How to Add Reverb

  1. Choose your audio – a vocal, instrument, song, voice-over or video soundtrack.
  2. Pick a reverb space.
  3. Set Amount (how much reverb is mixed in) and Size (how long it rings).
  4. Compare wet and dry, then download.

The Six Spaces

  • Warm Room: A short, natural ambience that makes dry home recordings sound less "boxy".
  • Concert Hall: Smooth and wide – great for vocals, piano and strings.
  • Stone Chamber: Bright and dense, with clear early reflections.
  • Cathedral: A very long, majestic tail for choirs, pads and ambient music.
  • Deep Cave: Dark and huge – for sound design, trailers and atmosphere.
  • Vintage Plate: The classic studio plate sound heard on many pop and rock vocals.

Slowed and Reverb

The popular "slowed + reverb" style is easy to make: slow the song to about 0.8× with pitch following in Audio Speed and Pitch Changer, then add Concert Hall or Cathedral with a high amount here.

Tips

  • Less is more on speech. Podcasts and voice-overs need only a touch of Warm Room – too much makes words hard to follow.
  • Match the music. Fast songs need short reverbs; slow songs can carry long ones.
  • Keep the original. Reverb cannot be removed afterwards, so save a copy of the dry file.

Free and Private

Reverb is calculated in your browser, so your recordings are never uploaded. For repeating echoes instead of a smooth tail, try Add Echo to Audio.
