Patent ID: 8654990

Claim:
A system for use in filtering of an acoustic signal, the system comprising: a filtration module and a filter generation module comprising a directional analysis module and filter construction module wherein: said filter generation module is configured for receiving at least two input signals corresponding to an acoustic field; said directional analysis module is configured to apply processing to analyze said at least two received input signals for determining directional data including data indicative of the amounts of direct and diffuse sounds in the analyzed signals, the direct and diffuse sounds having, respectively, relatively high correlation and relatively low correlation in the analyzed signals; and said filter construction module is configured to utilize data indicative of predetermined parameters of desired output directional response and of required attenuation of diffuse sound in an output signal for analyzing said directional data, and to generate output data indicative of operative parameters of said filtration module and; said filtration module is configured to filter a certain input signal corresponding to said acoustic field based on said operative parameters and to produce an output acoustic signal corresponding to said desired output directional response and to said required attenuation of diffuse sound.
