BiQuadCoeffs Struct Reference

Biquad coefficients, always computed in float regardless of the filter's sample type T. Intermediate values like the angular cutoff frequency w0 range up to PI (~3.14) at Nyquist, which overflows bounded fixed-point sample types like q1_14_t (range ~[-2,2)); only the final, range-safe coefficients (typically within [-2,2) for a stable filter) get cast into T when assigned to a BiQuadDF1/BiQuadDF2 instance.
