Abstract

A source separation system (10) processes input signals formed by mixtures of primary signals originating from sources and estimates the primary signals so that the estimates do not differ even in the presence of non-stationary input signals. The system includes a first separation sub-assembly (12) which produces first estimates of the primary signals, a second sub-assembly (14) which adaptively determines the separation coefficients, and a third sub-assembly (15) which standardizes the first estimates and produces first standardized estimates used for the calculation of the separation coefficients. An output module (17) produces estimates which have between them the same proportionality ratio as that existing between the primary signals. A selection module (19) avoids an estimate being duplicated on various outputs in the case where certain primary signals are absent or very weak.
