Methods are proposed for separation of harmonic sound sources using sinusoidal modeling. A local nonlinear least-squares (NLS) frequency estimator is proposed to resolve sinusoids that are close in frequency. An iterative analysis scheme using interpolated parameter trajectories and subtraction of detected components is presented. A measure is proposed for testing the accuracy of the model.
