Dynamic Audio Parameter Adjustment by Object Size
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio technologies fail to dynamically adjust audio parameters based on the size of application objects, leading to a lack of realism in audio rendering in both 2D and XR environments.
Innovation Solution
Implementing system-level rules that adjust audio parameters such as dynamic range, directivity pattern, frequency response, sound power, and reverberation based on the size of objects representing applications, allowing for realistic audio rendering that mimics real-world acoustic behaviors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio parameters are rendered without dynamic adjustment based on object size, then the audio rendering is simple and consistent, but the realism and plausibility of audio rendering deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of audio parameters based on the size of application objects. The system continuously monitors object size changes and automatically adjusts audio parameters in real-time, transforming the static audio rendering into a dynamic system that adapts to changing conditions, thereby improving realism without requiring complex manual intervention
Solution Approach 2:
The patent changes multiple audio parameters (volume, pitch, timbre, spatial position) based on object size variations. By linking parameter changes to object size, the system achieves realistic audio rendering where smaller objects produce quieter, higher-pitched sounds with different timbral characteristics, while larger objects produce louder, lower-pitched sounds with richer harmonics
2Reliability
If audio parameters are dynamically adjusted based on object size, then the plausibility and realism of audio rendering is improved, but the computational complexity and processing requirements increase
Solution Approach 1:
The patent applies different audio parameter adjustments based on the local characteristic of object size. Each application object receives tailored audio parameter modifications according to its specific size, rather than applying a uniform adjustment to all objects. This localized approach optimizes computational resources by focusing processing on individual objects with varying size characteristics
Solution Approach 2:
The system applies partial adjustment of audio parameters based on the degree of size change. Not all parameters are adjusted to the full extent for every object size variation, but rather proportional adjustments are made. This partial action approach reduces unnecessary computational overhead while maintaining the perceived realism of audio rendering
3Stability of the object's composition
If system level rules are enforced for adjusting audio parameters based on object size, then the consistency of audio rendering across multiple applications is improved, but the flexibility of individual application audio control is reduced
Solution Approach 1:
The patent implements a universal audio parameter adjustment mechanism that operates across multiple applications through the operating system. The same size-based adjustment rules are applied consistently to different applications, ensuring uniformity and stability in audio rendering behavior across the entire system, while the underlying audio content and base parameters remain application-specific
Data Source
AI summary
An object can represent computer applications that play audio. Audio parameters associated with the audio can be determined based on size of the object so that when the object is large, the audio sounds like it originates from a large sound source or sources. When the object is small, the audio parameters are determined so that the audio sounds like it originates from a small sound source. Other aspects are described.
