about

nx_rvq_gate.nx -- proves Residual VQ (nx_rvq): greedily train a 3-stage RVQ stack on LPC reflection vectors, then show the reconstruction distortion DROPS with each added stage (the rate-distortion knob), reaching far below single-stage VQ. This is the SoundStream/Lyra codec structure; the neural net replaces the fixed centroids with learned ones.
