Music Processing Model Chord Progression Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio processing technologies primarily focus on speech processing and fail to maintain harmonious and consistent musicality in music processing, resulting in less harmonious music before and after processing.
Innovation Solution
A method and apparatus for audio processing that utilize a music processing model to extract chord progression features and audio features from input music data, along with text features from processing instructions, to generate processed music data that maintains consistent chord progression and harmonious musicality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing speech processing technologies are applied to music processing, then processing capability is provided, but musicality consistency and harmony are deteriorated
Solution Approach 1:
The patent changes the parameter focus from general speech processing features to music-specific chord progression features. By extracting and preserving chord progression features (tempo, key, chord sequence) as critical parameters, the system maintains musicality consistency while enabling various music processing operations through the music processing model.
2Adaptability or versatility
If general audio processing is used, then processing flexibility is improved, but chord progression consistency is worsened
Solution Approach 1:
The patent segments the audio processing task into distinct components: chord progression feature extraction, audio feature extraction, and music generation. By separating chord progression analysis from other audio features, the system can independently control and maintain chord progression consistency while allowing flexibility in other processing aspects through text instructions.
Solution Approach 2:
The system extracts chord progression features from the input music, processes the audio according to text instructions, and then generates output music that maintains similarity to the original chord progression features. This feedback loop ensures chord progression consistency is preserved throughout the processing pipeline.
