title: Tegra210 PEQ
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).
