Examples of com.sun.speech.freetts.audio.JavaStreamingAudioPlayer

• com.sun.speech.freetts.audio.JavaStreamingAudioPlayer
  Streams audio to java audio. This class provides a low latency method of sending audio output through the javax.sound audio API. Audio data is sent in small sets to the audio system allowing it to be played soon after it is generated. Unfortunately, the current release of the JDK (JDK 1.4 beta 2) has a bug or two in the implementation of 'SourceDataLine.drain'. A workaround solution that sleep/waits on SourceDataLine.isActive is used here instead. To disable the work around (i.e use the real 'drain') set the property:

  com.sun.speech.freetts.audio.AudioPlayer.drainWorksProperly; to true. If the workaround is enabled, the line.isActive method will be performed periodically. The period of the test can be controlled with:

  com.sun.speech.freetts.audio.AudioPlayer.drainDelay"

  The default if 5ms.

  The property com.sun.speech.freetts.audio.AudioPlayer.bufferSize"

  Controls the audio buffer size, it defaults to 8192

  Even with this drain work around, there are some issues with this class. The workaround drain is not completely reliable. A resume following a pause does not always continue at the proper position in the audio. On a rare occasion, sound output will be repeated a number of times. This may be related to bug 4421330 in the Bug Parade database.
