The ArcTangent block computes the inverse tangent (atan) of a single control input and writes the resulting angle, in radians, to a control output. It is a control-domain math operator with no adjustable parameters. atan accepts any real input; its output ranges from -pi/2 to pi/2.
On every tick it reads the incoming control value, applies the standard-library atan function and stores the angle on the output control pin. It holds no state and processes one sample-frame per tick, in step with WaveWarp's sample-per-sample engine.
