Spatial Audio Rendering with Simplified Sound Object Previews
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current spatial audio technologies do not effectively allow users to comprehend changes in sound scenes without fully rendering the audio content, making it difficult to detect and render new or updated spatial audio content efficiently.
Innovation Solution
An apparatus and method that selects spatial audio content based on a user's position, records consumption data, and provides a user-selectable option to render a simplified sound object representative of the content, enabling detection of new events and rendering of updated audio content through data comparison and preview features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If spatial audio content is fully rendered for user consumption, then the user can comprehend the sound scene, but it becomes difficult to detect and manage changes in the audio content efficiently
Solution Approach 1:
The patent segments the spatial audio content into individual sound objects, each with unique identifiers and characteristics. This segmentation allows the system to track and detect changes in specific sound objects independently, making change detection more efficient while maintaining complete comprehension of the overall sound scene through the collection of all sound objects.
Solution Approach 2:
The patent implements preliminary action by recording consumption data and metadata about spatial audio content before actual rendering occurs. This pre-recording of information enables the system to detect changes and provide summaries without requiring full rendering of the audio content, thus facilitating efficient change detection while preserving the ability to comprehend the sound scene when needed.
2Productivity
If simplified sound objects are rendered as previews, then change detection becomes efficient, but the user experience may be compromised compared to full rendering
Solution Approach 1:
The patent applies partial action by rendering simplified sound objects as previews rather than full audio content. This partial rendering provides sufficient information for change detection and user evaluation in most cases, achieving efficient productivity while maintaining acceptable user experience. The system offers this as an optional preview mode rather than replacing full rendering entirely.
Solution Approach 2:
The patent implements dynamics by making the rendering approach adaptive - the system can switch between simplified previews and full rendering based on user needs and context. This dynamic approach ensures that when users require detailed evaluation, full rendering is available, while for routine change detection, efficient simplified previews are used, thus balancing productivity and reliability.
3Use of energy by moving object
If spatial audio content is selected based on user position, then the rendering is optimized for the user's location, but detecting new events in the audio content becomes more complex
Solution Approach 1:
The patent applies preliminary action by recording consumption data and metadata for all spatial audio content regardless of user position. This pre-recording creates a comprehensive database that facilitates easy detection of new events and changes. The position-based rendering optimization is applied only during the rendering phase, while the detection phase benefits from the pre-recorded data structure.
Solution Approach 2:
The patent segments spatial audio content into individually trackable sound objects with unique identifiers. This segmentation allows the system to efficiently detect new events by comparing identifiers and metadata of individual sound objects against the recorded database, rather than analyzing entire audio streams. The position-based selection then determines which segmented objects are rendered, maintaining both optimization and detectability.

AI summary
An apparatus comprising: means for causing selection of spatial audio content in dependence upon a position of a user in a virtual space; • means for causing rendering, for consumption by the user, of the selected spatial audio content including a first spatial audio content; • means for causing, after user consumption of the first spatial audio content, recording of data relating to the first spatial audio content; • means for using, at a later time, the recorded data to detect a new event relating to the first spatial audio content, the new event comprises that the first spatial audio content has been adapted for which a new spatial content is created, for example in the form of a limited preview; and • means for providing a user-selectable option to enable rendering, for consumption by the user, of the first spatial audio content by rendering a simplified sound object representative, which can be a downmix or clustered audio objects.
