Frequently Asked Questions
How do I make a song slowed and reverb?
Upload an audio file, then lower the speed (around 0.85x gives the classic slowed feel) and raise the reverb to taste. Preview it, and when you like it, download the slowed + reverb version. Everything runs in your browser — nothing is uploaded.
Is the slowed and reverb generator free?
Yes, completely free with no signup. You can process songs, adjust the speed and reverb, and download the result at no cost.
Does slowing the song also lower the pitch?
Yes — like the classic slowed + reverb sound, lowering the speed also lowers the pitch, giving that deeper, dreamier tone. That's the signature of the effect.
Will my audio be uploaded anywhere?
No. The slowed + reverb processing happens entirely in your browser using the Web Audio API. Your file never leaves your device, so it stays private.
What audio formats are supported?
MP3, WAV, M4A, AAC, OGG, and FLAC — any format your browser can decode. The processed slowed + reverb track downloads as a WAV file.
