Audio Signal Processor Virtual Switch Assignment Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing audio systems, it is difficult for users to verify if an appropriate audio file is assigned to the immediate output switch before actual operation, and issues arise when inappropriate or damaged files are assigned, leading to unintended output issues.
Innovation Solution
An audio signal processor is connected to the audio apparatus, displaying a virtual switch corresponding to the operation switch, which allows users to check the assignment status through a drag-and-drop operation, judging the normalcy of the assignment and displaying the result, including states of normal, abnormal, and no assignment, using changes in display color and brightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If audio files are assigned to immediate output switches through drag-and-drop operation, then assignment flexibility is improved, but verification of proper assignment before operation becomes difficult
Solution Approach 1:
The system performs preliminary verification of audio file assignments by checking file validity and compatibility immediately when files are dragged and dropped onto virtual switches, before the actual immediate output operation occurs. This preliminary action prevents erroneous files from being assigned and notifies users of assignment status in advance.
Solution Approach 2:
The system provides visual feedback through color-coded indicators on virtual switches to show assignment status (normal, abnormal, or no assignment). This feedback mechanism allows users to immediately verify whether an audio file has been properly assigned without needing to perform additional verification steps.
2Productivity
If audio files are assigned in advance to immediate output switches, then output readiness is improved, but unintended output from damaged or inappropriate files occurs
Solution Approach 1:
The system performs preliminary validation of audio files during the assignment phase, checking whether files are damaged, corrupted, or incompatible with the immediate output function. This preliminary check ensures that only valid audio files are assigned, maintaining output readiness while preventing unreliable assignments.
Solution Approach 2:
The system takes preliminary anti-action by blocking the assignment of inappropriate or damaged files to immediate output switches. Through file validation and error detection mechanisms, the system prevents erroneous files from being assigned in the first place, thereby avoiding potential output failures before they can occur.
3Reliability
If assignment verification is performed before operation, then output reliability is improved, but system complexity increases
Solution Approach 1:
The system performs self-service verification by automatically checking audio file validity and assignment status without requiring user intervention. The verification process is integrated into the existing drag-and-drop assignment mechanism, using the computer's own processing capabilities to validate files and provide feedback, thereby avoiding additional external verification devices.
Solution Approach 2:
The verification function is merged with the existing virtual switch and drag-and-drop assignment interface. The same display unit that shows virtual switches also displays assignment status indicators, and the processor that handles assignment operations also performs verification. This merging avoids adding separate verification hardware or interfaces, keeping the system relatively simple while enabling reliable verification.

AI summary
An apparatus in which a user can easily check that an appropriate audio file is assigned to an immediate output switch. A system includes a PC connected to a communication line, and an audio interface apparatus connected to the PC and having an immediate output switch that outputs, in response to a user operation and to the PC, a reproduction start instruction signal of an audio file which is assigned in advance. The PC judges whether or not the assignment is normal when an audio file is assigned by a user operation, and displays a judgment result in association with a virtual switch displayed on a display corresponding to the immediate output switch.
