What is Reverb ?

What is reverb ?

Reverb is created when a sound occurs in a space, sending sound waves out in all directions. These waves reflect off surfaces in the space, decaying in amplitude until the reflections eventually die off. Without extensive sound-proofing, most spaces will produce many closely spaced reflections, which reach the listener shortly after the initial dry sound. We hear this series of reflections as a single, continuous sound, which we call “reverb.”

Reverb is the persistence of sound after a sound is produced. Reverb is created when a sound or signal is reflected off of a surface causing numerous reflections to build up. They then decay as the sound and reflections are absorbed by the surfaces of the objects around it. The original sound source can stop but the reflections continue, decreasing in amplitude (volume) until they reach zero. Reverb defines how a sound sits in a space. In all aspects of our daily lives, we experience the effects that reverb has on the sounds that we hear.

Understanding Reverb terms

Room size

In fruity Reeverb 2 ,the size parameter allows you to control the size of the space the listener will perceive your sound in. The bigger the size, the longer the reverb will take to occur, and vice versa for smaller size. 


Decay is the most important part of your reverb because it sets the amount of time it takes your reverb to return to silence. When the reverb goes on for too long, everything blends together so you can’t tell one sound from another.

Pre Delay

Pre-Delay gives you space between your dry and wet reverb signal. A lower pre-delay time will give a short amount of time between dry signal and your reverb. This simulates a small room but can sound messy. It’s best to choose mid-sized pre-delay. This will give a slight delay, creating a larger space but keeping the dry signal and reverb clear of each other.

Early Reflection Level

Early reflections sound more like echoes than normal reverb. if you want to create an echo effect, louder early reflections are best for this.Too much echo can interrupt the flow of your music so use lower volumes to create easier blending.

Diffusion Level

Diffusion allows you to add and remove texture from your reverb. Higher diffusion levels simulate a more complex space with many obstructions. It also creates a more smooth sound. Lower diffusion levels simulate a basic shape with unobstructed spaces, like an empty room. Lower levels create a clear sound. Diffusion can also affect the Decay time, so this gives you another option to smooth out your reverb tails.

Mix Level

Your wet/dry mix level (wet/dry) is most important in the process. It determines how your reverb will blend with the other elements of your mix. Adjust the wet/dry mix level to add a little more or a little less until it suits your mix perfectly.

  1. I just started my mixing and mastering course here in the studios under the mentorship of Devang sir. Came back here to revise the topics. Choosing Producernation over other music academies is certainly the best decision I took. Happy to be a part of Producernation’s community.
