A time-frequency model for pitch analysis

In this paper we present a method for determining the perceived pitch of complex signals. The proposed system is loosely based upon mechanical and electrical models of components within the mammalian auditory system. The notion of scale is emphasized in order to demonstrate the advantages of a wideband time-frequency approach. The system response is then compared with the perceived pitch observed in classic psychoacoustic tests. Data derived from missing fundamental and pulse repetition experiments are presented. Finally, we present promising results when the model is applied to musical sounds and real speech under adverse conditions
