- WheresWallE, on 04/26/2008, -1/+223I'm pretty sure its called a Discrete Shepard scale, derived from Shepard tones. I did a Music Technology degree and we studied lots of audio illusions like this.

- SuperOmegaSlack, on 04/26/2008, -1/+85Yeah... it's the same tones. You can tell by just listening to the middle, sounds the same every time. Pretty cool effect though!
- inactive, on 04/26/2008, -10/+78Double WTF.
1) How is this possible?
2) What's up with that comment?!?! - dcd722, on 04/26/2008, -4/+67When you hear it you will ***** brix.
- slikk115, on 04/26/2008, -3/+60each note is played at different octaves simultaneously...
its just that your mind is listening to the one it wants to hear - grungegbunny, on 04/26/2008, -9/+62If you listen close that last Da Da (don't know what else to call it) it drops a bit lower so when you replay it , the first set of Da's sounds like its just a bit higher in pitch.

Nice, that rhymed. - strobelite33, on 04/26/2008, -3/+44dugg for mind blown.
- synystar, on 04/26/2008, -2/+421) Our brains are not perfect and our senses can be easily deceived.
2) He is obviously trying to create possibilities of understanding what actually causes the allergy. Or something. - Akaji, on 04/26/2008, -1/+33It seems like the video has a few different pitches of audio playing at a time, and your ears become accustomed to the higher-pitched noises as you listen to the scale go up. The next time you play it, you hear the audio that's higher more than the lower audio... but if you listen closely, you can still hear the lower audio.
- rabidjester, on 04/26/2008, -0/+30If you don't spell out your words on Digg, the terrorists win. Really, it's two extra characters, make the effort.
I'm not sure why this gets under my skin, I must be getting old. - commenter01, on 04/26/2008, -0/+28not really that complicated. it's called a shepard tone.
http://en.wikipedia.org/wiki/Shepard_tone - TheKingInYellow, on 04/26/2008, -4/+29blood erupts from my ears
- inactive, on 04/26/2008, -2/+25It's an optical illusion... for your ears!
- amanilaenvelope, on 04/26/2008, -1/+22i was half expecting one of the monsters from "killer klowns from outer space" to jump out at me.
- staticdrifter, on 04/26/2008, -0/+18There are also a couple layers being played. Each "Da" has some low notes and high notes...once you listen your mind starts to almost "imagine" them at a higher pitch than they are.
- Cenobite, on 04/26/2008, -0/+17Why on earth wouldn't they, though? It seems like a pretty legitimate field of study to me.
- BudgingMidget, on 04/26/2008, -4/+16The music from the endless stairs of Super mario 64 use the same audio illusion: http://www.youtube.com/watch?v=ZSWbWsyV0-A
- JefffN, on 04/26/2008, -0/+11Here's a visual explanation of what is going on:
http://www.netalive.org/tinkering/shepard-effect/ - insomniacal, on 04/26/2008, -4/+15Here's a bloke playing the Super Mario 64 infinite stairs song on the piano -- you can see how it's done (two hands playing same scale in different octaves).
http://www.youtube.com/watch?v=RYlglVwpMlg&NR=1 - blahtastic, on 04/26/2008, -0/+11Sounds like a sound technician/sound engineering degree? I don't see whats wrong with that being at a college.
- xedd, on 04/26/2008, -0/+9We hear what you did there.
- Brian48216, on 04/26/2008, -0/+8shocked that I didn't get rickrolled.
- K3ITHK, on 04/26/2008, -1/+9Most useful comment ever. Someone get this man a prize.
- tillerman00, on 04/27/2008, -0/+8Weird... not only does the tune seem to alter its tone and pitch upon subsequent listenings, but I found myself exponentially giving less a ***** with each repetition. Odd indeed.
- inactive, on 04/26/2008, -4/+11***** you asshat
- Spetz, on 04/26/2008, -0/+7People with good musical ears will notice that it doesn't, right away.
