Echo cancellation in Pili #155

Open gouravd opened 8 years ago

gouravd commented 8 years ago

I was testing PLDroidCameraStreaming for 1-1 video chat. User1 live streams and subscribes to User2's live stream and Vice versa.

Everything works fine except there is echo. Can you please implement echo cancellation?

v2.0.0 had been callback the PCM data to caller. You can do it on v2.0.0 if you want.

public interface AudioSourceCallback {
    void onAudioSourceAvailable(ByteBuffer srcBuffer, int size, boolean isEof);
}

Thanks, since this is new, could you please share any kind of documentation or sample code so that I understand what I need to do.

gouravd commented 8 years ago

I am unable to figure out how to achieve this in the new V2. can you please give hints

AudioSourceCallback#onAudioSourceAvailable is the callback of the PCM from the microphone. If you want to do the Echo Cancellation, you should import the Echo Cancellation algorithm for the PCM.
