A model for multi-pitch analysis is extended into an iterative multi-pitch analysis and prediction (IMPAP) scheme. The method is efficient in finding harmonic complex tones, such as voiced speech signals, in a mixture of such signals and possible noise background. It can also be used to separate the signal into perceptually relevant speech components. The method may be used in applications ranging from speech transmission (enhancement) to recognition (noise and extra sound rejection).
