Class OggAudioStatistics

java.lang.Object

org.gagravarr.ogg.audio.OggAudioStatistics

Direct Known Subclasses:

OpusStatistics

public class OggAudioStatistics
extends Object

For computing statistics around an OggAudioStream, such as how long it lasts. Format specific subclasses may be able to also identify additional statistics beyond these.
