Awesome!

[mulchdiggums888]

WTF my ear just got owned

[nebby1956]

great!

[TheMeikamanne]

omg! worked

[AyuTutorielz]

Free repeat button : 0:00

[robmoto117]

I've figured this out.

If you listen carefully, the same note is being played twice. For instance a High e and a Low e. They play these keys but then move on the next key but at a lower octave. This way you still hear the original bass note and your mind is tricked into thinking that the new bass note is the original. It does this until it reaches 1 note before it's starting point at which point you replay it and the cycle repeats.

[rachelishot0]

@robmoto117 Clever huh ..

[Scullnblades]

I may be the only one to noticed when the pitch replays again. It sorta sounds neverending but if you focus you can hear when it replays itself.

It repeats every 4 seconds, the first repeat is at 0:04

[Toetallix]

clever stuff, two pitches of sound you see, if you listen to the 'high end' part of the sound, the 1st note is a high octive, then it drops octave for the rest of it, while the 'lower end' part of it ascends. Compare how much lower the 'low end' is at the begenning to the end.

[HayaMatea]

It gets higher pitched every time you play, if you play it right after the last play.

[Jacbo96]

OMG

[PrimeNuggetz]

WTFWTFWTF THIS DOESNT MAKE SENSE. Im tooo fuckin high for this shit,

[1234567899413]

Omg,That's so impossible

[jessnjax1]

lol its amazing! Um.. is it normal that I heard it even after I stopped replaying it?? lmao! I only replayed it 3 times.

[oOTurquioseZebraOo]

Omg that's weird lol!!!

[invader924]

far thats wearid

[gabo1405]

[vercygentix]

didnt work for me, but maybe its because im the terminater and i must kill john conner

[smileyHsP]

@vercygentix aren't you supposed to protect him ?

[me97kid]

ahaaa, wow. thats cool!

[FuckNewbs]

haha kewl

[lorenrose]

I must be deaf. I hear the same thing each time

[yaboijunior]

listen to the first and last tune .. the first ones high and the last one is low.. they start high and end low buy using the same key

[UniQueMaSterPiecE1]

it starts off at the end of the octave, and then drops down an octave (during the chromatic run) and finishes 1/2 step before the beginning.

[Temarisboy]

I'm a music major so I only heard the one octave :\

[Joelby81]

@Temarisboy Oh wow, are you really a music major?.... you must be awesome.. No you really are awesome. Im an electrician and a musician and I rekon your a dickhead

[Temarisboy]

@Joelby81 Hur hur, I assume you have are a horrible electrician and have no job so you just troll around youtube all day and comment on shit. I also "rekon" as you put it that you spelled "you're" wrong. Your (as in possessive) a dickhead is saying "You own a dick head." Which I do thanks :D . What you probably meant (although I have no idea what your hick brain meant) was You're as in You are.

[Obangg]

@Temarisboy k honestly both of you are fuck ups. but you especially, you just avoided everything he said and picked at his grammar. shut the fuck up.

[banga999]

holy shit

for those who cant understand, the first time you play the video the pitch increases, right? when you replay it seems to have a higher pitch than the last note.

[94reset]

i thought a sacry peron was gonna pop up in the end O_o

[isingstuff123]

WOW!



[GZlegal]

it didnt work for u, coz ur not high, smoke that joint in front of u, then listen, live the real world bitches!

[guitarsoloperfection]

@GZlegal HAHA BAKED RIGHT NOW (Y)

[sutasman]

For all, in case you're wondering how he does it:

What makes it sound like it keeps rising is that in the simplest case, multiple overtones/octaves are layered on top of each other, all rising and spaced an octave apart. However the trick is not in pitch, but in volume. The notes with the lowest and highest frequencies are played the quietest and the middle frequency notes are played the loudest. The volume distribution over a single rising set of octaves is generally a gaussian distribution.

[13kz01]

awesome!

[sleemz1985]

i work with multi-tones, it just make the brain heard a sound, and the next time, he heard it diferently, i dunno the english word for "habituer"(in french).

but the brain just work to make you heard a sound, or not, like when you live in a city, klaxons and others sounds aren't really hard, but if you live in campaign, and go to the city, klaxon and other sounds like that are just terrifics, brain change your listen habitily ;)

[solispauwels]

I don't understand, I don't hear nothing

[thynameismrbob]

@solispauwels you have to keep replaying it (:

[sakuraXdropsX15]

it didn't work for me and i used headphones. i guess i'm not listing 2 it right

[ChristianCrisciullo]

Illusioni audio :D

fatela partire più volte e capirete :D

[mariosbellas]

nice

[mikeygough1]

wow fucking hell it works!

[silentlip1]

@mikeygough1

[silentlip1]

@mikeygough1 

[theproof7]

amazing!

[lckblade]

they used a lower pitch in the start rise till the mid and lows down by abit till the and ^^, but its very hard to know ^^

[Atroll995]

i get it, it continuse to go up every time u reply this

[PinkTutoo]

woooow how does that work ?

[Islandaholic]

I wonder how your brain does this.

[rob11rod]

nice!!

playing with octaves

[tiffanytsteve]

How does it work? :-)

[familyguy7121]

holy moly

[Jasonrox95]

Dude! haha

[roses00000]

waaw...lol

[acecepeda]

HOLY SHIT!

