What will I learn?
This short, practical Signal Processing Course gives you the skills to inspect, clean, and optimize speech audio with confidence. Learn digital audio basics, waveform and spectrogram analysis, and key metrics like SNR. Practice real-world filtering, spectral subtraction, compression, and de-essing using MATLAB or Python, then document results with clear, reproducible reports and well-structured listening evaluations.
