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!

About

Ringotron

This app offers advanced control over ring modulation effects for sound design and audio processing. Its multi-band design allows precise manipulation of the audio spectrum, with a special soft mode to reduce unwanted intermodulation. It can also function as a resonant filter that smoothly transitions into a ring modulator.

Highlights
  • Parallel ring modulator units
  • Stereo separation control
  • Ultra-narrow band resonance
  • Ribbon controls for frequencies
  • Modulation system for band centers
  • Tempo syncing for oscillators
  • Soft limiter and clipper
Features
Read full description

Ringotron allows taming the strong transformational effects of traditional ring modulation, opening up a wider range of possibilities in sound design and audio FX. Its multi-band design enables fine control over which parts of the spectrum will be transformed by the effect. A special soft mode is available that borrows concepts from feedback modeling, which can be used to reduce intermodulation effects that are often a limiting factor in the more general applicability of ring modulators. In addition to the layers of control they provide, combination of these core features also allows the plugin to act as a stereo, multi-peak resonant filter that can also smoothly morph into a ring modulator. FEATURES: • 2 parallel ring modulator units (max. modulator frequency: 8 kHz) • Stereo separation can be added to band center, mod. frequency, mod. phase • Ultra-narrow bands can be used to create highly resonant sounds • 4 large ribbon controls for band center and modulator frequencies • Band center frequencies can be modulated by the built-in modulation system • Tempo syncing can be independently configured for each oscillator • Built-in soft limiter and clipper to protect against volume spikes IMPORTANT INFORMATION: The plugin comes with a zero-latency, non-brickwall soft limiter, and as such, its stopping power is limited. Make sure to always leave enough headroom or use an external brickwall limiter for total protection against powerful transients. Alternatively, a built-in soft clipper is also available. PLEASE NOTE: • AUv3-compatible host app is required • Suported sampling rates: 44.1, 48, 96 kHz
