What Is Slowed Reverb?
Slowed reverb is an audio editing style where a song is slowed down, the pitch becomes deeper, and reverb is added to create a wide, dreamy, late-night sound. The effect is used for TikTok edits, YouTube uploads, study playlists, sad songs, phonk edits, and vocal remixes because it makes familiar music feel slower, warmer, and more atmospheric.
This slowed reverb generator does the full job in one place: upload audio, set speed, add reverb, adjust pitch and bass, preview the edit, and export MP3 or WAV.
Fast workflow
How to Make a Slowed Reverb Song Online
1
Upload your audio file
Choose an MP3, WAV, FLAC, or OGG file from your device. Your audio is processed locally in your browser instead of being uploaded to a server.
2
Start with the clean slowed reverb preset
Use 0.85x speed, 42% reverb, 2.8s room size, +1 pitch, and +3 dB bass as the safest first setting for most songs.
3
Preview the chorus
The chorus or loudest section reveals muddiness, clipping, and vocal darkness faster than the intro. Adjust one control at a time.
4
Export MP3 or WAV
Download MP3 for sharing on TikTok, YouTube, Instagram, or messaging apps. Choose WAV when you want a lossless file for another editor.

Best Slowed Reverb Settings by Song Type
The best slowed reverb sound is not the wettest sound. Start with a clean balance, then push the mood. These settings target TikTok slowed reverb, vocal slowed reverb, sad song edits, bass boosted slowed reverb, and clean MP3 exports.
| Use Case | Speed | Reverb | Decay | Pitch | Bass | Why |
|---|---|---|---|---|---|---|
| Classic slowed reverb | 0.85x | 38-42% | 2.5-3.0s | +1 semitone | +3 dB | Best starting point for most pop, R&B, indie, and playlist edits. |
| TikTok slowed reverb | 0.80-0.85x | 40-48% | 3.0-4.0s | +1 semitone | +4 dB | Keeps vocals clear after TikTok, Reels, or Shorts compression. |
| Clean vocal slowed reverb | 0.85-0.88x | 30-36% | 2.0-2.6s | +1 to +2 semitones | +2 dB | For songs where lyrics matter and muddy reverb would bury the hook. |
| Sad / deep slowed reverb | 0.78-0.82x | 40-45% | 3.2-4.5s | 0 to +1 semitone | +3 dB | Darker, slower, and more atmospheric without pushing decay too far. |
| Bass boosted slowed reverb | 0.82-0.86x | 25-35% | 1.8-2.5s | 0 semitones | +5 to +7 dB | Better for phonk, 808s, car audio tests, and headphone bass edits. |

Quality fixes
How to Make Slowed Reverb Sound Good
Most bad slowed reverb edits fail for the same reasons: too much wet mix, too long a decay tail, or too much bass after slowing. Fix those before downloading your MP3 or WAV.
My slowed reverb edit sounds muddy
Reduce reverb wet mix to 30-38%, shorten decay to 2-3s, and preview the chorus. Too much low-mid reverb is the usual cause.
The vocal became too dark
Raise pitch by +1 or +2 semitones after slowing. This keeps the slowed feel while restoring intelligibility.
The bass distorts after export
Lower bass boost first, then lower wet mix. Distortion usually comes from boosted low-end peaks, not the file format.
The edit sounds weak on phone speakers
Use 0.82-0.85x speed, 40% wet, 3s decay, +1 pitch, and +3 to +4 dB bass. Phone speakers need tighter reverb.

