This means that the waveform is built \u003cbr\u003eup from a set of sine waves of various frequencies and amplitudes.  \u003cbr\u003eThe pitch of each note is defined by a sine wave at the notes’s fundamental \u003cbr\u003efrequency, for example middle-C on a piano keyboard has a frequency of 261.63Hz. \u003cbr\u003eThe harmonics, also called partials, are sine waves with frequencies that are odd or \u003cbr\u003eeven multiples of the fundamental frequency. The timbre or sound of the note \u003cbr\u003edepends on the amplitude or loudness of these harmonics relative to the \u003cbr\u003efundamental frequency. The waveform can also include sine waves unrelated to the \u003cbr\u003efundamental frequency adding to the range of sounds that can be synthesized. This \u003cbr\u003eset of sine waves of various frequencies is called the spectrum of the waveform, \u003cbr\u003ehence the term spectral synthesis. \u003cbr\u003eThe amplitude of the harmonics can be modulated in various ways to dynamically, \u003cbr\u003eand sometimes radically, change the sounds that dSpec synthesizes.\u003c\/p\u003e","brand":"gregsbrain LLC","offers":[{"title":"Default Title","offer_id":47327283642627,"sku":null,"price":385.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0764\/2818\/1763\/files\/panel_live.png?v=1760312818","url":"https:\/\/gregsbrain.myshopify.com\/products\/dspec-direct-spectral-synthesis-vco","provider":"gregsbrain Eurorack Modular","version":"1.0","type":"link"}
