  • enabled

    public BooleanProperty enabledProperty

    Whether the AudioEqualizer is enabled. The default value is true.

• Field Detail

  • MAX_NUM_BANDS

    public static final int MAX_NUM_BANDS

    Maximum number of bands an AudioEqualizer may contain. In the current implementation this value is 64.

• Method Detail

  • getBands

    public final ObservableList<EqualizerBand> getBands()

    ObservableList containing EqualizerBand elements. The content of the sequence may be changed by adding or removing EqualizerBand elements. When adding elements, the user must be prepared to catch IllegalArgumentExceptions because the internal list is a VetoableObservableList and any change to the list can be vetoed if a newly added instance is not valid.

    The constraints for a valid EqualizerBand instance are:

    • EqualizerBand.centerFrequency > 0
    • EqualizerBand.bandwidth > 0
    • EqualizerBand.MIN_GAIN ≤ EqualizerBand.gain ≤ EqualizerBand.MAX_GAIN

    The default set of bands is as in the following table; all bands have unity gain (0 dB).

    Band Index	Center Frequency (Hz)	Bandwidth (Hz)
    0	32	19
    1	64	39
    2	125	78
    3	250	156
    4	500	312
    5	1000	625
    6	2000	1250
    7	4000	2500
    8	8000	5000
    9	16000	10000

    Returns:

    ObservableList containing EqualizerBand elements.

    Throws:

    IllegalArgumentException

  • setEnabled

    public final void setEnabled(boolean value)

    Enables or disables AudioEqualizer. If the enabled property is set to false, AudioEqualizer settings are preserved but not taken into account during playback, which is equivalent to setting all EqualizerBand.gain properties to zero.

  • isEnabled

    public final boolean isEnabled()

    Return enabled state of the AudioEqualizer.

    Returns:

    true if AudioEqulizer is enabled, false otherwise.

  • enabledProperty

    public BooleanProperty enabledProperty()

    Whether the AudioEqualizer is enabled. The default value is true.
