digital audio turns that smooth analog wave into a stair-step. again, it will never completely, truly and accurately reproduce the analog wave. we are stuck in a format with the CD that is 16-bit, 44.1KHz. higher bit-depths and sampling rates will create a stair-step that is a closer representation of the analog curve, but it will never be exactly there.
There is no such thing as a "smooth" analog wave, the "smoothness" of an analog wave is limited by the size of the molecules of the media the music is stored on. In the case of vinyl, if you look at the size of a vinyl molecule (nevermind the size of the stylus tip) and the height/width of a typical vinyl grove, the number of "steps" in a vinyl recorded is far far less than the number of steps in a 16bit/44.1kHz CD.
Of course referring to "steps" of a digital recording is misleading as well, those "steps" are not played back directly, they're used by the DAC to reconstruct a "smooth" analog waveform. It's like saying a blueprint can't ever be te same thing as a house because it's a on small piece of paper - the blueprint isn't meant to be the house, it's meant a series of instructions on how to construct the house.

But, clearly, not reprehensible in the United States of America to campaign on a platform of your ethnicity as was evidenced in the last major presidential election?

As a foreign viewer of the American presidential race I was astounded to the extent that self-promotion based on race was a factor.
Examples? Obama did everything possible to downplay ethnicity during the campaign and only brought it up when opponents tried to use his race/ethnicity (usually vis-à-vis his associations) to make political hay. There's a reason why "post-racial" was such a buzzword here last year.
What doesn't it allow other players to do (other than pretend to be iPods)? Nokia Multimedia Transfer works just fine with iTunes - in fact better, since iTunes doesn't have to be running for my E71 to sync with iTunes content.
There was a case before the Mass Supreme Judicial Court about 10 years ago where a motorist was stopped by the police. The motorist felt he was being singled-out unfairly so he secretly audio recorded the encounters. A few days later he went to the police station to file a formal complaint against the officers and submitted his recording as evidence. He wound up being arrested, charged and found responsible for violating the wiretap statute. The defendant appealed the decision up to the SJC and lost there.
I've always been torn up a little about the wiretap statute. I think it's not totally unreasonable to have some measure of protection in citizen-to-citizen interactions, especially in this age of Youtube. However I've always felt there should be an exception to this rule for recording municipal and state employees (including police) acting in their official capacity.
FWIW, there was an attempt to change the law to make an exception for recording police officers but (as one might expect) opposition from police unions killed it.
Marvel has been going downhill for a long time. So much so that I consider this deal to be part of a natural progression. Between poor writing and poor management, I haven't seen anything good from Marvel Comics since the late 90s, or maybe early 00s..
Heh, that's a funny situation for Apple to be in. I guess Apple is no longer interested in just selling you the hardware and a good OS, they want to sell you a substantial number of the applications as well.
I don't think it's about Apple wanting to see you a substantial number of apps, I think it's about Apple not wanting the core features of their phone to be based on the whims of a third party. It's kinda like the situation of Office on the Mac back in the 90's when MS threatened to kill Office which would have basically ended corporate use of Macs.
Rereading your post, I realize you specified white voters (as opposed to whites in general) so my point 'a' is moot. Point 'b' still stands though. And of course this assumes that a person's vote is an any way indicative of their racial views.
I don't know, given my experience, and the experience of other commenters, it seems reasonable to me.
One poster asserts a generality without backup, is called out for that by another poster who then goes on to make another assertion without backout and that "seems reasonable"? So be it.
You kind of seem to disagree, however.
I haven't expressed my agreement or disagreement. You can be sure that if I did, I would either support my view with evidence or indicate that it was an opinion based on personal experience.
I think we can reasonably assert at least that most white voters are not racist, since the majority of them voted for Obama.
You can assert no such thing considering that a) voters only represent a subset of white U.S. citizens, and b) McCain won the white vote (another source).
I am certain that walking through the Tenderloin is a completely different experience for a white person and a black person.
I am certain that many different things are a completely different experience for a white person and a black person.
It's sad that you ask for citations to try to deflate his argument. He doesn't need citations. He has his life experience, and you have none.
What exactly makes you think you know anything about my life experiences? (hint - I'm black and I know what it's like to be on the ugly side of a police officer with his weapon drawn).
If you think that black, asian, jewish, or any other ethnic group of people cannot be racist,
Please point to the part of my post where I said anything of the sort. That's what I though.
My comment was in response to a post that itself asked for a citation to back up a generalized statement and then itself made a generalized statement without any backup. To see anything more in that post only reflects your own biases.
I am not sure how you would even test that, would people really honestly answer a survey that asks them if they hate blacks?
Sigh. You and the anon coward both seem to have missed the point.

