Question

Karlheinz Stockhausen used a technique where musical instruments are ring modulated with these sounds in works like Mixtur and Mantra. Hewlett-Packard’s first product, the 200A, used a Wien bridge oscillator to generate these sounds with low distortion. The iconic Roland TR-808 (“eight oh eight”) kick drum is essentially made by filtering and processing a low one of these sounds. (-5[1])The only album Aphex Twin released under his Polygon Window alias is titled for “surfing on” these sounds. These sounds are usually not used for subtractive synthesis since filtering them only changes their (*) volume, while additive synthesis works by adding these sounds together. This sound joins triangle, sawtooth, and square (-5[1])or pulse as the four main waveforms (10[1])used by synthesizers. For 10 points, name (10[1])this sound that has no harmonics or overtones, meaning that its waveform is a single trigonometric function. ■END■ (10[2])
