The "magic" function just needs to add the sample data, saturating at the +/- limits. pyglet doesn't expose the sample data in a useful format, but if you dig around the media sources you'll see that sample data is generally just a string of bytes or ctypes array. You can achieve the same outcome by playing the two sources simultaneously -- this has the added bonus that pyglet will use hardware audio mixing where possible.
