@picofarad i saw fabrice had a neural compressor thingy but i haven't paid much attention to them.

google uses one for phone compression; they have some wavenet to wavenet thing that has a neural compressor output tokens they send over the wire. i think that was remade as LPCNet by xiph, but hasn't gotten much love.

lpcnet does the same over codec2, with the vocoder layers there to reconstruct voice quality that codec2 utterly massacres
