RjDj, a new iPhone application that was released earlier this week, is one of the coolest things I've seen released on the still fledgling platform. Download it now, if only to try it for a few minutes. You can download the full version for $2.99
here, or you can try out the
free version (which only has one 'scene').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.
