Chapter 5: DigiRack D-Fx Plug-Ins
D-Fx is a set of four AudioSuite plug-ins:
• Chorus
• Flanger
• Multi-Tap Delay
• Pin-Pong Delay
Chorus
(AudioSuite Only)
Chorus adds a shimmering quality to audio material by combining a time-delayed, pitchshifted copy of an audio signal with itself.
Gain Adjusts the input volume of the chorus to prevent clipping or increase the level of the processed signal. This slider is set to a default of
+3 dB. If your source audio has been recorded very close to peak level, this +3 dB default setting could cause clipping. Use this control to reduce the input level.
Selecting the Sum Inputs button sums the dry input signals (mono or stereo) before processing them. The dry signal then appears in the center of the stereo field and the wet, effected signal will be output in stereo.
When the Sum Inputs button is selected, the
LFO waveform on the right channel is automatically phase inverted to enhance the mono-stereo effect.
Chorus plug-in
The Chorus plug-in was formerly called
D-fx Chorus. It is fully compatible with all settings and presets created for D-fx Chorus.
Sum Inputs button
Mix Adjusts the balance between the effected signal and the original signal and controls the depth of the effect. Mix is adjustable from 0% to
100%.
Low-Pass Filter Controls the cutoff frequency of the Low-Pass Filter. Use this to attenuate the high frequency content of the feedback signal.
The lower the setting, the more high frequencies are removed from the feedback signal.
Chapter 5: DigiRack D-Fx Plug-Ins 19
The range of the Low-Pass Filter is 20 Hz to
19.86 kHz, with a maximum value of Off (which effectively means bypass).
Delay Sets the delay time between the original signal and the chorused signal. The higher the setting, the longer the delay and the wider the chorusing effect. Delay is adjustable from 0–20 milliseconds.
LFO Rate Adjusts the rate of the LFO (low frequency oscillator) applied to the delayed signal as modulation. The higher the setting, the more rapid the modulation. You can select either a sine wave or a triangle wave as a modulation source, using the LFO Waveform selector.
LFO Width Adjusts the intensity of the LFO applied to the delayed signal as modulation. The higher the setting, the more intense the modulation. Use the LFO Waveform selector to select a sine or a triangle wave as a modulation source.
Feedback Controls the amount of feedback applied from the output of the delayed signal back into its input. Negative settings provide a more intense effect.
LFO Waveform Selects a sine wave or triangle wave for the LFO. This affects the character of the modulation. The sine wave has a gentler ramp and peak than the triangle wave.
Flanger
(AudioSuite Only)
The Flanger animates and adds a swirling, moving quality to audio material by combing a timedelayed copy of an audio signal with itself.
The Flanger uses a through-zero flanging algorithm that results in a tape-like flanging effect.
This technique delays the original dry signal by
256 samples, then modulates the delayed signal back and forth in time in relation to the dry signal, passing through its zero point on the way.
Flanger plug-in
The Flanger plug-in was formerly called
D-fx Flanger. It is fully compatible with all settings and presets created for D-fx
Flanger.
Gain Adjusts the input volume of the flanger to prevent clipping or increase the level of the processed signal. This slider is set to a default of
+3 dB. If your source audio has been recorded very close to peak level, this +3 dB default setting could cause clipping. Use this control to reduce the input level.
Selecting the Sum Inputs button sums the dry input signals (mono and stereo) before processing them. The dry signal then appears in the center of the stereo field and the wet, effected signal will be output in stereo.
20 Audio Plug-Ins Guide
When the Sum Inputs button is selected, the
LFO waveform on the right channel is phase inverted to enhance the mono-stereo effect.
Mix Adjusts the balance between the effected signal and the original signal and controls the depth of the effect. Mix is adjustable from 0% to
100%.
High-Pass Filter Controls the cutoff frequency of the high-pass filter. Use this to attenuate the frequency content of the feedback signal and the frequency response of the flanging. The higher the setting, the more low frequencies are removed from the feedback signal.
LFO Rate Adjusts the rate of the LFO (low frequency oscillator) applied to the delayed signal as modulation. The higher the setting, the more rapid the modulation. You can select either a sine wave or a triangle wave as a modulation source, using the LFO Waveform selector.
