Reverb Effect Generator

Add professional reverb effects with 9 presets: Small Room, Hall, Cathedral, Canyon, Bathroom, Plate, Spring, and Studio. Adjust pre-delay, decay, wet/dry mix, and frequency damping.

Add reverb to dry audio to create a sense of space. Choose from room simulations, small room, large hall, cathedral, plate, or dial in custom decay time, pre-delay, and wet/dry mix. Reverb transforms a close-miked recording into something that sounds like it was captured in a real acoustic environment.

Audio to Sheet Music

Transcribe audio into sheet music using Basic Pitch neural network running in your browser. Handles humming, singing, solo instruments, piano, guitar, and full mixes. Auto-detects tempo, key, and staff type (treble/bass/grand); supports title/composer metadata, snap-to-key cleanup, live transpose, and exports to MIDI, MusicXML, SVG, PNG, or print.

Reverb Effect Generator: a worked example

A dry vocal needs a tasteful room ambience so it does not sound recorded in a closet.

Input

vocal.wav · "medium room" · decay 1.2 s · mix 18%
Reverb Effect Generator produces

Output

Vocal with subtle spatial depth, still intelligible

Convolution/algorithmic reverb adds the reflections a real space would, and keeping the wet mix low preserves clarity while removing the lifeless dry sound. Decay length sets the perceived room size.

Common use cases

  • Vocal production

    Add a plate or room reverb to a dry vocal recording to give it polish and depth.

  • Sound design

    Create long, ethereal reverb tails for ambient music or cinematic soundscapes.

  • Podcast atmosphere

    Apply a subtle room reverb to make a studio recording sound less sterile.

  • Matching recordings to video

    Add reverb that matches the visual environment, a large hall sound for footage shot in a church, for example.

How it works

Reverb simulates the reflections that occur when sound bounces off surfaces in a physical space. Pre-delay is the gap before the first reflections arrive, which affects the perceived size of the room. Decay time controls how long reflections persist before fading to silence, short decay suggests a small, absorptive room, while long decay evokes a cathedral or concert hall. The wet/dry mix determines how much processed signal blends with the original. Subtle settings add depth without drowning clarity; heavy settings create ambient washes and atmospheric textures.

Frequently asked questions

What is pre-delay?

Pre-delay is the time gap between the dry signal and the onset of reverb reflections. Longer pre-delay makes the source sound farther from the walls.

How much reverb should I use?

Start with the wet/dry mix low (15-25%) and increase until you hear the space without losing clarity. Less is usually more for speech.

Can I remove reverb from a recording?

This tool adds reverb. Removing existing reverb requires de-reverberation algorithms, which is a different process.
