title: Acoustic Echo Cancellation
body: <p>Does anybody know an AEC for Android that works with just one speaker?
  Let's say I talk into my Android phone which streams the audio data to a PC which outputs these data immediately on speakers. So I will hear my own voice.</p>
  
  <p>I am not sure if WebRTC- and Speex-AEC only cancel the echo of another speaker.</p>
