XR Audio Parameter Adjustment via Energy Map Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In extended reality systems, discrepancies in parameter settings across audio elements lead to inconsistencies in audio rendering, potentially disorienting users and failing to provide an immersive experience due to variations in gain settings and manufacturing differences among microphones and other audio devices.
Innovation Solution
An XR device determines parameter adjustments by analyzing energy maps from various audio elements, forming a composite energy map to synchronize gain settings and operational status, enabling adjustments to ensure uniform audio capture and rendering across the system.

Engineering Contradiction Analysis
1Manufacturing precision
If parameter settings are adjusted for each audio element to account for manufacturing differences, then audio rendering consistency is improved, but device complexity and processing overhead increase
Solution Approach 1:
The system dynamically adjusts audio parameters (gain, frequency response) for each audio element based on measured energy maps. This allows compensation for manufacturing variations in microphones and audio devices while maintaining consistent audio rendering across all elements, resolving the contradiction between manufacturing precision and parameter adjustment complexity
Solution Approach 2:
The system measures the actual energy maps of audio elements and uses this feedback to automatically determine and apply parameter adjustments. This closed-loop approach ensures audio consistency without requiring manual calibration, reducing the operational complexity despite the sophistication of the adjustment mechanism
2Reliability
If all audio elements are processed and monitored for functional status, then audio quality is improved, but processing resources are consumed
Solution Approach 1:
The system identifies and excludes non-functional audio elements from processing by analyzing their energy maps. By extracting and removing defective elements from the active audio set, the system maintains high audio quality from functional elements while reducing the processing resources required to monitor and adjust all elements
Solution Approach 2:
The system processes audio elements selectively based on their functional status rather than uniformly processing all elements. By applying processing only to functional audio elements identified through energy map analysis, the system achieves high audio quality while optimizing resource consumption by avoiding unnecessary processing of non-functional elements
