You can change the init function like this, here you can overcome the default browser sample rate to 16000 and also the channels indicating the mono/stereo we can change that one also , if it is mono it will be 1 , other wise two .

 function init(config) {
            //sampleRate = config.sampleRate;
            sampleRate = 16000;
            debugger;
            //numChannels = config.numChannels;
            numChannels = 1;
            initBuffers();
        }
