Abstract:
A system (1) used to reproduce the sound of a stringed instrument provided with hammers striking the strings is disclosed. The system comprises speed detection means coupled with each hammer to detect the percussion velocity on the string, a plurality of note modules receiving in input a signal representative of the hammer velocity and generating a force signal (F tot ) representative of the global partial components of the string vibration, and a soundboard-instrument body module (700) receiving in input said signal of the global partial components (F tot ) from each note module and generating two electrical signals (left, right) adapted to drive two electroacoustic transducers for sound emission.
Abstract:
An efficient digital waveguide synthesizer is disclosed for simulating the tones produced by a non-linearly excited vibrational element coupled to a resonator, such as in a piano. In a preferred embodiment, the synthesizer creates an excitation pulse from a table containing the impulse response of a piano sound board and enclosure. Alternately, this excitation pulse can be synthesized by filtering white noise. The excitation pulse is fed into the filter that simulates the collision of the piano hammer and string. Because the hammer-string interaction is nonlinear, the characteristics of this filter vary with the amplitude of the tone produced. The filtered excitation pulse is then fed into a filtered delay line loop which models the vibration of a piano string. Because the excitation pulse already contains effects of the resonator, the tone produced by the delay line loop does not require additional filtering in order to model the resonator.
Abstract:
An electronic music system (400) which imitates acoustic instruments addresses the problem wherein the audio spectrum of a recorded note is entirely shifted in pitch by transposition. The consequence of this is that unatural formant shifts occur, resulting in the phenomenon known in the industry as ''munchkinization''. The present invention eliminates munchkinization, thus allowing a substantially wider transposition range for a single recording. Also, the present invention allows even shorter recordings to be used for still further memory improvements. An analysis stage (50) separates and stores the formant and excitation components of sounds from an instrument. On playback, either the format component or the excitation component may be manipulated.
Abstract:
Accordingly, the invention relates to a device for digitally producing signals representative of sounds having a sonority simulating that of an instrument with keyboard and strings that are linked to a sounding board of the instrument, these sounds each corresponding to a note of the instrument. The device according to the invention is adapted for being able to produce at least one signal representative of a keyboard and stringed instrument sound on the basis of at least one trigger signal and parameters, termed physical parameters. The physical parameters according to the invention comprise at least one parameter, the so-called sounding-board parameter, characteristic of a sounding board of a keyboard and stringed instrument to be simulated. Furthermore, the physical parameters according to the invention comprise at least one parameter, termed the string(s) parameter, characteristic of at least one string of the keyboard and stringed instrument to be simulated. The device according to the invention comprises means (9, 10, 11, 33) for inputting at least one physical parameter.
