Questions
Is this underwater effect free?
Yes, 100% free. No sign up, no watermark and no limits.
Does my song get uploaded?
No. Your song never leaves your device. Everything happens right in your browser, so it stays private and works on unreleased tracks, beats and voice memos too.
How do I make a song sound underwater?
Drop your song in the box and press Play. It starts on the underwater settings: a deep muffle with a watery echo. Adjust, then click Export MP3.
Can I make it sound like surfacing from the water?
Yes. Set Door effect to "Door opens" and it fades from underwater to clear, like coming up for air. "Door closes" is like diving in.
Why does underwater audio sound muffled?
Water blocks high frequencies much more than low ones, so you mostly hear deep, dull sounds with a smeared echo.
What file types can I use?
Any audio your browser can play: MP3, WAV, M4A, FLAC, OGG and more. Save the result as MP3 or WAV.
No sound on my iPhone?
Turn off silent mode (the switch or Action button on the side), turn up the volume, and press Play again. Older iPhones mute web audio in silent mode.
