I am currently working on a project which involves sending different signals to different wireless headphones (bluetooth) connected to a single computer. Would anyone know how to do this? That is, how to set headphone A to receive signals from channels 1-2, headphone B to receive from channels 3-4, headphone C from channels 5-6, etc. I read somewhere that I need to create a kind of virtual sound device with N channels which is composed out of all these headphones, but I am not sure how to do so.
I am on Linux but I also have the possibility to use OS X for this project. Any ideas?
