ShapeMod: Envelope Shaper Plugin by Plugin Boutique

The main envelope section lets you draw a volume shape with as many nodes as you need, which allows detailed rhythmic patterns. Start and end points are unlinked, so the envelope does not have to loop cleanly on its own edges. A flip control reverses the direction of playback.

Time syncing covers 1/32 to 32 bars, with straight, dotted and triplet subdivisions. The amount control sets the depth of the effect, and a phase adjustment moves the starting point of the envelope within its cycle.

A spectrum analyser or moving waveform display shows the signal as it is processed, which helps when lining up the shape with the audio.

Frequency focus controls let you apply the volume shaping to a specific band, so a ducking effect can affect only the low end or only the highs. The mid/side balance control narrows the effect to the mid or side signal.

The developer lists sidechain-style ducking on bass, pumping effects in time with a kick drum, tremolo on synths and pads, rhythmic gating, and tension and release during key moments in a track. A smoothing control reduces pops and clicks, and a pulse width modulation control adds what Plugin Boutique describes as an analogue feel.

The plugin ships with 75 presets as starting points.
