Note: Band gain is expressed in millidecibels.
Class has by default 10 equalizer bands. See SetEqualizerPoints. If you create custom bands, use correct number of bands as nNumberOfBands parameter. And don't forget to specify pnBandGain array with correct size.
If you create 20 equalizer bands, then you need to send pointer to 20 values as pnBandGain parameter.
