In this thesis, Blind Source Separation (BSS) of Convolutive Mixtures of Sources is addressed. For separating audio mixtures, we have developed new methods for cases without noise and with noise in propagation environment. The method for case without noise is based on joint diagonalization of spectral matrices and exploit the non stationarity of signals. We have proposed two techniques in order to solve permutation problem. The second method where an additive noise is present, is based on maximum likelihood. Simulations were done with reel data of acoustics room.Dans cette thèse, la Séparation Aveugle de Mélanges Convolutifs de Sources est étudiée.
