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).

Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
