In this paper we present an original modelling of the source separa­ tion problem that takes into account all the non­stationarities of the underlying processes. The estimation of the sources then reduces to that of a filtering/fixed­lag smoothing algorithm, for which we propose an efficient numerical solution, relying on particle filter techniques.
