Slow Down or Speed Up Audio Online — Free, Private, No Sign-up

SnipSound's Slowed + Reverb Maker turns any song into that dreamy, slowed-down sound with a reverb tail — the aesthetic all over TikTok, YouTube, and SoundCloud — right in your web browser. Drop in an MP3, WAV, OGG, FLAC, AAC or M4A, click the Slowed + Reverb vibe (or fine-tune the speed and reverb yourself), preview it live, and download. The reverb is baked into the file. Nothing is uploaded — it's 100% private and there's no watermark.

Prefer a sped-up nightcore edit, or just need to slow audio down without reverb? The same engine powers our Audio Speed Changer, with one-click Nightcore and Sped-Up vibes plus the full 0.25×–4× range.

Why use SnipSound

Frequently Asked Questions

How do I slow down or speed up audio online?
Drop your audio file onto the page, drag the speed slider (or click a preset like 0.5x or 1.5x), preview the result, and download. Everything runs in your browser.
How do I make a slowed + reverb song?
Drop your audio in, click the Slowed + Reverb vibe (or set the speed near 0.8× and raise the Reverb slider), preview, and download — the reverb is baked into the exported file.
How do I make a nightcore / sped-up version?
Click the Nightcore vibe — it speeds the track to ~1.3×, which also raises the pitch for that classic nightcore sound. Tweak the speed slider to taste, then download.
Does the pitch change when I change the speed?
Yes. This tool uses simple resampling, so slowing down lowers the pitch and speeding up raises it — the classic “tape effect”. Pitch-preserving (time-stretch) mode is on the roadmap.

No. All processing happens entirely in your browser via the Web Audio API. See our privacy policy.
What formats are supported?
Any format your browser can decode — MP3, WAV, OGG, FLAC, AAC, M4A, and more.
