In the Octave Illusion, when the chair was spinning, I saw it spinning to the left. Add shading to make it look like it's turning to the left, nothing changes. However, with the shading supposedly making it rotate right, it stayed rotating left, but it was like a computer model of a chair and the textures were on the wrong sides, causing me to see the opposite side of each part, but on the inside. I know that description was bad, so lemme try again. Imagine a hill. You see the front, and because it is in the shape of a circle, it juts out at you. Now imagine you are looking from the same side, but most of it was cut out, so that it now looks to be bending in, which the difference between the two can be described as convex and concave respectively. The same is applying to the chair, but with each part, like the seat, the legs, and the frame and bars of the back, all the while it is still spinning to the left.
That's great; in a way, being able to perceive the 3D geometry against the shading clues is sort of the ultimate illusion. That transitional moment while your brain scrambles and tries to re-parse the image is really interesting. I've had that for a half second or so watching the switching, but it doesn't hold. Reminds me of when you look at a stereoscopic image but you've crossed your eyes instead of un-crossing them, or vice versa. Maybe I should make a chair video where it switches back and forth a couple times a second.
I think its amazing that even when there is an effect that affects "most" people, there are still some who don't experience it (myself included with a few). We all see the range of biodiversity on the planet, and the range of cultural diversity, but its good to know that even amongst similar members of our spicies there is diversity in perception - we need that to spur innovation. It's awesome!
Like with illusionary continuity/discontinuity. I heard breaks in both tones, but it was a bit tougher with the second tone to understand that it was actually breaking.
Every person on earth hears things differently than any other. As a bass player, I hear chords and tonics. Other folks hear lyrics first. I have to strain to hear lyrics and even then half of it I can't understand..because my head is fully occupied with the music. When singing and playing my bass, I cannot conjure up any lyrics..I have to have them in front of me.
For me the chair illusion at 2:08 didn't change direction at all, in both views it was still rotating counter-clockwise (leftwards). What changed was the angle I was seeing the chair from, from above or from below. If anyone sees it rotating clockwise... I say: absolute lies!
The f***ing thing just kept rotating counterclockwise... I didn't see a damn thing to even insinuate the slightest difference... Maybe I can convince my brain otherwise in a later viewing... BUT this time... nope... counterclockwise the WHOLE time... never changed... didn't matter what the hell he said or how he changed the visuals... nothing... ;o)
I wasn’t tricked by either one of them either, but there could be an explanation for this. Maybe we were the type that didn’t perceive a break in the first audio, but perceived a break in the second audio because we were expecting it. Think about it. First audio has no break, so you assume the second one probably will have a break in it for a comparison. It might be because we were already expecting it, even subconsciously. Maybe if these audios were played with more time between them and no explanation beforehand, we wouldn’t go into them with any expectations and we might’ve been tricked by the second audio
@@junkyardwillie8320 solid theory. Something similar happened with the one with the sentence and the random noises in between which así had breaks. The first time I heard it I filled in the breaks in the voice but after having the knowledge that the voice did have breaks, I went back and actually heard the breaks that time around. I think having an explanation beforehand or going through the experience once makes your brain adapt.
The illusory continuity one is pretty interesting, It's pretty common practice in chiptune music due to the limited amount of channels you have to work with. Never really thought that there would be people that hear it differently.
There was a major problem in the demonstration; the second example had this 'clipping effect' which added to the interruption. I wonder what it would sound like if the tone was perfectly cut off by white noise and vice versa.
If you cannot hear the "cocktail party effect," you may have what is called "hidden hearing loss." It usually presents as loss of speech discrimination amongst noise, but you can hear perfectly fine in a quiet room or on a hearing test. Some studies have shown this to be more common in people who work in generally loud environments or repeatedly listen to loud music. It's a pretty hard thing to test for, and as far as I know, there is no specific "test" for it as of yet.
I've heard of that... and I think I might have a little as well. My hearing tests great, but as I've aged I notice that it's much harder to understand someone talking at a loud party. Or maybe I'm just too sensitive. :-)

I realise I have been spamming the comments sections of these videos, so I'll shut up now, but two things. 1) Most of these "illusions" I cannot hear, I hear what's actually happening, and 2) I realise thanks to you that I have been making use of several of these techniques for years in my music. I hear what's actually happening, but I wonder now that my listeners have been confused! It may explain why my bandcamp sales are in the ones rather than the thousands! Great series.
the cocktail party effect is what it feels like to have auditory processing disorder you over process sounds and are able to pick out what ever sound you want through headphones though it feels so much different to actual people talking you struggle to hear anything individually because it is a mess of signals coming through each ear in real life you take into account how the sounds travel through your skull and bones and you are usually able to tell where the person in the room is and pick out their voice because of this.
