A set of pitch tracking, harmonically related resonance filters for monophonic signals

Abstract

This processor facilitates a range of timbral manipulations and resynthesis approaches for monophonic input signals. The input signal’s fundamental frequency is tracked, and the signal is passed through a series of 11 resonance filters, each tuned to an integer multiple of the input signal’s fundamental frequency over time. Alternatively, white noise can be harmonically filtered using the fundamental frequency data of an input signal. This creates a synthetic tone which mimics the input signal melodically, but whose timbral qualities are defined by the user input. This report includes a brief outline of the signal flow, and some discussion of the possible applications and usefulness of this processor.
