RLPF resonant low pass filter


Inherits from: Object : AbstractFunction : UGen : Filter 


A resonant low pass filter.


RLPF.ar(in, freq, rq, mul, add)

RLPF.kr(in, freq, rq, mul, add)


in - input signal to be processed

freq - cutoff frequency.

rq - the reciprocal of Q.  bandwidth / cutoffFreq.

// modulate cutoff frequency