[Tuningcarman]

Cool

[BoricuaGurL143]

cool at first i thought it was one of those videos where the exorcist pops out and screams i literally yanked my headphones cuz i thought it was going to pop up lol

[kenora33]

hahaha me too, and all the comments I read were HOLY SHIT so yeah, one would think it was one of those stupid videos hahaha

[KitsuneShapeShifter]

@BoricuaGurL143 Same here!

[theo7491]

its like the escher picture were the stairs keep going up forever, except with sound

[wolfy5k]

LOL loadsa ppl thinking they're right. Its 3 octaves..... thats it. you hear the lowest the first time, then the middle one, then the highest. Listen for a 4th time, it goes back to the lowest....

[startacklebox]

its like a bunch of tones put together your brain wants it to keep climbing

[selurxelpirt]

It's a SHEPARD'S TONE, people.

[Grantalonus]

Very cool!

[chealsea68]

fake

[DjMrHuOfficial]

what fake you idiot?

[synzor]

WHAT THE FUCK HOW IS THIS POSSIBLE

[xsidxsalmonx]

HOLY CRAP

[Jeffnumber1fan09]

oh yh

[ytuber28341]

I don't hear it creeping up. I do hear the way the notes apear to creep up the first time you play it, then near the end, the tone is blended with a lower tone, same octave so that when you start the vid, it "matches" that tone so it appears to creep up.

The notes just do not seem to get higher & higher to my brain. I guess this doesn't work for me.

Maybe my hearing is too perfect for this to work, I don't know...

[astrayl]

the other possibility is your tone deaf. But yeah anyone who takes music theory and was forced to learn notes and steps by ear won't be confused.

[ytuber28341]

If I were tone deaf, I could not hear the changes.

What you are referring to are people who are tone deaf that cannot hear the changes, so it appears to "trick" them into thinking it is creeping up.

I can actually hear where they splice it back together with the same notes & start over!

[BabysxInxBlack]

omgf thats crazy!

[CrayonPhysiks]

every tone there is a chord (sorry for my bad english) and first you hear the lower note more but the next time you here the higher note more because your brain "knows" ( i dont know how to say) that in this series the notes go higher and higher

bad english i know!

[cambot7]

dont worry about it, on the internet if you can spell correctly you are already in the top 10% of english speakers.

[yy502tube]

i just made a ring tone with this x_x

[asw8680]

LOL

[drummerfreak72]

its a series of octaves

[ErrorlnDisplay]

o_0

[kamerontre]

wtf!? that freeked me out!

[Artorpion]

[picekkk]

WTF? weird feeling:P

[lpapa2]

[metallicaboy27]

Yeah it is and no need to get all pissed.

[Spiritstaker]

What The Fuk? haha cool..

[gerri]

omg. so cool.hahha

[xcliber]

holy fuck?!

[vickeey]

wow! :O

[dinkthegod]

the sound file is playing more than one frequency at one time but your brain doesn't pick up on this until it is expecting the next frequency.

[JakeAnti]

frequencies DUH

[aronbogdan]

wth ?

[Pyritie]

It's playing chords, that's why c:

[Allions10]

OGM HOW HOW!???!?!?!?!? LOL

[SambaDisaWinner]

it gets to a point where you start to hear no difference

[dalton0419]

it works like three times for me and then starts over

[Skrik111]

Nice!

[oloch004]

fuck!!!

[mangagor]

FREAKS ME OUT!!!!!

[oculthan]

que bosta!!

[binhoservice]

êita

[RussianScorpionLady]

aaaaaaah it freaks me out !!! >: C

[HUNsplat]

intresting.

[berpeti]

bullshit

[shrekazogree]

ugyanugy szol csak ami az elsö után ujra indul az magasabbnak tünik

[gergobazmeg]

It's just because the last 2 tunes are Bb - B, and the first two tunes are B - C, and the sound of the tunes contains lots of overtones, so you can't distinguish which octave you hear.

(I'm not sure about my english)

[avatarzenekar]

Exactly, you are spot on. Each tone contains either two tones (plus overtones) two octaves apart, or three tones an octave apart each (can't hear it clearly enough). Seems like your ear "tunes into" the octave you expect to hear, resulting in the illusion of hearing higher notes. After a while (perhaps the fourth or fifth time) my ear / brain started to "hear through" the illusion and therefore it stopped working.

[avatarzenekar]

(sorry I meant this as a reply to gergobazdmeg, plus there wasn't enough room for the full comment)

But this could have also been due to the fact that we ran out of notes to hear (eg if you heard the first octave first time, second octave second time and third one third time, since there isn't a fourth one, the illusion couldn't continue).

[avatarzenekar]

Pretty cool though. Another fine example of how the brain applies "processing" to the sounds you hear (as well as what you see, etc).

[Aragond68]

@gergobazmeg Excellent explanation. And yes, suitably freaky at first... and then not when yor read gergobazmeg explain it away. ;)

[xchemicalxsuicidex]

that's really weird

[FanslinksxD]

It goes high and down x__x

[KHFinalSora]

after like 3 times it stops...

[CantStopClickin]

Whoa.

[elvo84]

LOL

[wils500]

wierd but obvious

[peterfaj]

at the beginning you think it's still pitching up, but in the end you realize it's not really any higher than before.

[blazun]

I dont get it

[Askthisguy]

replay it then

[tylerwaite44455]

thats so cool
