The ArcSinh block computes the inverse hyperbolic sine (asinh) of a single control input and writes the result to a control output. It is a control-domain math operator with no adjustable parameters — the transfer is fixed. asinh is defined for every real input value.
On every tick it reads the incoming control value, applies the standard-library asinh function and stores the result 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.
