Adding 2 channel (stereo) audio delivery to FlyVR about fly-vr

[mwangq]

hardware: a pair of earbuds plugged into the sound card

Example of why we want 2 channel (stereo) audio: the male fly moves around during courtship, so I might want that song to also "move" from left earbud to right earbud (so, one playlist item, with different sound on each earbud). A second example is simply testing for neural responses that come from the left, or from the right (so these would be separate playlist items; maybe even the exact same playlist item, but played only thru one earbud speaker).

I wonder if a good solution is for the user to always provide 2 columns of audio data (left earbud, right earbud). I like your idea of having an optional channel field (channel 1, channel 2, or both).
