There's a difference between a look up table ("LUT") and a wavetable...
LUTs are definitely used for digital oscillators when you don't have
enough
available power to calculate the wave in real time or when you want to
generate
an arbitrary function. A LUT is really just a list of precalculated wave
values
for one complete oscillation. (For some symmetrical waves, the LUT may
only
list the first half or first quarter of the wave.)
A wavetable is a series of such precalculated waves. For sound
generation, the
cool thing about that is you can choose which wave or waves you want to
use for
a particular sound. You can sweep through part or all of the table to get
a
particular sound and/or morph from one wave to another over some period of
time
while interpolating between the two...
