Audio Device Acoustic Separation for Dynamic Rhythm Pattern Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio devices and methods for playing music pieces are limited in their ability to provide new expressions by only separating and processing specific parts of a music piece, lacking flexibility in rhythm pattern changes and improvisation during continuous playback.
Innovation Solution
An audio device and method that acoustically separates a music piece into parts, allowing for parallel playback of sounds at different positions and temporal patterns, with dynamic cross-fading and progression rate control, enabling changes in rhythm patterns without altering the underlying sounds, thereby allowing for new expressions and improvisations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a music piece is separated into parts and only specific parts are processed, then the ability to cut or process specific sounds is improved, but the flexibility for rhythm pattern changes and improvisation is limited
Solution Approach 1:
The music piece is divided into multiple acoustic parts (e.g., vocals, drums, bass, guitars) that can be independently processed. This segmentation allows specific sounds to be selected and manipulated while maintaining the ability to change rhythm patterns through temporal repositioning of these separated parts.
Solution Approach 2:
The system dynamically adjusts the temporal patterns of separated sound parts during playback. By allowing flexible repositioning of drum sounds, bass sounds, and other instrumental parts in real-time, the system enables rhythm pattern changes and improvisation while maintaining continuous playback of the music piece.
2Adaptability or versatility
If rhythm patterns are changed during continuous playback, then new expressions and genre bending are enabled, but the complexity of coordinating multiple temporal patterns increases
Solution Approach 1:
By separating the music piece into distinct acoustic parts, each with its own temporal pattern, the system can independently control and coordinate different rhythm patterns. This segmentation reduces the complexity of coordination by allowing parallel processing of multiple temporal patterns without interfering with each other.
Solution Approach 2:
The system changes temporal parameters (time positioning, rhythm patterns) of specific sound parts independently. By adjusting parameters such as the timing of drum hits, bass notes, or instrumental phrases, the system achieves genre bending and new expressions while managing complexity through parameter-based control rather than structural reconfiguration.
3Adaptability or versatility
If cross-fading is used to transition between temporal patterns, then seamless genre bending is achieved, but the duration of the transition segment increases
Solution Approach 1:
The cross-fade transition uses parameter changes in the temporal patterns of separated sound parts to achieve seamless genre bending. By gradually adjusting timing parameters and rhythm characteristics during the transition segment, the system maintains audio continuity while enabling genre transformations, with the transition duration optimized based on the complexity of the pattern change.

AI summary
There is provided an audio device for playing a music piece, the music piece including a first part and a second part that are acoustically separable from each other, the audio device including: a first playing module configured to play the first part; and a second playing module configured to play, in parallel with playing of the first part, the second part in a first temporal pattern in a first segment of the music piece, and at least one sound included in the second part at a position that is different from a position in the first temporal pattern in a second segment of the music piece.
