15
16argument::in
17
18The input signal.
19
20
21argument::freq
22
23Cutoff frequency in Hertz.
24WARNING: due to the nature of its implementation frequency values close to 0 may cause glitches and/or extremely loud audio artifacts!
25
26argument::rq
27
28The reciprocal of Q (bandwidth / cutoffFreq).
