Spatial Audio Rendering - A simplified explanation of the abstract
This abstract first appeared for US patent application 18027728 titled 'Spatial Audio Rendering
Simplified Explanation
The patent application describes a technology that enables spatial audio rendering with six degrees of freedom for a listener's movement.
- Spatial audio refers to sound that is designed to mimic the way we hear in the real world, creating a more immersive experience.
- The technology uses higher order ambisonic signals, which are complex audio signals that capture the full 3D sound field.
- An apparatus is described, which includes circuitry for generating audio signal content sets that create spatial audio scenes.
- The apparatus also determines the positions in which the spatial audio scenes can be heard.
- The technology associates a subset of audio signal content sets with each determined position.
- For example, if there are two positions, a first subset of audio signal content sets is associated with the first position, and a second subset is associated with the second position.
- When audio signal content is provided for rendering, the appropriate subset of audio signal content sets is retrieved based on the listener's position.
- If the listener is at the first position, the first subset of audio signal content sets is retrieved, and if the listener is at the second position, the second subset is retrieved.
- This allows for a more dynamic and personalized spatial audio experience based on the listener's location.
Original Abstract Submitted
Apparatuses, systems, methods, and computer programs enable spatial audio rendering that allows for six degrees of freedom of movement of a listener. The spatial audio comprises higher order ambisonic signals. An apparatus includes circuitry for generating audio signal content sets that provide spatial audio scenes; determining positions in which the spatial audio scenes are audible; and associating a subset of audio signal content sets with the determined positions such that a first subset of audio signal content sets is associated with a first position and a second subset of audio signal content sets is associated with a second position. When audio signal content is provided for rendering, the first subset of audio signal content sets is retrieved if the listener is at the first position and if the listener is at the second position the second subset of audio signal content sets is retrieved.
