Title (EN) PARAMETRIC SIGNAL MODELING MUSICAL SYNTHESIZER
(FR) SYNTHETISEUR MUSICAL A MODELISATION PARAMETRIQUE DES SIGNAUX
Abstract:
(EN) A parametric signal modeling musical tone synthesizer utilizes a multidimensional filter coefficient space consisting of many sets of filter coefficients to model an instrument. These sets are smoothly interpolated over pitch, intensity, and time. The filter excitation for a particular note is derived from a collection of single period excitations, which form a multidimensional excitation space, which is also smoothly interpolated over pitch, intensity, and time. The synthesizer includes effective modeling of attacks of tones, and the noise component of a tone (101) is modelled separately from the pitched component (102). The input control signals (111) may include initial pitch and intensity, or the intensity may be time-varying. A variety of instruments may be specified.
(FR) Synthétiseur de sons musicaux à modélisation paramétrique des signaux qui utilise un espace de coefficients de filtre multidimensionnel consistant en de nombreux jeux de coefficients de filtre pour prendre modèle sur des instruments. Ces jeux sont interpolés de manière lisse sur le ton, l'intensité et la durée. L'excitation du filtre pour une note particulière est dérivée d'un groupement de périodes d'excitation isolées formant un espace d'excitation multidimensionnel qui est également interpolé de manière lisse sur le ton, l'intensité et la durée. Ledit synthétiseur comporte une modélisation effective des attaques de sons et la composante bruit d'un son (101) est modélisée séparément de la composante ton (102). Les signaux (111) de commande d'entrée peuvent inclure un ton et une intensité initiales, ou bien l'intensité peut varier avec la durée. Toute une gamme d'instruments peut être spécifiée.
