  • Programmable tone control filters for electric guitar
    Publication number: 20070168063
    Abstract: A method and apparatus for simulating the characteristics of an analog tone control circuit using digital computation means. The desired analog tone control circuit is modeled using initial treble, middle, and bass settings, following which simulation software is used to generate the model's magnitude and phase responses versus frequency, extending over the desired frequency range. Gains, zeroes and poles are then chosen to produce magnitude and phase versus frequency response matching as closely as possible to that of the simulated circuit. A bilinear transformation is then performed to produce a digital filter prototype. Update equations responsive to treble, middle, and bass settings of the simulated tone control circuit are then designed in a specified form, providing for modification of the digital filter parameters as a function of updates in the treble, middle, and bass settings of the simulated tone control circuit.
