about
nx_voice_v2_gate.nx -- proves the NishiVoice v2 q/bit path end-to-end: real LPC residual + entropy coding + inverse
synthesis (what nx_voice_codec.nx says is "the v2 path"). Chain: autocorr -> levinson (LPC coeffs a[1..p] Q30) ->
analysis filter e[n]=s[n]+Sum a[k]s[n-k] -> quantise -> nx_resid_entropy range-code -> decode -> nx_lpc_synth
s[n]=e[n]-Sum a[k]s[n-k]. All on the x86_64 LPC lineage (one syscalls module). MEASURES the entropy compression of
the residual + the reconstruction fidelity. The entropy lever itself was already proven (nx_resid_entropy_gate -46%).
