Float32Array:
input freq values, with poles and zeros applied
Evaluates the poles and zeros at the given value. The return value is 1/(pz(s) to avoid divide by zero issues. If there is a divide by zero situation, then the response is set to be 0+0i.

Converts a StationXML response to SAC PoleZero style. This converts the analog to digital stage (usually 0) along with the overall gain, but does not include later FIR stages. To maintain compatibility with SAC, this includes extra zeros if needed to convert to displacement. The number of extra zeros added is kept as gamma in the result.
