Patent Number Title Of Patent Date Issued
5777255 Efficient synthesis of musical tones having nonlinear excitations July 7, 1998
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 r
5748513 Method for inharmonic tone generation using a coupled mode digital filter May 5, 1998
A coupled mode digital filter which simulates any number of arbitrarily tuned modes coupled together so as to share the same loss element at a junction loaded by an arbitrary impedance function is formed from the combination of one first order allpass filter [28] and one unit delay [30]
5742532 System and method for generating fractional length delay lines in a digital signal processing sy April 21, 1998
A sampled data, non-integer delay line interpolation structure includes a sampled data delay line, two allpass filters, each having an associated read pointer for reading data at a corresponding integer position of the delay line, an alternating crossfader that alternatingly crossfades
5703313 Passive nonlinear filter for digital musical sound synthesizer and method December 30, 1997
A music synthesizer includes main resonator, such as a digital waveguide network, that is coupled to a digital passive nonlinear filter. The passive nonlinear filter receives traveling wave signals from the resonator and generates modified traveling wave signals having a different fr
5614686 Multidimensional digital waveguide signal synthesis system and method March 25, 1997
A signal synthesizer uses a digital waveguide network having at least a three dimensional matrix of waveguide sections interconnected by junctions to filter one or more excitation signals so as to generate an array of synthesized output signals. The digital waveguide network has sets of
5471007 Multidimensional digital waveguide signal synthesis system and method November 28, 1995
A signal synthesizer uses a digital waveguide network having at least a two dimensional matrix of waveguide sections interconnected by junctions to filter one or more excitation signals so as to generate an array of synthesized output signals. The digital waveguide network has sets of
5466884 Music synthesizer system and method for simulating response of resonant digital waveguide struck November 14, 1995
A musical sound synthesizer simulates interaction of a hammer having a compressible striking surface with a resonating medium. A digital waveguide resonator that simulates operation of a resonating medium and generates digital resonator waveforms representing signals propagating in s
