Vocoders have been practical tools for synthesis and processing since the original voice encoder by Homer Dudley in the 1930s .They enable the transformation and reproduction of an input sound by the manipulation of its spectral envelope.This paper presents a new variation on the principle utilising the technique of Modified FM (ModFM) synthesis for sound generation.The general design of the vocoder is introduced, followed by a non-mathematical introduction to the ModFM synthesis algorithm.The article is completed with an outline of applications and a discussion of some basic examples of the vocoder operation.
