Slowed + Reverb Maker
Slow any track down for that slowed sound. Drag the wheel down to slow it and drop the pitch, the vibe all over TikTok and YouTube, then export a WAV. For the full slowed and reverb effect, add a touch of reverb in your editor. Everything runs in your browser.
Drag the wheel, scroll over it, or use ←→. Double‑click to reset.
Varispeed moves pitch + speed together (tape/turntable, the slowed & nightcore sound). Pitch changes the key but keeps the speed. Speed changes the tempo but keeps the pitch (slow down without the chipmunk effect). Pitch & Speed use a time‑stretch engine, so big shifts have mild artifacts; varispeed is artifact‑free.
100% local. Your file is decoded, processed, and exported entirely on your device, nothing is uploaded or used to train anything. The same principle behind Xport Studio.
How to make a slowed version of a song
- Drop your song into the tool above (MP3, WAV, FLAC, M4A, or OGG).
- Stay on Varispeed. It moves pitch and speed together, the same way a tape deck or turntable does, and that coupled drop is the slowed sound.
- Drag the wheel down to -2 or -3 semitones. That lands you in the classic 80 to 90 percent speed range. Tap the -5 preset if you want it noticeably deeper.
- Press Play and audition the whole hook, not just the intro. Nudge the wheel with the arrow keys until the vocal sits where you want it.
- Hit Export WAV, then add reverb in your editor for the full slowed and reverb finish.
What is slowed + reverb?
A slowed and reverb edit is a song played back below its original speed, usually between 80 and 90 percent, with the pitch dropping along with the tempo. Vocals sit lower and heavier, drums drag, and the track takes on a darker, half-asleep character. The second half of the name is a generous coat of reverb over the slowed mix, which pushes everything back in space and makes the edit feel wide, distant, and dreamlike.
The technique traces back to chopped and screwed DJ culture in 1990s Houston, where DJ Screw slowed records down and cut between two copies of the same track. Decades later the slowed half of that idea resurfaced as the slowed + reverb edit wave on YouTube, then spread through TikTok, where slowed versions regularly outrun the originals in plays. People make these edits for plain reasons: shifting a bright song into a moodier register, building study or late-night playlists, or making fan edits that hit differently at 85 percent.
Best settings for a slowed + reverb edit
- 85 percent speed is the classic starting point. On this wheel, -3 semitones in Varispeed gives you 84 percent, close enough that nobody will argue.
- 80 percent for a deeper vibe. That is about -4 semitones. The vocal gets heavier and the groove really drags.
- Keep the vocals intelligible. Below roughly 75 percent (the -5 preset and beyond), consonants smear and lyrics get hard to follow. If the words matter, stay above that line.
- Reverb comes after export. This tool does the varispeed slow-down; it does not add reverb. Drop the exported WAV into any DAW or free editor and add a hall or plate reverb: long decay, around 2 to 4 seconds, mixed at 15 to 25 percent wet, with a short pre-delay so the vocal stays readable inside the wash.
Slowed + reverb vs nightcore
Same trick, opposite directions. Slowed and reverb takes the track down: slower tempo, lower pitch, heavier mood. Nightcore takes it up: faster tempo, higher pitch, usually 120 to 130 percent speed. For the sped-up version use our Nightcore Maker; for finer control, like changing pitch without touching tempo, use the pitch and speed changer.
FAQ
What speed is best for slowed and reverb?
85 percent is the accepted classic, which is about -3 semitones on this wheel. Most edits live between 80 and 90 percent: closer to 90 keeps the song recognizable at a glance, closer to 80 leans into the heavy, dragging feel. Below 75 percent you are in chopped and screwed territory and vocals start to blur.
Does slowing a song change its pitch?
In Varispeed mode, yes, and that is the point: pitch and speed drop together, exactly like slowing a record on a turntable. If you only want a slower tempo at the original pitch, switch to Speed mode, but the result will not sound like a classic slowed edit.
Can I make a slowed and reverb edit online for free?
Yes. This tool is free with no account, no watermark, and no export limit. It handles the slow-down and gives you a clean WAV; you add the reverb in any DAW or free audio editor afterward.
Is my song uploaded anywhere?
No. The file never leaves your machine: your browser decodes it, the wheel changes playback locally, and the WAV is rendered on your own CPU. There is no server on the other end, which is the same no-upload principle behind the Xport Studio desktop app.
Can I publish slowed edits of songs I do not own?
Slowing a track down does not change who owns it, so publishing an edit of someone else's song still requires rights or permission from the owner. Making an edit privately for your own listening is a different situation than posting it to YouTube or TikTok.
Does this tool add the reverb too?
Not yet, it handles the slowed half: a clean varispeed slow-down with a full-quality WAV export. Add reverb as the final step in your editor, where you can tune the decay and wet level to the specific track.
When you move past edits and want to slow, split, convert, or master your own vocals and stems, Xport Studio does all of it offline on your desktop.
