is why 1 bit corresponds to 6dB: when converted to analogue, each bit doubles the output voltage (amplitude)). I'm not sure about the psychoacoustics of perceived volume w.r.t. decibel change, but I seem to recall that twice as loud corresponds to about a 6dB increase - ie. it tracks the amplitude rather than power scale. Whatever, a 10dB increase is certainly going to sound more than twice as loud. rjplummer;150124 Wrote: > I haven't looked at how the volume control in the software works but > -24dB is pretty quiet.Indeed it is. And -48dB is very, very quiet. -- cliveb Performers -> dozens of mixers and effects -> clipped/hypercompressed mastering -> you think a few extra ps of jitter matters? ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=27832 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
