Abstract / Description of output

We introduce an algorithm implementation for the decomposition of quasi-steady state audio signals using harmonic matching pursuits. Specifically, we propose an initial low-resolution pitch analysis followed by a high resolution harmonic grain extraction based on local complex interpolation within the spectral domain. We describe the implementation of the algorithm and illustrate its applications to musical analysis of monophonic signals before finally discussing possible improvements that could lead to the design of an iterative multi-pitch harmonic analysis system.
