auGEN X: The New iPad Audio Generator

At Profusion we are dedicated to providing you with the latest audio updates via our newsletter, and thought you might be interested in auGEN X, a precision audio generator from auDSPr and David Simpao, the creator of the Nemesis NemFX chip:

Indie audio app developer auDSPr has created auGEN X – a Precision Audio Generator for iPad. Use auGEN X to help set up, test, calibrate, and optimize your audio system. 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.


Oscillator for creating tone signals

  • 3 Modes: Fixed, Frequency Sweep, or Level Sweep
  • 4 Wave Shapes: Sine, Triangle, Rectangle, and Saw
    • Triangle and Rectangle have a Duty Cycle control (1.0% to 99.0%)
    • Triangle, Saw, and Rectangle are alias-suppressed yielding virtually alias-free performance at musical fundamental frequencies
  • 10 Hz to 20,480 Hz extended audio frequency range (great for testing subwoofers!)
  • Full-featured Frequency or Level Sweep with 5 Sweep Types, settable Sweep Direction, and selectable Repeat or 1-Shot Mode
    • Sweep Period has an extremely wide range from 1/10,000th of a second to 100 seconds and can alternatively be set as a Sweep Rate in Hertz or BPM
      • Wide sweep range allows for FM and AM style sounds

Noise Generator

  • 2 Modes: Fixed or Level Sweep
  • White Noise or Pink Noise
    • Pink Noise conforms to SMPTE Standard 2095-1:2015 Calibration Reference Wideband Digital Pink Noise Signal

Impulse Generator 

  • Useful for checking the response of reverb algorithms
  • Impulse Width can be set in samples

Works either as a Stand-Alone App or as an AUv3 Audio Unit Extension

  • As a Stand-Alone App audio is sent to the iPad’s built-in speakers, the Headphone/Line Output, or to any iOS-compatible USB audio interface connected to the Lightning jack
  • Verified to work great in AUv3 Host Apps such as GarageBand, AUM, apeMatrix, Cubasis, BeatMaker 3, and Auria Pro

Technical Specifications

  • Audio signal path uses state of the art Double Precision 64-bit Floating Point for maximum accuracy
  • Stereo output
    • Selectable Pan Laws include Linear Panning and Constant Power Panning
  • Supports 44.1, 48, 88.2, and 96 kHz sample rates
  • User Guide embedded in App — no internet connection required to read it

System Requirements

  • Compatible with iOS 9.0 and up (iPad 2, iPad mini (1st Generation), and up)
    • Support all the way back to iOS 9 means auGEN X works on every iPad model (except the original first generation iPad).  Breathe new life into your old iPad 2 by using auGEN X to make it a dedicated, precision audio test machine.
  • AUv3 Audio Unit Extensions are supported on iPads (iPad 4, iPad mini 2, and up)

iOS-compatible USB audio interface connected to the Lightning jack required for 88.2 and 96 kHz sample rate
