nx_aec_q15.nx

nx_aec.nx -- sovereign ACOUSTIC ECHO CANCELLATION (the echoCancellation feature Zoom/Discord/Meet have): the mic picks up the near-end speaker PLUS an echo of the far-end audio coming out of the speakers; AEC learns the echo path with an adaptive NLMS filter over the far-end REFERENCE signal and subtracts the predicted echo, so the other side hears your voice without their own voice bouncing back. Pure Nishi DSP (the browser only ferries raw PCM). w[] = filter taps in Q15 (persist across calls, start zeroed). license_tier: ORIGINAL
