AirSynth enables anyone to make cool musical sounds with their hands!

Using the latest depth sensing camera technology in your device, AirSynth allows you to synthesize music simply by holding your hands in the air.

Combining new technology with vintage sounds, anyone can simulate a theremin for spooky effects.

AirSynth looks great and has a clear, modern UI. It provides a cool real-time visualization of the depth data the camera sees.

Simply start the app, and place your hands above it to control the audio pitch and volume of a range of special voices.

AirSynth supports iPhone® X, XS, XR and iPad Pro. Hand input via depth camera is limited to only devices with the TrueDepth™ camera and FaceID™.

- Control with the movement of your hands
- Futuristic visualization of camera input
- Record your performances to video (New!)
- Choose from a variety of color themes (New!)
- Theremin style option
- Over 5 different voices to play
- Depth control even works in the dark!

It works but I don’t know what to do with it!

It took me sometime to figure out how it works. But it does work. Now that I have tried all the sounds I don’t know what else I can do with the app. I think it will be cool if we get option to record the music or video of playing the sound.

Developer Response ,

Recording is on it’s way for a future update! This should enable recording of the video created, along with the audio and an export for video or just the audio on its own.

I’m also planning to add AudioBus support so it can be connected to other audio apps.

The app now has recording, as of version 1.1, I hope you enjoy!

Thanks a lot,

Deleted & re download fixed problems

The first downloaded this app it never interacted with my camera, I deleted it and downloaded it again and the interface was different as that it now access is my camera and works relatively well. I like the selection of different voices that said I should touch. I haven’t played with it much yet but it is now in working condition.

Developer Response ,

Hi there Erikk. I’m really keen to help troubleshoot this for you, the main test device for this is an Xr so it definitely should be working as intended for you. If you get in touch via I’d be happy to try and help. Thanks, Dave

It is a stunt app

It isn’t a good theremin. It is a wonderful idea, but doesn’t really work. It barely registered my hands and there isn’t much control. You will play with it for five minutes and then you will be done.

But hey, over beers with friends it is a laugh.
