Abstract
Official abstract text for this publication.
The perception of 3D sound positioning can be achieved using a 2D arrangement of speakers positioned around the listener. The disclosed techniques can enable listeners to perceive sounds as coming from above and/or below them, without the need for positioning speakers above and/or below the listener. In some embodiments, elevation information can be included in the X and Y horizontal components of the 2D ambisonics encoding. The X and Y components can be decoded using 2D ambisonics decoding. Suitable filtering may be performed on the decoded sound information to enhance the listener's perception of the elevation information encoded in the X and Y components.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of processing sound information representing a position of a sound relative to an x-axis, a y-axis perpendicular to the x-axis, and a z-axis perpendicular to the x-axis and the y-axis, the method comprising: using a decoder for receiving X encoding information representing a position component of the sound along the x-axis, wherein the X encoding information includes information related to a position of the sound along the z-axis; using the decode…
