This was a very nice read. Grounded, wry, full with interesting information. Good find, @halosghost.
The article refers to a “Digital Media Primer for Geeks”, but the link doesn’t resolve. It can be found here, and some other interesting bits and bobs from the author here.
The author makes a lot of good points but when he talks about ultrasonics affecting the sound he glosses over how the analog filter would probably remove those ultrasonics. It’s possible to design the analog filter with different cutoffs and the most sensible cutoff for human ears (say 20kHz) would render this a non-issue.
