Immersive In-Ear Mixing with Intuitive Control

Control your KLANG:fabrik and KLANG:vier 3D Immersive In-Ear Monitoring system and build your individual monitor mix for headphones in a 3D space around your head.

Place instruments exactly where you want to hear them. You can adapt what you see with what you hear. Use the app with simple swipe gestures that were developed to be used while performing live on stage. We worked hard to make this app as intuitive as possible.

We provide a demo mode which allows you to test our immersive 3D audio experience.

3D audio is amazing

This software emulation of the hardware boxes is amazing, and will get you hooked on the capabilities of the klang system. I thought it was a gimmick at first, but once you listen, you’ll be converted.

Somehow this app became a problem with my iPhone7. It is constantly locking up my iPhone and causing my battery to drain to nothing. I have spoken with several musicians at our church and they are having the same issues.
