Struct ParametricEq 

pub struct ParametricEq { /* private fields */ }

3-Band Parametric Equalizer

A flexible tone-shaping EQ with:

• Low shelf (50-500 Hz)
• Parametric mid with adjustable Q (200 Hz - 8 kHz)
• High shelf (2-12 kHz)

Each band has ±12dB gain range. Uses biquad filters in Transposed Direct Form II for numerical stability.
