Hi,
I have a question for some audio professionals out there.
What is the smallest sensible gain control step in dB.
Is it 0.5dB ?
I am asking, because if one is using a digital gain control in a 24bit
fixed point DSP, once could use almost any step size, so I am looking
for the smallest sensible size to use.
Well, the minimum possible difference for 24bit is between -2^23+1 and
-2^23, and that would be about 0.000001dB.
