Overdraw

Overdraw is a free and open source VST/VST3 audio plug-in that implements a waveshaper in which the user can draw the transfer function of each channel using splines.

Features:

• The transfer functions are smoothly automatable splines.
• Optional Mid/Side Stereo processing.
• All the parameters, including the knots of the spline, 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 Stereo Mode.
• Dry-Wet percentage.
• 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, the smoothing time, or the input and output gains.

Spline Editing:

• The splines can be edited either by dragging the knots with the mouse, or by entering numeric values for the selected knot.
• To enable or disable a knot, double click on it.
• When the knots of two different channel are overlapping, the mouse will interact with the control point of the Left/Mid channel.
• To interact with the knot of the Right/Side channel, use the right button of your mouse, or press the ALT key while clicking.
• To zoom in or out, use the mouse scroll wheel.
