Slowed and reverb is a music remix style that took over YouTube, TikTok, and SoundCloud. By lowering the speed and pitch of a song and adding deep, atmospheric reverb, you get a dreamy, nostalgic version that feels completely different from the original. It originated from DJ Screw's chopped and screwed technique in Houston hip-hop and has since evolved into a global internet phenomenon covering pop, R&B, lo-fi, and even classical music.
Our slowed and reverb generator lets you create this effect in three simple steps: upload your audio file (MP3, WAV, M4A, OGG, or FLAC), adjust the speed and reverb sliders to taste, then hit export. All processing runs locally in your browser using the Web Audio API — your files never leave your device. No signup, no download, no waiting for server queues.
The default preset — 0.80x speed with 45% wet reverb and a touch of bass boost — is your sweet spot for that classic slowed reverb sound. But you can go further: dial the speed down to 0.50x for an ultra-slowed ambient wash, or push it up to 1.25x for a Nightcore-style remix. The tone control lets you muffle the highs for a warmer, lo-fi character, while the room size slider adjusts the reverb from a tight studio room to a cavernous hall.
Once you are happy with the preview, export your track as MP3 (128kbps) for free. Pro subscribers get lossless WAV exports, 320kbps MP3, and no watermark — perfect for DJs, producers, and content creators who need the best quality. Whether you are making slowed reverb edits for your YouTube channel, creating a TikTok sound, or just vibing to your favourite songs in a new way, this tool has you covered.

Frequently asked questions
- What is slowed and reverb music?
- Slowed and reverb is a remix technique where a song's playback speed is reduced (typically to 0.70x–0.85x) and heavy reverb is applied. The result is a dreamy, atmospheric version of the original. The style became massively popular on YouTube and TikTok, where slowed reverb edits of pop, R&B, and hip-hop tracks regularly rack up millions of views.
- Is this slowed and reverb generator really free?
- Yes! You can use the full tool, preview in real-time, and export MP3 files at 128kbps completely free — no signup required. If you need higher quality (lossless WAV, 320kbps MP3, no watermark), our Pro plan is $6/month.
- Do my audio files get uploaded to a server?
- No. All audio processing happens locally in your browser using the Web Audio API. Your files never leave your device. We cannot see, access, or store your music.
- What file formats are supported?
- You can upload MP3, WAV, M4A, OGG, and FLAC files up to 50MB. Export is available as MP3 (free) or WAV and 320kbps MP3 (Pro).
- Can I use the exported audio for my YouTube or TikTok videos?
- Absolutely. Once you export your slowed reverb version, it is your file to use as you wish. Just be mindful of the original song's copyright — creating a slowed reverb edit does not override the underlying copyright.
