Abstract :
A comparison of two models for processing sound is presented: the perceptually-based pitch model of Meddis and Hewitt (1991), and a vocoder model for rhythmic analysis by Scheirer. Similarities in the methods are noted, and it is demonstrated that the pitch model is also adequate for extracting the tempo of acoustic signals. The implications of this finding for perceptual models and signal processing systems are discussed
