Slowed + reverb

How to make a slowed + reverb song online
No account, no watermark, no upload queue. Your file is slowed and reverberated on your own device.
Start from a vibe
Presets that sound right the first time
Each preset is a complete setting — speed, wet mix, space and pitch — so you can hear the sound before you understand any of the controls. Move a single slider and the tool switches to Custom, so nothing is ever locked in.
| Vibe | Speed | Reverb | Space | Pitch | Best for |
|---|---|---|---|---|---|
| TikTok Classic | 80% | 60% wet | Hall | Classic — key drops with the speed | Short-form mood edits |
| Lofi Chill | 85% | 35% wet | Room | Classic — key drops with the speed | Study and late-night playlists |
| Dreamy | 75% | 75% wet | Cathedral | Classic — key drops with the speed | Vlogs, ambient and heavy-space edits |
| Nightcore | 130% | 15% wet | Subtle | Manual +3 semitones | The sped-up flip of a slowed edit |
| Custom | Your sliders | 0–100% | Subtle → Cathedral | Classic, locked or manual | Anything the presets do not cover |
What it does
What a slowed reverb maker actually does
Slow it down or flip it up
One speed control covers both directions: 50% for a full drag, 80% for the classic viral edit, 130% for the nightcore version of the same song. Steps of 1% mean you can land exactly on the feel you want.
Reverb with real rooms behind it
Wet mix goes from fully dry to fully soaked, and the space changes the character: Subtle for a hint of air, Room for a lofi distance, Hall for the TikTok sound, Cathedral when you want the track to float.
Classic tape pitch, locked, or manual
Classic moves the key with the speed, which is where the half-remembered tape quality of a slowed edit comes from. Pitch locked keeps the original key, and Manual drops or lifts up to 4 semitones on top.
Four presets that sound right away
TikTok Classic, Lofi Chill, Dreamy and Nightcore are complete starting points — speed, wet mix, space and pitch all set. Move any slider and the tool switches to Custom, so nothing is ever locked.
Optional bass boost
Light and Medium bass boost lift the low end for the heavier, chopped-and-screwed side of the sound without dragging the whole mix up.
No upload queue
Your file is not stored, logged or used for training. Decoding, stretching, reverb and encoding all run locally in your browser — safe for unreleased demos and voice memos.
Same engine, five sounds
Slowed + reverb, slowed down song, sped up and chopped
The same engine covers several sounds that get searched as if they were different tools. Knowing which one you actually want is most of the job:
Slowed down song, key intact
Speed only, pitch untouched — the version you want for practice tracks, transcript-friendly playback or mixing two versions of the same song together.
75% · Pitch locked
Sped up / nightcore
The mirror image: raise the speed and the pitch instead of lowering them. Useful when the sped-up flip of a track is the thing people are searching for.
130% · +3 semitones · Subtle reverb
Chopped and screwed
Slower speed plus a real pitch drop, often with a heavier low end. Switch pitch to Manual, set −2 to −4 semitones and turn bass boost to Light or Medium.
65% · Manual −3 st · Medium bass boost
Reverb adder
Only want the space and not the tempo change? Leave speed at 100%, push the wet mix up, and pick a larger space. The tempo stays exactly where it was.
100% · 70% wet · Cathedral
Who it’s for
What people use a slowed reverb maker for
TikTok, Reels and Shorts editors
Load the clip, hit TikTok Classic, export MP3, and drop it straight into CapCut or Premiere. Faster than rebuilding speed and reverb as two separate steps for a one-off post.
Lofi study and night playlists
Lofi Chill keeps vocals intelligible while adding distance — 85% speed with a lighter Room reverb, so a playlist can run for hours without turning to mush.
Vloggers and ambient editors
Dreamy pushes the wet, spacious sound people associate with slowed edits. Export WAV, then encode for video so the reverb tail survives the compression.
Ballads and sad-song edits
Slower speed, more space, optional lighter low end on a track you bring yourself. Process audio you have the rights to use — we do not host or link copyrighted downloads.
