Members
- fWetDryMix
- Ratio of wet (processed) signal to dry (unprocessed) signal. Must be in the range from DSFXFLANGER_WETDRYMIX_MIN through DSFXFLANGER_WETDRYMIX_MAX (all wet).
- fDepth
- Percentage by which the delay time is modulated by the low-frequency oscillator (LFO), in hundredths of a percentage point. Must be in the range from DSFXFLANGER_DEPTH_MIN through DSFXFLANGER_DEPTH_MAX. The default value is 25.
- fFeedback
- Percentage of output signal to feed back into the effect's input, in the range from DSFXFLANGER_FEEDBACK_MIN to DSFXFLANGER_FEEDBACK_MAX. The default value is 0.
- fFrequency
- Frequency of the LFO, in the range from DSFXFLANGER_FREQUENCY_MIN to DSFXFLANGER_FREQUENCY_MAX. The default value is 0.
- lWaveform
- Waveform of the LFO. By default, the waveform is a sine. Possible values are defined as follows:
- DSFXFLANGER_WAVE_TRIANGLE
- Triangle.
- DSFXFLANGER_WAVE_SIN
- Sine.
- fDelay
- Number of milliseconds the input is delayed before it is played back, in the range from DSFXFLANGER_DELAY_MIN to DSFXFLANGER_DELAY_MAX. The default value is 0 ms.
- lPhase
- Phase differential between left and right LFOs, in the range from DSFXFLANGER_PHASE_MIN through DSFXFLANGER_PHASE_MAX. Possible values are defined as follows:
- DSFXFLANGER_PHASE_NEG_180
DSFXFLANGER_PHASE_NEG_90
DSFXFLANGER_PHASE_ZERO
DSFXFLANGER_PHASE_90
DSFXFLANGER_PHASE_180
