About the Slowed and Reverb Maker

The Slowed and Reverb Maker turns any song into the dreamy, slowed-down edit style popular on TikTok and YouTube. Slowing the playback also lowers the pitch — that deeper, hazier sound is the signature of the genre — and a layer of echo-based reverb adds the spacious, underwater atmosphere.

You control both parts: a speed slider from a subtle 95% down to a heavy 75%, and a reverb depth slider from dry to drenched. The classic 'slowed + reverb' sound sits around 85% speed with moderate reverb, which is the tool's default.

Everything is processed 100% locally in your browser with WebAssembly ffmpeg. Your music never leaves your device, there are no watermarks, and you can remake the edit with different settings as many times as you like.

Frequently asked questions

Why does slowed audio sound deeper?

This tool slows the song the classic way — by stretching the samples — which lowers the pitch along with the tempo, exactly like slowing down a vinyl record. That pitch drop is intentional: it is the defining sound of the slowed + reverb style.

What speed do most slowed and reverb edits use?

Most popular edits sit between 80% and 90% of the original speed, with 85% being the sweet spot — noticeably slower and deeper without becoming muddy. The default settings match that classic sound.

Can I slow a song down without changing the pitch?

Yes, but not with this tool — that is a different effect. Use the Change Audio Speed tool, which keeps pitch constant while changing tempo. Combining it with this tool's reverb-only setting (100% is not offered here, so slow minimally) is not the intended workflow.

Is it legal to post slowed and reverb edits?

The edit still contains the original copyrighted recording, so posting it publicly generally requires the rights holder's permission, and platforms may claim or remove it. Making edits for personal listening is not an issue.

Is my song uploaded to a server?

No. The whole edit is rendered in your browser using WebAssembly ffmpeg. Nothing is uploaded, which also means there is no queue and no file size paywall.
