Hey @sangavi-iderize, could you explain a bit more about what you mean by "Not able to update the codes, also not able to access the methods"? We need more information to be able to help out there.

To override both the input and output audio rate, create an audio device module and give it to the PeerConnectionFactory here:

peerConnectionFactory =
                PeerConnectionFactory.builder()
                        .setVideoDecoderFactory(new DefaultVideoDecoderFactory(rootEglBase.getEglBaseContext()))
                        .setVideoEncoderFactory(new DefaultVideoEncoderFactory(rootEglBase.getEglBaseContext(), ENABLE_INTEL_VP8_ENCODER, ENABLE_H264_HIGH_PROFILE))
                        .setAudioDeviceModule(JavaAudioDeviceModule.builder(getApplicationContext())
                                .setSampleRate(16000)
                                .createAudioDeviceModule())
                        .createPeerConnectionFactory();
