Record 44KHz audio from bluetooth?
<p>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?</p>

<p>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.</p>

<p>I have read <a href="http://stackoverflow.com/questions/4026002/how-to-record-sound-using-bluetooth-headset">How to record sound using bluetooth headset</a> and tried the approach indicated--but cannot get it to work.</p>
