Abstract :
In the paper the possibilities of using instantaneous complex frequency (ICF) for analyzing and modifying simple sounds are discussed. Before estimating ICF, a bifactorization of a signal is applied in order to obtain two factors: one fully characterized by its envelope and the other with positive instantaneous frequency.
