Add reverb to audio
Three spaces, one click: tuck a dry track into a small room, open it up in a hall, or drown it in a cathedral.

Reverb is the wash of reflections a sound makes as it bounces off the walls, floor, and ceiling of a space before it fades out. Your ear reads those reflections as size and distance, which is why a close-mic'd or AI-generated vocal can sound flat and pasted on top of a track — there's no room around it. Adding reverb online places that dry recording somewhere, so it sits inside the mix instead of hovering in front of it.
The room, hall, and cathedral presets step up in scale: a short, tight decay for presence, a longer musical tail, and a long, washed-out space used deliberately as an effect. It's the same idea whether you're finishing a Suno vocal, a voiceover, or an acapella — you trade a little dryness for depth and glue. Everything renders locally in your browser, so the file you drop in never leaves your device.

When to use it
- A Suno vocal that came out dry and close-mic'd — a hall preset gives it a tail so it blends into the instrumental instead of floating on top.
- A voiceover recorded on a phone or laptop for a YouTube or TikTok video, where a light room preset adds a sense of space and makes it feel less bare.
- An acapella or spoken-word clip you're turning into a distant, atmospheric piece for a lo-fi or ambient edit before posting it to SoundCloud.
FAQ
Which preset should I start with?
Hall is the safe middle — noticeable but musical. Room adds presence without obvious echo; cathedral is a deliberate effect.
Can I control the mix amount?
Not yet — the presets are balanced blends. For the drenched slowed + reverb sound, use that dedicated tool.
What's the difference between reverb and echo or delay?
Delay repeats the sound as distinct, separated copies you can count. Reverb is hundreds of reflections packed so tightly they blur into one smooth tail, which your ear reads as a room rather than a repeat.
Can I add reverb to just the vocals in a finished song?
No — this applies reverb to the whole file, so on a full mix the drums and bass get wet too and can turn muddy. For vocals-only reverb, isolate the vocal first (a stem or acapella), add reverb to that, then layer it back over the instrumental.
Should I add reverb before or after changing the speed or pitch?
After. Reverb usually comes last in the chain so its tail reflects the final tempo and key — if you slow the track down afterward, the reverb stretches along with it and smears. That's exactly the order the slowed + reverb tool handles for you.
