Overdraw

Overdraw is an audio plug-in that implements a waveshaper in which the transfer function of each channel is an automatable spline.

Features

• The transfer functions are smoothly automatable splines.
• Optional Mid/Side Stereo processing.
• All parameters, and all splines, can have different values on the Left channel and on the Right channel - or on the Mid channel and on the Side channel, when in Mid/Side Stero Mode.
• Dry-Wet.
• Up to 32x Oversampling with either Minimum Phase or Linear Phase Antialiasing.
• VU meter showing the difference between the input level and the output level.
• Customizable smoothing time, used to avoid zips when automating the knots of the splines, the wet amount, or the input and output gains.

Build

Clone with

git clone --recursive https://github.com/unevens/Overdraw

Overdraw uses the JUCE cross-platform C++ framework.

You'll need Projucer to open the file Overdraw.jucer and generate the platform specific builds.

Supported platforms

Overdraw is developed and tested on Windows and Ubuntu. It may also work on macOS, but I can neither confirm nor deny.

VST and VST3 binaries are available at https://www.unevens.net/overdraw.html.

Submodules, libraries, credits

• The oversimple submodule is a wrapper around two resampling libraries:
  • HIIR library by Laurent de Soras, "a 2x Upsampler/Downsampler with two-path polyphase IIR anti-aliasing filtering".
  • r8brain-free-src, "an high-quality pro audio sample rate converter / resampler C++ library" by Aleksey Vaneev.
• audio-dsp, my toolbox for audio dsp and SIMD instructions, which uses Agner Fog's vectorclass and Boost.Align.
