object LeakDC extends ProductReader[LeakDC] with Serializable
A filter UGen to remove very low frequency content DC offset.
This is a one-pole highpass filter implementing the formula
y[n] = x[n] - x[n-1] + coeff * y[n-1]
Examples
// show DC with mouse-controlled coefficient play { val freq = 800 val in = LFPulse.ar(freq).mulAdd(0.5, 0.5) val coef = MouseX.kr(0.9, 0.999) val flt = LeakDC.ar(in, coef) val dc = RunningSum.ar(flt, SampleRate.ir/freq) coef.poll(2) dc .poll(2) 0 }

the leak coefficient determines the filter strength. the value must be between zero and one (exclusive) for the filter to remain stable. values closer to one produce less bass attenuation.
