Music Meets Steganography
austad writes "Wired is running a story about how Aphex Twin has encoded a face into one of his songs. The face is visible when viewing the sound through a spectrograph. This is probably something I wouldn't want to see when coding in a dark room at 3AM. Sorry boys and girls, you have to buy the CD if you want to see it, encoding of the song into a lossy format destroys the image."
maybe a reason to buy the cd? even if you rip it at 320k/s though? what about burned cd's that'll keep the quality oh yeah, FP!

This is one of the ways musicians can boost sales and get more CD's out: include special features in the encoding. This a) doesnt hurt people who just want the music and/or get screwed over by copy protection, b) doesn't force the consumer to buy anything specific (i.e. hardware, or even the CD in the not-as-legal sense of it) and c) adds something cosmetic, pointless, but nonetheless cool.
I am !amused.
Just don't encode it into a lossy format. Geez. Since when did music on the internet == mp3?
scare the living SHIT out of me alone in the oplab at night...
I've had this CD since it came out -- you can definitely tell what part of the song contains the image. I tried various visualization programs but couldn't get anything too meaningful.. guess I shouldn't have given up.
Find more info about the Aphex face, as well as some software to do same thing yourself
here.
Additionally, more information on it can be found here
encoding of the song into a lossy format destroys the image."
I have an mp3 encoded @192kps, using the Nullsoft tiny fullscreen plugin displays the image just fine (its at the last few seconds of the 2nd track of the Windowlicker EP.
I got quite enough of that watching the "Come to Daddy" video, thank you.

I thought it was Stegosaurus! Jackass.
And you are a doorknob.
Interesting way to get people to buy CDs instead of downloading them... how many people would actually download a song of Britney Spears' if pictures of her came with the songs that you buy? Yeah, the RIAA should just try this...

It's possible to see hidden images in the second Aphex Twin windowlicker track. Take a look here for instructions, then visit this site for a quality screenshot.
Before reading the article I thought it was a picture in the 44khz waveform and MP3 might lose the high frequencies, but "His discovery can be reproduced with a sample of the song and some spectrographic software, which displays the different frequencies of the song as a graph against time."
Isn't storing frequences exactly how the compression works?
The image is not destroyed -- it just morphs into an image of Jack Valenti.
No, it's not.

This is news?
I always see faces when listing to Aphex Twin if I sit there for long enough... although sometimes it helps to be in the right frame of mind.

no, it's steganography.

So, really, you'd have to dedicate some of the CD to irritating noise, like Aphex Twin must have done.
Some of the CD? Have you ever listened to Aphex Twin?
Random out-of-context data is probably an improvement.
While in college I rewired my old monitor from an Apple II. I think it was called an Apple III Monitor for some reason. Anyhow, I ran hooked my speaker wires up to the coils that controled the beam in the CRT. This caused it to draw funky patterns. One particular Led Zeppelin track would draw a guitar on the screen.
Unfortunately the instrument being played was a harmonica. Strange that a harmonica would draw a guitar.
Nobody would believe me when I told them this, but everyone willing to make a trip up to my room left as a believer.
I have since written a simple WinAmp plug-in that emulates this effect. The analog way is much more neato though.

The face will be seen when the song is shared as a .wav file.
.wav file.
It is not even needed to share the whole 40 MB.
If you need to listen to the music, use the mp3 file.
If you need to see the face, download a 5 sec (mono?)
Or just buy the CD (If you like the music).
Christian Music will have crosses, doves, and christian fish encoded into the signal, which will probably improve the music.
Gothic music will encode pentagrams, broken crosses, and tributes to Jack Chick, but nobody will notice because it's all screaming anyway.
Country music will include images of pickup trucks, cowboy hats, and liquor bottles, but since country fans are all hicks, they will never be discovered.
The RIAA will mandate that all music have encoded into it pictures that won't survive reencoding, but that, when translated to mp3, will crash your computer.
Nice to see Richard mentioned on /.
He is huge in the "geek community" there are various shrines located around the MIT campus dedicated to the man . . .

