Home So, for example, electric filters serve for processing of the material concrete or received on sound generators путeм подчeркивания or levellings of the selected areas of a timbre which frequently represents the most complicated world, capable to bear the information for the future composition. By the way, confuses nobody that, say, in a symphonic orchestra are used сурдины which "cut off" low frequencies and lift top, i.e. Act in a filter role and anybody does not have a doubt in целеособразности applications of these adaptations. The device the modulator задаeт the necessary frequency of fluctuation of tone, thereby transforming its "articulation". Similar приeмы we observe in usual tools. These are various ways of execution: портаменто, trills, a tremolo, фруллато and т. д. The Difference consists only that modulator possibilities allow to make over a sound much more operations, than it is to well traditional musical instruments. Besides, the modulator allows to operate a timbre by means of other timbre. For example, a human voice to modulate a timbre of any other nature, and last obediently follows all subtleties of "pronunciation" of the first.
