sounds.APSoundClip
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.
