Hi Sy,
Ok, dither introduce noise out of audio band and shift digital noise higher.

SY said:Dither is necessary to avoid both amplitude and time quantization error. It converts errors of time and amplitude resolution to errors of noise. For example, if you have an undithered sine wave that drops in amplitude, at a certain point (at the LSB) the sine wave suddenly vanishes. With dither, you hear a little more hiss than before, but you can hear the sine wave even as it drops below the supposed resolution limit of the system- sort of like analog tape.

I never understand why CD are not recorded to 0db, since recording studio works with 24bit resolution?

Like the later recordings here ? Recording levels are more a function of competence than sample rate and wordlength.
