NOTE EVENT MODELING FOR AUDIO MELODY EXTRACTION

This paper outlines a method for the MIREX05 contest “Audio Melody Extraction”. The method aims at extracting the fundamental frequency (F0) trajectory of the predominant melody, such as the lead singing, within polyphonic and multitimbral audio signals. The method is based on a multiple-F0 estimator front-end followed by the probabilistic modeling of note events and their relationships. The performance of the method was ranked second best in the MIREX05 evaluations.
