Audio Device Simulator Individual Model Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Analog audio devices of the same type produce unique sound tones due to their individual characteristics, making it challenging to create an accurate model that replicates the sound of one device from another, even if they are of the same type.
Innovation Solution
An audio device simulation method and system that acquires a standard model for input-output characteristics of an analog audio device, measures specific parameters of a target device, and generates an individual model by correcting the standard model using measured input-output characteristics, allowing for the unique sound of each device to be modeled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a standard model is used for all audio devices of the same type, then the model is simple and easy to manage, but the unique sound characteristics of each individual device cannot be captured
Solution Approach 1:
The invention changes parameters of a standard model by introducing correction values derived from actual measurement data. The standard model is adjusted by applying corrections to specific parameters (e.g., frequency response, distortion characteristics) based on measured differences between the standard model and actual device performance, thereby capturing individual device characteristics without requiring complete redesign of the modeling approach
Solution Approach 2:
The invention creates a corrected model that copies the essential characteristics of actual audio devices by measuring their input-output characteristics and using these measurements to generate correction values. The corrected model replicates the unique sound characteristics of each device by combining the standard model with device-specific correction data, enabling accurate reproduction without physical possession of the device
2Measurement precision
If individual measurement and modeling of each audio device is performed, then the unique sound characteristics can be captured, but the time and resources required increase significantly
Solution Approach 1:
The invention performs preliminary action by establishing a standard model that represents the typical characteristics of audio devices in a category. This standard model serves as a baseline that can be quickly corrected for individual devices without requiring measurement of all possible characteristics from scratch, significantly reducing the time and resources needed for individual device modeling while still capturing unique characteristics
3Measurement precision
If analog audio devices are physically possessed and measured, then accurate individual models can be created, but the physical devices occupy space and require maintenance
Solution Approach 1:
The invention creates digital copies (corrected models) of physical audio devices by measuring their input-output characteristics and encoding these characteristics into model parameters. The corrected models replicate the unique sound characteristics of physical devices without requiring the physical devices to be possessed, maintained, or stored, eliminating the need for physical device infrastructure while maintaining modeling accuracy

AI summary
An audio device simulation method includes acquiring a standard model that models input-output characteristics of an audio device, and setting at least one parameter of a target audio device of the same type as the audio device and measuring input-output characteristics of the target audio device, and generating an individual model that models input-output characteristics of the target audio device by correcting the standard model using measured input-output characteristics that have been measured.
