Review of Delay Parameters and Their Functions



The Modulated Delay

The Modulated Delay (a.k.a. Mod Delay) provides time delay-based effects. Effects obtained through the use of Mod Delay include slap echo, doubling, chorusing, and flanging.


There are four different Mod Delays, each of which is capable of a different maximum delay time:

1) The Short Delay

1024 samples of delay (23.2 milliseconds @ 44.1 kHz or 21.3 ms @ 48 kHz).


2) The Slap Delay

7186 samples of delay (162 ms @ 44.1 kHz or 149 ms @ 48 kHz).


3) The Medium Delay

16384 samples of delay (371 ms @ 44.1 kHz or 341 ms @ 48 kHz).


4) The Long Delay

162474 samples of delay (3.68 seconds @ 44.1 kHz or 3.38 seconds @ 48 kHz).



Mod Delay Parameters



Controls the input volume of the delay, preventing clipping.



Controls the balance between the delayed signal and the original signal. If the effect is at the insert of a track, you must create your 'mix' or 'blend' of effect (the wet signal) and original audio track (the dry signal) at the plug-in. However, when you use the Sends and Returns with plug-ins, it is typical to have the effect at the return channel on full wet. This is because you create the balance by sending more or less audio from a track to the plug-in. This creates a balance or blend between the Send and the Return levels.


LPF (Low Pass Filter)

Controls the cutoff frequency of the low-pass filter. This allows you to attenuate the high frequency content of the feedback signal. The lower the setting, the more high frequencies are attenuated.



Sets the delay time between the original signal and the delayed signal.



Controls the depth of the modulation applied to the delayed signal.



Controls the rate of modulation of the delayed signal.



Controls the amount of output signal that is sent back into its input. It also controls the number of repretitions of the delayed signal. Negative feedback settings give a more intense tunnel-like sound to flanging effects.
