SingFun: Reverse Audio Singing

SingFun is the app for the viral online reverse-talking challenge. Record your voice, hear it backwards, then try to imitate that backwards sound. Record your attempt, reverse it — and find out whether it turned back into the original phrase. Spoken or sung, alone or with friends: it is much harder than it sounds, and the results are hilarious.

HOW IT WORKS
1. Tap the big red key and say or sing a short phrase.
2. Tap REVERSE and listen to it backwards. Listen a few times.
3. Pick a new slot, record yourself imitating that backwards sound.
4. Tap REVERSE on your attempt. Does it sound like the original?
5. Switch between the slots to compare, and keep trying until you nail it.

MADE FOR THE CHALLENGE
• 4 recording slots on iPhone, 6 on iPad — the original, your attempts, and your friends' attempts, one tap apart
• True reverse playback: the sound really runs backwards
• Trim with two handles, or tap the waveform to move the nearest handle, so you compare exactly the part that matters
• Big colorful 3D keys, instant response, zero menus — kids get it in seconds
• Download any take as a WAV file, forward or reversed — post your best attempt or send it to someone to decode

BONUS EFFECTS
When you want to mess around some more: shift the pitch from chipmunk to monster, slow it down or speed it up to 4×, add reverb, loop a snippet or boomerang it back and forth — all live while it plays.

PRIVATE BY DESIGN
Your recordings never leave your device. No account, no cloud, no upload — a sound only leaves your phone when you export it yourself.

MADE FOR IPHONE DUO
Open your iPhone Duo and each screen gets its own track. Play both at the same time to compare them side by side.
