Members
- fGain
- Amount of signal change after distortion, in the range from DSFXDISTORTION_GAIN_MIN through DSFXDISTORTION_GAIN_MAX. The default value is 0 dB.
- fEdge
- Percentage of distortion intensity, in the range in the range from DSFXDISTORTION_EDGE_MIN through DSFXDISTORTION_EDGE_MAX. The default value is 50 percent.
- fPostEQCenterFrequency
- Center frequency of harmonic content addition, in the range from DSFXDISTORTION_POSTEQCENTERFREQUENCY_MIN through DSFXDISTORTION_POSTEQCENTERFREQUENCY_MAX. The default value is 4000 Hz.
- fPostEQBandwidth
- Width of frequency band that determines range of harmonic content addition, in the range from DSFXDISTORTION_POSTEQBANDWIDTH_MIN through DSFXDISTORTION_POSTEQBANDWIDTH_MAX. The default value is 4000 Hz.
- fPreLowpassCutoff
- Filter cutoff for high-frequency harmonics attenuation, in the range from DSFXDISTORTION_PRELOWPASSCUTOFF_MIN through DSFXDISTORTION_PRELOWPASSCUTOFF_MAX. The default value is 4000 Hz.
Remarks
The values in fPostEQBandwidth, fPostEQCenterFrequency, and fPreLowpassCutoff cannot exceed one-third of the frequency of the buffer.
