Implementation and Test of FIR and IIR Audio Filtering on the DSP Platform

Abstract

Implementing FIR and IIR filtering functions according to different structures, considering both floating-point and fixed-point representations. The fixed-point versions will then be tested in real time, implementing an audio loop. Afterwards, several experiments were conducted with the DSP techniques, such as linear and circular buffers and fixed-point implementation. Moreover, implementing and testing an audio compression/decompression algorithm on the DSP platform has been performed.
