Package jmri.jmrit.audio

Class JavaSoundAudioFactory

java.lang.Object
jmri.jmrit.audio.AbstractAudioFactory
jmri.jmrit.audio.JavaSoundAudioFactory
All Implemented Interfaces:
AudioFactory
public class JavaSoundAudioFactory extends AbstractAudioFactory
This is the JavaSound audio system specific AudioFactory.

The JavaSound sound system supports, where available, 2-channel stereo.

The implemented Audio objects provide an approximation of a 3D positionable audio model through the use of calculated panning and gain based on the 3D position of the individual sound sources.

This factory initialises JavaSound, provides new JavaSound-specific Audio objects and deals with clean-up operations.
