Class Methods

BPF.ar(in: 0.0, freq: 440.0, rq: 1.0, mul: 1.0, add: 0.0)

Arguments:

in

The input signal.

freq

Centre frequency in Hertz. WARNING: due to the nature of its implementation frequency values close to 0 may cause glitches and/or extremely loud audio artifacts!

rq

The reciprocal of Q. Q is conventionally defined as freq / bandwidth, meaning rq = (bandwidth / freq).
