Digital sound starts to suffer all sorts of aliasing and other related problems as you approach the limits.
eg. How does a CD store the difference between 22kHz square/sine/sawtooth waves?
It can't. It will even have trouble distinguishing them at 11kHz - well within the hearing limit.
Other problems: How do you even sample a 22kHz sine wave? Where do you put the sample points? How wide should they be? You can't use the beautiful 'dot' samples shown in the theory books - if the phase is wrong you might sample the zero-crossing points and not see any signal (in fact there's only one phase which would see the full signal - 90 degrees out of phase with the sampler would give a quieter output).
CD sound is FAR from "Right, that's that sorted out then...". On the contrary, It's on the very limit of audio fidelity, only just good enough. To get a good result you need to sample at much higher frequency/resolution then process it down but even then the exact waveform of the high frequency waves is lost (you can argue over whether those differences are audible, I think they are).
These days we ought to be listening to 96kHz/24bit, the technology to reproduce it is ubiquitous. The problem is the MAFIAA doesn't want us to have it.
But... if there's no legal/technical measure that can stop it then should we waste time/money taking away everybody's rights? Nope.
The economics of 'free' does work so long as the cost of reproduction/distribution is also zero. Which it is.
All you have to do is give a better service than the pirates and provide extras which can't be transferred down a wire. Believe it or not people are prepared to pay for official merchandise, accessories, bling, etc. As for concerts...they go crazy for those!
Yes, I'm sure they though of the "I can be famous/rich and divert the attention of the masses at the same time" angle...
What I'm doubting is that they ever devoted a single neuron to the idea of protecting one of the most historically valuable places on earth from looters.
Most cats are trained at a very young age by their mother to use a litterbox.
My cats never knew their mother but they still figured it out by themselves. They're eight years old now and never did anything outside the litter tray. Not once.
Slashdot Mirror
and analog has similar limitations..
Yep.
But it has no theoretical limitations. In theory Analog can be perfect, it's just a case of spending enough money.
(Not that I'm advising that path - the difference would probably be difficult to hear)
This "difference" you speak of doesn't exist. It's a product of your misunderstanding of waves.
I understand waves perfectly, thanks.
My statement that a 44kHz sampling rate can't reproduce the differences between 22kHz sine/square/saw is a simple fact.
On the contrary, CDs are perfect.
Really? So why do professionals/studios use higher sampling rates?
The master copy is at a much higher bitrate/resolution than can be transferred to a CD.

+1 informative, thanks for posting that.
But...if all that's true then how come we're still voting on it nearly two years later?
I got scanned last year in Manchester, UK.
Atheism isn't a religion.
No, it was a ship. I've seen it on the WWII channel.
Well...if you'd read the article in your mad dash for first post you'd know what it was.
You don't even need to read the whole thing, the first line would have done the trick.
Moron.
Yes, *you*. You're a moron.
How can you be so sure? Have they tried it yet...?
FWIW I suspect the real business model is somewhere in between those two extremes.

Here's an article for you
Yes, I'm sure they though of the "I can be famous/rich and divert the attention of the masses at the same time" angle...
What I'm doubting is that they ever devoted a single neuron to the idea of protecting one of the most historically valuable places on earth from looters.
Some have even suggested that it was on purpose.
Nah, that would require some sort of planning.
Never attribute to malice that which can be explained by stupidity or whatever the expression is.
A politician listening to the people is now "a PR move"...?
Let's hope some other politicians are paying attention.
Yeah, but the cat's out of the bag. Politicians have seen they can get positive vibes/votes by opposing it.
It's not used because of Guy Fawkes, it's used because a movie called "V for Vendetta".
it was never about protecting artists, it was never about doing the right thing, it was always about control
Strangely enough, Megaupload was shut down just when it was about to launch a music service that would have paid 90% of earnings to artists.

Style, baby, style...
It's about much, much more than that:
Oh, bullshit. Talk abotu cherry picking... for every feature that's listed as 'similar' there I could list another one that isn't.
Apple:
Home button is round
Doesn't have camera on front
Doesn't have 'back' and 'menu' buttons
Samsung:
Home button is rectangular
Has camera on front (top right)
Has 'back' and 'menu' buttons
etc.
The profile is even better - it's nothing like an iPhone from the side. But you missed that.
the 4x4 grid of icons with another row of 4 at the bottom is a bit of a rip off, but a novel invention worthy of a patent?
That wasn't even Samsung, it was "Android".
Yeah, but they didn't. And Apple sued anyway.
Presumably just to be assholes - why compete on features/price when you've got money to burn on lawyers?
both Apple and LG could have gotten their inspiration from the same source.
...so could Samsung.
So by their logic: If you make $160k/year you can afford a drug which costs $294k/year...?
