Ой нимагу так ржать, ты сам то хоть почитал и понял, на что ссылку дал. Твой аффтар даже на первоистоник не ссылается.

3.2 Wavetable Synthesis
One of the very earliest synthesis techniques used
in computer music was periodic wavetable synthesis
[Mathews 1969] (not to be confused with sample playback
synthesis which is also called wavetable synthesis
these days). In this technique, a wavetable contains
only one period of the desired tone, sampled at a high
rate...
А вот про равнозначность аддитива и вэйвтабла:
Interpolatedwavetable synthesis is equivalent in principle
to additive synthesisemploying a digital sinusoidal
oscillator on every harmonic. In practice, wavetables
are generally computed as a weighted sum of harmonics
up to some maximum harmonic number. Thus, we
may either add the outputs of N oscillators together, or
we may add their effective wavetables together with the
same weightings to obtain a single wavetable oscillator.
