Acoustic Source Separation
A method of separating a mixture of acoustic signals from a plurality of sources comprises: providing pressure signals indicative of time- varying acoustic pressure in the mixture; defining a series of time windows; and for each time window: a) providing from the pressure signals a series of sample values of measured directional pressure gradient; b) identifying different frequency components of the pressure signals c) for each frequency component defining an associated direction; and d) from the frequency components and their associated directions generating a separated signal for one of the sources.
