title: webrtc AEC algorithm
body: <p>I have made a software that uses WebRTC DSP libraries (AEC, NS, AGC, VAD). Now I need to know what algorithm uses each one to write my Master´s Thesis, but I don't find any information about that.</p>
  
  <p>Someone knows the algorithms of this libraries, specially the Acoustic Echo Cancellation (like for example NLMS, that I know it's commonly used, but I don't know if WebRTC also uses it).</p>
  
  <p>I've tryed to know the algorithm looking into the source code, but I don't understand enough.</p>
  
  <p>Thanks in advance!</p>
