Incommensurate is a piece of music composed and performed by Fritz Menzer (using the Chronium app for iOS) that was re-imagined as an interactive 3D Audio experience for headphones. As you move the listener and the individual parts of the piece, every time you listen to it, you will experience it differently. Different automatic movement modes give you a dynamic 3D Audio experience even when the app is running in the background. You can record the binaural audio signal by pressing the record button. Press it again to stop the recording and obtain a AAC encoded M4A file that can be used with music players, smartphones, etc.
