Acoustic Echo Cancellation

Question

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.

I am not sure if WebRTC- and Speex-AEC only cancel the echo of another speaker.

Answer 1

I'm not trying your situation, but in my case, i use the WebRTC-AECM module to deal with the echo things, and I did a loop back test on one android phone, it works good with no echos, but has lots of self-excitation when finishing speaking. hope i helped.
