Procesador digital de señales aplicado en sistemas de refuerzo sonoro implementado en una placa comercial de bajo costo

Abstract

This paper presents the design of a device aimed at correcting disturbances in a sound reinforcement system. The fundamental component of this system is the speakers, which are typically designed for ideal conditions such as spatial location and acoustic reflections in a specific venue. However, physical variables such as temperature, dimensions, phase cancellations, and construction materials significantly affect their performance. To mitigate these issues in the original signal, processes such as equalization, compression, and delay are employed. Currently, these processes are integrated into a single system known as an "integrated speaker management system." However, the high cost of these systems hinders their implementation in budget-constrained installations, which often face significant challenges in this regard. This paper aims to present the design of a device featuring stereo analog audio input and two processed audio output channels to effectively support sound reinforcement systems.
