Timbre Simulation Transfer Function for Stringed Instruments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for modifying the sound timbre of electrical stringed musical instruments rely on assumptions that timbre depends exclusively on pickup position and require hexaphonic pickups, limiting their ability to accurately simulate the sound of one instrument as another, especially without additional components or instruments.
Innovation Solution
A device and method that acquire and filter electrical signals from a source instrument using a transfer function correlating the sound profiles of a target instrument, allowing for simulation of timbre without hexaphonic pickups, enabling economic and time savings, and accommodating different playing techniques and settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If hexaphonic pickups and additional components are used to modify sound timbre, then the accuracy of instrument simulation is improved, but the device complexity and cost increase
Solution Approach 1:
The invention extracts the essential timbre characteristics from reference recordings and separates them from the need for complex hardware modifications. By using audio recording and playback equipment to capture and analyze timbre profiles, the system removes the requirement for hexaphonic pickups and complex mathematical modeling, achieving accurate simulation through simpler audio processing techniques
Solution Approach 2:
The invention creates audio copies of reference instrument timbres through recording and stores them for playback. Instead of attempting to physically replicate the sound generation process through complex pickups and mathematical models, the system directly copies the acoustic output of reference instruments and reproduces it through standard audio equipment, achieving identical timbre simulation with simpler hardware
2Measurement precision
If hexaphonic pickups are required for timbre modification, then the timbre simulation capability is improved, but the ease of operation and accessibility deteriorate
Solution Approach 1:
The system performs automatic timbre analysis and profile extraction from reference recordings without requiring manual setup of complex pickup configurations or mathematical models. The audio processing equipment automatically captures, analyzes, and stores timbre characteristics, eliminating the need for users to perform complex calibration procedures or understand sophisticated technical concepts
Solution Approach 2:
The invention introduces audio recording and playback equipment as an intermediary between the instrument and the simulation process. Instead of directly manipulating electrical signals from complex pickups, the system uses audio recordings as a mediator to transfer and reproduce timbre characteristics, simplifying the user interface and making the system accessible to musicians without technical expertise
3Adaptability or versatility
If mathematical modeling of pickup positions is used, then the timbre modification capability is improved, but the time required for setup and configuration increases
Solution Approach 1:
The system performs timbre analysis and profile extraction in advance during the recording phase. By capturing and storing complete timbre profiles from reference instruments before use, the system eliminates the need for time-consuming mathematical modeling and calibration during performance or setup, allowing immediate application of authentic timbre characteristics

AI summary
A device for simulating a sound timbre, particularly for stringed electrical musical instruments, which comprises input elements for acquiring an electrical signal generated by a musical instrument, and filtering elements which operate on the electrical signal generated by a source musical instrument. The filtering elements apply to the electrical signal generated by the source musical instrument a transfer function obtained by correlating the sound profile of a target musical instrument to the sound profile of the source musical instrument, the sound profiles comprising respectively the average frequency spectrum of a range of notes played on the target musical instrument and the average frequency spectrum of a corresponding range of notes played on the source musical instrument. The sound profiles are defined on the basis of the electrical signals generated by the musical instruments, corresponding to the playing of at least one note per string.
