Streaming audio from microphone in iPhone using Xa

Question

Recording with AudioQueue and Monotouch static sound demonstrates how to get audio via an iPhone's microphone into an AudioQueue using Xamarin.iOS. My question is: how do I keep the microphone continuously recording? I basically want to keep the microphone on for as long as the app is open, and continuously capture the audio stream (note that I do not want to save the stream to file). Inside a long-running while-loop?

This should work: https://github.com/sami1971/SimplyMobile/blob/master/iOS/SimplyMobile.Media/Audio/AudioStream.cs

Initialize and use Start() on application start and then call Stop() when application closes (or goes background). Captured buffers are delivered through event handler OnBroadcast.

EDIT: Here is a quick WaveRecorder class. I have not had time to test it so if you find bugs in it, please push back changes or let me know what needs to be changed. https://github.com/sami1971/SimplyMobile/blob/master/Core/SimplyMobile.Media/Audio/WaveRecorder.cs
