Use the AudioTrack.write() method to write music data out to a stream. You can choose the encoding, sample rate, channels, etc. when you create the AudioTrack object. If you are just sending the data over a serial connection you should be able to do whatever you want. If you are sending audio to a headset, it has to be mono, 8000 bps, PCM modulated.

most probably it will be in PCM or PWN at the receiving end i.e Micro controller, connect DAC amplify analog signal it should work.
