Expressive Audio Generator AUv3

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!

"It’s striking to me that auGEN X pulls off the feat of being just as valuable as a professional testing tool for software and hardware as it is for music creation/sound design. In practice, the real testament to its usefulness for me is that I find myself firing it up constantly, for more and more purposes."
