Music synthesizer and method for simulating period synchronous noise associated with air flows in wind instruments

A musical sound synthesizer, comprising:

• a stimulus source for providing a stimulus signal;
• a noise generator that generates a noise signal N;
• a nonlinear signal generator coupled to said stimulus source and to said noise generator and having an output, said nonlinear signal generator generating a signal Z on said output that is a function of said stimulus signal using a nonlinear polynomial of the form ##EQU2## where X corresponds to said stimulus signal and M is an integer larger than 1, and B.sub.i and C.sub.i are constants;
• an acoustic signal resonator that is driven by said signal Z and generates a musical sound signal;
• and
• an output for transmitting an output signal corresponding to said musical sound signal.

A method of synthesizing sounds, the steps of the method comprising:

• generating an audio output signal and a feedback signal with an audio resonator;
• generating an excitation signal;
• combining said excitation signal with said feedback signal to generate a differential excitation signal;
• generating a noise signal;
• performing a non-linear transformation of said differential excitation signal to produce a non-linear excitation signal, wherein said non-linear transformation is controlled by said noise signal;
• driving said acoustic signal resonator with said nonlinear excitation signal so as to generate said audio output signal;
• and
• transmitting an output signal corresponding to said audio output signal.
