Abstract
A method and apparatus for processing sound data acquired by a plurality of microphones. The method includes: on the basis of the signals acquired by the plurality of microphones, determining a direction of arrival of a sound originating from at least one sound source of interest; applying spatial filtering to the sound data as a function of the direction of arrival of the sound; estimating ratios, in the time-frequency domain, in a magnitude representative of a signal amplitude, between the filtered sound data on the one hand and the acquired sound data on the other hand; and as a function of the estimated ratios, producing a weight mask to be applied in the time-frequency domain to the acquired sound data in order to construct an acoustic signal representing the sound originating from the source of interest but enhanced relative to the ambient noise.