LFO Width Adjusts the intensity of the LFO applied to the delayed signal as modulation. The higher the setting, the more intense the modulation.
Feedback Controls the amount of feedback applied from the output of the delayed signal back into its input. Negative settings provide a more intense effect.
LFO Waveform Selects a sine wave or triangle wave for the LFO. This affects the character of the modulation. The sine wave has a gentler ramp and peak than the triangle wave.
Multi-Tap Delay
(AudioSuite Only)
The Multi-Tap Delay adds up to four independently-controllable delays or taps to the original audio signal. Use the Multi-tap delay to add spatialization or complex rhythmic echo effects to audio material. You can individually control the delay time and number of repetitions of each of the four taps.
Multi-Tap Delay plug-in
The Multi-Tap Delay plug-in was formerly called D-fx Multi-Tap Delay. It is fully compatible with all settings and presets created for D-fx Multi-Tap Delay.
Chapter 5: DigiRack D-Fx Plug-Ins 21
Gain Provides individual control of the input level for each of the four delay lines (or “taps”).
Individually adjust the Gain for each of the four taps, either to prevent clipping or to increase the level of the processed signal.
Selecting the Sum Inputs button sums the dry input signals (mono or stereo) before processing them. The dry signal then appears in the center of the stereo field and the wet, effected signal will be output in stereo.
Feedback Provides individual control over the amount of feedback applied from the output of the delay into its input for each tap. It also controls the number of repetitions of the delayed signal. For the feedback feature to function, the
Gain slider for that tap must be raised above its lowest setting.
Pan Provides individual control over the apparent location of each of the four taps in the stereo field.
Delay Sets the delay time between the original signal and the delayed signal. The higher the setting, the longer the delay. This control is adjustable from 0–1500 milliseconds (1.5 seconds).
Mix Adjusts the balance between the effected signal and the original signal and controls the depth of the effect. Mix is adjustable from 0% to
100%.
Ping-Pong Delay
(AudioSuite Only)
The Ping-Pong Delay plug-in adds a controllable delay to the original audio signal. Use the Ping-
Pong delay to add spatialization, and panned echo to audio material. This plug-in feeds back delayed signals to their opposite channels, creating a characteristic ping-pong echo effect.
Ping-Pong Delay plug-in
The Ping-Pong Delay plug-in was formerly called D-fx Ping-Pong Delay. It is fully compatible with all settings and presets created for D-fx Ping-Pong Delay.
Gain Adjusts the input volume of the Ping-Pong
Delay to prevent clipping or to increase the level of the processed signal.
Mix Adjusts the balance between the effected signal and the original signal and controls the depth of the effect. Mix is adjustable from 0% to
100%.
Delay Sets the delay time between the original signal and the delayed signal. The higher the setting, the longer the delay. This control is adjustable from 0–1500 milliseconds (1.5 seconds).
Low-Pass Filter Controls the cutoff frequency of the low-pass filter. Use this to attenuate the high frequency content of the feedback signal. The lower the setting, the more high frequencies are removed from the feedback signal.
22 Audio Plug-Ins Guide
The range of the Low-Pass Filter is 20 Hz to
19.86 kHz, with a maximum value of Off (which effectively means bypass).
Feedback Controls the amount of feedback applied from the output of the delay into its input.
It also controls the number of repetitions of the delayed signal.
Cross-Feedback Cross-Feedback feeds the delayed signals to their opposite channel: The left channel delay is fed to the right channel input and vice-versa. The result is a stereo echo that ping-pongs back and forth between the right and left channels.
Selecting Audio for
AudioSuite Delay Processing
Because delays add additional material to the end of selected audio (a delay tap), make a selection that is longer than the original source material so AudioSuite can write the additional delayed audio to the audio file.
Selecting only the original material, without leaving additional space at the end results in the delayed audio being cutoff at the end of the selection. To accommodate delayed audio that comes after the source audio, place the region in a track, and select the desired audio plus an amount of blank space at the end of the region equal to the amount of delay that you have added in the plug-in. The plug-in will then have space at the end of the region in which to write the final delay.
