End Type

Members

fEdge

Percentage of distortion intensity. The default value is 15. Minimum and maximum values are defined in the CONST_DSFXDISTORTION_EDGE enumeration.

fGain

Amount of signal change after distortion, in decibels. The default value is -18. Minimum and maximum values are defined in the CONST_DSFXDISTORTION_GAIN enumeration.

fPostEQBandwidth

Width of frequency band that determines range of harmonic content addition, in Hertz. The default value is 2400. Minimum and maximum values are defined in the CONST_DSFXDISTORTION_POSTEQBANDWIDTH enumeration.

fPostEQCenterFrequency

Center frequency of harmonic content addition, in Hertz. The default value is 2400. Minimum and maximum values are defined in the CONST_DSFXDISTORTION_POSTEQCENTERFREQUENCY enumeration.

fPreLowpassCUTOFF

Filter cutoff for high-frequency harmonics attenuation, in Hertz. The default value is 8000. Minimum and maximum values are defined in the CONST_DSFXDISTORTION_PRELOWPASSCUTOFF enumeration.

Remarks

The values in fPostEQBandwidth, fPostEQCenterFrequency, and fPreLowpassCutoff 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.
