Abstract

Rad opisuje sustav za digitalnu obradu signala zasnovan na BeagleBone Black platformi. Središnji dio sustava je BeagleBone Black koji prikuplja podatke sa audio kodeka, komunicira sa sklopovljem i pokreće mrežni poslužitelj koji korisniku omogućuje kontrolu digitalne obrade signala. BeagleBone je ugradbeni računalni sustav zasnovan na Linux platformi, a programska potpora za obradu signala koristi najnoviju Debian distribuciju. Dodatno, rad opisuje implementacije ujednačivača i digitalnih zuvčnih efekata koristeći filtre konačnih i beskonačnih impulsnih odziva.

Abstract (english)

This thesis describes a system for digital sound processing based on BeagleBone Black platform. The central point of the system is BeagleBone Black board, which collects data from audio codec, communicates with peripheral hardware, and runs a web-server which enables user control of digital signal processing algorithms. BeagleBone Black is a Linux based embedded system, where the software for real-time audio processing runs on the latest Debian Linux OS distribution. Additionally, the paper describes implementations of equalizer and digital sound effects using finite and infinite impulse response filters.
