Sampling/Time Resolution - In search of sources Options

[FreaqyFrequency]

Greetings all,

I've been lurking on these forums for about the last year, and I finally signed up today to pick the brains of some of the more knowledgeable individuals here.

On Saturday, I'm giving an 8 minute informative speech on the essential elements of digital audio (PCM to be exact, leaving DSD out given the time limit), why it was a logical progression from analog recording and storage technology, and a brief sketch of lossy/lossless implementations of it.

My primary objective at this point is to get a rock solid source, stating that (and why) any sampling rate is able to capture a given bandlimited source with perfect time resolution (ignoring frequency response and filtering in this case, dealing only with time). I was encouraged to touch upon this point in particular because of a presentation I found on YouTube a few months back, whose essential message was "Digital is bad because you hear the music as packets rather than as an analog waveform" and was advocating that everyone dispense with their digital media and go get a turntable and vinyls. My intent is to disprove the "packets" notion, and this source is the closest I have seen to doing that as of now:

If anyone could supply further documentation (or their own findings/conclusions on the matter), that would be most appreciated. Thanks!

Again, many thanks for all the replies, extremely informative stuff. The number of hits this has gotten in the time it's been up absolutely makes my jaw drop. This doesn't happen on any other forum I actively participate in.

In light of the last two replies concerning my audience, it'd probably be prudent to note at this point that this is a basic college Public Speaking course. My main objective is going to be capturing and holding the audience's attention on my topic; they will not (generally) have a clue about any of the technical details I'm going to be getting into, which is why I'm going for brevity and for concise information that is most effective to my end. I may have one or two classmates ask me for further information on something (if I get massively lucky), but I highly doubt that any of them will have the expertise (or the desire) to challenge me on anything in particular. This request for sources on this specific issue is mainly for preparedness, in case someone down the line tries to say "Well, CD isn't good enough because you only get 22.7 µs of resolution per sample; there must be information missing there." I've seen this stuff on various audiophilia-centered forums, with other arguments coming in such as "Some instruments have rise times as low as 10 µs", yadda yadda...I'm sure you're all quite well aware of the type, so I won't go on. ;)

All an attempt to arm myself with knowledge, especially when it is so readily available in this age.

HA is especially invested in providing extra cups to those mules/horses/whathaveyou who have led themselves to water and are obviously willing to drink.

I, too, like that analogy—and dhromed’s!

This sounds like an interesting presentation that will clarify the issue and/or dispel myths for the audience, so I’m glad HA has helped you to find good sources, and I hope it goes well for you! recording or it didn’t happen
