Abstract
Obrađene su osnove frekvencijske, dinamičke i vremenske obrade signala. Objašnjeni su temelji akustike prostora, te pojave koje prate širenje zvuka u prostoru: Refleksija, difrakcija, refrakcija, apsorpcija, odjek. Objašnjene su akustičke osobine prostora i objektivni akustični parametri: Vrijeme odjeka, vrijeme ranog opadanja, indeks prijenosa govora, te ostali parametri akustičke kvalitete kao što su: vrijeme dolaska, srednje vrijeme, parametri L i D. Mjereno je vrijeme odjeka u dvije različite prostorije na čemu je i temeljeno istraživanje ovog rada. Obrađena je identična snimka u programu AVID Pro Tools koja se sastoji od više kanala u obje prostorije. Analizirane su snimke i pojedini uzorci u referentnoj prostoriji. Nakon analize donesen je subjektivni zaključak o kvaliteti snimke, te je slijedila frekvencijska analiza odabranih uzoraka iz snimke. Donošenjem konačnog zaključka o kvaliteti snimke računalom je simuliran prostor pogodniji za obradu audio signala u programskoj podršci.
Abstract (english)
The basics of frequency, dynamic and time signal processing were elaborated. The basics of room acoustics and the visuals that accompany the spread of sound are explained: Reflexion, diffraction, refraction, absorption, echo. The acoustic characteristics of space and objective acoustic parameters are explained: Response Time, Early Fall Rate, Speech Transmission Index, and other acoustic quality parameters such as: arrival time, mean time, L and D. Response time is measured in two different rooms upon which this research is based on. An identical recording was processed in both rooms in digital audio workstation AVID Pro Tools. Individual samples and whole recordings were analyzed in reference room afterwards. After the analysis, a subjective conclusion was made on the quality of the recording, followed by a frequency analysis of the selected samples from the recording. By adopting the ultimate conclusion on the quality of the recording, reference room for processing audio signals was simulated in program support.
