Spatial Audio Object Transmission for Immersive Venue Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current audio content transmission technologies do not allow for user-customized immersive experiences, as they primarily deliver pre-mixed audio signals without considering spatial features of objects at a venue, limiting the ability to recreate the exact audio environment.
Innovation Solution
A computer system detects audio files and metadata with spatial features for objects at a venue and transmits them as an immersive audio track, enabling electronic devices to render user-customized audio content, simulating the experience of listening to audio signals from specific objects at a specific venue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If pre-mixed audio content is transmitted for simple playback, then transmission complexity is reduced, but spatial immersion and customization capability are lost
Solution Approach 1:
The audio content is segmented into individual object audio signals rather than pre-mixed stereo content. Each object's audio is transmitted separately with associated spatial metadata, allowing the receiving device to reconstruct customized spatial arrangements. This segmentation enables both simplified transmission of individual channels and flexible runtime reconfiguration for spatial immersion.
Solution Approach 2:
The system transitions from traditional 2D stereo audio to 3D spatial audio by adding spatial dimension information through metadata. The metadata includes spatial features such as position, distance, and orientation of audio objects, enabling the receiving device to render audio in a three-dimensional space and create immersive spatial experiences.
2Adaptability or versatility
If individual object audio files with spatial metadata are transmitted, then user customization and spatial rendering capability are improved, but data transmission volume and processing complexity increase
Solution Approach 1:
The system merges audio data and spatial metadata into a unified transmission format. The metadata is tightly coupled with corresponding audio objects, allowing efficient packaging and transmission. This combination reduces overall data volume compared to transmitting separate high-resolution spatial data while maintaining full customization capability through the integrated metadata.
3Adaptability or versatility
If individual object audio files with spatial metadata are transmitted, then user customization and spatial rendering capability are improved, but system processing complexity increases
Solution Approach 1:
The system employs automated processes for audio object identification, spatial parameter extraction, and metadata generation. The transmission and rendering systems automatically match audio objects with their spatial metadata and perform runtime reconfiguration without manual intervention. This self-service automation reduces the perceived processing complexity for users while maintaining advanced customization capabilities.

AI summary
Provided are a computer system for transmitting audio content to realize a user-customized being-there and a method thereof. The computer system may be configured to detect audio files that are generated for a plurality of objects at a venue, respectively, and metadata including spatial features that are set for the objects at the venue, respectively, and to transmit the audio files and the metadata for a user. An electronic device of the user may realize a being-there at the venue by rendering the audio files based on the spatial features in the metadata. That is, the user 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.
