[dfavaro]

Can we do it?

Please check this file:

• https://github.com/muaz-khan/RecordRTC/blob/master/dev/StereoAudioRecorder.js

It may help you export PCM packets or buffers.

var recorder = RecordRTC(audioStream, {
    recorderType: StereoAudioRecorder
});
recorder.startRecording();

recorder.getInternalRecorder().getLeftRightChannels(function(leftChanenls, rightChannels) {
    // do your own stuff here
});

Now modify StereoAudioRecorder.js to add getLeftRightChannels:

// StereoAudioRecorder.js (add anywhere)
this.getLeftRightChannels = funtion(callback) {
    // return any kind of data
    callback(leftChannel, rightChannel);
};

@muaz-khan I tried above code and it gives error that,
Uncaught TypeError: Recorder is not a constructor
at initRecorder (RecordRTC.js:86)
at Object.startRecording (RecordRTC.js:67)
