Abstract :
In order to estimate the fundamental frequency (fO) of pseudoperiodical sounds with a wide band of possible fO, a theoretical model based on a maximum likelihood for fO is proposed. The model is simplified to make it fast enough for extensive tests. The resulting algorithm is tested on musical speech sounds. As a musical application, an instrument follower based on the algorithm and operating in real time is implemented
