The application is difficult to describe and on paper it sounds sort of silly (see the video below for a convincing demonstration). Using the iPhone’s built in microphone, the application listens for ambient noise which it then modifies and infuses into an automatically generated dynamic soundtrack. Each of the application’s six different “scenes” has a different feel to it, with options like a trance-like beat that might fit in at a club and a track that is based entirely on percussion. Each track also treats the incoming audio differently - some tracks loop the input, while others distort it.
