|
|
|
|
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).
