Abstract
Cilj je narediti dinamični izenačevalnik, torej izenačevalnik, ki ne le statično spreminja frekvenčnega odziva signala, ampak se dinamični razpon posameznih pasov frekvenčnega spektra spreminja glede na razpon le-teh. Povedano drugače, frekvenčni spekter je s filtri razbit na 30 pasov, na vsakem pasu je procesor dinamičnega razpona signala (kompresor, expander, gate). Nastavitve procesorjev so preko grafičnega vmesnika povezane tako, da delovanje in uporaba dinamičnega izenačevalnika spominjata bolj na navaden izenačevalnik kot pa večpasovni procesor dinamičnega signala. Filtri so zasnovani v Matlabu, in sicer tako, da imajo linearno fazo. Enotini odzivi posameznih filtrov so zamaknjeni tako, da imajo sredinski koeficient poravnan, s tem imajo tudi vsi enak fazni zamik. Izenačevalnik in grafični vmesnik sta sprogramirana v programskem jeziku SuperCollider 3.6.

Title:A SuperCollider implementation of a dynamic equaliser
Abstract:
The goal is to build a dynamic equalizer, that is an equalizer that not only statically changes the frequency response of a signal, but the dynamic range of individual bands of the frequency spectrum is changed according to the dynamic range of themselves. In other words, the frequency spectrum is broken up with filters into 30 bands, on each there is a dynamic range processor (compressor, expander, gate ). The settings of the processors are connected through a graphic user interface in such a way that its functioning and use resembles more an ordinary equalizer than a multiband dynamic range processor. Filters are designed in Matlab in such a way that they have a linear phase. Impulse responses of individual filters are shifted so that their middle coefficients are aligned. That way they all have the same phase delay. The equalizer and graphic user interface were programmed in SuperCollider 3.6.

Keywords:dynamic equalizer, dynamic range of a signal, multiband dynamic range processor, Matlab, linear phase, graphic user interface, SuperCollider 3.6, computer science, computer and information science, diploma, interdisciplinary studies
