Make slowed + reverb remixes in your browser
Slowed + reverb is one of the biggest remix styles on YouTube and TikTok — slow a track down, bathe it in reverb, and it turns dreamy, nostalgic, and atmospheric. Producers, editors, and fans use it to reimagine familiar songs, score late-night drives, or back aesthetic montages. This maker does the whole thing in your browser: drag in any audio, dial in speed and reverb (plus pitch, bass, and echo if you want), preview live, and download.
Pick a one-click preset to start — Slowed + Reverb for the classic vibe, Nightcore for a fast high-energy flip, Daycore for a low slow version, or Sped Up. Then fine-tune with the sliders. Everything runs locally with the Web Audio API (playbackRate for varispeed, a convolver for reverb, a low-shelf filter for bass, and a delay for echo), so your file never leaves your device. Download as MP3 for TikTok and YouTube, or WAV for lossless.
A note on usage: slowed + reverb edits are fun and widely shared, but the original song still belongs to its creator. For public posts on TikTok, YouTube, or Instagram, follow each platform's copyright rules and only use material you have the rights to — your own recordings, royalty-free tracks, or songs licensed for reuse.

Slowed + reverb slows the track down and adds lush reverb for a dreamy, nostalgic feel. Nightcore does the opposite — speeds it up and raises the pitch for a high-energy, upbeat vibe. We have one-click presets for both (plus daycore and sped up).
The Speed slider uses varispeed — it changes tempo and pitch together, like slowing a vinyl record. That combined effect is the classic slowed + reverb sound. Use the Pitch slider to nudge it further, or the presets to get a known vibe instantly.
