Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current techniques for analyzing audio signals lack an efficient method for users to easily confirm and modify reference data during the generation process, particularly in systems that synchronize human performances with automatic music piece reproduction.
Innovation Solution
An audio processing system that analyzes audio signals from a sound source, identifies sound indicators and pitches, and displays them along a common time axis, allowing users to visualize and adjust the analysis results through a user-friendly interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If reference data is generated through automated analysis of audio signals, then processing efficiency is improved, but user ability to confirm and modify analysis results is worsened
Solution Approach 1:
The system displays analysis results (sound indicators and pitches) on a screen to provide visual feedback to the user. This allows users to confirm the automated analysis results and make necessary modifications, resolving the contradiction between automated processing efficiency and user control capability.
Solution Approach 2:
The display screen acts as an intermediary between the automated analysis process and the user. It presents the analysis results in a visual format that enables users to review and modify the data, bridging the gap between automated processing and user interaction.
2Measurement precision
If multiple analysis parameters are displayed separately, then analysis precision is improved, but user comprehension and operation difficulty increases
Solution Approach 1:
The system merges sound indicators and pitch information into a single unified display view with a common time axis. This integration allows users to comprehend multiple analysis parameters simultaneously without increasing operational complexity, resolving the contradiction between analysis precision and ease of use.
Solution Approach 2:
The system uses a time axis dimension to organize and display multiple analysis parameters (sound indicators and pitches) along the same temporal framework. This dimensional approach allows precise presentation of multiple parameters without increasing interface complexity.
Data Source
AI summary
An audio processing system includes at least one memory storing a program and at least one processor. The processor implements the program to analyze an audio signal including sound from a first sound source; identify, based on the analysis of the audio signal, a series of sound indicators each representing a certainty that audio components of the first sound source are included in the audio signal; identify a series of pitches, each relating to the components of the first sound source; and cause a display device to display the series of the sound indicators and the identified series of the pitches along a common time axis.
