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
