+
+description:
+  The Parametric Equalizer (PEQ) is a cascade of biquad filters with
+  each filter tuned based on certain parameters. It can be used to
+  equalize the irregularities in the speaker frequency response.
+  PEQ sits inside Output Processing Engine (OPE) which interfaces
+  with Audio Hub (AHUB) via Audio Client Interface (ACIF).
