Audio Signal Processing Device Mixing Bus Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional audio signal processing devices face challenges in providing simultaneous monitoring of audio signals at multiple points due to the high cost of multiple cue buses, which is insufficient for requirements in actual use scenarios such as live music concerts or concert halls where multiple engineers need to monitor different sounds.
Innovation Solution
The method involves controlling an audio signal processing device with multiple mixing buses, allowing switching between modes to utilize existing mixing buses as additional cue buses, enabling the selection of transmission destinations for audio signals based on cue controls, and allowing remote control of these settings to efficiently manage signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dedicated cue bus is provided for producing audio signal for monitoring, then the cue function is achieved, but providing a plurality of cue buses increases cost
Solution Approach 1:
The mixing bus is designed to perform dual functions: it can operate as a normal mixing bus for audio signal mixing and as a cue bus for monitoring when a switch is activated. This multi-functionality eliminates the need for separate dedicated cue buses, thereby reducing system cost while maintaining monitoring capabilities.
Solution Approach 2:
The mixing bus is made dynamically switchable between different operational modes (normal mixing mode and cue mode) through a switch component. This dynamic reconfiguration allows the same physical bus to adapt its function based on operational requirements, enabling multiple monitoring points without additional hardware.
2Adaptability or versatility
If a plurality of cue buses are provided to enable simultaneous monitoring at multiple points, then monitoring versatility is improved, but cost increases
Solution Approach 1:
Multiple mixing buses are configured to serve dual purposes: normal audio mixing operations and cue monitoring. By activating switches on specific mixing buses, the system can provide multiple simultaneous monitoring points using the same hardware infrastructure, eliminating the need for separate dedicated cue buses for each monitoring point.
Solution Approach 2:
The patent merges the functions of mixing buses and cue buses into a single integrated system. The mixing bus incorporates both mixing functionality and cue monitoring capability through the switch mechanism, combining what were traditionally separate dedicated systems into one unified multi-functional unit.

AI summary
In an audio signal processing device including a plurality of mixing buses to mix audio signals processed in a plurality of channels, a switching instruction to switch function of the mixing buses is accepted. In accordance with the switching instruction, operation mode of one or a plurality of switch mixing buses among the plurality of mixing buses is switched between a first mode and a second mode. In first mode, the audio signal processing device controls ON/OFF of signal transmission from each of the channels to the switch mixing bus in accordance with settings of ON/OFF of signal transmission from the each channel to the switch mixing bus, and in second mode, the audio signal processing device controls ON/OFF of signal transmission from each of the channels to the switch mixing bus in accordance with manipulation of cue controls respectively provided to correspond to any of the channels.
