Singing

SingFun is a pocket audio toy. Hit the big red key, say or sing anything, then hear it backwards, squeaky, slow-mo, looped or boomeranged — instantly.

For iPhone & iPad

SingFun main screen: four slots, waveform, Record, Play and Reverse keys — Record, Play, Reverse

Playing a loop with pitch raised and reverb on — Loop it, pitch it, drown it in reverb

Reverse playback of a trimmed region with Boomerang on — Trim a bit and boomerang it backwards

Slot menu with Download Normal, Download Reverse and Delete — Download any take — forward or reversed

An empty slot with one big Record key — Empty slot? One big red key.

Four slots, zero setup

Record into numbered slots and jump between them. Trim the bit you want with two handles.

Backwards, for real

Reverse actually plays the sound backwards — try saying a word and learning to say it in reverse.

Pitch · Speed · Reverb

Chipmunk or monster, half speed or 4×, dry or cathedral — tweak live while it plays.

Loop & Boomerang

Loop a snippet or ping-pong it forwards and backwards. Download any take as a WAV.
