.. _auto_curve_to_db:

*CONVERT CURVE TO DB*
=====================

Converts a pressure or amplitude curve to decibels (dB) using a provided scaling factor. Use this worker whenever raw pressure or signal curves need to be expressed on a logarithmic dB scale for NVH or acoustics post-processing.

When to use

     - The input amplitude or pressure curve (vector of x/y pairs) to be converted to dB; supply a valid Curve object — leave empty only if the conversion is to be skipped.
