Audio Mixer Parameter Restoration via Temporary Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional audio mixers face challenges in accurately and quickly returning parameter values to their original state after temporary adjustments, especially during live performances, due to the inefficiencies and increased processing load associated with the scene function.
Innovation Solution
A setting device with a temporary operation mode that allows users to adjust parameter values manually, storing pre-change values as change history and automatically returning them to the original state upon ending the temporary mode, reducing the need for manual operation and minimizing processing load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the scene function is used to return parameter values to previous states, then parameter restoration accuracy is improved, but processing time increases and processing load increases
Solution Approach 1:
The patent segments the parameter restoration process by creating a dedicated temporary operation mode that handles only the specific parameters that were changed, rather than restoring all parameters as the scene function does. This segmentation allows for faster, more targeted parameter restoration.
Solution Approach 2:
The patent applies partial action by implementing a temporary operation mode that only affects the parameters that were temporarily changed, rather than performing a complete scene restoration. This partial restoration approach reduces processing time and load while maintaining accuracy for the specific parameters that need changing.
2Measurement precision
If the scene function is used to return parameter values to previous states, then parameter restoration accuracy is improved, but device complexity increases
Solution Approach 1:
The patent segments the parameter management system into normal operation mode and temporary operation mode, with the temporary mode handling only transient parameter changes. This segmentation reduces the overall processing load by avoiding unnecessary scene data management for temporary adjustments.
Solution Approach 2:
The patent extracts the temporary parameter adjustment functionality from the overall scene management system, creating a separate temporary operation mode. This extraction reduces device complexity by isolating the temporary adjustment logic from the main scene function processing.
3Ease of operation
If manual operation is used to return parameter values to previous states, then ease of operation is maintained, but operation accuracy decreases and operation time increases
Solution Approach 1:
The patent implements self-service by enabling parameters to automatically return to their previous values when the temporary operation mode is ended. This eliminates the need for manual intervention to restore parameters, combining ease of operation with high restoration accuracy through automated recall of stored parameter values.
4Measurement precision
If the scene function is used for temporary parameter changes during live performance, then parameter restoration accuracy is improved, but reliability decreases due to mixer inoperability and sound signal disruptions
Solution Approach 1:
The patent uses partial action by implementing a temporary operation mode that only restores the specific parameters that were changed, rather than performing a complete scene restoration. This partial restoration approach minimizes processing time and avoids mixer inoperability or sound signal disruptions, thereby maintaining reliability during live performances.
Solution Approach 2:
The patent applies skipping by enabling rapid parameter restoration through the temporary operation mode, which quickly returns parameters to previous values without the delays associated with complete scene restoration. This rapid restoration maintains mixer operational continuity and prevents sound signal disruptions during live performances.

AI summary
A setting device includes: a manual-operator operable by a user for adjusting a parameter value; a mode selector for selecting a temporary operation mode that is a mode for temporarily operating the manual-operator; a memory; and a controller. The controller performs storage control for, in association with an adjusting operation executed via the manual-operator while the temporary operation mode is selected, storing into the memory a pre-change parameter value as a change history and return control for returning the adjusted parameter value of the manual-operator to the pre-change parameter value based on the change history in response to ending of the temporary operation mode. Because only the parameter value adjusted during the temporary operation mode can be returned to the pre-change parameter value, the inventive setting device can easily, quickly, and accurately return the parameter value, temporarily changed during the temporary operation mode, to the pre-change parameter value.
