If by scale you mean time-scale, you could try to search for "phase
vocoder". There was a nice summary paper on phase vocoders at some DAFX
conference, along with a Matlab code (It was online, but I don't
known if it is still online; try searching for "TRADITIONAL (?)
IMPLEMENTATIONS OF A PHASE-VOCODER: THE TRICKS OF THE TRADE")
