SpeedPitch is a media art application that functions as a music player. Its unique feature is altering music playback rate and pitch based on your real-time GPS ground speed, creating an augmented sonic reality.

Can I use SpeedPitch with any music file?
SpeedPitch is designed as an experimental sonic reality tool, not a general-purpose media player. Its primary function is to alter playback based on movement, so it's best experienced with this specific purpose in mind.
What is the best way to use SpeedPitch?
