Ok. I thought about saying 32, but I didn't want to look absurd. :)
32 bits is absurd. If it works, it would do an excellent job of
digitizing the noise of the input buffer amp.
The good part is that the noise would get mixed away though.
Internally you would have to use 32-bit floating point values,
Why? If you are going to have over 16 bits of output, 64 bit integer
math would be just as good and it would be faster. With 16 bit output,
32 bit integer should be sufficient.
I hadn't thought of going 64-bit yet, but floating point values would
fix the subtle errors introduced by integer mixing.
everything else will be obsolete rather soon. 24-bit D/A conversion
would be nice and 32-bit D/A converters would be great.
Note that 32 bit float is NOT 32 significant bits.
I know, but it would add the possibility to amply the result (digitally).
Or forget about an internal D/A converter all together and use digital
output only.
But where is the DAC? Would it have a good enough filter?
At best in the playback device, being it the TV-set, CD-player or
whatever. So it's up to the end user to determine the overall quality.
