title: How do I specify what mData in AudioBuffer in the CoreAudio framework should represent?
body: <p>How do I initialize the CoreAudio framework such that I know what the values in mData represent?  As per a previous reply I had gotten, it seems these values can represent 4 byte floats, 4 byte signed integers etc.  But what API would I use to specify what exactly I want these values to represent?</p>
