Abstract (en)
[origin: EP0527529A2] A method is described for manipulating an audio equivalent signal through positioning of mutually overlapping time windows. These are displaced with respect to each other over an actual pitch period length, and multiplied by a window function. Systematic repeating, suppressing, and maintaining of segment signals will accommodate the signal to an intended overall length.
