Microphone feedback sound too loud on some device.

[affifymirza]

Has anyone experienced receiver feedback noise? Is this problem fixable? Some of my testing devices function perfectly, while others make too much noise even with same model and build.

AudioParam audioParam = new AudioParam.Builder()
                    .setUsingOpusCodec(true).setSampleRate(16000).setFrameSize(960).setChannelSize(1)
                    .setAudioSource(MediaRecorder.AudioSource.MIC)
                    .build();

        VoicePing.INSTANCE.init(VoicePingService.this, "wss://router-lite.voiceping.info", audioParam);

Hello @affifymirza : Check if these

var nsEnabled = false
var aecEnabled = false
var agcEnabled = false

are enabled on your device.

If enabled, but it still problematic, then you can add some audio processing to do that, which are:

• WebRTC Audio Processing Module (APM)
• RNNoise
• Speex DSP preprocessor

However, we will not add those library yet for now.
