MULTI-CHIRP SIGNAL SEPARATION

B. Dugnol, C. Fernández, G. Galiano, J. Velasco

Abstract

Assuming that an specific audio signal, such as recordings of animal sounds, may be modelled as an addition of nonlinear chirps, we use the quadratic energy distribution corresponding to the Chirplet Transform of the signal to produce estimates of the corresponding instantaneous frequencies, chirp-rates and amplitudes at each instant of the recording and design an algorithm for tracking and separating the chirp components of the signal. We demonstrate the accuracy of our algorithm applying it to some synthetic and field recorded signals.
