Creating Attack & Decay Characteristics for the Looped Portion
One potential problem is that the loop repeats at the same level. This is
usually acceptable for sustaining instruments (flute, organ, brass, etc.),
but is unacceptable for plucked or struck sounds, which decay over
time. Fortunately, the Dynamic Processing module provides a means to
shape the attack, sustain, and decay characteristics of a sample. You can
create a decay during the looped portion, and simulate pluck or struck
sounds.
Looped Sound
Looped Sound shaped by
Dynamic Processing
Module
Artificial Decay can be applied to a looped sound.
Loop Compression
The looped section of the sample can be compressed, which "evens out"
any changes in amplitude. Changes in amplitude can cause "breathing"
effects, thumping or clicks.
Amplitude Variations in Loop
After Loop Compression
Loop Compression smooths out amplitude variations during the loop period.
