Is there a standard way of converting a 24bit sample
to 16bit?
I ask because I think that in different scenarios, one would want a
different result.
1) scale a 24bit value to a 16bit by simple multiplication by a fraction.
2) bit shift the 24bit value, so that the "most useful 16bits" are
returned to the user. The problem here is what are the "most useful
16bits"? I have one application where just using the lower 16bits of the
24bit value is ideal, due to extremely low input signals.
Isn't this what dithering algorithms do for you?
