Patent ID: 7915515

Claim:
A device for production, by digital means, of signals that are representative of sounds having a sonority simulating that of an instrument having a keyboard and having strings that are linked to a sounding-board of the instrument, these sounds each corresponding to a note of the instrument, comprising: at least one module for production of sounds by digital means in real time, adapted to produce at least one signal that is representative of a sound starting from at least one triggering signal relating to the playing of an instrumentalist, and by use of coefficients that are representative of at least one string parameter characteristic of at least one string of the instrument to be simulated and representative of a measurable physical property of said at least one string having an influence on the timbre of the sounds produced by the instrument, wherein, said device comprises at least one presynthesis module adapted to produce timbre coefficients that are representative of the damping of each exponentially damped sinusoidal partial composing a sound, and timbre coefficients that are representative of the frequency of each partial, said at least one presynthesis module producing said timbre coefficients starting from physical parameters comprising: at least one sounding board parameter characteristic of a sounding-board of the instrument to be simulated and representative of a measurable physical property of this sounding-board having an influence on the timbre of the sounds produced by the instrument, said at least one string parameter, said at least one module for production, in real time, of sounds by digital means is adapted to produce at least one signal that is representative of a sound composed at least of a plurality of partials with said timbre coefficients produced by said at least one presynthesis module, and starting from at least one triggering signal relating to the playing of an instrumentalist.
