Audio Processing Apparatus Mode Switching for Volume Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio processing techniques require complex operations for users to adjust volume parameters for multiple audio signals, either leading to complicated individual adjustments or difficulty in fine-tuning when parameters are linked.
Innovation Solution
A computer-implemented method and apparatus that allows for the adjustment and mixing of audio signals using separate parameters, with two operation modes: one for individual control of each parameter and another for linking them, simplifying the operation by using a single operation to control both the send levels for each audio signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a volume adjustment parameter for each of the plurality of audio signals is individually adjusted, then fine-tuning capability is improved, but operation complexity increases
Solution Approach 1:
The patent implements dynamic switching between two operation modes: individual adjustment mode and linked adjustment mode. The system adapts its behavior based on the selected mode, allowing users to switch between fine-grained individual control and simplified linked control. This dynamic adaptability resolves the contradiction by providing both fine-tuning capability and ease of operation at different times based on user needs.
Solution Approach 2:
The patent changes the control parameters' linkage state based on the operation mode. In individual adjustment mode, each parameter is independently controllable for fine-tuning. In linked adjustment mode, parameters are linked together to simplify operation. This parameter state change allows the system to resolve the contradiction between fine-tuning precision and operational simplicity.
2Ease of operation
If a parameter for each of the plurality of audio signals is linked to other parameters, then operation simplicity is improved, but fine-tuning capability deteriorates
Solution Approach 1:
The system dynamically switches between linked adjustment mode (for operational simplicity) and individual adjustment mode (for fine-tuning capability). This dynamic mode switching allows the system to provide both benefits at different times, resolving the contradiction between operation simplicity and fine-tuning capability.
Solution Approach 2:
The patent segments the control functionality into two distinct operation modes with different parameter linkage characteristics. By dividing the control system into individual adjustment mode and linked adjustment mode, users can select the appropriate segmentation level based on their current needs, thus resolving the contradiction between operational simplicity and fine-tuning precision.
3Measurement precision
If multiple operable elements are provided for controlling multiple parameters, then individual control precision is improved, but device complexity increases
Solution Approach 1:
The patent makes the operable elements universal by enabling them to function in different modes. The same operable element can control parameters individually in individual adjustment mode or control multiple parameters together in linked adjustment mode. This multi-functionality reduces the need for separate dedicated controls for each parameter, thereby reducing device complexity while maintaining individual control precision when needed.
Solution Approach 2:
The operable elements dynamically change their control scope based on the selected operation mode. In individual adjustment mode, each operable element controls a single parameter with high precision. In linked adjustment mode, the same operable elements control multiple parameters simultaneously, reducing the effective number of controls needed. This dynamic adaptability resolves the contradiction between individual control precision and device complexity.
