IVGI
Key Features
- Analog saturation algorithms shared with the paid SDRR plugin, delivering tube and tape-style harmonic coloring
- Controlled Randomness engine modulates all internal processes to emulate authentic analog drift and variance
- Asym Mix control adjusts signal symmetry for transparent or compressed saturation without altering harmonic content
- Response knob shifts frequency emphasis from low-end warmth (LF+) through neutral to tape-like high-frequency smoothing (HF+)
- Modeled stereo crosstalk with adjustable level from -90 dB to -60 dB adds subtle inter-channel bleed for realistic stereo imaging
- 4x oversampling with near-zero aliasing at only 7 samples of latency
- Accurate VU metering with input, output, and unique RMS output-input difference mode for easy level matching
Description
IVGI by Klanghelm is a saturation and distortion plugin built on the same analog modeling algorithms as the paid SDRR. It delivers everything from delicate harmonic warmth on the master bus to aggressive, gritty distortion on individual tracks, all while reacting dynamically to the input signal.
The plugin's Controlled Randomness engine modulates every internal process to simulate the drift, variance, and fluctuations found in real analog circuitry. This gives the saturation an organic, living quality that static digital processing cannot match.
Five intuitive controls shape the character of the effect. The Drive knob sets the saturation intensity, the Asym Mix control adjusts signal symmetry to move between compressed saturation and a more transparent result, and the Response knob shifts frequency emphasis from low-end warmth to tape-like high-frequency smoothing.
Stereo tracks benefit from modeled crosstalk behavior that adds subtle inter-channel bleed at levels as low as -90 dB. The plugin runs at 4x oversampling with virtually no aliasing, even at extreme drive settings, and introduces only 7 samples of latency.
IVGI is internally calibrated to 0 VU equals -18 dBFS, with an accurate VU meter that monitors input, output, and a unique RMS difference mode for easy gain-matched A/B comparisons. Users consistently praise it for adding character and density that rivals paid saturation tools, making it a staple on mix channels where tonal quality matters most.

Tips
- Use the Drive knob to add subtle warmth or intense distortion depending on the needs of your track.
- Adjust the Asym Mix control to achieve a more transparent or compressed sound.
- Utilize the X-Talk control to add a realistic stereo crosstalk effect, enhancing the depth of your mix.
- Set the Trim control to ensure your input signal hits around 0 dBVU for optimal performance.
- Experiment with the Response control to focus the saturation on different frequency ranges, such as adding warmth to the low end or brightness to the high end.
- Monitor the VU meter to keep track of your input and output levels, ensuring a balanced mix.
- Apply IVGI on the master bus for subtle saturation that glues the mix together, or on individual tracks for more pronounced effects.
Frequently Asked Questions
How does IVGI compare to Klanghelm's paid SDRR plugin?
IVGI uses the same core saturation algorithms as SDRR's DESK mode, delivering identical sound quality for that particular saturation style. SDRR adds three additional saturation modes (TUBE, FUZZ, and RECTIFY), multi-stage processing, and more detailed controls, but IVGI covers the most versatile single mode with a simplified interface.
What is the Controlled Randomness feature and should I turn it up?
Controlled Randomness modulates every internal process to simulate the drift and variance of real analog circuits, giving the saturation an organic feel. At moderate settings it adds subtle liveliness without being noticeable; at higher settings the modulation becomes audible and contributes to a vintage, lo-fi character.
Can IVGI be used on the master bus for mastering?
Yes, IVGI excels at gentle master bus saturation when the Drive is kept low and Asym Mix is pushed toward maximum transparency. It is internally calibrated to 0 VU at -18 dBFS, which is standard mastering gain staging. Some users prefer it on individual channels since the effect can become aggressive quickly at higher drive settings.
What does the Response control actually do?
The Response control changes how saturation affects different frequencies. In LF+ mode, low frequencies are emphasized and highs are gently cut, adding bass warmth. In HF+ mode, high frequencies are saturated and compressed more, producing tape-like smoothing with an ultra-smooth high shelf filter to recover brightness.
