public class APSoundClip
LICENSE: This is open-source software released under the terms of the
GPL (http://www.gnu.org/licenses/gpl.html).
This class supports the processing of sound clips.
Input files must be in WAVE format. Output files are written in WAVE format.
Example program, which loads a sound clip from a file,
increases its volume, plays it and draws its wave form:
import sounds.APSoundClip;
import sounds.Sample;
public class TestVolume{
public static void main(String[]args){
APSoundClip clip = new APSoundClip();
for (Sample s : clip){
int value = s.getValue();
s.setValue(value * 2);
}
clip.play();
clip.draw();
}
}java -Xmxnew Sizem programFileNamewhere newSize is an integer. For example,
java -Xmx128m TestVolumeallows up to 128 megabytes of heap space for the TestVolume program.
