about
nx_vq_dred_gate.nx -- proves the VQ moonshot rung (nx_vq): vector-quantising the LPC reflection envelope to a codebook
index collapses the DRED redundancy bitrate toward the 12-32 kb/s neural target, with bounded distortion. Builds a
codebook from period-varied LPC analyses (the classical stand-in for a trained codebook), VQ-encodes an in-codebook
vector (exact) and a held-out vector (generalisation), and measures bits + distortion + the DRED tail at VQ rates.
