Slowed and Reverb Maker
Drop in a song and it loads with the classic slowed + reverb treatment already applied: 0.8× tape-style slowdown with hall reverb. Fine-tune the speed and space on a live waveform, trim the section you want, and export MP3 or WAV. Your music never uploads.

How it works
Load a song
Drop in an MP3 or any audio file. The slowed + reverb preset is applied the moment it loads — press play to hear it.
Tune the vibe
Adjust speed (0.7×–0.9× is the classic zone), swap hall reverb for room or slapback, and add fades. Everything previews live.
Export your edit
Export the full track or just a selection as MP3, WAV, FLAC, M4A, or OGG — rendered on your device.
Frequently asked questions
What makes the slowed + reverb sound?
Two things: a tape-style slowdown (pitch drops with speed — we default to 0.8×) and a large reverb that fills the space between notes. Our preset applies both in one click, and both stay adjustable in the effects rack.
Can I use my edit on TikTok, YouTube, or Spotify?
The tool is format-ready for all of them — export MP3 or WAV and upload anywhere. Whether you're allowed to depends on the rights to the original song: for public posting you need permission from the rights holders, and platforms' content-ID systems recognize slowed versions.
Why does it sound deeper as well as slower?
That's the point — the preset is deliberately tape-style, so pitch falls with speed, which gives slowed edits their signature deep, dreamy character. If you want slower WITHOUT deeper, use the audio speed changer with "Keep pitch" checked instead.
Is my song uploaded to a server?
No. The slowdown, the reverb, the preview, and the export all run in your browser via WebAssembly. Nothing you load here leaves your device.
