Using the fibonacci sequence to time-stretch recorded music

Human creativity in the music production process is often augmented by technological tools that modify existing musical input, thereby generating unanticipated ideas. The Fibonacci stretch algorithm is a means of time-stretching a music recording, using the Fibonacci sequence as a theoretical basis, such that the resulting music recording is perceived as being in a new meter. Because the overall impulse shape of the recording remains intact, Fibonacci stretch generates novel rhythmic ideas rooted in a natural-sounding transformation of existing musical material. This paper explores the possibilities for Fibonacci stretch to assist in the music production process, and also introduces an audio plugin prototype that encompasses a real-time variant of the algorithm.
