BITSTREAM REPRESENTING AUDIO IN AN ENVIRONMENT - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240267693 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. The metadata includes acoustic environment data describing properties affecting sound propagation for the audio sources, applicable to multiple listening poses and including static and dynamic properties. The apparatus also generates a bitstream containing the metadata and audio data for the audio elements, which can be decoded by a receiver and rendered by a renderer for audio playback based on the acoustic environment data.
- Metadata generator creates metadata for audio data representing audio sources in an environment
- Metadata includes acoustic environment data describing properties affecting sound propagation
- Properties affect multiple listening poses and include static and dynamic properties
- Bitstream generator includes metadata and audio data for the audio elements
- Decoding apparatus can receive and render audio based on the metadata and audio data
Potential Applications: - Immersive audio experiences in virtual reality environments - Enhanced audio playback in gaming and entertainment systems - Spatial audio rendering for movies and music production
Problems Solved: - Optimizing sound quality based on the acoustic properties of the environment - Providing a more realistic and immersive audio experience for users - Simplifying the encoding and decoding process for audio data
Benefits: - Improved audio quality and spatial awareness - Enhanced user experience in various audio applications - Efficient encoding and decoding of audio data for different environments
Commercial Applications: Title: Advanced Spatial Audio Encoding Technology for Immersive Experiences This technology can be used in virtual reality systems, gaming consoles, home entertainment systems, and audio production studios to create realistic and immersive audio experiences. The market implications include increased demand for high-quality audio solutions in various industries.
Prior Art: Researchers in the field of spatial audio encoding have explored similar techniques for enhancing audio playback in different environments. Studies on acoustic properties and sound propagation have influenced the development of this technology.
Frequently Updated Research: Ongoing research focuses on optimizing the encoding and decoding process for spatial audio data, improving the accuracy of acoustic environment modeling, and enhancing the user experience in virtual reality and gaming applications.
Questions about Spatial Audio Encoding Technology: 1. How does this technology improve the spatial awareness of audio playback? This technology enhances spatial awareness by incorporating acoustic environment data into the audio rendering process, creating a more realistic and immersive listening experience.
2. What are the key differences between static and dynamic properties in the acoustic environment data? Static properties refer to fixed characteristics of the environment, such as room size and shape, while dynamic properties include factors like moving objects or changing sound reflections that affect sound propagation.
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.
