October 2012 BPF was changed to use double-precision floats (git commit: 72412f63affa94f69e2ea7539e21831a1d0d3e01). GlitchBPF can be used as drop-in replacements to get the old behavior back. Good for very noise and glitchy sounds where the filter [nearly] blows up.
in |
The input signal. |
freq |
Centre frequency in Hertz. |
rq |
The reciprocal of Q. Q is conventionally defined as cutoffFreq / bandwidth, meaning rq = (bandwidth / cutoffFreq). |
mul |
Output will be multiplied by this value. |
add |
This value will be added to the output. |
