Summary

This paper provides a practical introduction to audio signal processing with hands-on MATLAB and Octave code examples. It guides the reader through core techniques for analyzing, filtering, and prototyping sound-processing algorithms using time- and frequency-domain methods.

Key Takeaways

• Implement basic audio I/O, preprocessing, and playback workflows in MATLAB/Octave using provided examples.
• Apply FFT and short-time spectral analysis to visualize and measure audio signal properties.
• Design and apply FIR and IIR digital filters to common audio tasks such as smoothing, equalization, and noise attenuation.
• Prototype simple sound synthesis and effect algorithms to validate ideas quickly with audible results.
• Interpret spectrograms and basic statistical measures to characterize and compare audio signals.
