cutoff. The Pad parameter, as always, attenuates the signal at the input to the function. These
parameters affect all the highpass filters similarly.
Two-pole Highpass Filter (HIPAS2)
This is very similar to HIPASS. The primary difference is in the steepness of the rolloff at the
cutoff frequency. Below the cutoff frequency, the rolloff is similar to that of HIPASS, except that
there’s a one-octave shift—that is, HIPASS with a cutoff frequency of C 3 will sound nearly the
same as HIPAS2 with a cutoff of C 4. In other words, HIPASS gives you greater attenuation of
low frequencies when set to the same cutoff frequency as HIPAS2.
