[vorbis-dev] noisiness measure?

[Sean R. Lynch]

It seems to me that if you look at the two blocks in the frequency domain,
the one with the solid color will only have a DC component, while the one
with the noise will show the noise spectrum spread throughout.

I would think that what you're really looking for is changes in the
distribution of energy in the frequency domain, which DCT would work fine
for.
