output to multiple (two) sound devices

[GiudiceLab]

I figured out how to output sound to both headphones and speaker in the same script, and I thought this might be generally useful for people, so I am posting an example script. I hope that's okay--I didn't see any rule against it.

This code uses pySonic (pySonic.sourceforge.net), which is a python wrapper for the Fmod programming library. I used it to create a secondary sound output. This way, I could play sounds to the headphones using the built-in Vizard library, which outputs to the Windows default device, and I could play sounds to the speakers using pySonic's functions.

I haven't tried multiple outputs with spatialized sound, and I haven't tested how well this works with our actual experiment code, but I thought it was a good start. I hope it is useful. Any revelations are appreciated.

Thanks for posting this info and script.
