Digital Effects 5.5
5.5.2 Delay
A delay essentially creates an echo, although you can often use
delays to create more complex time-based effects. The source signal
is delayed so that it is heard later than it actually occurred.
Delay Time. Delay time is the time between the source signal and its
echo. The simplest delay effect is a single repeat. A short delay between
30 and 100 ms can be used to create slap-back echo, while longer delay
times produce a more distant echo. Delay times that are too short to
hear as distinct echoes can be used to create thickening effects. Whether
these echoes are timed with the tempo is a matter of stylistic choice.
Variable Feedback.
Variable feedback, or regeneration, produces multiple
decaying repeats. Increasing the feedback value increases the number of echoes
as well as the resonance that is created as one echo disappears into another.
