Physical Modelling

This area includes any means of synthesizing sound "from scratch" or "first principles" through a mathematical acoustical model, generally of an existing musical instrument. Normally based on models of the manner in which a resonator responds to some form of excitation (i.e. energy input), two frequently encountered examples are Waveguide Synthesis Karplus Strong techniques for the simulation of plucked strings and membrane instruments.

Synthèse par modèle physique

Ce domaine comprend toutes les techniques de synthèse du son partant de zéro ou partant des principes premiers d'un modèle acoustique mathématique, généralement un instrument de musique existant. Cette technique est habituellement fondée sur des modèles dans lesquels un résonateur répond à une certaine forme d'excitation (c'est-à-dire un apport d'énergie). Les exemples généralement présentés sont les techniques de synthèse par guide d'onde (waveguide) de Karplus et Strong pour la simulation d'instruments à cordes pincées ou d'instruments à membranes.

Modello Fisico

Il termine indica le tecniche di sintesi che partono da una descrizione semplificata del mondo fisico e lo ricreano attraverso un modello acustico matematico, utili in acustica per ricreare uno strumento musicale esistente. È una tecnica fondata su modelli nel quale un risuonatore risponde a una certa forma di eccitazione (per es. un impulso di energia). Le tecniche più utilizzate sono quelle per guide d'onda (waveguide) di Karplus et Strong per la simulazione delle corde pizzicate o degli strumenti a membrana.

“All'origine della sintesi per modelli fisici vi è l'assunto che il segnale possa essere calcolato sulla base di equazioni che descrivano il comportamento fisico (acustico e meccanico) dei corpi che interagiscono nella sua produzione” (Lombardo-Valle, Audio e multimedia, 2 ed , 195).

Modelo Físico (Physical Modelling)

Este área incluye cualquier modo de sintetizar un sonido "a partir de cero" utilizando un modelo acústico matemático, generalmente el de un instrumento musical ya existente. Basados sobre modelos en los que un resonador responde a alguna forma de excitación (es decir, de energía de entrada), dos ejemplos típicos son las técnicas de Síntesis por Guía de Ondas de Karplus y Strong para la simulación de cuerdas punteadas e instrumentos de membrana.
