Abstract

Obrađeni su temeljni principi sinteze zvuka. Objašnjeni su sastavni dijelovi sintetizatora zvuka: Generatori signala, filtri i njihova realizacija algoritmima, algoritmi za pojačanje, modulacija ovojnice, nisko frekvencijski oscilator, ovojnice audio signala i MIDI modulacija. Objašnjene su značajke virtualne studijske tehnologije na kojoj se temelji dano rješenje. Elaborirana je tehnička pozadina digitalne obrade signala, kao i mogućnosti korištenja u programskom okruženju. Ostvarena su dva programska rješenja sintetizatora zvuka od kojih jedno učitava i reproducira .sf2 datoteke, a drugo se temelji na sintezi pomoću valnih tablica. Detaljno je objašnjen postupak programiranja VST dodataka s dodatnim fokusom na svojstvene objekte grafičkog korisničkog sučelja i frekvencijsku obradu signala.

Abstract (english)

The main principles of sound synthesis are elaborated. Main components of sound synthesis are explained: Signal generators, filters and their realization with algorithms, amplifiers, modulations, low frequency oscillator, envelopes and MIDI modulation. Features of virtual studio technology on which the given solution is based on are explained. A technical background of the digital signal processing is elaborated, so as its usage in the programming frameworks. Two program solutions of sound synthesizers are given, one of them is based on reading and reproducing .sf2 files and the second one is based on wavetable synthesis. Detailed explanation of VST plugin programming is given along with focus on custom GUI objects and signal processing in frequency domain.