Practice and key-locked slowdowns
Pitch-locked mode slows the tempo without moving the key, which is what you want when the point is to play along in the original key rather than to make an edit.
Nightcore flips and mashups
Take the same file up to 130% with a light reverb wash, then layer it against the slowed version for a two-part edit from one upload.
Formats
Speed, formats and limits
We accept MP3, WAV, FLAC, M4A, AAC and OGG up to 100 MB, one file at a time, and export WAV as 16-bit PCM or MP3 at 192 kbps. Speed runs from 50% to 150% and reverb wet from 0% to 100%. Decoding, stretching, reverb and encoding all happen on your device, so a long file is limited by your machine rather than an upload queue.

Sounds right
- Slowed edits between 70% and 85% — the range behind most viral versions
- Reverb on its own with the speed left at 100%
- Loops, stems and demos of a few minutes, where the render is quick
Fast render
A quick pass for checking the vibe before you commit. Fine for loops, drums and short edits, and the option to reach for when you are still moving sliders.
Best render
A slower offline render that stays cleaner on sustained material — vocals, piano, strings and pads — where smearing is easiest to hear.
The live preview is a real-time approximation of the sound: it plays the track at your speed with the reverb mix applied. Export renders the file properly, with the time-stretch, the impulse-response reverb, the manual pitch and the bass boost all baked in.
You get the file
Free slowed reverb maker, no sign-up.
Slowing, reverbing and downloading are free with no daily cap and no account. Free does not mean “free preview, paid download” here — you get the whole file, as WAV or MP3, with no watermark. Your audio is never uploaded: it is stretched and encoded right in your browser.
FAQ
Frequently asked questions
Presets, pitch, formats and privacy — the short answers.
What is a slowed reverb maker?
A tool that takes audio you own, lowers the playback speed and adds reverb so the track gains space and distance. Classic viral edits drop the pitch at the same time, which is where the tape-style quality comes from — here that is Classic pitch mode, and Pitch locked keeps the key instead.
What is the difference between a slowed reverb maker and a slowed + reverb generator?
Nothing — they are the same tool. Maker, generator and converter all describe slow-speed-plus-reverb processing, and this page does all of it in one browser session.
Does slowing a song down change the pitch?
In Classic mode, yes: speed and pitch move together, tape-style, which matches most viral slowed edits. Pitch locked keeps the key untouched for practice-style slowdowns, and Manual lets you set the shift yourself within ±4 semitones.
Which preset should I start with?
TikTok Classic if you want the sound people hear in short-form edits. Lofi Chill for study playlists. Dreamy for vlogs and ambient. Nightcore when you want the sped-up flip. Every preset stays editable — move any slider and the tool switches to Custom.
Do the manual pitch and bass boost show up in the preview?
Speed, reverb and space update live as you drag. The manual pitch offset and bass boost are applied when the file is rendered, so export a short test or trust the settings once you know the preset — the preview is a fast approximation, the download is the real render.
Why does my slowed version sound muddy at 60% or lower?
The more a track is stretched, the more any time-stretch engine smears transients. Stay around 70–85%, start from a WAV if you have one, and lower the reverb wet rather than raising it when you also drop the speed.
Can I slow down just part of a song?
Not yet — the current flow processes the whole file. Trim the section you want in your editor first, then run it through the maker.
Can I use a YouTube or Spotify link?
Not directly. YouTube’s built-in speed control cannot add reverb and cannot export a processed file. Bring audio you have the rights to use, then upload it here.
Is there a file size or format limit, and does it work on mobile?
MP3, WAV, FLAC, M4A, AAC and OGG up to 100 MB per file, one file at a time — and yes, the page runs in mobile browsers on both Android and iPhone, with preview and export on your device. Long files are simply faster to render on a desktop.
Is it free? Does it add a watermark?
Yes — free, with no account and no watermark on the exported file. Nothing is uploaded, so there is no copy of your audio to delete afterwards.
