Customized Spatial Audio Rendering via Object Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current content providing systems only offer pre-mixed audio content, limiting user experience to a predetermined configuration without the ability to customize spatial audio features, which restricts the immersive 'being-there' experience.
Innovation Solution
A computer system generates audio files and metadata based on spatial features for objects at a venue, using a production tool to create user-customized audio content that recreates the spatial audio experience, allowing users to feel as if they are directly listening to audio signals from specific objects at a specific venue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-mixed audio content is provided for simple playback, then device complexity is reduced and ease of operation is improved, but adaptability and user customization capability deteriorate
Solution Approach 1:
The audio content is segmented into individual audio files for each object at the venue, with separate metadata containing spatial features. This allows the system to provide simple playback of pre-processed content while enabling users to customize and render only the objects they are interested in, thus maintaining ease of operation while improving adaptability.
Solution Approach 2:
Spatial features and metadata are pre-calculated and stored for each audio object during content creation. This preliminary action enables users to perform customization and rendering operations without complex real-time processing, maintaining ease of operation while providing advanced adaptability for user-specific audio experiences.
2Adaptability or versatility
If spatial features are set for each object to enable user-customized being-there, then adaptability and immersive experience are improved, but device complexity and processing requirements increase
Solution Approach 1:
Instead of implementing complex real-time spatial audio processing, the system creates simplified copies of spatial information in the form of metadata that describes the spatial features of each audio object. This metadata can be easily stored, transmitted, and processed, reducing device complexity while maintaining the adaptability for user-customized being-there experiences.
3Adaptability or versatility
If individual audio files are generated for multiple objects with spatial metadata, then adaptability and customization are improved, but data quantity and processing load increase
Solution Approach 1:
The spatial information is extracted from the audio content and stored separately as metadata. This separation allows the audio data to be compressed and efficiently stored, while the relatively small amount of metadata provides the necessary spatial information for customization. This reduces the overall data quantity while maintaining adaptability for generating user-specific audio experiences.

AI summary
Provided are a computer system for producing audio content for realizing a user-customized being-there and a method thereof. The computer system may be configured to generate audio files based on respective audio signals that are respectively generated from a plurality of objects at a venue, set spatial features at the venue for the objects, respectively, using a production tool, and generate metadata for the audio files based on the spatial features. An electronic device may realize a being-there at the venue by rendering the audio files based on the spatial features in the metadata. That is, a user of the electronic device may feel a user-customized being-there as if the user directly listens to audio signals generated from corresponding objects at a venue in which the objects are provided.
