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

Overdraw uses the JUCE cross-platform C++ framework.
You'll need Projucer to open the file Overdraw.jucer and generate the platform specific builds.
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.
- 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.
Overdraw is released under the GNU GPLv3 license.