Who has a spectrograph? Not me...
The article says the guy who found the face when he was playing around with WinAmp one evening, soooo, presumably you can get a spectrograph plugin for winamp.
You can download the 9 second wave where the face appears.. here
Also, you can download Spectrogram here
Not sure of which program in *nix can do it.. any ideas?

That's only if you view it playing backwards.
There is also a nifty looking spiral at the end of Windowlicker. It can be seen with the NullSoft Tiny Fullscreen visual that comes with winamp. It even shows up in the mp3 version available on the net. Very cool!
So music from Aphex Twin is not just random noise anymore!
"The image doesn't appear in an MP3 file of the song; the compression algorithm destroys the image"
this is absolutely not true. ive watched it on my mp3 version, looks exactly the same.
another site regarding this was linked on memepool a few weeks ago.

I'd rather see a face with music hidden in it.
Could this be a new means of watermarking audio? The note about mp3 and other lossy compressions distorting/removing the image from the music makes me wonder if this couldn't be used as a form of DRM. It would require a special audio player to enforce it I suppose. Food for thought...or maybe just food.
now, this is a great reason to buy the actual CD. I'd pay $15 for that. Then again, I also LIKE Aphex Twins' music. On the other hand, it's not very useful if it's copy-protected and won't play on a PC. I think there's a lesson to be learned here for both the RIAA and the "cartel-protest" crowd.
These are my friends, See how they glisten. See this one shine, how he smiles in the light.
Back in the DOS days, I'd stare at the spectrograph in Cubic Player while playing all those neat Purple Motion tunes (I still play them, just in XMMS now)
I always wondered if it would be possible to do the opposite of a spectrograph.. take an image and convert it to a sound... I guess it is!
Woohoo! Another reason to get stoned and listen to Aphex Twin!!!!
My countryman not only paved new way in what is literally mulimaedia, but he has also demonstrated awe-inspiring restraint in letting this be discovered independently, after nearly three years.
Mr. Twin, I applaud you.

I found this about a year and a half ago, oddly enough at about 3 im the morning... scared the hell out of me but was the neatest find. I was watching songs in winamp with the voiceprint plugin that comes with it. Think it would make neat wallpaper.
I took a screenshot and sent it to my friends and we looked around the web but couldnt find anyone else who had come across this. I think the song was "Complex Mathematical Equation" but i cant remember...
its aphex twin, so you know its kickass
That's a good way for some random band to boost their sales: encode moving pictures of a scantily clad pop-star dancing (or in some other way gyrating) into their music. People would have to buy their CD, and as a bonus they get some music. And as a bigger bonus, they get pictures of Britney...
Lack of eloquence does not denote lack of intelligence, though they often coincide.
i think its great that people are experimenting with this kind of stuff... what about the music itself though? for centuries music has been around, but its only in the last couple of decades when video came out that image has influenced the music. now that we have pictures encoded into sound, where will we go next?
I am unique, just like you, and you, and you...
Isn't this just asking for another method of circumvention? That is, if it is to be used as some form of copy protection. Someone could encode the images as .mpg and the music as .mp3, and offer them both up for download, and the downloader could combine them at his end if he really wanted to have the image with the sound. Or just keep them separate. Shouldn't be too tough, right?

How "audible" is the image that appears on the Aphex Twin track? Can this be used for digital watermarking for other kinds of music, or would the image be too "loud"?
This plugin works for xmms. Get the dspectogram 1.2.tar.gz - It looks really freaky as the two faces (L and R) channels appear....
Doesn't Winamp run only on Windows? Surely there must be software for a free OS that does this.
The sad part is that true artists like AFX are pretty much ignored and panned by the lables and the radio stations while crap get's all the airplay.
Sorry, but AFX has always been much more a musician than the rest of the mot there on pop-radio. Just like Moby,NutralMilk hotel, and the rest of the "underground" they all have more talent in their toenails than every artist that get's big-station radio play.
And that my friends is exactly why I am proud of my wierd music collection. (I admit..it's wierd... AFX is wierd.. by popular standards...)

I can see it, it's the last few seconds of the second track on the CD. I'm using the SND editor under Linux to see it but the image looks slightly different from the one shown on the article's website. I have a U.S. CD so there may be more than one version of this song, depending on the country the CDs were pressed. On mine, he's not smiling a toothy grin, but instead his mouth is closed. Weird.

