How to Make a Slowed and Reverb Song Online — 3 Simple Steps
No software, no account. Your audio never leaves your device.
- 01
Upload Any Audio or Video File
Drop in an MP3, WAV, FLAC, AAC, OGG, or M4A — or even a video like MP4, MOV, or MKV. The slowed and reverb generator decodes the audio track instantly in your browser, so nothing is ever sent to a server.
- 02
Pick a Preset or Dial In Your Sound
Tap Slowed for the classic 0.85x speed + reverb formula, Nightcore for a sped-up remix, or open Vibe Match for 15+ one-tap aesthetics like Night Drive, Sad Edit, and Phonk Drift. Fine-tune Speed, Reverb, Timbre, and Bass Boost per segment.
- 03
Preview & Export Your Edit
Press Play to hear your slowed + reverb mix in real time — the animated waveform even reacts to your vibe. Split the track to apply different effects to different parts, then export as WAV, MP3, or AAC and download instantly.
Why Use This Slowed + Reverb Generator?
One-tap presets, per-segment editing, and pro-quality export — free, in your browser.
One-Tap Slowed + Reverb
The Slowed preset instantly applies the signature slowed and reverb formula — playback at 0.85x speed blended with a lush hall reverb and a gentle bass lift. It's the exact sound behind millions of viral slowed reverb edits, recreated in one tap.
Nightcore & Sped-Up Mode
Flip the vibe with the Nightcore preset: 1.25x speed with a dry, punchy signal — the classic nightcore formula for sped-up remixes and TikTok sounds. Drag the Speed slider anywhere from 0.5x to 1.5x for custom sped-up or ultra-slowed versions.
15+ Vibe Match Presets
Not sure where to start? Vibe Match auto-tunes your track into aesthetics like Night Drive, Sad Edit, Dreamcore, Space Reverb, and Phonk Drift. Each vibe retunes speed, reverb, and bass — and repaints your waveform in its own animated color theme.
Split Songs Into Segments
Slowed reverb on the chorus but not the verse? Split your track at any timestamp with + Split, then apply different speeds, reverbs, and vibes to each part. Every segment previews live and exports as one seamless, continuous file.
100% Private — No Server Uploads
All decoding, slowing, reverb processing, and exporting happens entirely on your device with the Web Audio API. Your unreleased tracks and edits are never uploaded anywhere, keeping everything completely private.
Export as WAV, MP3, or AAC
Render at full quality and pick the format that fits: WAV for lossless, editing-ready output, MP3 for universal sharing, or AAC for high-fidelity streaming. Your slowed + reverb export downloads immediately — no queue, no watermark.
