Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard audio content is used without spatial customization, then device complexity is reduced, but audio immersion and realism deteriorate
Solution Approach 1:
The system performs preliminary actions by obtaining spatial information about the user environment and speaker positions before generating the final audio content. This allows the audio rendering engine to pre-calculate spatial audio parameters and optimize the audio signal in advance, achieving immersive spatial audio without adding complex real-time processing requirements during playback.
Solution Approach 2:
The patent introduces an audio rendering engine as an intermediary component that bridges between standard audio content and the final spatially customized audio output. This intermediary processes the audio signal according to spatial information and speaker configurations, enabling complex spatial audio effects while keeping the source audio content and playback devices relatively simple.
2Reliability
If spatially customized audio is generated based on environmental information, then audio realism is improved, but processing time and computational resources increase
Solution Approach 1:
The system obtains spatial information about the environment and speaker positions in advance before audio playback. This preliminary acquisition of spatial data allows the audio rendering engine to pre-compute spatial audio parameters and optimize processing, reducing real-time computational requirements while maintaining high audio realism through spatial customization.
3Manufacturing precision
If audio content is converted based on multiple parameters (metadata, spatial information, speaker specs), then audio customization accuracy is improved, but system complexity increases
Solution Approach 1:
The audio rendering engine serves as a universal platform that handles multiple audio customization parameters including video metadata, audio metadata, spatial information, and speaker specifications through a single integrated system. This multi-functional approach enables comprehensive audio customization without requiring separate processing systems for each parameter type.
Solution Approach 2:
The system achieves precise audio customization by dynamically changing multiple parameters including spatial position, speaker configuration, and audio metadata. These parameter changes are coordinated through the audio rendering engine, which adjusts audio characteristics based on the combination of spatial information and device specifications to achieve accurate spatial audio reproduction.
