The Truth about D/A and A/D conversion and Digital Media Primer

[rbbert]

The term “propaganda” is typically used to describe something misleading. Both videos, however, show reproducible, scientific experiments based on mathematically proven (i.e., demonstrated) theorem such as the Nyquist-Shannon Theorem (Nyquist–Shannon sampling theorem - Wikipedia) which in turn uses Fourier transform (Fourier transform - Wikipedia). The Fourier transform have been around since the 19th century; the Nyquist-Shannon Theorem was mathematically demonstrated/proven (Mathematical proof - Wikipedia) in 1930s. Actually, to label or suggest that such scientific evidence is “propaganda” without providing any scientific backup does strike me of propaganda.

First, most of this is engineering, not science, but regardless that is not really my problem with it. My problem comes with relating the digital engineering to audible effects (perception) where there is really no science at all. And there is no f___ing way I am going to watch a 30 min video; if there is some scientific evidence presented there not on his website please let me know
