Assuming I am using an A2DP-compatible bluetooth headset and that the headset is properly

  • 0

Assuming I am using an A2DP-compatible bluetooth headset and that the headset is properly paired and connected, how can I record to an audio file using the bluetooth headset as the source?

In this case, when there isn’t a Bluetooth headset, I record from the microphone to an M4A file containing AAC data with a sample rate of 44100 and a bit rate of 160,000, then proceed to manipulate the audio data–changing the format is not an option.

I have read How to record sound using bluetooth headset and tried the approach indicated–but cannot get it to work.

    http://developer.android.com/reference/android/media/AudioManager.html#startBluetoothSco%28%29, if accurate, indicates that the sampling for audio input streams must be 8kHz… very low audio quality.

    Any examples I have found just show recording raw PCM data to an AudioRecorder, where it can then be turned into a WAV file. Using the MediaRecorder seems right out. As far as I can tell, there is no solution.
