Examples of javax.sound.sampled.Clip

javax.sound.sampled.Clip
The Clip interface represents a special kind of data line whose audio data can be loaded prior to playback, instead of being streamed in real time.
Because the data is pre-loaded and has a known length, you can set a clip to start playing at any position in its audio data. You can also create a loop, so that when the clip is played it will cycle repeatedly. Loops are specified with a starting and ending sample frame, along with the number of times that the loop should be played.
Clips may be obtained from a {@link Mixer} that supports lines of this type. Data is loaded into a clip when it is opened.
Playback of an audio clip may be started and stopped using the start and stop methods. These methods do not reset the media position; start causes playback to continue from the position where playback was last stopped. To restart playback from the beginning of the clip's audio data, simply follow the invocation of {@link DataLine#stop stop} with setFramePosition(0), which rewinds the media to the beginning of the clip. @author Kara Kytle @since 1.3
