.. _auto_curve_aweight:

*CONVERT REAL CURVE TO AWEIGHT*
===============================

Applies A-weighting to a frequency-domain curve, converting raw (linear) amplitude values to perceptually weighted dB(A) levels. Use this worker when preparing acoustic or NVH signal data for human-hearing-based assessments.
