Echo handling #27

Closed prechtelm closed 3 years ago

prechtelm commented 4 years ago

Hi, we experience extreme echoing during calls. How could we handle that problem?

we tried the following without any success: MediaConstraints mediaConstraints = new MediaConstraints(); mediaConstraints.mandatory.add(new MediaConstraints.KeyValuePair("googNoiseSuppression", "true")); mediaConstraints.mandatory.add(new MediaConstraints.KeyValuePair("googEchoCancellation", "true"));

and

WebRtcAudioUtils.setWebRtcBasedAcousticEchoCanceler(true); WebRtcAudioUtils.setWebRtcBasedAutomaticGainControl(true); WebRtcAudioUtils.setWebRtcBasedNoiseSuppressor(true);

Any suggestions?

KVS owns the signaling portion of the webrtc for Android. Perhaps, Googles webrtc forums might have a better answer for issues related to noice suppression.

For your information, some other projects are calling setWebRtcBasedAcousticEchoCanceler(false) on specific phone models. This fixes an echo on calls where the speaker is ON. See: signalapp/Signal-Android#7635
