Embodiment Construction

[0017] It should be understood that the description of the various examples given below is for the purpose of illustration only and should not be construed as limiting. The examples of division of functional blocks, modules or units shown in the drawings are not to be interpreted as meaning that these functional blocks, modules or units must be realized as physically separate units. Functional blocks, modules or units shown or described may be realized as separate units, circuits, chips, functional elements, modules or circuit elements. One or more functional blocks or units may also be implemented in a common circuit, chip, circuit element or unit.

[0018] exist figure 1 In the diagram 100 of an example speaker array or sound bar 102 according to an embodiment of the present invention is depicted. Speaker array 102 may have two or more speakers, eg, speakers and associated transducers 104 , 106 , 108 , and 110 . The transducers may be two small inner transducers 106 and 1...

Abstract

An approach and device for generation of virtual surround sound with a two-way approach that employs a first order head-related models have been used that resemble interaural time difference localization and inter-aural level difference localization cues in the respective frequency bands while avoiding phantom imaging and excessive coloration.

Description

technical field [0001] The present invention relates to virtual loudspeaker sound systems, and more particularly, to digital signal processing and loudspeaker arrays for rendering rear surround channels. Background technique [0002] Typically, spatial enhancement techniques have been applied to play surround sound using only a few speakers. Currently, spatial enhancement technologies that allow surround sound to be played through several speakers placed in front of the listener are available from many different manufacturers. Examples of such applications include 3D sound reproduction in home theater systems that do not require the installation of rear speakers, and surround rendering of movies and computer games using small integrated transducers in multimedia monitors or laptop computers. Often, the listening experience is less than convincing due to glaring issues such as: (i) a very narrow sweet spot that does not even allow large head movements; (ii) severe picture an...
