I am using lop~ and hip~ filters in a real time audio application, at a sample rate of 48kHz.
Something I read in the help of an external library has me worried they may not be working as I expected.
A variant of [lop~] that has a signal-controlled cutoff. Like [lop~], the filter has no effect when the cutoff is above SR/(2pi)
Is this saying the filters are only working to about 5kHz?
