Wah-Wah Controller
Control VST/AU with your lips
If you’re looking for a way to control your external AU/VST plug-ins, you can now use the iPhone front-facing camera as an "expression pedal" with facial expressions!
It uses TrueDepth face tracking technology from Apple, which allows to control VST effects using your mouth with near-zero latency.

It’s not only fun, but a valuable tool for work.
The app is available in the App Store.
