Solution Overview

Problem

Existing acoustic processing systems lack the ability to flexibly and easily distribute audio signal processing across multiple devices, with prior art focusing on synchronization of parameters without considering audio signal processing distribution.

Innovation Solution

An acoustic processing system comprising a first apparatus with a CPU for system control, a second apparatus with a CPU for audio signal processing, and a network for communication using protocols like TCP/IP, allowing control information to be sent between CPUs for distributed audio signal processing, enabling flexible distribution of audio signal processing across devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If audio signal processing is performed on a single apparatus, then the processing can be simplified and controlled locally, but the processing capacity is limited and cannot be easily distributed

Engineering Contradiction:
Improveprocessing capacityVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The audio signal processing system is divided into multiple independent apparatuses (first apparatus for control, second apparatus for audio processing, third apparatus for additional processing). Each apparatus has its own CPU and memory, allowing the processing load to be segmented and distributed across multiple devices, thereby increasing overall processing capacity while maintaining individual device simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A network connection serves as an intermediary between the multiple apparatuses, enabling communication and coordination. The first CPU sends control information to the second CPU through the network, allowing distributed processing without requiring direct physical integration of the apparatuses, thus managing system complexity through standardized communication interfaces.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If parameter synchronization is implemented between multiple apparatuses, then coordinated control is achieved, but the complexity of managing multiple apparatuses increases

Engineering Contradiction:
Improvecoordination reliabilityVSAvoidmanagement complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The parameters stored in the memory of the first apparatus and the second apparatus are synchronized, effectively merging their control spaces. This ensures that parameter changes in one apparatus are reflected in others, achieving coordinated control without requiring complex inter-apparatus synchronization protocols for each individual parameter.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The network communication protocol is designed to handle multiple functions including parameter synchronization, control information transmission, and status monitoring. This universal approach reduces management complexity by consolidating multiple control functions into a single communication framework rather than requiring separate mechanisms for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If audio signal processing is distributed across multiple apparatuses, then processing capacity and flexibility are improved, but the difficulty of controlling and coordinating the apparatuses increases

Engineering Contradiction:
Improveprocessing flexibilityVSAvoidcontrol ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system allows dynamic allocation of audio signal processing tasks across different apparatuses based on current system conditions and requirements. The first CPU can send control information to different second CPUs as needed, enabling flexible adaptation to varying processing demands while maintaining ease of operation through centralized control logic.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The synchronized parameter mechanism provides feedback loops where parameter changes in one apparatus are automatically reflected in others. This feedback mechanism simplifies control by eliminating the need for manual coordination and real-time adjustment, as the system automatically maintains consistency across distributed apparatuses.

Inventive Principle:
Principle #23Feedback

AI summary

An acoustic processing system for audio signal processing includes a first apparatus including a first memory that stores a first parameter for the audio signal processing and a user interface that receives an operation for changing the first parameter, a second apparatus including a second memory that stores a second parameter synchronized with the first parameter and a first CPU that performs system control, and a third apparatus including a second CPU that performs the audio signal processing. The first CPU sends, to the third apparatus, control information for controlling the audio signal processing based on the second parameter, and the second CPU receives the control information, and performs the audio signal processing based on the control information.
