dB.public EqualizerBand()
EqualizerBand
default constructor. It creates an instance with
centerFrequency
, bandwidth
and gain
set to 0.public EqualizerBand(double centerFrequency, double bandwidth, double gain)
EqualizerBand
constructor. It creates an instance
from the centerFrequency
, bandwidth
and
gain
parameters. The gain
specifies the amount
of amplification (gain > 0.0
dB) or attenuation
(gain < 0.0
dB) to be applied to the center frequency of
the band. The bandwidth is the frequency spread between the upper and
lower edges of the equalizer transfer function which have half the dB gain
of the peak (center frequency).public final void setCenterFrequency(double value)
