That is one application of dithering, but it is not the definition
of dithering. Dithering is the addition of a noise signal to
improve the statistical properties of sample conversions.
Okay, I goofed up. We were discussing bit depth conversion, and I
dived off into re-sampling.
I agree that bit depth conversion should use dithering (unlike
re-sampling, which does not), but what does this have to do with the
original subject -- why to use 16 bits instead of 8?
If you do work in 8 bits that cause the value range to be compressed,
then later expand the range, you WILL have gaps in the histogram. I
would expect this, and would call any software that dithered in such
cases "buggy."
