Solution Overview

Problem

Existing sound signal processing technologies fail to effectively reflect the characteristics of one sound in another sound, limiting the ability to generate new sounds with desired emotional or impression-based qualities.

Innovation Solution

A sound signal processing system that utilizes recurrence plot information, specifically UpperRP, to generate a sound signal where the characteristics of a first sound are reflected in a second sound, using a microcomputer and storage to process and output the desired sound signal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional sound signal processing techniques are used, then the processing can be performed with existing methods, but the ability to reflect characteristics of one sound in another sound is insufficient

Engineering Contradiction:

Improveability to reflect sound characteristicsVSAvoidprocessing complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces recurrence plot information as an intermediary representation that captures the characteristic structure of sounds. This intermediary form enables the transfer of characteristics between different sounds by serving as a bridge: the recurrence plot of a first sound is used to modify a second sound, achieving characteristic reflection without direct complex processing between the original sounds.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent copies the characteristic structure from a first sound to a second sound through recurrence plot information. Instead of directly copying the original sound waveform, the system extracts characteristic patterns into recurrence plot form, then applies these patterns to generate a new sound that reflects the desired characteristics while maintaining processing efficiency.

Inventive Principle:

Principle #26Copying

2Manufacturing precision

If detailed sound characteristic processing is performed, then the quality of sound generation is improved, but the data requirements and processing complexity increase

Engineering Contradiction:

Improvesound generation qualityVSAvoiddata requirements

Core Design Contradiction:

Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential characteristic information from sounds in the form of recurrence plots, rather than processing entire sound waveforms. This extraction approach isolates the key structural patterns that define sound characteristics, enabling high-quality sound generation with reduced data requirements by focusing only on the most important feature representations.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A sound signal processing system includes: a first obtainer that obtains recurrence plot information indicating a characteristic of a first sound; a second obtainer that obtains a sound signal of a second sound different from the first sound; a generator that generates a sound signal in which the characteristic of the first sound is reflected in the sound signal of the second sound, based on the recurrence plot information obtained by the first obtainer, the sound signal of the second sound being obtained by the second obtainer; and an outputter that outputs the sound signal generated.
