When several people sing the same note, they're never perfectly in tune or in time. That small mismatch is what makes a choir sound wide. A chorus effect fakes it by layering copies of your sound, each slightly delayed and wavering in pitch.

Two voices give a gentle shimmer. Four with the depth turned up gives the watery guitar sound of 1980s pop.

How to use the Chorus Effect tool

  1. Add your audio file.
  2. Choose the number of voices and the depth.
  3. Apply the chorus and save the thicker version.
  • Widening a thin backing vocal
  • Clean electric guitar and synth pads
  • Making a single clap or shout sound like a group

Tips for the best result

  • Keep the depth under 50% on lead vocals or the tuning starts to sound off.
  • Chorus works best on sustained sounds and does little for drums.

Frequently asked questions

Will it make one singer sound like a real choir?

It adds width and movement. It does not create different voices, so it will not pass for a real choir.

Does it change the length or the key?

No. Length and key stay the same.

What is the difference between chorus and flanger?

A flanger uses a shorter delay and feeds the sound back into itself, which gives a sweeping jet sound.

Can I use it on speech?

Yes, lightly. With two voices at low depth it thickens a thin recording.
