Which is irrelevant to the (sub) conversation that you were replying to. Where it was alleged that 24 bit is not needed even for DSP. It is that statement that was being refuted.Agreed, but in mastering you would never be in integer,
(My bold)
Yes but you said we need 24bits to avoid quantization errors becoming audible, and yeah sure it's inaudible at 24 bits since the errors is at -144dB below full scale which no human could ever hear, but then the recording will also most likely have some inherent noise which acts just like dither so the errors won't even be there.
And if you truncate down to 16bit or even lower you ofcourse eliminate the dither making it completely inaudible. But tbh the audibility of quantization errors at 16bit without dither is also probably way below of what humans can hear anyways.
So no you don't need 24bits or even 1 bit to avoid quantization errors, you just need dither![]()
