auGEN X bridges the creative musical world of artists with the exacting scientific world of audio engineers. What started as a precision audio test utility has grown into a fun experimental sound design instrument. On one end use auGEN X to help set up, test, calibrate, and optimize your audio system. On the other 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 responding to MIDI In and BPM Sync from Hosts. 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. auGEN X has expanded into a musical tool for exploring and learning sound design. Our goal is for auGEN X to be an Essential in your audio toolbox. We hope you enjoy it and we’re excited to hear the cool things that you do with auGEN X!
