Audio Signal Processing Apparatus Channel Strip Parameter Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional audio mixers have insufficient operability due to the dispersed placement of user interfaces for adjusting parameters related to effecter units, leading to inferior control efficiency when using multi-function controls for auxiliary signal processing.
Innovation Solution
An audio signal processing apparatus that assigns at least one parameter related to an auxiliary signal processor to manual controls on channel strips, allowing users to adjust these parameters intuitively and efficiently, enhancing operability by consolidating control elements within a single channel strip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If parameters related to the auxiliary signal processor are adjusted using dispersed user interfaces at various locations on the operation panel, then the device can provide comprehensive control functionality, but the operability and control efficiency deteriorate
Solution Approach 1:
The patent consolidates multiple dispersed user interfaces for adjusting auxiliary signal processor parameters into a single integrated channel strip. Specifically, the selection key, encoder, and fader that were previously located at different positions on the operation panel are merged into one channel strip, allowing users to adjust all related parameters (send level, return level, and effecter parameters) at a single location, thereby improving operability without increasing device complexity
Solution Approach 2:
The channel strip is designed to perform multiple functions: it serves as both a conventional channel control interface and an integrated control panel for auxiliary signal processor parameters. The multi-functional channel strip can adjust send level, return level, and various effecter parameters (such as cutoff frequency, resonance, attack, decay) through its components, making it a universal control interface that eliminates the need for separate dispersed controls
2Productivity
If multiple user interfaces are distributed across different locations on the operation panel, then comprehensive parameter control is achieved, but the time required for parameter adjustment increases
Solution Approach 1:
By merging the selection key, encoder, and fader into a single channel strip, the patent enables users to adjust all auxiliary signal processor parameters (send level, return level, and effecter parameters) at one location without moving between different parts of the operation panel, thereby reducing the time required for parameter adjustment and improving control efficiency
Solution Approach 2:
The channel strip is pre-configured with all necessary controls for auxiliary signal processor parameters in their optimal positions. The selection key can directly select different parameters (send level, return level, cutoff frequency, resonance, attack, decay) and the corresponding encoder and fader are immediately available for adjustment, eliminating the need for users to search for controls or navigate through multiple interfaces, thus reducing adjustment time

AI summary
An audio signal processing apparatus comprises: a plurality of channels each configured to perform signal processing on an input audio signal; an auxiliary signal processor (e.g., an effecter circuitry) that inputs an audio signal from one or more of the plurality of channels and performs auxiliary signal processing (e.g., effecter impartment processing) on the input audio signal; a plurality of channel strips each associated with one of the plurality of channels and including a plurality of manual controls for adjusting signal processing parameters of the one channel associated with the channel strip; and a controller that, in response to an assignment instruction given by a user, assigns at least one parameter related to the auxiliary signal processor (e.g., the effecter circuitry) to at least one of the plurality of manual controls included in at least one of the plurality of channel strips.