This is really old news. I remember seeing the image on the Windowlicker track about six months ago when rumours first started circulating about it on the internet. I'm kind of curious why people are raising a big fuss about it now...it was pretty widespread news among fans a long time ago.

Could it be Jesus' face????
aphex twin/RDJ is quite the geek, making his own synths and coding some of his own software for use in his music....it's one of the reasons it takes him ages to get a fucking album out, apparently. there was a recent interview where he said he'd lost an mp3 player that was loaded with tons of his songs (and i think squarepusher demos too -- aphex and pusher are friends,) like two albums' worth of unreleased material he was sorting through....just left the player on a plane and that his paranoia over getting the songs released on the 'net was one impetus for releasing his latest album, druqks. more proof that mp3s have changed artists' modus operandi, even if it's not all artists.
FreeBSD for the impatient.
Does this have applications for low bitrate video encoding?

There are two images, the first is of Mr. Twin's face at about 5:48 into the song, the second is a swirl at about 6:00. You pry only saw the swirl, reason being it has a lot of blackspace and its very easy to make out swirling kind of noise. The face however, sounds like just regular old garbled Apex Twin noise.
Winamp ran excellently in Wine when I tried it. Well enough that I used it instead of any MP3 Player I found that was made for Linux.

I re-rendered the image with higher resolution and inverted the colors, and the details showed up. It's the same image. My bad.
There are a lot of free spectrogram tools around, for two reasons:
They're useful for a number of sciences (linguistics, for instance uses them a crapload).
They're just FFTs which nearly everyone who studies computer science winds up implementing sometime or another during their education.

In Winamp 2.80 use the visualization plugin Nullsoft Tiny Fullscreen 2001 (v2.04) then selecting "Sexy Scrolling Voiceprint" it's a built-in plugin with Winamp 2.80.
Then about 5:30 into the 2nd track titled "symbol" on the Windowlicker EP Album there is the face. Earlier in the song there are other blocks that appear to be images as well, or at least were implanted using the MetaSynth program.

Yet if you study math you don't usually even hear about Fourier Transforms until grad school and then you just learn the theory behind them. You never actually calculate one. Way too many calculations with like actual numbers and stuff
Steganography is encoding something in another medium so as not to alter the carrier medium, like a watermark. What Aphex Twin did was to use a piece of software that converts graphics to sound (x, y, z = time, frequency, and intensity/volume) via an Inverse Fast-Fourier Transform. There is no encoding involved, the picture *is* the sound that you hear. Big difference.
When I was a kid, we only had one Darth.
Christian Music will have crosses, doves, and christian fish encoded into the signal, which will probably improve the music.
You could very well be right. Simple geometric figures, such as a cross made of band-passed noise, can be used as percussion, and a line drawing of a dove can easily be hidden in a bird call (heh).
but that, when translated to mp3, will crash your computer.
Not possible unless a buggy MP3 encoder passes such a file to a buggy MP3 decoder. Well-written codecs don't crash.
But you left one out: Cheesy electronic music will have the printed source code for a CSS decoder.

I've been waiting years for Aphex to get props in slashdot.. although anybody who's read the afx faq has known about this for a while.
Trolls, it must be cool to be that bored.
Technicaly the technique being employed is considered a form of non-robust watermarking, rather then steganography.
Steganographic techniques embed covert information in a an object or "stego-cover". Typicaly the information is highly encrypted and neither visualy or satisticly alters the image.
The technique described here falls more under the catagory of watermarking, principaly the application of tamper-detection. Tamper-detection watermarks such as this are designed to be as fragile as possible, such that any alteration destorys the watermark. This family of watermarks thus ensure that the content has not been altered since original distribution.

Concidering that they:
A) Didn't test it
B) Strongly implied that it was true and not that they got that information from the article
I would say that it is slashdot's fault for posting it as the truth. Not that it's the first time or that it matters one bit though. The face seems to be completly unaffected by mp3 compression (I saw it fine in my 192 kps version of the song).
A word on this song itself. The end of the song has a breakdown effect; an increase in dissanace at first which leads to "random" static. The last piece of static in the song is his face.
It looks more like Sally Struthers' tits to me...

