Complex Nonlinearities for Audio Signal Processing

Complex Nonlinearities

This repository contains recent research exploring purely digital complex nonlinear signal processing. Articles explaining the project in further detail can be found on Medium. A technical project overview is available online here.

Each nonlinear effect is available as an audio plugins (VST/VST3/AU). Builds of each plugin are available for Mac and Windows in the Bin/ directory. Linux users can find builds available on the Open Build Service, courtesy of Konstantin Voinov.

Current nonlinearities include:

1. Double Soft Clipper

2. Harmonic Exciter

3. Hysteresis

4. Nonlinear Biquad

5. Nonlinear Feedback

6. Wavefolding

7. Adaptive EQ

8. Nonlinear Allpass

9. Subharmonics Generator

10. Gated Recurrent Distortion

Organization

Each subfolder contains a specific nonlinearity, including Python simulations and a real-time implementation in JUCE/C++.

Binary files for each plugin can be found in the Bin/ folder. Currently only Windows builds and unsigned Mac builds are available.
