Default Noise Shaping for high rez files and streams

In the very start of digital some recordings looked fantastic on specs but
sounded crap, seeming like they had some kind of noise gate on them. then
came dither, which made recordings sound right again. I'll just leave this
hanging there....

I've continued to think about ways to reduce the excess 'sea of noise
bits'
that tend to occuply the least significant bits per sample of 'high rez'
streams and files. These tend to bloat FLACing, etc, so waste space,
money,
time, etc. Occurred to me that Noise Shaping down the sample size whilst
keeping the high sample rate might help. So I did some simple experiments.

If anyone is interested you can see the results at

All being well, I'll put up a tidied version of the demo program as well
in
case any computer programmers want to have a play with it.
