Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio mixers struggle to easily associate sound volume panning and delay panning settings, leading to reduced service areas and inconsistent sound distribution in large venues, where sound volume panning may not be suitable due to its limitations in covering all audience positions.
Innovation Solution
A sound processing apparatus that automatically interlocks the settings of sound volume panning and delay panning parameters, allowing users to adjust one parameter and have the other parameter change accordingly, ensuring consistent localization settings across different environments without additional time or labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If sound volume panning is used to set localization, then the mixer construction is simple, but the service area decreases and sound signals do not reach all audience positions
Solution Approach 1:
The patent combines sound volume panning and delay panning into a single integrated system. The control device automatically coordinates both panning methods, allowing them to work together rather than separately. This merging enables the system to maintain simple mixer construction while achieving wider service area coverage through the complementary effects of both panning techniques.
Solution Approach 2:
The mixer is designed to perform multiple localization setting functions simultaneously - both sound volume panning and delay panning. The signal processing device can individually perform either or both types of localization setting, making the system versatile and adaptable to different venue requirements while maintaining operational simplicity through automatic control coordination.
2Device complexity
If sound volume panning is used for localization, then the mixer construction is simple, but sound distribution consistency deteriorates in large venues
Solution Approach 1:
The control device automatically adjusts the delay amount based on the sound volume panning settings, creating a feedback mechanism that ensures consistent sound distribution. When sound volume panning is changed, the system automatically coordinates the delay panning to maintain proper sound localization and distribution consistency across the audience area.
Solution Approach 2:
The system performs automatic coordination between sound volume panning and delay panning without requiring manual intervention. The control device automatically changes the delay amount in response to sound volume panning adjustments, enabling the system to self-regulate and maintain consistent sound distribution across different venue configurations.
3Area of stationary object
If delay panning is used to set localization, then the service area increases, but setting coordination between sound volume panning and delay panning becomes difficult
Solution Approach 1:
The control device automatically coordinates the settings between sound volume panning and delay panning without requiring manual intervention. When either parameter is adjusted, the system automatically adjusts the other parameter to maintain proper localization, eliminating the difficulty of manual setting coordination while preserving the wide service area benefits of delay panning.
Solution Approach 2:
The system automatically changes the delay amount parameter in response to sound volume panning parameter changes. This automatic parameter coordination allows the system to maintain optimal localization settings across both panning methods, making operation easy while achieving wide service area coverage through delay panning.
4Manufacturing precision
If manual coordination of sound volume panning and delay panning settings is performed, then setting precision can be maintained, but time and labor requirements increase
Solution Approach 1:
The control device automatically performs the coordination between sound volume panning and delay panning settings, eliminating the need for manual adjustment. The system maintains precise localization settings by automatically calculating and applying the appropriate delay amount based on sound volume panning changes, thereby preserving setting precision while eliminating the time and labor required for manual coordination.
Solution Approach 2:
The system uses automatic feedback control to maintain precise localization settings. When sound volume panning is adjusted, the control device automatically adjusts the delay panning parameters to maintain proper sound localization, ensuring setting precision is maintained without requiring manual intervention or additional time for coordination.

AI summary
A sound processing apparatus includes a signal processing device that individually performs first localization setting (e.g., sound volume panning) for setting localization of an input sound signal based on a value of a first parameter and second localization setting (e.g., delay panning) for setting localization of the input sound signal based on a value of a second parameter. In response to an adjustment by an operation device of the value of one of the first and second parameters, a control device automatically changes the value of the other of the first and second parameters. In this way, sound image localization based on the first localization setting and sound image localization based on the second localization setting are automatically controlled in an interlocked relation to each other. At least one of the sound signals localized based on the first and/or second localization setting is output to an output destination.
