Waveshaper can be used for distortion and shaping the waveform of the signal. This plugin is very similar to Dynamics Processor.
Curve: represents dynamic range in a linear scale of 0-1 amplitude.
X axis: represents the peak level of input.
Y axis: represents target level of output.
Left Click draws lines following the cursor.
Shift + Left Click draws a straight line between the current and last point.
+/- 1dB: shifts graph line along the Y axis.
SMOOTH: smooths graph via cubic interpolation.
RESET: nukes graph and reverts it to default
INPUT: adjusts level of input gain.
OUTPUT: adjusts level of output gain.
Clip input: toggles clipping of the input signal to 0dBV (or 1) before processing.
