...the whole 11-22 kHz band with around 1000 bits/s per channel (maybe even 500 bps). Now, I don't know what is the normal bit-rate allocated for this band, but I expect it is greater than that. Am I right? (can anyone give me numbers for this?) The technique I use to do this is inspired from an acticle I published recently (http://panoramix.dyndns.org/jm/scw2000.pdf) and is based on the fact that at these frequencies, the ear is totally insensitive to the spectral fine structure. The processing also has relativly low complexity (most of it is two LPC analysis in the encoder and one in the decode...
