In Audiosurf the player controls a levitating vehicle similar to those found in Wipeout or F-Zero. The player then maneuvers it down a colorful multi-lane highway, collecting blocks in a manner similar to Klax. The ship is controlled either by a mouse, the arrow keys, the number keys, or a Gamepad (Using XInput drivers such as the Xbox 360 controller, not the older DirectInput drivers). The game also supports the rumble feature of the Xbox 360 controller.
The music used in the game is chosen from the user's own library, from almost any DRM-free format, as well as standard redbook CDs; in addition, Audiosurf includes the entire soundtrack to The Orange Box as part of the download. An "Audiosurf Radio" tab is also included on the "Song Select" screen that allows the user to play the Audiosurf Overture, as well as a shifting selection of songs by featured Independent artists.
