ABSTRACT
An algorithm for compressing or expanding the duration of an arbitrary sound is presented, in which the frequencies present in the sound are not changed by the process. This means that music can be slowed without changing the key, and that sped up or slowed down voices can still be recognized. The process can be performed in a small fraction of real time, meaning that it can be done live, while the sounds are being captured.
