| 9 | description: |
| 10 | The Parametric Equalizer (PEQ) is a cascade of biquad filters with |
| 11 | each filter tuned based on certain parameters. It can be used to |
| 12 | equalize the irregularities in the speaker frequency response. |
| 13 | PEQ sits inside Output Processing Engine (OPE) which interfaces |
| 14 | with Audio Hub (AHUB) via Audio Client Interface (ACIF). |
