Slowed and reverb, without uploading anything
Drop in any mp3, wav, m4a or flac and shape it live: slow the tempo down for that classic slowed sound, layer in reverb for space and depth, or push the bass for more weight. This is browser-based slowed + reverb with no signup — speed and pitch sit on separate faders, so you can change pitch and speed separately, entirely online, in this tab. Slow a track down and dial the tone back to keep the pitch you started with, or lean into the pitch drop for a different mood. Every fader updates the sound instantly while it plays: nothing is uploaded to a server, and nothing is processed until you hit play. When you're happy with the mix, download it as a lossless WAV or a compressed MP3.
Frequently asked questions
- What is slowed + reverb?
- A remix style where a track is slowed down and washed in reverb, giving it a hazy, underwater, nostalgic feel. This editor lets you dial in the speed, pitch, reverb and bass yourself and hear the result change live, instead of downloading someone else's fixed version.
- Does this upload my audio anywhere?
- No — everything runs locally in your browser. There's no server, no upload queue and no account; the file you drop in never leaves your device.
- Can I slow a song down without making it sound lower / chipmunked?
- Yes. Slowing playback down naturally drops the pitch too — that's the classic tape-style slowed sound — but the pitch fader runs independently of speed, so you can nudge it back up to keep the pitch you started with, or push it further for a more dramatic effect.
- What's the difference between slowed + reverb, daycore and nightcore?
- Nightcore speeds a track up and raises the pitch for a brighter, more energetic feel. Daycore and slowed + reverb both slow it down and drop the pitch; slowed + reverb adds a heavy reverb wash on top for that hazy, spaced-out texture, while daycore usually stays drier.
- What audio formats are supported?
- Drop in mp3, wav, m4a or flac. Export the result as a lossless WAV or a 192 kbps MP3.
- Can I use this on my phone?
- Yes — it's a normal web page built on the Web Audio API, so it runs in modern mobile browsers the same way it does on desktop, no app install required.
- Is the export lossless?
- WAV export is lossless 16-bit PCM. MP3 export is compressed at 192 kbps if you'd rather have a smaller file.
