<p>A parametric signal modeling musical tone synthesizer utilizes a multidimensional filter coefficient space consisting of many sets of filter coefficients to model an instrument. These sets are smoothly interpolated over pitch, intensity, and time. The filter excitation for a particular note is derived from a collection of single period excitations, which form a multidimensional excitation space, which is also smoothly interpolated over pitch, intensity, and time. The synthesizer includes effective modeling of attacks of tones, and the noise component of a tone (101) is modelled separately from the pitched component (102). The input control signals (111) may include initial pitch and intensity, or the intensity may be time-varying. A variety of instruments may be specified.</p> |
