Signal Processing with Free Software presents practical experiments in signal processing in order to demonstrate some possibilities for the practical implementation of signal processing techniques. To do this, the author uses free software applications, including SoX, Audacity and Visual Analyser, focusing on their uses in real situations.

The text introduces elementary signals through elementary waveforms, signal storage files and elementary operations on signals. It goes on to present the first tools of signal analysis, such as temporal and frequency characteristics, before leading on to time-frequency analysis. Non-parametric spectral analysis is also discussed, as well as signal processing through sampling, resampling, quantification, and analog and digital filtering.

The practical nature of this book with signal processing laboratory exercises makes it particularly relevant to university students and teachers in this field.
