Abstract

Un sinteticador de sonido que comprende: medios para acumular cuantos predeterminados de fase durante la generación de un tono de dicho sonido para producir un ángulo de fase; medios acoplados a dichos medios de acumulación para convertir dicho ángulo de fase en una señal que tiene una forma de onda sinusoidal a una frecuencia proporcional al régimen de aumento de dicho ángulo de fase; medios para generar cuantos de fase que se producen aleatoriamente; y medios acoplados a un terminal de entrada de dichos medios de acumulación para sumar dichos cuantos de fase que se producen aleatoriamente con dichos cuantos de fase predeterminados antes de dicha acumulación para ensanchar la línea espectral de dicho tono.
