Rather than provide the phase information, how about adding a random dither to the model? Trading noise for aliasing is almost always an improvement.At around 4000 bit/s we could start sending the phases of each harmonic, that would make a significant difference. Currently the phases are discarded, a we use a rule based approach to synthesise them at the decoder. This phase model is the cause of the "buzzy" artefact discussed a week ago by Ed.
