Problem

Current audio processing methods for splitting audio files, such as in karaoke and music listening systems, are inefficient and lack intelligence, requiring manual processing and failing to meet user demands for automated sectioning of audio files.

Innovation Solution

A method that constructs relevance characteristic sequences based on similarity, time intervals, or peak values within audio files to determine optimal section breaking points, allowing for automated division of audio files into sections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual processing is used to split audio files, then the processing can be completed, but the efficiency is low and cannot meet user demands

Engineering Contradiction:
Improveaudio file processing efficiencyVSAvoidtime consumed in manual sectioning
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The audio processing system performs automated sectioning by itself without human intervention. The computer executes algorithms to automatically identify section breaking points, extract features, and divide audio files into sections based on musical structure analysis, eliminating the need for manual processing

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical processing with computer-based automated processing. Instead of human operators manually identifying and marking section breaks, the system uses computational algorithms to analyze audio features, detect structural patterns, and automatically determine section dividing points

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Extent of automation

If manual processing is used for audio sectioning, then the task can be completed, but the intelligence of audio processing is low

Engineering Contradiction:
Improveautomation level of audio sectioningVSAvoidcomplexity of processing system
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent segments the audio processing task into distinct computational stages: feature extraction, section breaking point detection, and audio file division. By breaking down the complex automated processing into manageable modules, the system achieves high automation while keeping each component relatively simple and well-defined

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system analyzes multiple audio parameters including amplitude, frequency, and temporal features to identify section breaking points. By monitoring changes in these parameters and their relationships, the automated system can intelligently detect structural boundaries in the audio without requiring complex manual judgment

Inventive Principle:
Principle #35Parameter changes
