Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital score file production is inefficient due to manual processes, resulting in high costs and low productivity.
Innovation Solution
A method and apparatus that automatically generate digital score files by processing cappella audio files to extract music note information, including onset time, duration, and note value, and combining this data into a digital score file.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual processes are used to produce digital score files, then quality inspection can be performed, but production efficiency is low and costs are high
Solution Approach 1:
The system automatically extracts note information from audio files and generates digital score files without requiring manual quality inspection, making the system self-sufficient and eliminating the need for human operators to verify each file
Solution Approach 2:
The patent replaces manual mechanical processes with automated computer-based processing, using algorithms to extract musical note information from audio signals and generate digital score files automatically, thereby eliminating manual labor while maintaining quality standards
2Reliability
If manual processes are used to produce digital score files, then quality can be inspected, but production time is excessive
Solution Approach 1:
The automated system processes audio files continuously without interruption, extracting note information and generating digital score files in an uninterrupted workflow, eliminating the time losses associated with manual handling and inspection between stages
3Productivity
If automated processing is implemented, then production efficiency is improved, but complexity of the system increases
Solution Approach 1:
The system is designed to handle multiple types of audio files and generate different formats of digital score files using a single automated processing framework, reducing the need for separate specialized systems for each file type or format
Data Source
AI summary
A method and an information processing apparatus to generate a digital score file of a song are described. The information processing apparatus includes processing circuitry. The processing circuitry is configured to obtain a candidate audio file satisfying a first condition from audio files of unaccompanied singing of the song without instrumental accompaniment. The processing circuitry is configured to divide the candidate audio file into valid audio segments based on timing information of the song, and extract pieces of music note information from the valid audio segments. Each of the pieces of music note information includes at least one data set of a music note in the song. The data set includes an onset time, a duration, and a music note value of the music note. The processing circuitry is configured to generate the digital score file based on the pieces of music note information.