- DannySpace, on 04/26/2008, -1/+8Fool, your Jedi Mind-Tricks are useless on me.
- inactive, on 04/26/2008, -0/+7It's got a lot to do ( but it's not the full story, there's the octave thing as well ) with the fact that's it's rising over a six bar loop and we're used to resolving things in fours musically. Therefore: the first two bars when replaying the loop become what should be the last two bars of the previous eight bar loop giving the illusion of a constant rising tone.
Sample it, put in back into a sequencer, then find it's tempo with the metronome and you'll see what I mean. - LimeParrot, on 04/26/2008, -0/+6Yeah it's the same tones. Another way to tell is, when finished, wait like 30 seconds to press play again. After the waiting time you can tell it's the same tone (but like you said, it's pretty cool how replaying consecutively makes it sound like it's climbing and climbing).
- Topslakr, on 04/26/2008, -1/+7You are hearing two notes, a low and a high. The scale that come up from the low note ends one note before the scale for the high part starts. When you listen to it over and over your brain continues thinking the low scale that leads into the high one but by the end of the loop your brain as 'reset' or reacclimatized to the tones so that when you play it again.. that low note transitions back into the high one and the scale continues. You could replicate this on a piano or anything that can play two notes at once.
- frozenjakalope, on 04/26/2008, -0/+6It is. I'm doing one now, with aims to becoming a studio engineer.
- synystar, on 04/26/2008, -0/+6Repeat the first 10 seconds a few times. Then listen to the whole thing a couple of times. Repeat as needed to understand the the auditory illusion.
- shondell, on 04/26/2008, -4/+9audible illusion
- boydrew, on 04/26/2008, -2/+7aural illusion
- xedd, on 04/26/2008, -3/+8Tell them to shut their ***** traps and vote Democrat, the dumb pricks.
- senkmajer, on 04/26/2008, -0/+5Josh is right. I does, but with this caveat: it's just not as subtle so not as effective.
- inactive, on 04/26/2008, -2/+7DOOOOOOOUUUUUUUUUUCHEEBAAAAAAAAAAAAAAAAAAAAAAG
- tdmand, on 04/26/2008, -0/+4The sound example on the linked Wikipedia page from WheresWallE's comment is also pretty awesome.
- inactive, on 04/26/2008, -1/+5You can't edit comments with URLs. You'll lose them
When is the new comment system supposed to launch? - nocturnoculto, on 04/26/2008, -0/+4yeah... if you listen to music... you see there are these people who record it. it helps if they know what they are doing.
- Neovos, on 04/26/2008, -0/+4Now for those who speak music, heres exactly whats going on:
-It's middle C and a C an octave below. It's going up the chromatic scale all the way to B and stops.
-If you consider the ending on a B to be the last "key," then it actually is transposing up a half step when you play it again but it's really just completing the octave. That is why it seems to change tonality every time. Thats one part of the illusion.
-The other part of it is that while there are just 2 notes being played spanning one complete octave, the there are many additional octaves present in the sound as well through the overtone series. That is the reason it may sound like it keeps starting from a higher octave every time it starts. The scale movement is guiding your ear to the next octave overtone. - TomRemixed, on 04/26/2008, -0/+4This is kinda related...
http://gprime.net/flash.php/soundimmersion - consoneo, on 04/26/2008, -0/+3Yup yup, I was going through it second by second starting it over. Up to eleven seconds you don't get the effect, but if you play it all the way through (12 sec), you get the effect.
- BruceBogtrotter, on 04/27/2008, -0/+3more fun*
- inactive, on 04/26/2008, -0/+3Mirror here
http://www.youtube.com/watch?v=6QRgo_vHcpA - inactive, on 04/26/2008, -2/+5This on YouTube anywhere? 5min has gone *****-up.
- lacreme, on 04/26/2008, -0/+3it's not getting higher, you are.
- xxMarka, on 04/26/2008, -0/+3no way, I thought it was magic
