Hello everyone.
I would like to know if there is way to use pan in Ruby. For who don't know it, pan is the technique to play sounds in a specific audio output side.

Example, play a vocal sound only in the left audio output, and the bass on the right one.

And, PS, I don't wanna to get the pan information of a song, I want to only reproduce a specific sound, on only one of my speakers.

Best Regards, and sorry for the bad english.
