Abstract
A novel method for tonality estimation and frequency tracking of tonal components modulated in frequency and amplitude is presented. The algorithm detects the local maxima of magnitude spectra corresponding to three contiguous frames of a signal and matches them into the tonal track candidates. The magnitude-based and phase-based methods are used to estimate the frequency jumps between spectrum maxima belonging to the tonal track candidates. Verification of the candidate tonality is based on the distance between frequency jumps derived from the magnitude-based and phase-based estimators. The effectiveness of the proposed algorithm is compared with selected existing methods for tonality estimation used in psychoacoustic models.
