Embodiment Construction

[0026] For better understanding, the principles of embodiments of the present invention will now be explained in more detail in the following description with reference to the accompanying drawings. It is to be understood that the present invention is not limited to these exemplary embodiments, and that specified features may also be appropriately combined and / or modified without departing from the scope of the present invention as defined by the appended claims. In the figures, elements of the same or similar type or respectively corresponding parts are provided with the same reference numerals to avoid the need to re-introduce the items.

[0027] figure 1 A simplified flow diagram illustrating the determination of a target sound scene at a target location from two or more source sound scenes is depicted. First information about two or more source sound scenes and target locations is received 10 . Next, two or more spatial representations of the source sound scene are locat...

Abstract

A method, a computer readable storage medium, and an apparatus (20, 30) for determining a target sound scene at a target position from two or more source sound scenes. A positioning unit (23) positions (11) spatial domain representations of the two or more source sound scenes in a virtual scene. These representations are represented by virtual loudspeaker positions. A projecting unit (24) then obtains (12) projected virtual loudspeaker positions of a spatial domain representation of the target sound scene by projecting the virtual loudspeaker positions of the two or more source sound scenes on a circle or a sphere around the target position.

Description

technical field [0001] The solution relates to a method of determining a target sound scene at a target position from two or more source sound scenes. Further, the solution relates to a computer readable storage medium having stored therein instructions enabling determination of a target sound scene at a target location from two or more source sound scenes. Furthermore, the solution relates to a device configured to determine a target sound scene at a target position from two or more source sound scenes. Background technique [0002] 3D sound scenes, such as HOA recordings (HOA: High-Order Ambient Audio), deliver realistic acoustic experiences of 3D sound fields to users of virtual sound applications. However, moving within the HOA representation is a difficult task because small-order HOA representations are only valid in a very small area around a point in space. [0003] For example, consider a user moving from one acoustic scene to another in a virtual reality scene, w...
