DSP Audio Effect Applications
by Thomas Stepp
Introduction
If you listen to music, there's a guarantee that you will not hear the exact voice of a singer or the immediate output of an instrument. Instead musicians and vocalists use effects to enhance their sound, craft a unique tone, and as a tool to express themselves.
Some commonly used effects are reverb (to sound like you are playing in a large room), distortion (to achieve a harsher tone and add harmonics), and delay (to create an echo or repeating effect). Many of these were initially created through analog circuits, but it is increasingly more popular to use digital implementations as technology improves and becomes cheaper.
