Multi-Channel Audio Volume Control with Master-Linked Channel Types
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing and controlling the volume associated with multiple audio sources in audio systems is difficult due to the lack of a systematic approach to adjust channel volumes based on master volume changes and channel type.
Innovation Solution
A computer-implemented method and system that adjusts a master volume and determines channel volumes for each audio channel based on its type, allowing for relative, fixed, or follow main volume configurations, enabling dynamic and systematic volume management across multiple channels using a common interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a master volume control is used to control volume associated with multiple sources, then volume control is simplified, but managing individual channel volumes becomes difficult
Solution Approach 1:
The system segments volume control into two levels: master volume control for overall volume management and individual channel volume controls for specific audio channels. This allows the master volume to simplify overall control while individual channel settings provide the necessary adaptability for different audio sources and types.
Solution Approach 2:
The system dynamically adjusts channel volumes based on the master volume setting and channel volume type. When master volume changes, channel volumes are automatically adjusted according to their configured type (proportional, fixed, or independent), providing both simplicity and adaptability through dynamic behavior.
2Adaptability or versatility
If individual channel volume controls are provided for multiple sources, then channel volume management is improved, but system complexity increases
Solution Approach 1:
The system merges master volume control with individual channel volume controls into a unified control architecture. The master volume setting serves as a baseline that automatically influences all channels, reducing the number of independent controls needed while maintaining individual channel adaptability through volume types.
Solution Approach 2:
The master volume control serves multiple functions: it controls overall system volume, provides a baseline for individual channel volumes, and can independently adjust all channels when needed. This multi-functionality reduces the need for separate controls for each channel in all situations.
3Stability of the object's composition
If channel volumes are adjusted proportionally with master volume, then volume consistency is improved, but flexibility in maintaining fixed channel volumes is reduced
Solution Approach 1:
The system applies different volume adjustment qualities to different channels based on their configured volume type. Some channels are configured for proportional adjustment to maintain volume consistency, while others are configured for fixed adjustment to maintain specific volume levels, allowing each channel to have the appropriate local quality for its purpose.
Solution Approach 2:
The system changes the behavior parameter of channel volumes based on their configured type. When master volume changes, the system applies different adjustment parameters to different channels: proportional adjustment for channels requiring consistency and zero adjustment for channels requiring fixed volumes, providing both consistency and flexibility through parameter variation.

AI summary
A system includes a plurality of sources configured to provide a plurality of audio channels, and a control system including a processor, and a computer-readable storage media having computer-executable instructions embodied thereon. When executed by the processor, the computer-executable instructions cause the processor to adjust a master volume, identify a channel volume type associated with a first audio channel of the plurality of audio channels, and determine a channel volume associated with the first audio channel based at least partially on at least one of the adjustment of the master volume and the channel volume type.
