Wolf Shaper

Wolf Shaper is a free, open-source distortion plugin that lets you create your own waveshaping functions using a spline-based graph editor.

This tool makes the input signal more harmonically rich, which can be useful for sound design and mixing.

Pre – Controls the input volume, before any processing has taken place.
Wet – Determines the mix between the original and the processed signal in the output. Set this parameter at maximum value to only hear the processed signal.
Post – Controls the output volume, after all processing has been done.
Center – Removes DC offset from the output. This ensures that the resulting waveform is vertically centered at zero.
Oversample – Sets the multiple of the sample rate at which the processing will be done. This allows the plugin to filter out some harmonics that would otherwise cause aliasing artifacts.
Uni/Bi switch – Allows switching between symmetrical and asymmetrical waveshaping.
Warp knobs - The two yellow knobs in the middle of the UI allow to bend the distortion curve dynamically. These knobs can be automated by the plugin host for interesting effects.
Reset button – Puts the graph back at its default state, which is a straight diagonal line.

Add a vertex – Right-click in the graph to add a vertex. Keep holding the right mouse button to position the vertex.
Move a vertex – Left-click and drag the vertex.
Remove a vertex – Double left-click on the vertex.
Tweak the tension of an edge – Left-click and drag vertically the tension handle located at the center of the edge.
Change the curve type - Right-click on a vertex, then select the curve type in the context menu.

Resize the window – Left-click and drag the resize handle located at the bottom-right to resize the window.
