has some interesting pointers to finding audio sources. There's alot of 
interesting work documented in the neighborhood of that url.

The key seems to be:

1) identify the audio stream you care about,
2) find the video stream containing that individual

in our system with 1 audio and 4 video streams that means either 

1) knowing more about the physical space and the devices, or
2) decoupling things so we can use the audio and video as analytical parts 
to search better.
