Hi Rob,
Well, I knew your claim was unfounded, but I was willing to listen to, and
was interested in, what YOU had to say. Not what web sites have to say.
There is an irony here that you want to hold your hands over your ears and
not hear the reality of the situation. But, it is your prerogative to do
so, and not listen to someone who is a professional electrical engineer, and
who has a very lengthy resume of directly related audio research and
development history. I am very happy to discuss the topic on a technical
level with you, or anyone else. I'm even willing to debunk any "Internet
myths" or other myths on this subject you'd like to bring up. But simply
dismissing me, well, that's your loss.
The claims in the How Stuff Works website are somewhat silly and require
major suspension of disbelief:
"A vinyl record has a groove carved into it that mirrors the original
sound's waveform. This means that no information is lost."
There is ALWAYS information lost. There are many distortions that occur
with vinyl, and to ignore these distortions to make a point is disingenuous
or, or at the very least, uninformed.
"From the graph above you can see that CD quality audio does not do a very
good job of replicating the original signal."
The graph they show is not very useful. It does not take into account the
oversampling. A fair comparison would be the analog output signal from the
D/A compared to the analog signal from the vinyl.
So, the "How Stuff Works" resource is at best very misleading and very
uneducated on the subject. I'll check the other one after I get the kids
off to school.
Regards,
Austin
