Chorus

What Is the Chorus Effect?

The chorus effect is a popular tool used in music production. It is used to make sounds thicker, wider, and more interesting.

The name explains exactly what it does. Think about a real choir of people singing. Even if twenty people try to sing the exact same note at the exact same time, they cannot do it perfectly. Some people will be a tiny bit early or late. Some people will sing slightly sharp or flat. These tiny differences make the choir sound huge and rich. The chorus effect tries to replicate this effect digitally.

How Does a Chorus Effect Work?

When you put a chorus effect on a sound, like a single singing voice, the software makes an exact copy of that voice.

Next, the software takes the copy and delays it just a tiny bit. It is a very short delay, so it does not sound like a separate echo.

Then, the software slowly wobbles the pitch of the copy up and down. Finally, it blends this wobbly, delayed copy back with the original, dry voice. When you hear them together, your ears are tricked. It sounds like two or more people singing the same part together.

Why Use Chorus?

Producers use chorus when a sound is too thin or boring.

It is very famous on guitars. In the 1980s, almost every clean guitar had a chorus effect on it. It makes the guitar sound watery, dreamy, and very wide. It turns a regular guitar into something that fills up the whole room.

It is also used on synthesizers and keyboards. A plain synthesizer note can sound very robotic. Adding chorus gives it movement and life. It makes the digital sound feel more organic and warm.

What Is The Difference Between Chorus And Flanger?

Chorus and flanger are both modulation effects. Because they are in the same effects family, they work in very similar ways. They both make a copy of the sound, delay it, and change the pitch. However, the end result sounds completely different.

The biggest difference is the time of the delay. A flanger uses a very short delay time. It is much shorter than the delay time used in a chorus effect. A flanger also takes the changed sound and loops it back into the start of the effect again.

The very short delay of the flanger creates a very intense sound. A flanger sounds loud and metallic. Many people say a flanger sounds like a large jet plane taking off. A chorus effect uses a longer delay time and does not loop the sound back into itself. As a result, a chorus effect sounds much smoother, softer, and more natural than a flanger.