How Our Browser Audio Processing Works
- Audio is decoded and processed in your browser.
- Your file stays on your device instead of being uploaded for processing.
- Speed changes the tempo and pitch relationship of the song.
- Reverb is shaped with wet/dry mix and decay time.
- Bass boost increases low-frequency energy, so smaller boosts are cleaner.
- Export MP3 for sharing or WAV for editing in another audio app.
Responsible Audio Editing Note
Slowed reverb edits do not remove copyright. For public or commercial use, use music you own, music you have licensed, or royalty-free audio. For context, read the slowed reverb history and culture guide and the slowed reverb copyright guide.
Creators ask — opinions, not specs
Taste Questions From the Community
These answers are editorial takes on style, not fixed technical rules — the factual settings live in the FAQ below.
?Is 0.85x always the best speed?
In our experience it's the safest starting point, not the best ending point. Ballads often feel richer near 0.80x, while busy pop mixes hold together better at 0.86–0.88x. If the vocal starts slurring, you went too far.
?Long dreamy reverb tail or short clean one?
We lean short. Long tails sound impressive on headphones for the first chorus, then fatigue the ear and smear the mix on phone speakers. A 2.5–3s decay usually ages better than a 5s cathedral wash.
?Should the pitch stay lowered or be corrected up?
Split opinion among editors: the untouched deep pitch is the classic DJ Screw lineage, but +1 semitone of correction keeps modern vocals intelligible. We default to +1 for lyric-driven songs and 0 for instrumentals.
?Is slowed reverb played out in 2026?
The lazy version is — a random song at 0.8x with maxed reverb adds nothing. Edits that still travel are intentional: preset tuned to the genre, tasteful bass, and a section choice that fits the mood of the clip.
Slowed Reverb Generator FAQ
Q:What is a slowed reverb generator?
A slowed reverb generator is a free online audio tool that slows down the tempo of a song, lowers its pitch, and adds spacious reverb to create a dreamy, atmospheric edit.
Q:How much should I slow a song for slowed reverb?
For the classic slowed and reverb effect, slow the speed to between 0.82x and 0.88x of the original tempo. This range deepens vocals and increases the spatial feel without losing the song's melody.
Q:What reverb setting should I start with?
A good starting point is 30% to 45% reverb wet mix and 2 to 4 seconds of decay. Preview the loudest section and reduce reverb if vocals start to sound muddy.
Q:Can I make slowed reverb songs on mobile?
Yes. Our slowed reverb maker works directly in mobile browsers on iOS and Android. You can upload audio files, adjust sliders, preview instantly, and download your edits.
Q:Does this tool upload my audio?
Audio processing runs in your browser instead of being uploaded to a server. Keep your original files on your own device and only edit audio you own or have permission to use.
Q:Can I download the edited song?
Yes. After previewing the result, you can export the slowed song to your device as an MP3 or WAV file.
Q:What file types are supported?
Our generator supports uploading common audio files such as MP3, WAV, FLAC, and OGG. You can export your processed tracks as MP3 or WAV.
Q:Is slowed and reverb the same as nightcore?
No. Slowed and reverb slows the speed and lowers the pitch of a song to make it relaxed and atmospheric. Nightcore speeds up the tempo and raises the pitch to create high-energy tracks.
Q:What is the difference between slowed reverb and just slowing a song?
Slowing a song only changes playback speed and pitch. Slowed reverb adds a spatial effect that simulates room reflections. The reverb tail creates the signature dreamy, atmospheric quality.
Q:Why does my slowed reverb edit sound muddy?
Muddiness usually comes from too much reverb wet mix or too long a decay on bass-heavy tracks. Reduce wet mix to 30-35%, decay to 2-3 seconds, and preview the loudest section again.
Q:What is the best slowed reverb preset for vocals?
For clear vocals, keep wet mix under 40% and decay under 3 seconds. If the voice becomes too dark, nudge the speed up rather than reaching for pitch — speed and pitch share one playback rate here, so adding semitones speeds the track up as well as brightening it. The clean slowed reverb preset is a safe starting point.
Q:How do I make slowed reverb sound like the TikTok trend?
TikTok slowed reverb typically uses 0.80x to 0.85x speed, 40% to 50% reverb wet mix, 3 to 4 seconds of decay, and a small bass boost so it survives phone speakers and platform compression.
Q:Can I add bass boost to my slowed reverb edit?
Yes. Adding +2 to +4 dB of bass boost can restore warmth after slowing a track. Apply bass boost after setting speed and reverb, then preview the loudest section to avoid distortion.

What Is a Decibel? Why +6 dB Means Double and Nothing Means Anything Alone
A decibel is not a quantity. It is a comparison, and it is logarithmic — which is why +6 dB doubles the amplitude, why 0 dBFS is the ceiling rather than silence, and why a number with no reference attached tells you nothing.
