The Hetrodyne Filter as a Tool for Analysis of Transient Waveforms

Abstract

A method of analysis of transient waveforms is discussed. Its properties and limitations are presented in the context of musical tones. The method is shown to be useful when the risetimes of the partials of the tone are not too short. An extension to inharmonic partials and polyphonic musical sound is discussed.
