| Modifier and Type | Method and Description |
|---|---|
void |
build()
The build method can be overriden by Audio Objects
to provide any extra initialization that may be
required before the Audio Object can be used for
each new note that needs rendering.
|
void |
coefficientCalc()
Calculate the filter coefficients from a cascade of pole pairs.
|
void |
printCoefficients()
Print this filter's coefficients
|
void |
setCutOff(double freq)
Sets the cutoff frequency and adjusts the coefficients suitably
|
void |
setPoles(int newPole)
Specify the filter pole variable.
|
int |
work(float[] buffer)
Processes the sample values.
