A Computerphile video transcript explaining oversampling in digital signal processing through an audio context. It covers the Nyquist-Shannon theorem, how aliasing occurs when frequencies exceed half the sample rate, and why this causes problems in audio effects like saturation. The solution demonstrated is zero-padding (inserting zeros between samples to double the sample rate), followed by a low-pass filter to remove the mirrored frequency artifacts. Practical demonstrations using plugin software show how oversampling eliminates aliasing distortion in harmonic generation.
