Audio Signal Balance and Correlation Display on Single Scale
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for displaying balance and correlation information between audio channel signals, such as stereo or surround signals, do not effectively convey the intended sonic impression, limiting the ability to judge balance and correlation accurately.
Innovation Solution
A method and apparatus that display balance and correlation information of at least a pair of first and second channel signals on a single normalized scale, with a balance indicator and a correlation range indicator, where the correlation range indicator's width exceeds the scale length and is folded back, displayed in contrast color, to represent the sonic impression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If balance and correlation information are displayed using existing separate display methods, then the information can be shown, but the intended sonic impression cannot be accurately judged
Solution Approach 1:
The patent combines balance information and correlation information into a single integrated display element. The balance indicator and correlation range indicator are merged into one visual representation that simultaneously conveys both parameters, allowing accurate judgment of sonic impression without information loss.
Solution Approach 2:
The patent uses color coding to represent different aspects of balance and correlation information. The correlation range indicator uses color variations to indicate correlation values, enabling intuitive visual assessment of the sonic impression while preserving all necessary information.
2Loss of information
If multiple separate indicators are used to display balance and correlation information, then comprehensive information is provided, but the display becomes complex and less intuitive
Solution Approach 1:
The patent merges multiple indicators (balance indicator and correlation range indicator) into a single integrated display element. This consolidation maintains comprehensive information while significantly reducing display complexity and improving intuitiveness.
Solution Approach 2:
The single display element serves multiple functions by simultaneously representing balance information through the balance indicator and correlation information through the correlation range indicator. This multi-functionality eliminates the need for separate indicators while preserving all necessary information.
3Ease of operation
If balance and correlation information are displayed on separate scales, then each parameter is clearly visible, but the overall sonic impression judgment requires more time and effort
Solution Approach 1:
By merging balance and correlation displays into a single scale, the patent enables simultaneous assessment of both parameters in one glance. This eliminates the need to switch between separate scales, significantly reducing the time and effort required for sonic impression judgment.
Solution Approach 2:
The patent transforms the display representation by changing from separate scale parameters to a unified scale parameter system. This allows both balance and correlation to be evaluated concurrently on a single normalized scale, improving operational ease and reducing assessment time.
