Solution Overview

Problem

Existing audio systems require extensive and time-consuming measurement of control settings to determine responsive behaviors, leading to mechanical wear and inefficiency in capturing the full range of sonic responses across various settings.

Innovation Solution

A robotic system and automated process that uses a neural network to emulate the behavior of a reference audio system by systematically varying control settings, collecting data through a robotic system with electric motors and an audio interface, and utilizing a loss function to improve model accuracy, allowing for a controllable responsive model that can mimic the audio system across different settings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If extensive measurement of control settings is performed to determine responsive behaviors, then measurement precision is improved, but time consumption increases

Engineering Contradiction:
Improvemeasurement precisionVSAvoidtime consumption
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-collecting measurement data for multiple control settings before actual use. The system performs extensive measurements in advance to build a comprehensive database of responsive behaviors, which can then be quickly queried during operation without requiring real-time measurements.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses copying by creating a digital model that replicates the audio system's responsive behaviors. Instead of repeatedly measuring the actual system, the patent creates a virtual copy through neural network modeling that can simulate the system's responses to different control settings, eliminating the need for time-consuming physical measurements.

Inventive Principle:
Principle #26Copying

AI summary

A neural network emulates a behavior of a reference audio system for at least two control settings. A process, for each control setting, receives control position data designating a select control setting of the reference audio system as conditioning for the neural network, communicates an input to the reference audio system and captures a target output, maps parameters of the neural network such that, responsive to the input, a neural output resembles the target output, scores by a loss function, a similarity of the neural network output compared to the target output of the reference audio system, and utilizes the similarity derived from the loss function to modify model parameters of the neural network. A graphical user interface enables a user to select a virtual control setting within the graphical user interface such that the neural network models the reference audio system at the corresponding control setting.
