i was wondering "for novelty purposes & future possibilities reasons" for an app to simulate a band playing. for example, three person with the same application link through wifi, and one of them played a high quality music file through this application. what it does it the music sound is divided into three sets/sounds/etc. where one phone plays the guitar only, another plays the drums only, and the third plays the vocal sound only. simulating that there are three phones in a room that each play a different instruments. and if position nicely, you get that surround feel. i guess this this can also applied to games that each player control a certain element/position/function in the game. just wondering about the possiblities of sync.
