Title UREĐAJ ZA GENERIRANJE AUDIO EFEKATA Author Kristian Stanić Mentor Miroslav Vrankić (mentor)Committee member Kristijan Lenac (predsjednik povjerenstva)Granter University of Rijeka Defense date and country 2017-05, Croatia Scientific / art field, TECHNICAL SCIENCES Abstract Sintetizatori se dijele prema broju glasova koji se istovremeno izvode, te po načinu obrade signala. Monofonija ili izvođenje jednog glasa u danom trenutku koristi se kod snimanja u studiju. Polifonija ili izvođenje više glasova u jednom trenutku koristiti se kod nastupa uživo. Prema načinu obrade signala sintetizatore dijelimo na analogne (početci) i digitalne (suvremeni). Ostale vrste sintetizatora su: modularni (početci generiranja audio efekata, glomazni, skupi), potpuno varijabilni (proboj
... More na tržište), pretprogramirani (pojava memorije, tvornički memorirani zvukovi), programabilni (razne vrste memorije, glazbenik sam snima zvukove, mogućnost brisanja i ponovnog snimanja), sampleri (najbolja vrsta, snimanje originalnog zvuka, promjena parametara toga zvuka za generiranje različitih efekata), sistemi računalo-sintetizator (centralni procesor, uvođenje monitora za vizualni prikaz, velika brzina procesuiranja podataka), zvučne kartice (moderna računala, generiranje efekata u realnom vremenu, video igre). Sintetizatori su koristili različite vrste sinteze, te je na taj način svaki uređaj imao svoj specifičan način rada. Vrste sinteze koje se koriste su: aditivna, subtraktivna, frekvencijska modulacija, sinteza fazne distorzije, linearno-aritmetička, vektorska, fizikalno modeliranje, granularna, wavetable. Na samom kraju rada nalazi se predloženo rješenje realizacije sustava za generiranje audio efekata na digitalnom računalu. Gore navedeni pojmovi za realizaciju na digitalnom računalu prikazani su pomoću različitih blok shema, te opisom istih. Također je predstavljeno nekoliko primjera djelovanja sustava na obradu ulaznog signala, te rezultat izlaznog signala. U konačnici se daje pregled prednosti i mana našeg sustava. Less Abstract (english) Synthesizers are divided by number of voices that are performed simultaneously and the way of signal processing. Monophony (performance one voice at the time) is used for recording in a studio. Poliphony (performance two or more voices at the time) is used for live performance. According to the method of signal procesing synthesizer are divided on analog (beginning of signal processing) and digital (current signal processing). Other types of synthesizers are: modulars (the first devices for
... More generating audio effects, oversized and expensive), fully variables (the first commercial devices), presets (memory appearance, factory recorded sounds), programmables (many types of memory, possibility of deleting and recording sounds), samplers (the best type of devices, recording original sounds, parameter change of input signal for generating different effects), dedicated computers (central processing unit, the appearance of monitor for visual display, large speed of data processing), sound cards (modern computers, generating audio effects in real time, video games). Because of the various types of synthesis that synthesizer are used, every device have had there own way of work. Types of synthesis that can be used are: additive, subtractive, frequency modulation, phase distortion, linear-arithmetic, vectors, physical modulation, granular, wavetable. At the ned of the thesis there is suggestion of solution for the realization of the system for generating audio effects on a digital computer. Concepts for relization on digital computer written above are shown with different block schema and their description. There are also presented several examples of system operation on input signal processing and result of output signal. Finally, it is given review of advantages and disadvantages of our system.
