Title:
METHOD FOR CONTROLLING A SPEAKER ARRAY TO PROVIDE SPATIALIZED, LOCALIZED, AND BINAURAL VIRTUAL SURROUND SOUND
Document Type and Number:
WIPO Patent Application WO/2012/068174
Kind Code:
A3
Abstract:
A system and method for producing a binaural and localized audio signal to a user is provided. A signal processing method is provided for delivering spatialized sound in various ways using highly optimized inverse filters to deliver narrow localized beams of sound from the included speaker array. The inventive method can be used to provide private listening areas in a public space and provide spatialization of source material for a single user to create a virtual surround sound effect. In a binaural mode, a speaker array provides two targeted beams aimed towards the primary user's ears - one discrete beam for the left ear and one discrete beam for the right ear. In a privacy mode, a privacy zone could be created in which a primary audio beam would deliver a signal of interest to the user while secondary beams would be aimed at different angles to provide a masking noise.
