A perceptually motivated multiple-F0 estimation method

This paper describes a method for estimating of the fundamental frequencies (FO) of several concurrent musical sounds. The method consists of a computational model of the human auditory periphery, followed by a novel periodicity analysis mechanism. Estimation of multiple fundamental frequencies is achieved by cancelling each detected sound from the mixture and by repeating the estimation for the residual. Computational load of the method remains reasonable since the peripheral hearing model (i.e., the hardest part) needs to be computed only once. The method is relatively straightforward to implement and outperformed two state-of-the-art reference methods in simulations.
