Electronic Music Effect Generator with FPAA

Abstract

The timbre of many musical instruments can be modified and coloured with electronic effects. In instruments where the sound produced is essentially sinusoidal or nearsinusoidal, it is common to alter the timbre of these instruments electronically. Two approaches to this are now used; signal modification or frequency domain spectrum modification. Of course, the relationship between the two can be described by Fourier transforms. Most commonly, effects equipment is used for guitar, electronic guitar. With this article we describe some approaches to this and give recommendations for its implementation with FPAA.
