Note and Hammer Velocity Dependence of a Piano String Model Based on Coupled Digital Waveguides
نویسندگان
چکیده
Previous works have shown that a combination of digital waveguide and signal models allows a perfect resynthesis of the sound generated by a string struck by a hammer. In particular the non-linear behavior of the hammer/string interaction is well reproduced. However, in an acoustic piano, two or three strings are struck by the same hammer, and the characteristics of the strings and the hammers are different from the bass to the treble. To take into account these considerations, the model for one piano string is extended so that it can generate notes produced by two and three strings. The behavior of the model parameters (the resonant part and the excitation part) is then studied, with respect to the velocities and the notes played. This research is an essential step in the design of a complete piano model.

A Hybrid Resynthesis Model for Hammer-String Interaction of Piano Tones
This paper presents a source/resonator model of hammer-string interaction that produces realistic piano sound. The source is generated using a subtractive signal model. Digital waveguides are used to simulate the propagation of waves in the resonator. This hybrid model allows resynthesis of the vibration measured on an experimental setup. In particular, the nonlinear behavior of the hammer-stri...
متن کاملPhysics - Based Sound Synthesis of the Piano Balázs Bank
The present work is about the synthesis of piano sound based on the grounds of physical principles. For that, rst the acoustical properties of the piano have to be understood, since the underlying physical phenomena establish the framework for the model-based sound synthesis. Therefore, the di erent parts of the piano were measured and analyzed. The groundwork of the piano model lies in the dig...
متن کاملPiano Hammer-String Interaction
A hammer-string interaction for bass notes is investigated and the problem what can cause the hammer to rebound is clarified. For a linear elastic hammer interacting with a long flexible string the exact solution of the equation describing the hammer motion is derived. It was shown that in some cases no reflected wave is needed to assist the hammer for going away from the string. The numerical ...
متن کاملCommuted Piano Synthesis
The \commuted piano synthesis" algorithm is described, based on a simpli ed acoustic model of the piano. The model includes multiple coupled strings, a nonlinear hammer, and an arbitrarily large soundboard and enclosure. Simpli cations are employed which greatly reduce computational complexity. Most of the simpli cations are made possible by the commutativity of linear, time-invariant systems. ...
متن کاملJ. Rauhala and V. Välimäki, Parametric excitation model for waveguide piano
In this paper, a method providing an excitation signal for the waveguide piano synthesis is presented. The waveguide synthesis string model needs an excitation signal, which stimulates the model to resonate at the partial frequencies. This signal simulates the force pulse, which occurs in the piano when the hammer hits the string. In the proposed method, the excitation signal is produced by usi...
