Commuted Piano Synthesis

چکیده
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. Special care is given to the felt-covered hammer which is highly nonlinear and therefore does not commute with other components. In its present form, a complete, two-key piano can be synthesized in real time on a single 25MHz Motorola DSP56001 signal processing chip.

Developments for the Commuted Piano
We present here three developments for the Commuted Piano Synthesis model described more fully elswhere in these proceedings [3]: (1)a theoretical foundation and calibration scheme for the required linearized piano hammer system; (2) a simple algorithmic synthesis approach for the commuted soundboard impulse response, eliminating the need for any wave table memory; and (3) a calibration method ...
متن کاملNonlinear Commuted Synthesis of Bowed Strings
A commuted-synthesis model for bowed strings is driven by a separate nonlinear model of bowed-string dynamics. This gives the desirable combination of a full range of complex bow-string interaction behavior together with an efficiently implemented body resonator. A “single-hair bow” may control a pulsed-noise version which provide the effects of multiple bow hairs. The pulsed noise may also inc...
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...
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 کاملA laboratory investigation on the potential of computational intelligence approaches to estimate the discharge coefficient of piano key weir
The piano key weir (PKW) is a type of nonlinear control structure that can be used to increase unit discharge over linear overflow weir geometries, particularly when the weir footprint area is restricted To predict the outflow passing over a piano key weir, the discharge coefficient in the general equation of weir needs to be known. This paper presents the results of laboratory model testing of...
