Audio Signal Processing Apparatus Bus Feed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio signal processing systems lack the ability to easily control and differentiate the amount of feed to different buses, making it difficult for users to perform specific audio signal processing tasks such as localization processing for various input channels.
Innovation Solution
An audio signal processing apparatus with multiple buses and a controller that allows users to assign input channels to specific buses and adjust the amount of feed for each channel, using send level adjustment circuits and PAN circuits to perform localization processing on selected channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If each input channel is assigned to a specific bus with independent feed control, then the ability to perform specific audio signal processing tasks (such as localization processing) is improved, but the device complexity increases
Solution Approach 1:
The audio signal processing apparatus divides the audio signal flow into multiple independent buses (first bus, second bus, etc.), each capable of receiving different input channels with independent feed controls. This segmentation allows different processing paths for different channels, enabling specific tasks like localization processing for vocals while keeping other channels simple, thus improving adaptability without requiring complete system complexity.
Solution Approach 2:
Different buses are assigned different functions and processing characteristics. For example, one bus can be optimized for localization processing while another handles general mixing. Each input channel can be selectively assigned to buses with appropriate processing qualities, allowing local optimization of signal processing for specific channels without affecting the entire system.
2Ease of operation
If multiple buses with independent feed control are provided, then the ease of operation for controlling feed amounts is improved, but the device complexity increases
Solution Approach 1:
Multiple buses are provided with similar functional capabilities (feed control, signal routing), allowing the same operational procedures to be applied across different buses. This multi-functionality design enables users to control feed amounts for different channels independently while maintaining consistent operation interfaces, improving ease of operation without proportionally increasing complexity.

AI summary
An audio signal processing apparatus includes a first bus, a second bus, and a controller that assigns a first input channel to the first bus, assigns a second input channel to the second bus, receives an amount of feed from the first input channel to the first bus, and receives an amount of feed from the second input channel to the second bus.
