Dynamic changes of primary or secondary parameter
values are contributing to the morphology of the given sound events.
-
Envelopes: Parametric vectors
gliding between a number of fixed parameter values. During the
attack phase of a sound, these vectors are of a very short duration.
-
LFOs:
Low frequency
oscillators and any similar control structure of periodic-continuous sound
parameter modulation change more or less the
character of a sound.
-
Grains:
Granular sound
synthesis, various methods of sound resampling or resynthesis,
time stretching or compression algorithms, time delay effects, and similar
sound effect procedures provide important manipulations on generic sounds.
Any of those methods could transform a generic sound also into a
relatively new entity. In this case, it should be considered as a
generic method of sound production (below the level of musical parameter
control), or as a more complex algorithmic procedure (above the level of
musical parameter control).
