Insights from the Computerphile episode “Oversampling Data (Explained with Audio) - Computerphile”, published April 9, 2026.
When digital audio processing creates harmonics that exceed the Nyquist-Shannon sampling limit, they 'mirror' back into the audible spectrum as harsh, inharmonic noise known as aliasing. Oversampling solves this by increasing the sample rate and using low-pass filtering to remove these artifacts, ensuring high-fidelity sound reproduction.
