It probably should have been called "average_noise". It may
not the best quantity to use since as you point out it will
allow a large distortion in one band if all the other bands have
noise < masking. But thats why we have all those other
variables: tot_noise, over_noise, max_noise and over.
This comes back to the questio of what is the best measure of quality?
the average noise (tot_noise), the average of the noise > masking
(over_noise), the maximum noise in any sfb (max_noise) or the number
of sfb's with distortion (over)? Or some complicated combination
(like the later -X options)?
