Much of today's musical signal processing is based upon local decomposition methods, often using short-range, windowed Fourier transforms. Such methods are supposed to mimick some aspects of human hearing. Using global decomposition instead, analyzing the complete source sound in one transform, opens up a new world of interesting sound manipulation methods. These methods are difficult to analyze in terms of human auditive perception or musical intuition but can produce exciting sounds. A program that explores these possibilities has been written and placed in the public domain.
