Musical for artists. Precise for scientists. Easy and FUN for everyone.

"I really see this app becoming a standard and a must have component in one's iOS audio app arsenal."

Paul Henry, Paul Henry Pro Audio

Indie audio app developer auDSPr has created auGEN X. You can think of auGEN X in two ways: first, it is a precise tool for making audio test sounds, and second, it is a performable creative sound design instrument. On one end use auGEN X to help set up, test, calibrate, and optimize your audio system. On the other end use it to create a wide variety of interesting sounds. auGEN X has a full-featured audio oscillator, a high quality noise generator, and an impulse generator. The simple yet powerful user interface is designed for fast, precise, intuitive control over your signals. auGEN X works both as a Stand-Alone App and as an AUv3 Audio Unit Extension.

I started making this App because as an audio electronics engineer I could not find a single audio generator that does everything that I require AND is an AUv3 Audio Unit. It has developed into a cool tool for exploring sound design. Our goal is for auGEN X to be one of your Essentials in your audio toolbox. We hope you enjoy it and we’re excited to see and hear the cool things that you do with auGEN X!
