Method Detail

applyFilter

public abstract void applyFilter(double[] source,
                                 double[] destination)

Apply the filter (sample-by-sample). This method must be implemented by concrete children.

Parameters:

source - The signal from source

destination - The destination signals

applyFilter

public void applyFilter(java.util.Iterator<double[]> source,
                        java.util.Iterator<double[]> destination)

Apply the filter to all of the channels.

Parameters:

source - The source signals

destination - The destination signals

filter

public BufferedSound filter(BufferedSound src,
                            BufferedSound dest)

A two-source/one-destination filter. If the destination is null, a BufferedSound with an appropriate AudioFormat and length is created and returned.

Specified by:

filter in interface BufferedSoundUnaryOp

Parameters:

src - The operand (i.e., the sound to operate on)

dest - An empty sound to hold the result (or null)
