Description::
|
||
|
|
|
||
|
|
This is a linear filter that removes DC bias from a signal. Specifically, this is a one-pole highpass filter implementing the formula code:: 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.
