LeakDC : Filter : PureUGen : UGen : AbstractFunction : Object

Description

This is a linear filter that removes DC bias from a signal. Specifically, this is a one-pole highpass filter implementing the formula y[n] = x[n] - x[n-1] + coef * y[n-1]. The frequency response of this filter is dependent on the sample rate of the server and the calculation rate of the UGen.