I've been an aphex twin fan for a couple of years now.. and AFAIK the face you see is old news.. i first heared about it about a year ago...
The sound pictures were made by converting an image into a power spectrum, and then converting the power spectrum into a sound signal.
The code to make these pictures took a couple of hours to write. With more attention to detail, im sure that better results (both sounding and looking) are possible.. but this was just 'proof of concept, before hitting the bar'. :)

Well, I was being a little facetious. They were covered in Baby Rudin, but we skipped that chapter in order to have time at the end of the year to develop the Lebesgue integral.
On track one of the windowlicker EP, there's a spiral at the end. There's also an audioplot on his new Drukq's album.
He's also put data into his songs which can be extracted. On his "Richard D James" album, there's two tracks with ZX Spectrum tape headers at the beginning and ends of the tracks which can be read into some spectrum emulators.
Recently, he released a single called "Two remixes by AFX" featuring a remix of 808 states flowcoma. The last track titles "Bonus High Frequency Sounds" is basically a data track from some computer (not a spectrum), hopefully someone out there would recognise its sound and extract the information out of it, because I've tried and all I've got is junk data...
Task Mangler
I wrote a quick app that allows embedding of an image in a similar way, and have verified that neither encoding to mp3 nor encoding to ogg destroys the image. I don't know where Wired got the idea, but they're wrong.
If you think about it, it makes perfect sense too: changing the frequency components of the sound so radically that the image is no longer visible would mean that the music sounds totally different too. mp3 and ogg are lossy, but they're not THAT destructive.
That's funny. I only study engineering and I learned about them (and had to calculate them) in sophomore calculus.
Some points - as others have mentioned, mp3 encoding does not get rid of the face - it is still spooky.
And one of the standard visualisation effects on the empeg shows it beautifully.
What's even weirder is it doesn't sound too nasty, musically. Every time I've tried to draw pics in the waveform it's sounded harsh and metallic.
This spoof IRC session is very funny

As for preserving the image, I've found at least the RDJ-album face in all mp3 versions of this song, so that shouldn't be difficult.

It does exactly this, and it's excellent fun to play around with.
Yawn, this AFX face thing is old news. I heard about it months ago and it's been fairly common knowledge among AFX fans for awhile now. Oh, well.
However, I've been looking for other songs with odd spectrographs. The most recent contender has been the track "A is to B as B is to C" on geogaddi, the most recent Boards of Canada LP. Nothing as obvious as a face, but it has some strange effects, plus something apparently hidden in the high frequencies (at around 15000Hz, if I remember correctly). Anyone have any idea what this is? (You can view an image of the spectrograph here).

Ok, while this is cool, I think it's a bit blown out of proportion.

It's an amazing piece of software. I'd imagine more liekly than purposeuly putting the image in the song. He took the image in metasynth and got the sound from it and thought hey this sounds good Ill use it. Anyway that's just my opinion.
XMMS (X MultiMedia System) is the Winamp for Linux. It does pretty much everything that Winamp does (including support for skins, visulisation plugins etc) and it's Open Source. I always prefer running applications natively instead of emulating, providing that I'm given the choice. 'Nuff said.
It won't encode as well as mp3, but it wont wreck the image either.

I don't know exactly how long sonograms have been around but with them we take reflected sound information and build an image. Go to
http://www.seeingwithsound.com/eyebrows.htm
and see a more useful application of this technology.
In this case, Richard James took a Mac only program and "read" the image which generated output to simulate sonography. Take the noise file it outputs and mix into your song. Not a very difficult, time consuming, or new idea.
I suppose it's no wonder that this thread isn't very long as this is an old idea.

The Aphex track Vaz Deferenz from Donkey Rhubarb has images of sperm swimming along through the track. It's great because the sounds and images go together quite well, with the 'climax' of the track co-inciding with a swarm of sperm converging on an egg.
I imagine it would create a pseudo-animation effect if you used the Winamp voiceprint visualisaion.
At least that's how I remember it, I noticed it a few years ago when making a mix CD and I was editing the tracks in Cool Edit.
I seem to remember some penis shapes as well.... Well actually, they look more like arrows but they are pretty bloody Freudian.
