Description Generates a Wavetable from a list of partials with matching amplitudes and phases. Partial, here, refers to a particular sine wave in the harmonic series (see: Harmonic vs. partial). If you want to generate a single sine wave, suitable for playing a single tone of a particular frequency in an Oscil, you could use this code:
But what this method lets you do, is create a Wavetable that contains several different partials, each with a particular amplitude or phase shift. For instance, you could create a Wavetable that plays two pitches an octave apart like this:
If this is something you want a particular instrument you write to do, then creating a Wavetable that already contains the octave and using that in an Oscil will be less computationally expensive than creating two Oscils and setting their frequencies an octave apart.
