Engines and licensesAbout Add Reverb
Reverb imitates how sound bounces around a real space, and it's what stops a dry recording from sounding flat. Choose one of four spaces with their own character — room, hall, plate and cathedral — or a custom mode where you set the reverb amount, from 0 to 200%, and the size of the space. Unlike the slowed effects, neither the speed nor the pitch changes here.
What you can do with it
- 01
Podcasts and voiceovers
A very low room reverb takes the dryness off a voice recorded in a treated room without losing clarity.
- 02
Lead vocals
Plate adds sparkle and presence to pop, rock or R&B vocals, and it's great on snare drums too.
- 03
Ambience and soundtracks
Cathedral turns pads, choirs or slow effects into something immense, perfect for cinematic moments.
- 04
Tracks recorded separately
Putting several tracks in the same space helps them sound like they were played together, so the mix feels more cohesive.
How it works, in 3 steps
Load your file
Upload MP3, WAV, FLAC, AAC or OGG audio. The drier it is, with no reverb already on it, the more control you'll have.
Choose the space
Each type has a starting amount: room 35%, plate 50%, hall 60% and cathedral 85%. In Custom you start from zero and also choose the size.
Adjust and download
Move the slider until it sits just right, listen to the result and download it as WAV, MP3, FLAC or OGG.
The four spaces
Room
A short tail, under a second, with strong early reflections. The most discreet one and the one that fits almost anything.
Hall
The acoustics of a concert hall: a smooth, enveloping tail of one to three seconds. Great for strings, piano, ballads and pads.
Plate
Recreates vintage metal plate reverbs: bright, smooth and slightly colored. A classic on vocals and snares.
Cathedral
A gigantic space with very long tails. It blurs fast rhythms, so save it for slow or sustained material.
Custom
Start from zero, push the amount up to 200% and choose the size of the space, from small to huge, which sets the length of the tail.
Tips for better results
- For most voices and instruments, start between 30 and 50% and adjust by ear.
- If you hear the reverb as something separate from the sound, you've probably overdone it: pull it back a little.
- Always keep the dry original. Once added, reverb is hard to remove.
- For different amounts in different sections, cut with Audio Trimmer, process each part and join them with Audio Joiner.
Frequently asked questions
Which type of reverb should I choose?
Room for voices, podcasts and almost any source; plate for lead vocals and drums; hall for orchestral music, ballads and pads; cathedral for ambience and epic moments. If in doubt, start with room.
How much reverb should I put on a voice?
For podcasts and voiceovers, 20 to 35%, so the space is noticeable without losing clarity. For singing, 35 to 50%. Above 60% the reverb stops supporting the voice and becomes the effect.
What's the difference between reverb and delay?
Reverb is a dense cloud of reflections that blend together and sound like a space. Delay is separate, recognizable repeats, like an echo. This tool adds reverb.
Can I add it to a song that's already mixed?
Yes. It works on full mixes, instrumentals or karaoke tracks. On a whole mix, a moderate amount adds ambience without muddying it.
Why does it sound muddy after adding reverb?
Probably too much of it, or a hall or cathedral on fast material: long tails cover the hits. Lower the amount or switch to room.
How is it different from Slowed + Reverb?
Here the audio keeps its speed and pitch: it's a production tool. Slowed + Reverb also slows the song down for an atmospheric sound made for edits and social media.
