Distort ~ Distortion Audibility Tester
DISTORT was conceived as a tool to allow one to apply a combination of complex distortions to any recorded signal, including music and hi-res recordings. DISTORT also provides simple visualization tools to examine the effects of all the distortions as they are being adjusted. The distorted sound file can be played through the available audio device drivers, from ASIO to WASAPI to Direct Sound.
The following distortions are currently provided with a variety of settings and options:
- Harmonic distortion (THD, SINAD, THD+N)
- Different noise floors and various spurious noise components, such as mains frequency
- Various types of jitter, random, correlated, 1/f noise, and at various frequencies
- Dynamic range compression effects
- Different types of dither and bit settings

IVGI ~ Saturation & Distortion
IVGI can deliver very soft and subtle saturation, that feels at home on the master buss. It is equally capable of very dense and dirty distortion effects to spice up single tracks.
IVGI reacts dynamically to the input signal. Even the modeled fluctuations react dynamically and also change depending on the drive setting, so that it doesn’t get in the way of the SOUND. Stereo tracks benefit from it’s modeled crosstalk behavior.IVGI features a Controlled Randomness, which determines the internal drift and variance inside the unit. It contributes to the liveliness and realness of IVGI’s saturation character. To achieve this, all internal processes are modulated to some extent.
IVGI gives you a sensible amount of controls to manipulate the character of the saturation itself. It offers a unique ASYM MIX knob to alter the symmetry of the signal without affecting the harmonic content much.
IVGI also lets you alter the frequency dependency of the saturation with the RESPONSE control.

- Designed with dynamic response that changes according to the input level – Much more than just a basic “sample in, sample out”
- Up to 12x Internal Oversampling, separate controls for live/online and off-line render
- Multi-Band EQ – low, mid, high, contour, presence
- Built-in custom convolution-based cab-mic effect, works with almost any sample rate and/or audio buffer size
- New version of C120 has less clutter in GUI, separate page for advanced features
- No commercial bloat!
