Example #2 - 440hz Full Spectrum at Diminishing Magnitude
Leaving the DAC engaged and A440 selected on the piano keyboard, hit preset #3, the third box from the lower left in the Pitch window. This preset engages all upper partials at diminishing magnitude. This phenomenon is common in real-world instruments and sounds in general, where the lower partials hold greater energy and the upper partials decrease in strength (though sometimes, surprisingly, the lowest partial might be very weak, the so-called "missing fundamental").
Note the complex shape of the string. A larger bump is surrounded by subsequent peaks and valleys corresponding to additional partials. This bump will travel along the string, flip over, and travel back. On a piano, that bump on the string is created by the hammer’s initial impact on the string; on a guitar, the pick creates the initial impulse, and so on.
Try toggling different partials, drawing different overtone profiles, and choosing different pitches. Notice how distances and amplitudes change across the spectrogram, sonogram, and string animation.
