Class AudioClip

java.lang.Object
javafx.scene.media.AudioClip
public final class AudioClip extends Object
An AudioClip represents a segment of audio that can be played with minimal latency. Clips are loaded similarly to Media objects but have different behavior, for example, a Media cannot play itself. AudioClips are also usable immediately. Playback behavior is fire and forget: once one of the play methods is called the only operable control is stop(). An AudioClip may also be played multiple times simultaneously. To accomplish the same task using Media one would have to create a new MediaPlayer object for each sound played in parallel. Media objects are however better suited for long-playing sounds. This is primarily because AudioClip stores in memory the raw, uncompressed audio data for the entire sound, which can be quite large for long audio clips. A MediaPlayer will only have enough decompressed audio data pre-rolled in memory to play for a short amount of time so it is much more memory efficient for long clips, especially if they are compressed.

Example usage:


     AudioClip plonkSound = new AudioClip("http://somehost/path/plonk.aiff");
     plonkSound.play();

  • Property Details

    • volume

      public DoubleProperty volumeProperty
      The relative volume level at which the clip is played. Valid range is 0.0 (muted) to 1.0 (full volume). Values are clamped to this range internally so values outside this range will have no additional effect. Volume is controlled by attenuation, so values below 1.0 will reduce the sound level accordingly.
      See Also:

    • balance

      public DoubleProperty balanceProperty
      The relative left and right volume levels of the clip. Valid range is -1.0 to 1.0 where -1.0 gives full volume to the left channel while muting the right channel, 0.0 gives full volume to both channels and 1.0 gives full volume to right channel and mutes the left channel. Values outside this range are clamped internally.
      See Also:

    • rate

      public DoubleProperty rateProperty
      The relative rate at which the clip is played. Valid range is 0.125 (1/8 speed) to 8.0 (8x speed); values outside this range are clamped internally. Normal playback for a clip is 1.0; any other rate will affect pitch and duration accordingly.
      See Also:

    • pan

      public DoubleProperty panProperty
      The relative "center" of the clip. A pan value of 0.0 plays the clip normally where a -1.0 pan shifts the clip entirely to the left channel and 1.0 shifts entirely to the right channel. Unlike balance this setting mixes both channels so neither channel loses data. Setting pan on a mono clip has the same effect as setting balance, but with a much higher cost in CPU overhead so this is not recommended for mono clips.
      See Also:

    • priority

      public IntegerProperty priorityProperty
      The relative priority of the clip with respect to other clips. This value is used to determine which clips to remove when the maximum allowed number of clips is exceeded. The lower the priority, the more likely the clip is to be stopped and removed from the mixer channel it is occupying. Valid range is any integer; there are no constraints. The default priority is zero for all clips until changed. The number of simultaneous sounds that can be played is implementation- and possibly system-dependent.
      See Also:

    • cycleCount

      public IntegerProperty cycleCountProperty
      The number of times the clip will be played when play() is called. A cycleCount of 1 plays exactly once, a cycleCount of 2 plays twice and so on. Valid range is 1 or more, but setting this to INDEFINITE will cause the clip to continue looping until stop() is called.
