Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound control technologies fail to independently control sound volume and sound quality based on distance from a virtual sound source, leading to a lack of nuanced sound representation in gaming and other applications.
Innovation Solution
A computer-readable storage medium with a sound processing program that uses different references for calculating sound volume and sound quality, allowing for independent control of these parameters in a virtual space, enabling more precise sound representation by adjusting sound volume and quality based on distance from virtual sound sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the same reference is used for calculating both sound volume and sound quality, then the processing is simple, but the sound expression cannot independently control attention points
Solution Approach 1:
The patent segments the sound processing into two independent calculation systems: one for sound volume using a first reference and another for sound quality using a second reference. This allows each parameter to be controlled independently while maintaining manageable processing complexity through modular design.
Solution Approach 2:
The patent applies different reference points (first reference for volume, second reference for quality) to different aspects of sound processing. This local differentiation enables precise control over where players pay attention, allowing sound quality to be optimized at specific locations independent of overall volume levels.
2Measurement precision
If different references are used for sound volume and sound quality, then independent control is achieved, but the system complexity increases
Solution Approach 1:
The patent divides the reference management into separate, dedicated references: a first reference point for volume calculations and a second reference point for quality calculations. This segmentation reduces the complexity of managing multiple parameters by giving each its own dedicated reference.
Solution Approach 2:
The patent changes the parameter control approach by allowing different reference points for different sound parameters. This enables precise control over sound representation by adjusting volume and quality independently through their respective reference frames.
3Ease of operation
If sound volume and sound quality are controlled together, then the processing is straightforward, but nuanced sound expression is lost
Solution Approach 1:
The patent segments sound processing into independent volume and quality control systems, each with its own reference point. This maintains operational simplicity through clear separation while enabling nuanced sound expression through independent adjustment of each parameter.
Solution Approach 2:
The patent applies local quality control by using different reference points for different sound aspects. This allows straightforward processing of each parameter independently while achieving versatile sound expression through the combination of controlled volume and quality at different spatial references.

AI summary
An exemplary embodiment includes: disposing at least one virtual sound source in a virtual space; calculating a parameter relevant to a sound volume on the basis of a distance from a first reference in the virtual space to the virtual sound source; calculating a parameter relevant to a sound quality on the basis of a distance from a second reference in the virtual space to the virtual sound source, the second reference being different from the first reference; and outputting, with a sound volume based on the parameter relevant to the sound volume and a sound quality based on the parameter relevant to the sound quality, a sound associated with the virtual sound source.
