Patent ID: 8437485

Claim:
A method for sound field reproduction from a first audio input signal using a plurality of loudspeakers aiming at synthesizing a sound field within a preferred listening area in which none of the loudspeakers are located, said sound field being described as emanating from a virtual source, said method comprising steps of calculating positioning filter coefficients using virtual source description data and loudspeaker description data according to a sound field reproduction technique which is derived from a surface integral, and applying positioning filter coefficients to filter the first audio input signal to form second audio input signals, said method further including the steps of: defining a loudspeaker ranking by means of loudspeaker ranking data representing the importance of each loudspeaker for the synthesis of the sound field within the preferred listening area; modifying the second audio input signals according to the loudspeaker ranking data to form third audio input signals; and alimenting loudspeakers with the third audio input signals for synthesizing a sound field.
