Abstract/Artist Statement
The purpose of this project is to create an analogbased audio effect system that is reminiscent of older systems used before digital effects became popular. Two different audio effects were implemented in this project: a Phaser and an Equalizer. A Phaser was originally used as a guitar effect, and remains one of the most popular after being heavily utilized by Jimi Hendrix. Equalizers allow the volume of individual pitch ranges to be changed independent of each other, and are used in all types of audio systems from home theaters to studio production. All filters required by these audio effects were designed from the ground up mathematically with MATLAB, then simulated electrically with spice software. The final product is a series of custom-made Printed Circuit Boards (PCBs).
