title: Two-channel recording on the iPhone/iPad: headset + built-in mic
body: <p>For an app, we have a requirement to record from two different audio sources. One mic is a special (throat) mic and it comes with the same connector that the iPhone headset with mic uses.</p>
  
  <p>On a second channel, we would like to record the ambient sounds and the best thing would be if we could just record from the iPhone's/iPad's built-in mic at the same time as we record from the throat mic headset.</p>
  
  <p>Is there any way this is possible? Any other tips?</p>
