Wearable Spatial Audio Mixing for Multi-User Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spatial audio systems face challenges in creating a shared and synchronized audio experience for multiple users with their own wearable spatial audio output devices, due to differences in output devices and user physiology, leading to inconsistencies and non-uniform acoustic environments.
Innovation Solution
A wearable spatial audio device that adjusts a device-specific spatialized audio mix based on environmental conditions and user preferences, using sensors to track positions and generate user-specific audio tracks synchronized with dynamic audio objects, allowing for a shared and synchronized audio experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If device-specific spatialized audio mixes are generated for each user, then audio personalization is improved, but audio synchronization and consistency across multiple users deteriorates
Solution Approach 1:
The system dynamically adjusts spatial audio parameters (HRTF characteristics, spatialization settings) based on real-time environmental conditions and user positions. By continuously modifying these parameters, the system maintains both personalization through device-specific profiles and synchronization through environmental adaptation, resolving the contradiction between customized audio experience and consistent multi-user synchronization
2Adaptability or versatility
If environmental conditions are continuously monitored and audio mixes are adjusted, then audio adaptability is improved, but system complexity and processing requirements worsen
Solution Approach 1:
The system implements dynamic audio mixing that automatically adapts to changing environmental conditions such as acoustic reflections, background noise levels, and user positions. The audio mix is continuously adjusted based on real-time sensor data without requiring manual intervention, enabling the system to handle complexity through automated dynamic response rather than static pre-configured settings
Data Source
AI summary
A wearable spatial audio device is provided. The wearable spatial audio device includes one or more audio speakers, one or more processors, and a storage machine holding instructions executable by the one or more processors. Map data is obtained for a real-world environment that includes one or more dynamic audio objects. A device-specific subset of audio tracks is obtained, and a device-specific spatialized audio mix of the device-specific subset of audio tracks that is based on the map data is obtained. An indication of a change in an environmental condition relative to one or more of the dynamic audio objects is received. The device-specific spatialized audio mix is adjusted based on the change in the environmental condition.