BTW, I am black (and I've been through the Tenderloin). And I'm not saying there aren't *any* racist blacks, I'm asking the AC to defend the statement "there are just as many black racists here as there are white." If you can't back up the statement, why make it?
"Far more sensitive hearing" depends on the frequency range. If you look at the curves on this page you can see that while dolphins are indeed far more sensitive to (aquatic) sounds in the higher frequencies than humans are, their low-frequency thresholds are pretty high.
Yes you can determine the distance by broadcasting a continuous sound by if the sonar signal is known (which it is) and running a cross-correlation on the return signal even in the process of continuing to broadcast your signal (or other vessels continuing to broadcast their signals. In fact you're liable to get a much better signal-to-noise ratio by running a long pulse train and cross-correlating the results than by using simple pulses (see MLS).
I don't know if this is how sonar was used in this case, but it can be used that way.
To the best of my knowledge, SONAR is short bursts of loud noise broken by longer periods of quiet to receive and process the return echos.
You don't need quiet to receive and process the return echo, you can use cross-correlation/cross-spectral techniques to process the return pulse even if it's buried in noise. If that wasn't the case, you could defeat sonar simply by blasting noise into the water to bury the sonar pulses.
WRT to all of the "203 decibels, OMG!" comments: water decibels aren't the same as SPL decibels.
A decibel is the logarithmic relationship between one quantity and a reference quantity. For sound pressure level, we use the RMS pressure of the sound wave compared to a reference pressure that represents the threshold of human hearing (20 microPa): 20*Log10(P/20e-6)
Other types of decibels use different reference quantities. For example, vibration velocity in the USA uses a reference quantify of 10^-6 in/sec. Sound intensity (sound power through a unit area) uses a reference quantity of 10^-12 W/m2. So comparing sad sound intensity decibels to vibration velocity decibels is meaningless without normalizing the units.
In the case of water decibels, we use pressure as we do for SPL in air, but the reference quantity is different: for water, the reference quantity is typically 1 microPa. Therefore the 203 dB in water is approximately equivalent to about 170 dB SPL in air. Of course you still can't directly compare water dB to SPL because the wavelengths of sound in water are so much longer than wavelengths of sound in air.
In any event, 203 dB in water is very loud (and obviously harmful to aquatic life as demonstrated in the articles), but not necessarily in the same way that 173 dB SPL is loud/harmful to us.
The result: a new source of money for highways and bridges badly in need of repair.' You can bet that legislators, mayors, and city councilpersons everywhere will see this as an even-better source of income than red-light cameras. You've been warned."
Why is this a bad thing? If the users of the road have to pay a little extra to maintain the road they're using, I don't have problem with it. If the money is being poured into some politician's slush fund, sure that's a problem, but reasonable use fees are exactly what's called for her. It sure beats the "selective billing" process of red-light cameras.
It's more than that. Now Apple (although probably not Amazon since they maintain they have no presence in NY) will have to collect a special tax strictly for NY residents, and pay that tax regularly to the state, and maybe file additional reports at additional expense, and no longer have the nicely uniform 99 cents/download price/image
Apple already does this in Massachusetts (our $0.99 downloads are really $1.04) and rather than fleeing MA, Apple has expanded its retail presence here.
People may or may not like the tax, but Apple clearly doesn't have a problem collecting it.
