Guitar Effects Generator using DSP

By: Alex Czubak and Gorav Raheja
Advisor: Dr. Thomas L. Stewart

Abstract

This project deals with the creation of sound effects through manipulation of an audio signal from a guitar. The signal is processed through a digital signal processor that contains a number of digital filters to modify the signal to include the desired effects. The altered signal is then sent to a guitar amplifier as audio. There are a total of eight guitar effects that can be processed: Distortion, Reverberation, Delay/Echo, Octaver, Volume Envelope, Chorus, Flanger, and Phase Shifter. These effects are controlled by a graphical user interface, allowing the user to select which effects are active and to what degree.
