If you are going to publish at 44.1 you should probably record at 88.2 or 176.4, but asynchronous sample rate conversion has pretty good performance even for arbitrary conversion ratios. Look at the datasheet for AD1896, it can convert 96 to 44.1 with THD+N way down to -120dB or better. You could probably do better than that converting in software slower than realtime.
Almost every oscillator out there uses a quartz crystal connected to a 74HCU04 inverter and a couple of ceramic capacitors. Such a thing is an oscillator, and it has very good long-term accuracy, but it has atrocious jitter, on the order of tens of nanoseconds. A good implementation would have the quartz crystal, a common-base amplifier with PNP transistors, and its own regulated power supply, with the squaring of the signal being taken care of by a comparator or, in a pinch, an inverter. A good implementation can have jitter below 1ps RMS, or looked at another way, -120dBc phase noise 100Hz from the carrier.
Analog-to-digital processes use analog filters on the input to attenuate signals above the Nyquist frequency (22kHz for CD). A 6-pole Bessel filter would not be unusual.
Hello sir, I hate to break it to you, but the front-end analog electronics and jittering timebase on the Audigy limit it to dynamic ranges of around 80dB and SNR of around 60dB, giving about the same performance as a good 20-year-old cassette deck.
Cheap studio gear can write "24/96" all over the package but achieving that accuracy digitally is very difficult and expensive. Most low-end equipment I've managed to peek inside of contain poorly implemented clocks. In a digital system the timebase is the most important factor, but Edirol and that crowd spend $0.10 on the clock. A good clock would make "96kHz" closer to the truth, but then it wouldn't be $199 anymore.
An actual 24-bit system has a theoretical Dynamic range of around 140dB but you'll be hard pressed to get better than 80dB with most gear. With analog recording there are at least two well-known foolproof methods to improve dynamic range and SNR: get a bigger tape, and run the tape faster. The dynamic range and SNR on 2", 32ips tape is amazing.
And of course tape can be driven to +9dB recording levels in some cases, but a digital system will clip hard at 0dB.
Digital is definitely the future but right digital recording has its problems. Next time you go to the record store notice how many High Resolution DVD-Audio recordings are being mastered from tapes.
Good reel-to-reel 1/4" decks fetch several hundred dollars on eBay, so you may as well. Collectors buy up recordings in that format, too, but most of the recordings currently offerend on eBay are complete crap.
The finest consumer tape deck ever produced, the Pioneer RT-909, had a frequency response to 30kHz. Studio decks that record at 15 inches-per-second have response clear out to 40kHz and beyond. A CD has response to only 22.05kHz, and even studio digital equipment has a hard time working up to 48kHz.
DOOM! GLOOM! Oh, except a 390m asteroid would not destroy the moon, or even necessarily alter its orbit (much). The moon has a mass of 7.35E22 kg! It is a very large rock.
You could, but you would be better off using the pcHDTV HD-3000 card which is designed to work well with terrestial, aka Over The Air (OTA), HDTV, "legacy" NTSC, and can legally ignore the FCC Broadcast Flag until June 2005.
You could just buy an HDTV, too, but that wouldn't have as much hacking value. I assume anyone who is interested in this hardware is also interested in experimenting with it, and the HD-3000 doesn't leave much room for that.
you could use this hardware to pull in terrestrial HDTV. Given the right RF frontend, you could also do satellite work. It's a highly useful peripheral.
There is a US company with a patent on making monocrystalline CVD diamonds. I think they can make them up to a few square inches now. There was a very popular story about them in WiReD magazine.
Yes. RSS is not doomed by popularity, it's doomed by its own naïve polling architecture. The designers of RSS certainly did not learn anything from history.
There's another assertion in this thread that VueScan is free on Linux, but AFAIK it is not. The free version watermarks all images you save. You purchase the program to remove the watermarking. So VueScan is really shareware: you can download it, but you don't get real functionality until you register.
That said I bought VueScan for Linux 4 years ago and never regretted it.
You smell bad and your mother was a five-cent hooker.
What does that have to do with anything? Oh right, nothing; just like the last line of your post.
GWB was the President and in command when NORAD failed to protect its own command headquarters from a civilian cruise missile, given an hour's notice. Nobody was fired or relieved of command. That's all I need to know about Bush's command prowess, and you conspicuously failed to address this point in your rant above.
In the 9/11 case, one person in the government had information that an attack was planned by Islamic terrorists...
That one person was George W. Bush, President of the United States of American and Commander in Chief of the Armed Forces. On August 6, 2001, he received an intelligence brief entitled Bin Laden Determined to Attack Inside the United States. On September 11, 2001, the President and the armed forces which he directly and absolutely commands had 1 hour's warning (from 8:40, when they first learned of the hijacking of AA Flight 11, to 9:37 when AA Flight 77 crashed into the Pentagon) to use the Air Force to protect command installations in Washington. He did not. Instead he read a story about a pet goat.
9/11 is not an example of organizational breakdown, it is an example of the gross and absolute malfeasance of one single person.
Lessig himself admitted in a lengthy self-flagellation that he blew it during the Supreme Court arguments. The court wanted to side with Eldred, but they were looking for a case based on economic harm whereas Lessig insisted on giving them an argument based on the limitation of Congressional powers.
Anyway your argument is not at all persuasive. The Constitution clearly limits Congressional power of copyright and patent, and it even employes the word "limited" and gives a perfectly valid reason:
To promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries
There ya go. Copyrights must be "limited" and they must "promote the progress of science and arts" whereas the Sonny Bono act satisfies neither.
No, the 1.18B is just completely wrong. Quick reality check: 100 million cars, avg 12,000 miles per year, avg 20 miles per gallon gives 60,000,000,000 gallons gas used annually. The 1.18B figure doesn't even pass the laugh test.
T-mobile is great, no support needed. I just dial *99# on my Nokia 3650, no username or password needed. Periodically the phone will reboot, crash, or hang up, but otherwise it is serviceable. It also works fine with MacOS X.
I'm sure that by "support" they mean some jackass in Timbuktu can walk you through a script over the phone. If you don't need that kind of service you should be fine.
Those suburban developers are surprisingly tenacious. There's a nuclear power station way, way, way west of Phoenix, Arizona, and I'm sure when they built it they thought "Of course nobody will live clear out here, 5 zillion miles from the city". But they were wrong, and the strip malls now extend 8 light years in all directions from the city center. So there's no safe distance where you can put the power station. You might as well just put them anywhere convenient.
I don't think that figure is quite right. The USA imports 20 million barrels per day, or 840 million gallons of oil. I don't know how much goes to transportation but I estimate your figure is low by a factor of 100.
Well I guess you are incapable of clicking on links, so I'll condense it for you. Bush's evangelical wingnut functionaries in the FDA overtured a 24-3 recommendation of a panel of physiciand, to allow emergency contraceptives to be sold over the counter. Emergency contraceptives hold the possibility of preventing millions of unwanted births and abortions. But to Bush's unthinking bureaucrats, there's just something magical about a sperm and an egg that the sky fairy doesn't want you to fuck with.
If you can't figure out why emergency contraception is interesting or important, ask your wife of your girlfriend or your sister or mother.

That isn't how they make them. The giant synthetic diamonds are made by chemical vapor deposition (CVD).

just out of curiousity, why would you run VueScan under wine when there's a native Linux version?

Living under the anti-science, anti-reason, faith-based regime of a hyprocritical, warmongering, theocratic jerk puts me in a bad mood, I guess.
