Types of audio effects

Audio effects can be broadly classified into four types: dynamic, temporal, modulation, and harmonic effects. Each type serves a unique purpose in shaping the sound.

The effects are best understood when they are heard. So we will compare the sounds with the effects on and off. Note that when a sound has no effect on it, we call it “dry.”

1. Reverb

Reverb (which is short for “reverberation”) simulates the natural reflections of sound in a space. It’s the difference between hearing a singer in a small room or in a cathedral. When a recording lacks reverb, it makes us feel like it exists in a vacuum, which can sound very unnatural. It will be flat and very close to the listener. Adding a little reverb will create a sense of depth and dimension.

Let’s hear what reverb can do to a clap sound. Here is the dry sample without reverb:
