Analýza zvukového signálu pomocí programu Matlab

Abstract

This thesis is focused on processing and evaluating of infrasound and low frequency sound signals. The aim is to create graphical user interface using Matlab through which one can analyze audio signals stored in WAVE format. Analysis tools include methods for the signal analysis in the time domain, in frequency domain and combination of both. In addition to these methods for analysis is possible to done play audio recordings or filtering. Within the implementation of graphical environment are used integrated methods of Matlab or individual available functions, which make up the algorithm of required method. Based on the findings the Matlab can be considered as a suitable tool for visualization and analysis of audio signals.
