.. _auto_complexcurve_to_pressure_db:

*CONVERT COMPLEX CURVE TO PRESSURE DB*
======================================

Converts a complex curve (real + imaginary components) to a pressure level in decibels (dB). Use this worker in NVH or acoustics workflows where raw complex frequency-domain data must be expressed as a sound-pressure or pressure-amplitude level.

     - Complex-valued input curve (real + imaginary parts, typically a frequency-domain vector) whose magnitude will be converted to a pressure dB value; leave unconnected if the conversion is to be skipped.
