If you turn the samples up until you can hear the noise floor, you can easily hear the difference. Of course, at those levels, a full range signal would launch your speaker cones out of the cabinets. So is that a fair comparison of 16 vs 24?

There are any number of ways to cheat an ABX test to your own satisfaction. If the goal is to delude yourself, you'll probably succeed.

Indeed. One of the overlooked but highly important issues with sampling rates is that although you can represent up to Nyquist in a periodically sampled signal, that is the limit for infinite length recordings. For finite-length recordings, it isn't all or nothing, represented perfectly or not at all -- instead the uncertainty (read: representation error) increases as you approach Nyquist.

Too bad Shannon and Nyquist are dead. It seems they've completely misunderstood the math. How embarrassing they passed on before you could correct their mistake. Now they'll never know.

Truthiness refers to a specific kind of lie-- a lie that sounds true, and that a large segment of people really want to be true. The kind of thing that's close enough to true for AM radio talk show hosts.

And now... I'll get off your damned lawn. Don't forget to take your teeth out before falling asleep.


Submission + - Why Distributing Music As 24-bit/192kHz Downloads Is Pointless (

An anonymous reader writes: A recent post at provides a long and incredibly detailed explanation of why 24-bit/192kHz music downloads — touted as being of 'uncompromised studio quality' — don't make any sense. The post walks us through some of the basics of ear anatomy, sampling rates, and listening tests, finally concluding that lossless formats and a decent pair of headphones will do a lot more for your audio enjoyment than a 24/192 recordings. 'Why push back against 24/192? Because it's a solution to a problem that doesn't exist, a business model based on willful ignorance and scamming people. The more that pseudoscience goes unchecked in the world at large, the harder it is for truth to overcome truthiness... even if this is a small and relatively insignificant example.'

Submission + - Device Could Make Ships 'Invisible' to Waves (

An anonymous reader writes: The weird science of invisibility has entered uncharted waters. By altering the sea floor in just the right way, it should be possible to hide an object floating on the sea from passing waves, a fluid mechanician predicts. The technique might help to protect ships and floating structures from rough seas. And because the scheme works entirely differently from the "cloaks" developed to hide objects from light and other electromagnetic waves, it breaks new ground for research.

Submission + - Dimensions go "poof" in quantum gravity (

techbeat writes: Forget Flatland, writes New Scientist. Several different quantum gravity theories all predict the same strange behaviour at small scales: fields and particles start to behave as if space is one-dimensional. It's an observation that could bring together several disparate attempts to unite quantum mechanics and general relativity. To explain how dimensions could vanish, Steven Carlip at the University of California, Davis turns to the idea of "quantum foam", in which quantum fluctuations alter the geometry of space-time, rendering it choppy and inhomogeneous at small scales.

Submission + - France Could Be Months From Going Dark on the Web ( 2

mykos writes: According to a report from PCINpact one of the major ISPs confirmed that the first batch of IP-addresses was submitted just a few days ago. This is the final step before alleged file-sharers receive warning letters. The scope of the operation is mind boggling. The copyright holders will start relatively ‘slowly’ with 10,000 IP-addresses a day, but within weeks this number is expected to go up to 150,000 IP-addresses per day according to official reports. The Internet providers will be tasked with identifying the alleged infringers’ names, addresses, emails and phone numbers. If they fail to do so within 8 days they risk a fine of 1,500 euros per day for every unidentified IP-address. To put this into perspective, a United States judge ruled recently that the ISP Time Warner only has to give up 28 IP-addresses a month ( 1 per day) to copyright holders because of the immense workload the identifications would cause.

Submission + - VC Calls Out Ballmer, Bezos on WA State Income Tax

theodp writes: Venture capitalist Nick Hanauer, one of's earliest backers, is a staunch supporter of the proposed WA state income tax that's opposed by Steve Ballmer and Jeff Bezos (to the tune of $200,000). In addition to a little name-calling ('Bezos has been a libertarian since I met him and Ballmer is a typical Republican'), Hanauerhad had some other choice words on the matter: 'None of the people who are investing money to oppose I-1098 would have the courage to actually move themselves to a place with limited government, no taxation and no regulation,' he said. 'Should Mr. Ballmer or Mr. Bezos need to move their families to another country, they would absolutely choose a country like Canada or New Zealand or Germany or France with higher rates of taxation, more regulation and more activist government than we have in the U.S. Mr. Ballmer and Mr. Bezos would not move their children to the Congo or Afghanistan, countries with low rates of taxation, no regulation and limited government.' Perhaps Hanauerhad will cut the pair some slack after reading that Ballmer is down to his last $13.1 billion, and Bezos is trying to make ends meet on $12.6 billion. BTW, Bill Gates — still the wealthiest American according to Forbes — reportedly supports the income tax like his old man, although a Microsoft spokeswoman indicated that the Gates' view isn't shared by a number of senior Microsoft execs who 'are concerned about the impact I-1098 will have on the state's ability to attract top tech talent in the future.'

Submission + - China Embargos Rare Earth Exports to Japan (

Hugh Pickens writes: "The NY Times reports that the Chinese government has placed a trade embargo on all exports to Japan of a crucial category of minerals used in products like hybrid cars, wind turbines and guided missiles. China mines 93 percent of the world’s rare earth minerals, and more than 99 percent of the world’s supply of some of the most prized rare earths, which sell for several hundred dollars a pound. The embargo comes after a dispute over Japan’s detention of a Chinese fishing trawler captain whose ship collided with two Japanese coast guard vessels as he tried to fish in waters controlled by Japan but long claimed by China. The Chinese embargo is likely to have immediate repercussions in Washington. The House Committee on Science and Technology is scheduled to review a detailed bill to subsidize the revival of the American rare earths industry and the House Armed Services Committee is scheduled to review the American military dependence on Chinese rare earth elements."

Submission + - Stallman crashes talk, fights 'war on sharing' (

schliz writes: Free software activist Richard Stallman has called for the end of the 'war on sharing' at the World Computer Congress in Brisbane, Australia. He criticized surveillance, censorship, restrictive data formats and software-as-a-service in a keynote presentation, and asserted that digital society had to be "free" in order to be a benefit, and not an attack.

Earlier in the conference, Stallman briefly interrupted a European Patent Office presentation with a placard that said: "Don't get caught in software patent thickets". He told journalists that the Patent Office was "here to campaign in favor of software patents in Australia", arguging that "there's no problem that requires a solution with anything like software patents".
