A send audio to B:

1. record audio at A side: you can create your owned 'audio_device' and record audio frame when it delivered form device.
2. record audio at B side: you can record audio frame at 'AudioReceiver::OnData()'

That's what i've done. But processing it's the thing i'm troubling with.
Can you suggest some way to process it in order to mixer it in to 1 file.
