Digital equalization has been haunted by a fundamental mathematical compromise since the dawn of the digital audio workstation: Frequency Cramping . When you map an analog filter to the digital domain using the standard Bilinear Transform (BLT), the frequency response warps catastrophically as it approaches the Nyquist frequency (half your sample rate).…
