Analyzing YouTube's Audio Fingerprinter 116

Posted by timothy from the streeeeeehtch-thiiiiingsss-ouuuuuut dept.
Al Benedetto writes "I stumbled across this article which analyzes the YouTube audio content identification system in-depth. Apparently, since YouTube's system has no transparency, the behaviors had to be determined based on dozens of trial-and-error video uploads. The author tries things like speed/pitch adjustment, the addition of background noise, as well as other audio tweaks to determine exactly what you'd need to adjust before the fingerprinter started mis-identifying material. From the article: 'When I muted the beginning of the song up until 0:30 (leaving the rest to play) the fingerprinter missed it. When I kept the beginning up until 0:30 and muted everything from 0:30 to the end, the fingerprinter caught it. That indicates that the content database only knows about something in the first 30 seconds of the song. As long as you cut that part off, you can theoretically use the remainder of the song without being detected. I don't know if all samples in the content database suffer from similar weaknesses, but it's something that merits further research.'"

Spotify Releases a Linux-Only Client Library 96

Posted by timothy from the you-and-you-and-definitely-not-you dept.
f0rk writes "Spotify, a popular music streaming service, has just recently released libspotify. An official, binary-only, only for subscribers, library to 'enable and inspire you to build some really cool stuff.' The first release only has support for x86-32 Linux, the only major platform Spotify does not run on. It looks like the Spotify team is trying to be nice to the Linux community and hope someone will use their restricted binary-only library to write a Linux client."

That's not a good comparison, as the Game Boy Advance was wildly different in capabilities from the Game Boy Color. Meanwhile the DS, DS Lite and DSi are essentially the same system.

So it's true - Nintendo is developing better business sense with time!

Apple Shifts iTunes Pricing; $0.69 Tracks MIA 429

Posted by kdawson from the where-it-comes-down-that-is-not-my-department dept.
Hodejo1 writes "Steve Jobs vowed weeks ago that when iTunes shifted to a tiered price structure in April, older tracks priced at $0.69 would outnumber the contemporary hits that are rising to $1.29. Today, several weeks later, iTunes made the transition. While the $1.29 tracks are immediately visible, locating cheaper tracks is proving to be an exercise in futility. With the exception of 48 songs that Apple has placed on the iTunes main page, $0.69 downloads are a scarce commodity. MP3 Newswire tried to methodically drill down to unearth more of them only to find: 1) A download like Heart's 34-year-old song Barracuda went up to $1.29, not down. 2) Obscure '90s Brit pop and '50s rockabilly artists — those most likely to benefit from a price drop — remained at $0.99. 3) Collected tracks from a cross-section of 1920s, '30s, and '40s artists all remained at $0.99. Finally, MP3 Newswire called up tracks in the public domain from an artist named Ada Jones who first recorded in 1893 on Edison cylinder technology. The price on all of the century-old, public-domain tracks remained at $0.99. (The same tracks are available for free on archive.org.) The scarcity of lower-priced tracks may reflect the fact that the labels themselves decide which price tier they want to pursue for a given artist; and they are mostly ignoring the lower tier. Meanwhile, Amazon's UK site has decided to counter-promote their service by dropping prices on select tracks to 29 pence ($0.42)."

I wouldn't take Vista for free but I happily paid a $500 'logo tax'

Why can't people just prefer apple, and not be fanatical about it? Oh, right, because then that wouldn't justify the increased expense.

Personally I like the hardware and design of the MacBook Pro, the software is nice too, but for me it's not worth the extra coin.
