316 * bu applying noisy band depriorization and tonal band priorization.
317 * Maxval-energy ratio gives us an idea of how noisy/tonal the band is.
318 * If maxval^2 ~ energy, then that band is mostly noise, and we can relax
607 /* Try to make sure there is some energy in every nonzero band
625 /* !g is the DC band, it's important, since quantization error here
