8 bits is 48 dB. Each bit is 6 dB, times 8 gives 48. Now 6 is just an approximation, the real value is 6.020599913 but that is close enough to six for us friends. Humans have a hard time noticing a sound that is 70 dB below another, most recording engineers consider -70 dB to be a total cut. This is how most perceptual lossy compression for audio works. for more, see http://www.pfarrell.com/prc/bits.html -- Pat http://www.pfarrell.com/music/slimserver/slimsoftware.html _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
