摘要：

This paper deals with the auditory scene analysis via application of ICA in a time-frequency domain. An extension of an original algorithm is presented. This extension consists in Bayesian estimation of a number of independent components via direct implementation of selected grouping principles and via analysis of a structure of the previous time-spans. While the original algorithm is not capable to process sound scenes with fluctuating number of independent sound sources, the presented extension can operate also on sound scenes with the fluctuating number of sound sources.
