RENDERING OF IMMERSIVE AUDIO CONTENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240305952 titled 'RENDERING OF IMMERSIVE AUDIO CONTENT

The present document discusses methods and apparatus for rendering input audio for playback in a playback environment, including audio objects and associated metadata indicating the location of the audio object.

• Creating two additional audio objects associated with the original audio object, evenly spaced on opposite sides of the original location when seen from the listener's position.
• Determining weight factors for the original audio object and the two additional audio objects.
• Rendering the audio objects to speaker feeds based on the determined weight factors.

Potential Applications: - Enhanced audio playback experiences in theaters or concert venues. - Virtual reality and augmented reality applications for immersive soundscapes.

Problems Solved: - Providing a more spatially accurate and immersive audio experience for listeners. - Enhancing the realism and depth of audio playback in various environments.

Benefits: - Improved spatial audio rendering for a more immersive experience. - Enhanced audio localization and separation for clearer sound quality.

Commercial Applications: - This technology could be utilized in the entertainment industry for enhanced audio experiences in theaters, concert venues, and virtual reality applications.

Prior Art: - Researchers in the field of spatial audio and immersive sound technologies may have explored similar methods for rendering audio objects in a playback environment.

Frequently Updated Research: - Stay updated on advancements in spatial audio rendering techniques and immersive sound technologies for potential improvements in audio playback experiences.

Questions about the Technology: 1. How does this technology improve the spatial accuracy of audio playback? 2. What are the potential applications of this technology in virtual reality environments?

Original Abstract Submitted

the present document relates to methods and apparatus for rendering input audio for playback in a playback environment. the input audio includes at least one audio object and associated metadata, and the associated metadata indicates at least a location of the audio object. a method for rendering input audio including divergence metadata for playback in a playback environment comprises creating two additional audio objects associated with the audio object such that respective locations of the two additional audio objects are evenly spaced from the location of the audio object, on opposite sides of the location of the audio object when seen from an intended listener's position in the playback environment, determining respective weight factors for application to the audio object and the two additional audio objects, and rendering the audio object and the two additional audio objects to one or more speaker feeds in accordance with the determined weight factors.
