Abstract :
The goal of this paper is to present an overview of problems related to features of musical signals based on time-frequency distributions. We recall some aspects concerning extraction of the information from time-frequency representations as Friedman distribution and by using orthogonality and singular value decomposition. For robust identification system (singing voice) a more complete characterization of the analyzed signal is needed. Experimental results are also provided.
