HEADPHONE RENDERING METADATA-PRESERVING SPATIAL CODING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240334146 titled 'HEADPHONE RENDERING METADATA-PRESERVING SPATIAL CODING
Simplified Explanation: The patent application describes systems and methods for preserving Headphone Rendering Mode (HRM) in object clustering for object-based audio data processing.
- An audio data processing system receives audio objects with spatial position information and HRM metadata.
- It calculates cluster positions and object-to-cluster gains using an extended hybrid distance metric.
- The audio objects are rendered to form clusters, which are then transmitted to a spatial reproduction system.
Key Features and Innovation:
- Preservation of Headphone Rendering Mode (HRM) in object clustering.
- Use of an extended hybrid distance metric for calculating cluster positions and gains.
- Rendering audio objects to form clusters for spatial reproduction.
Potential Applications:
- Spatial audio processing in virtual reality environments.
- Enhanced audio rendering in gaming and entertainment systems.
- Improved sound localization in immersive audio experiences.
Problems Solved:
- Maintaining Headphone Rendering Mode (HRM) in object clustering.
- Efficient calculation of cluster positions and gains for spatial audio reproduction.
Benefits:
- Enhanced spatial audio experience for users.
- Improved accuracy in sound localization.
- Seamless integration of audio objects in clustered environments.
Commercial Applications: Spatial audio processing technology can be utilized in:
- Virtual reality headsets and gaming consoles.
- Entertainment systems and home theaters.
- Audio production and post-production studios.
Prior Art: Readers can explore prior art related to spatial audio processing, object clustering, and Headphone Rendering Mode (HRM) in audio technologies.
Frequently Updated Research: Stay informed about the latest advancements in spatial audio processing, object clustering algorithms, and immersive audio technologies.

Original Abstract Submitted
systems and methods for preserving headphone rendering mode (hrm) in object clustering are described. in an embodiment, an object-based audio data processing system includes a processor configured to receive a plurality of audio objects, wherein an audio object of the plurality of audio objects is associated with respective object metadata that indicates respective spatial position information and an hrm; determine a plurality of cluster positions by applying an extended hybrid distance metric to a spatial coding algorithm to calculate a partial loudness for each of the audio objects; render the audio objects to the cluster positions to form a plurality of clusters by applying the extended hybrid distance metric to the spatial coding algorithm to calculate object-to-cluster gains; and transmit the clusters to a spatial reproduction system.
