20.500.12556/RUL-163974 Digitalna izvedba klasičnih zvočnih učinkov za uporabo pri nastopih z živo glasbo Digital implementation of classical sound effects for live performances Magistrsko delo se ukvarja s principi delovanja digitalnih efektov, ki so tako v analogni kot tudi v digitalni obliki nepogrešljiv del opreme večine glasbenikov, predvsem kitaristov in basistov. Digitalni efekti oziroma pedali, kot jih je poimenovala industrija, so majhne elektronske naprave, ki na svoj način vplivajo na zvok instrumenta. Spreminjano lahko barvo zvoka, dodajajo nove zvoke, ali pa zvok spremenijo v nekaj čisto neprepoznavnega. Fokus magistrske naloge je predvsem na efektih za žive nastope. Za obdelavo signalov se v industriji pogosto uporablja namenski digitalni signalni procesor, vendar magistrsko delo prikazuje bolj univerzalno rešitev, ki se lahko prenese tudi na druge naprave. Tako smo uporabili precej zmogljiv procesor, ki nam je omogočil večjo kompleksnost algoritmov. Poleg tega lahko na tak način zgradimo sistem z zgolj dvema komponentama: s procesorjem za izvajanje algoritmov in s kodekom, ki nam poenostavi zajem in rekonstrukcijo signala. Naloga je izvedena na razvojni plošči STM32H750B-DK nizozemskega proizvajalca STMicroelectronics, ki že vsebuje vso omenjeno elektroniko. Dodatno ima na sprednji strani še RGB LCD zaslon na dotik, ki smo ga uporabili kot uporabniški vmesnik za konfiguracijo efektov in prikaz njihovega stanja. Poudarek naloge je na dizajniranju in implementaciji časovno diskretnih sistemov. Zgrajen sistem služi kot osnova za nadaljnjo implementacijo v dejanski efekt za uporabo na odru. Je dinamična platforma, ki omogoča tudi nadaljnje nadgradnje za odkrivanje razlik med efekti ter morebitno izboljšanje ali odkrivanje novih. This master’s thesis explores the principles of digital effects, which, in both analogue and digital forms, are an essential part of the equipment of most musicians, particularly guitarists and bass players. Digital effects, also referred to as pedals in the industry, are small electronic devices that alter the sound of an instrument in their own unique ways. They can modify the colour of the sound, add new sounds, or transform the sound into something completely unrecognisable. The thesis primarily focuses on effects in live performances. The industry often relies on a specific digital signal processor for signal processing. However, the thesis presents a more universal solution that can be transferred to other devices. Thus, a relatively powerful processor was used, which allowed for increased algorithm complexity. Additionally, a system can be built using just two components: a processor to run the algorithms and a codec to simplify signal capture and reconstruction. The research was conducted using the STM32H750B-DK development board by the Dutch manufacturer STMicroelectronics, which already includes all the aforementioned electronics. Furthermore, the development board features an RGB LCD touchscreen on the front, which was utilized as a user interface to configure effects and display their status. The focus of the master’s thesis lies on the design and implementation of discrete-time systems. The system developed as part of this thesis serves as a foundation for future implementation into real-world effects that could be used on stage. It is a dynamic platform that also allows for further upgrades to explore the differences between effects and possibly to improve or even create new ones DSP avdio učinki procesiranje signalov LTI sistem STM zajem rekonstrukcija DSP audio effects signal processing LTI system STM capture reconstruction true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2024-10-15 09:50:00 2024-10-15 09:50:09 2024-12-03 14:34:13 0000-00-00 00:00:00 2024 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 62660 217515779 Zivic_Tadej_-_Digitalna_izvedba_klasicnih_zvocnih_ucinkov_za_uporabo_pri_nastopih_z_zivo_glasbo.pdf Zivic_Tadej_-_Digitalna_izvedba_klasicnih_zvocnih_ucinkov_za_uporabo_pri_nastopih_z_zivo_glasbo.pdf 1 AB8D6A5EB0D65CF5084E45D45DA95A8D bdf5eeed81e064690a15ce3e398bb710e4b7153272d09729c5aff01b37f29514 deae71d8-8ac9-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=194002 Fakulteta za elektrotehniko 0 0 0
