IP Introduction

Gowin AEC(Acoustic Echo Cancellation) IP is used to remove the echo from the captured signal. This IP can judge whether the captured signal contains echoes by XCORR, and use NLMS(Normalized Least Mean Square) adaptive filter to filter out the echo part with high correlation in the captured signal to realize echo cancellation.

 

Features

  • Supports 16-bit fixed point input
  • Supports configurable filter length
  • Supports threshold and smoothing coefficient configuration for double-talk detection
