Not sure how many of you share mp3's regularly, but have you noticed a sharp increase in noise induced mp3's?
Over the past 2 weeks I've noticed a very weird trend.. about 40% of the songs I download are full of ear screeching noise. Yet, they are the same
file size and length of the working version of the song. Let's call them Noise.mp3 and GoodSong.mp3.
Example mp3: www.lockedonhosting.net...
Basically, what you hear is the song, then about 10% into the song you hear different tones of induced noise, then the remaining 10% is music again.
The weird part requires me to talk about my mp3 file format research some.. Basically, the higher the pitch during recording, the higher rate your
computer will process the data it hears (bitrate). In order to have the file sizes of Goodsong.mp3 and Noise.mp3 to be the same, you would have to
fluctuate the pitch of noise throughout the mp3. Try it for yourself. Open you trusty windows Recorder, talk into it, save it, then make a new file
and scream the same sentence, save it, and compare the filesizes.
Big deal, some kid is ruining songs by adding a carefully calculated amount of noise to it?
It is a big deal if you know anything about peer-to-peer sharing. Allow me to explain..
Basically, if I download Noise.mp3 thinking its Goodsong.mp3, I'll download the song, and listen to it shortly.. Great, its the right song, onward to
my next download. Then after downloading 15 songs, I'll proceed to burn them to a CD to listen to in my morning hour commutes. About 30seconds into
the song I'll hear the noise.. Damn, this CD is ruined now.. I'll have to remake it. In the meantime, while you're at work, leaving your trusty
WinMX open, you share Noise.mp3 to 97 people. Maybe 50% of these people will realize its junk and proceed to look for a better version. The other
50% won't realize it until they hear it in their car or radio and have possibly already shared it to another 1000ish people. Eventually, people
rename the mp3 to better suit their mp3 portfolios and continue to share the corrupt song as a new file name. Rinse and repeat to another 5000 people
and before you know it, theres 14 different versions of the same noise.mp3 flying through peer-to-peers.
So what, some kid is bored and is ruining a few songs?.. but..
It's just not a few songs. It's hundreds of songs. Different singers, different genre. Over the past week, between my roommates, I've downloaded
well over 250 songs. At least 90 of those 250 songs are junk with the same noise. A fluke? Doubtful.
RIAA claimed they would execute an attack on the peer-to-peer networks a few months ago. RIAA not being dumb, knew this could not include any illegal
activities such as flooding or hacking. But theres nothing illegal about sharing ruined mp3's. Could RIAA be sharing and spreading noise induced
mp3's to try and make legit song swapping near impossible?
