Class GainProcessor

java.lang.Object

be.tarsos.dsp.GainProcessor

All Implemented Interfaces:

AudioProcessor

public class GainProcessor
extends java.lang.Object
implements AudioProcessor

With the gain processor it is possible to adapt the volume of the sound. With a gain of 1, nothing happens. A gain greater than one is a volume increase a gain between zero and one, exclusive, is a decrease. If you need to flip the sign of the audio samples, you can by providing a gain of -1.0. but I have no idea what you could gain by doing that (pathetic pun, I know).
