| //================================================================================ | |
| // | |
| // This collection implements high-quality, double-precision second-order filters | |
| // based on the work of Vicanek, offering improved frequency accuracy and dynamic | |
| // response over traditional biquads—especially near Nyquist. | |
| // | |
| // Standard digital filter designs (like bilinear-transformed biquads) suffer from | |
| // frequency warping, which distorts the placement of poles and zeros. Vicanek's |

| // Based on the Audio EQ Cookbook by Robert Bristow-Johnson | |

| // | |
| // This implementation uses the standard RBJ formulas which inherently | |
