Hello, I am trying to figure out how to calculate the latency for HIIR.

from what I understand you need to call the `compute_group_delay(const double coef_arr[], int nbr_coefs, double f_fs, bool ph_flag)`

function, but I’m stuck on the `f_fs`

argument.

The comments say “frequency relative to the sampling rate” but never mentions how to get the frequency, and is the sampling rate the oversampled sampling rate or the non oversampled?

Thanks
