KDFX Algorithm Specifications
Wet/Dry The amount of phaser (wet) signal relative to unaffected (dry) signal as a percent. When
set to 50% you get a complete notch. When set to -50%, the response is a bandpass
fi lter.
100% is a pure allpass fi lter (no amplitude changes, but a strong phase response).
Out Gain The output gain in decibels (dB) to be applied to the combined wet and dry signals.
CenterFreq The nominal center frequency of the phaser fi lter. The frequency LFO modulates the
phaser fi lter centered at this frequency.
Bandwidth If the phaser is set to behave as a sweeping notch or bandpass, the bandwidth of the notch
or bandpass is set with Bandwidth. This parameter works the same as for parametric EQ
fi lter bandwidths.
LFO Depth The depth that the frequency LFO sweeps the phaser fi lter above and below the center
frequency as a percent.
LFO Rate The rate of the LFO in Hertz. The LFO Rate may be scaled up by the Rate Scale parameter.
Rate Scale A rate multiplier value which may be used to increase the LFO frequency to audio rates.
For example, if LFO Rate is set to 1.00 Hz and Rate Scale is set to 1047x, then the LFO
frequency is 1047 x 1.00 Hz = 1047 Hz.
L/R Phase Sets the phase difference between the left and right channels of the center frequency LFO.
A setting of 180 degrees results in one being at a at the minimum frequency while the
other channel is at the maximum.
In Width The width of the stereo fi eld that passes through the stereo phaser fi ltering. This
parameter does not affect the dry signal. When set to 100%, the left and right channels are
processed to their respective outputs. Smaller values narrow the stereo image until at 0%
the input channels are summed to mono and set to left and right outputs. Negative values
interchange the left and right channels.
