Timed Timbre Control in Music Playback and Instrument Synthesis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack the ability to allow users to set desired timbre controls at specific times during musical piece playback, limiting the flexibility and customization of audio playback and instrument playing experiences.
Innovation Solution
An information processing device that receives inputs for timbre control at specific playback times and transmits audio signals with corresponding timbre control information to a device that synthesizes and outputs the playback sound of a musical piece and the playing sound of a musical instrument, enabling precise audio control including effects like vibrato, tremolo, and reverb.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional music playback systems are used, then basic audio playback is achieved, but timbre control at specific times during playback is not available
Solution Approach 1:
The patent segments the musical piece playback time into discrete time points or time ranges, allowing independent timbre control settings for each segment. This enables precise temporal control of timbre parameters without requiring continuous complex processing throughout the entire playback duration.
Solution Approach 2:
The system allows users to pre-set timbre control parameters and time points before playback begins. These settings are stored and automatically executed during playback, eliminating the need for real-time complex processing and reducing system complexity while maintaining versatile timbre control.
2Ease of operation
If timbre control at specific times is implemented, then audio control flexibility is improved, but information processing complexity increases
Solution Approach 1:
The patent uses data files to store and transmit timbre control information, effectively creating a copy of the control parameters that can be processed independently from the audio signal itself. This separates the control information from the audio data, simplifying the processing requirements.
Solution Approach 2:
The system introduces an intermediary data file that carries timbre control information between the user interface and the audio processing engine. This intermediary structure organizes the complex control information in a manageable format, reducing the processing burden on the main system.
3Adaptability or versatility
If multiple timbre control parameters are set for different time points, then musical practice customization is enhanced, but data management complexity increases
Solution Approach 1:
The patent creates a universal data file format that can store multiple timbre control parameters across different time points and different musical pieces. This multi-functional data structure handles various customization scenarios without requiring separate management systems for each case.
Solution Approach 2:
The system merges the audio signal data and timbre control information into a coordinated transmission package, where both are sent together to the output device. This combining approach ensures synchronization and reduces the need for separate data management processes.

AI summary
This information processing device comprises: a control unit which receives an input of information indicating one or more timings in a playback time of a piece of music, and generates a file including information pertaining to a timbre control performed from each of the one or more timings; and a transmission unit which transmits an audio signal of the piece of music and the information pertaining to the timbre control in the file to a device which outputs a synthesized sound of the playback sound of the piece of music and the playing sound of a musical instrument.
