Digital Audio: Sampling, Quantization, Bit Depth and Dither

HN calls it the gold-standard debunking of audiophile myths and the stair-step misconception, and recommends it as a primer on digital audio.

Monty Montgomery of Xiph.org gives real-time demonstrations of sampling, quantization, bit depth and dither using real audio equipment, including both digital analysis tools and vintage analog bench gear. It shows that sampled audio is not stair-stepped and corrects common misconceptions about digital audio.
