There are two things here:
- Hardware limitations in ADDA chips. These are 8-16-24-32 bit. No floating point. More is better, but at the current 24 bit we are all using, we already have a dynamic range of 144 dB. Far more than what we need, as analog circuitry doesn't surpass 125 dB. For playback, 16 bits (CD format) is already 96 dB dynamic range and more than most, if not all amps and loudspeakers can do.
- Calculations inside the DAW. AFAIK Reaper has always had 64 bit FP internally. And I believe there's at least one DAW out there that boasts 128 bit FP. But I forgot which one, as it is very, very silly. 64 bit FP is already impossible to clip. What would 128 bit FP add, except that it needs a lot more RAM?
