BITSTREAM REPRESENTING AUDIO IN AN ENVIRONMENT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18636361 titled 'BITSTREAM REPRESENTING AUDIO IN AN ENVIRONMENT
The patent application describes an encoding apparatus that generates metadata for audio data representing audio sources in an environment, including acoustic environment data that describes properties affecting sound propagation for the audio sources. The metadata is applicable to multiple listening poses and includes both static and dynamic properties. The apparatus also generates a bitstream that includes the metadata and audio data for the audio elements in the environment, which can be decoded and rendered by a decoding apparatus.
- Metadata generator generates metadata for audio data representing audio sources in an environment
- Metadata includes acoustic environment data describing properties affecting sound propagation
- Acoustic environment data is applicable to multiple listening poses and includes static and dynamic properties
- Bitstream generator includes metadata and audio data for the audio elements in the environment
- Decoding apparatus can receive and render audio based on the metadata and audio data
Potential Applications: - Virtual reality and augmented reality audio experiences - Immersive audio for gaming and entertainment - Audio processing for spatial audio applications
Problems Solved: - Enhancing the realism and immersion of audio experiences - Providing accurate sound propagation in virtual environments - Improving the quality of audio rendering in complex acoustic environments

Commercial Applications: Title: "Enhancing Immersive Audio Experiences with Advanced Encoding Technology" This technology can be used in virtual reality headsets, gaming consoles, audio software applications, and entertainment systems to provide users with a more realistic and immersive audio experience. The market implications include increased demand for high-quality audio products and services that offer enhanced spatial audio capabilities.
Questions about the technology: 1. How does the encoding apparatus handle dynamic properties in the acoustic environment data? 2. What are the potential limitations of using this technology in real-world applications?
Original Abstract Submitted
An (encoding) apparatus comprises a metadata generator () generating metadata for audio data for a plurality of audio elements representing audio sources in an environment. The metadata comprises acoustic environment data for the environment where the acoustic environment data describes properties affecting sound propagation for the audio sources in the environment. At least some of the acoustic environment data is applicable to a plurality of listening poses in the environment and the properties include both static and dynamic properties. A bitstream generator () generates the bitstream to include the metadata and often also audio data representing the audio elements for the audio sources in the environment. A decoding apparatus may comprise a receiver for receiving the bitstream and a renderer for rendering audio for the audio environment based on the acoustic environment data and on audio data for the audio elements.
