A different approach of an audio oscillator app!

auDSPr, a new developer for iOS apps, recently released auGEN X, a new versatile Oscillator app. This is not just a classic oscillator but more a sound design app. auGEN X features an audio oscillator, a noise and an impulse generator.

Good to see that the app comes in the initial version with AUv3 support that allows you to use the app in multiple instances.



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!
