fBandwidth

Bandwidth, in semitones. Minimum and maximum values are defined in the CONST_DSFXPARAMEQ_BANDWIDTH enumeration. The default value is 12.

fCenter

Center frequency, in hertz. Minimum and maximum values are defined in the CONST_DSFXPARAMEQ_CENTER enumeration. This value cannot exceed one-third of the frequency of the buffer. The default value is 8000.

fGain

Gain, in decibels. Minimum and maximum values are defined in the CONST_DSFXPARAMEQ_GAIN enumeration. The default value is 0.

Remarks

The value in fCenter cannot exceed one-third of the frequency of the buffer. If an attempt is made to set a higher value, the parameter is set to the nearest supported value.
