ABSTRACT:
A process and a device for the musical and vocal dynamic sound synthesis of formants associated with a fundamental sound. To produce a formant, a wave form is generated with is the sum of several sound components of the form ##EQU1## wherein .omega..sub.0 denotes the angular frequency of the fundamental sound, .omega..sub.s denotes a shift of angular frequency of the formant with respect to the fundamental sound, .omega..sub.c denotes the central angular frequency of this formant, and .delta. denotes the bandwidth of the latter. The amplitude of each component is of the form: ##EQU2## The frequency or angular frequency parameters are modulated temporally in order to carry out the dynamic sound synthesis, the phase relations between formants thus being preserved.
