This paper deals with the problem of the underdetermined blind separation and tracking of moving sources.  ...  In practical situations, sound sources such as human speakers can move freely and so blind separation algorithms must be designed to track the temporal changes of the impulse responses.  ...  EXPERIMENTAL EVALUATION We evaluated the performance of the present method in terms of the ability to separate moving sources and track their DOAs.  ...
