object RLPF extends ProductReader[RLPF] with Serializable
A resonant low pass filter UGen.
Examples
// mouse controlled frequency and Q play { val in = WhiteNoise.ar(0.5) val freq = MouseX.kr(200, 10000, 1) val q = MouseY.kr(1, 100, 1) // bottom to top val flt = RLPF.ar(in, freq, q.reciprocal) flt / q.sqrt // compensate for energy loss }

input signal to be filtered
- freq
cutoff frequency in Hertz
- rq
reciprocal of Q. The Q (or quality) is conventionally defined as cutoff-frequency / bandwidth, meaning that rq = bandwidth / cutoff-frequency. A higher Q or lower rq produces a steeper filter.
