| 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). |
