title: Recording multi-channel audio input in real-time
body: <p>I am trying to perform Time Difference of Arrival in real-time using the PS3 Eye. Since it has a built-in 4 microphone array, I've successfully rearranged the array into a square array and cross-correlated the signals using MATLAB to obtain a relatively accurate TDOA algorithm. However, so far I've been recording the signal, saving the files (4 individual files for each microphone in the array), and then feeding those files into MATLAB to read after-the-fact.</p>
  
  <p>My problem is: MATLAB doesn't recognize the PS3 Eye's microphones separately; it only recognizes it as a whole. So far, Audacity is one of the few programs that actually works well in doing so, but I am inexperienced in using the program and don't know its real-time capabilities. Anyone have suggestions as to how can I can perform real-time signal analysis in this manner? If using something else besides the PS3 Eye would work better, then I am open to suggestions. Thanks.</p>
