A system is presented for generation of output sounds having psychoacoustic qualities comparable to input sound or sounds. Short term and intermediate term features are computed for each input sound, sound components are clustered, filtered, and scored; and a prediction learning system is trained on the probabilities of classes of regions over time. A decoder can make use of this information to generate outputs that sound similar to, but not the same as, the input sound or sounds. The method and apparatus can be operated with no special training.
