Abstract

U razvoju elektronskih glazbenih instrumenata, zapaženo mjesto pripada tereminu koji koristi dva radiofrekvencijska oscilatora i dvije antene za analognu sintezu zvuka. Instrument proizvodi ton upravljanjem s dvije ruke, pri čemu jedna ruka kontrolira frekvenciju tona, a druga njegov intenzitet. U ovom radu dizajniran je sintetizator zvuka koji radi na sličnom principu kao teremin, ali koji upotrebljava ultrazvučne daljinomjere za kontrolu visine i amplitude tona. Daljinomjeri su spojeni na... More ugradbeni sustav koji digitalizira prikupljene podatke i iz dobivenih vrijednosti određuje diskretne vrijednosti visine i amplitude tona kao temelj sinteze zvuka korištenjem MIDI sučelja. Izrađen je prototip upravljivog sintetizatora na kojemu se može svirati u stvarnom vremenu te je izmjerena frekvencijska točnost sintetiziranih tonova. Less

Abstract (english)

In the development of electronic musical instruments, a notable place belongs to the theremin, that uses two radio frequency oscillators and two antennas for analog sound synthesis. The instrument produces a tone controlled with two hands, one hand controlling the frequency of the tone and the other its intensity. In this paper, a sound synthesizer is designed that works on a similar principle as theremin, but uses ultrasonic rangefinders to control pitch and tone amplitude. Rangefinders... More are connected to a built-in system that digitizes the collected data and determines discrete values of pitch and amplitude of tones from the obtained values as the basis of sound synthesis using the MIDI interface. A prototype of a controllable synthesizer that can be played in real time was developed, and the frequency accuracy of the synthesized tones was measured. Less