As someone with ASD, the Cocktail Party Effect is elusive -- we tend to hear ALL conversations and our brain gets fatigued trying to follow all of the conversations at once. I've left parties silently due to this -- I can't tolerate bars for the same reason.
Same, I actually realized recently that loud, repetitive music without vocals can make it easier to have conversations in big groups because the music masks all conversations except for the person right next to me
I know only one person who is genuinely, 100%, tone deaf. He has no concept of things being out of tune, and funnily enough he prefers house music which I think is connected.
Well, then he's most certainly not beat deaf. On another note (pun intended), I kind of lose track of notes if they're too deep, then it starts to sound all the same and bad either way. My father is musically gifted and can hear these subtle differences much better.
Same here, I've got adhd tho. I have huge problems understanding people with other noises going on. And being in a crowd is just game over for any communication attempt with me.
Yep, same here... as soon as the other voices came in I couldn't understand a thing she was saying. I could hear her, but I couldn't pick out any words.
This is known as hidden hearing loss. It usually presents as loss of speech discrimination amongst noise, but you can hear perfectly fine in a quiet room or on a hearing test.
@@Niscimble as far as i know (ive got ADD) it has something to do with being able to focus on the sounds you need to hear, since concentration is an issue this causes the inability to distinguish the sounds,
The Illusory continuity phenomenon is used all the time in dance music. Since the bass and kick usually occupy the same sonic space, it's common that the bass line is ducked for 50-150ms whenever the kick drum hits. This ensures that the beat never gets "lost" in the mix. Unless you're listening for it, you don't ever perceive the bass as disappearing.
Totally... and i'm not an aficionado of the genre, but it seems like illusory continuity comes a lot in the glitchy stuttering types of passages where things cut in and out, are interspliced with other sounds, etc.
I'm definitely not tone deaf, but I'm pretty sure that I'm lyric-deaf. The amount of songs I hear and just can't seem to understand what they are saying is mind boggling to me. Either I listen to too much classical music so my brain is just out of practice of understanding "sung" words, or pop songs do a really terrible job of making the vocals clear in the final mixing and mastering.
Agreed. I made a simple keyboard song when I was in high school, where I panned an ascending scale in the left channel and descending scale in the right channel. It was totally boring on each ear. But when I listed to L and R at the same time, ping-ponging back n forth, it made this completely different, funky tempo illusion. Now I at least have a name for it -- Cambiata -- but I still don't know why it's making the funky tempo.
In "The Cocktail Party" illusion I lost the voice of the "Sunset" speaker as soon as it began to fade against the other voices. I have always found crowded conversation impossible to comprehend. I never knew there was a name for this phenomenon. That's why I always prefer gatherings of no more than half a dozen friends. Thank you for enlightening me.
Well then... 9:52 Literally a perfect summed up example of my social anxiety as I can indistinctly hear each conversation at the exact same time and am unable to focus on just one. Stimulation overwhelms and panic induced. Even after was pointed out and tried to focus on just the one lady. No dice. fun.
10:46 as a music producer I always face this problem, when I make 2 steps hats pattern then adding a snare I remove the hat when the snare starts playing it's like a side chaining effect
i liked the cocktail party one because in high school i noticed that i used to be able to almost isolate one person's voice if I knew what it sounded like while i was in the cafeteria and everyone was talking and if i was able to see them clearly. sometimes from pretty far across the room too
With that octive ellusion in stereo, not only did i heard both high & the low tone but that high tone seemed to be in another pitch as well, but once you played then saperately, i could clearly hear That both both the high & low tone were at the same pitch, i was mind blown away by this ellusion , also that test at the end were a tone got interrupted, i was still believing in that they were both continues, woow , how our ears and/or braincould decieve.
I naturally wrote with my left hand as a child, but was forced by my kindergarten teacher to use my right hand... Glad they don't do that anymore. The bright side is I'm fairly ambidextrous now, but prefer to write with my left hand, draw/paint with both, and do everything else with my right. Point being, I did tend to hear the things lefties tended to hear. Makes me ponder... everything. 🧐 Excited to watch this with my right handed SO, and find out how he perceives each one! Great series.
I actually found an Illusionary continuity effect in real life, last year, I went on a trip to Europe, one of the places I went to was Italy, and occasionally you’re going to hear an emergency vehicle drive past with the warning signals on, in case anyone has never heard it before it’s basically a steady tone, that occasionally jumps up to a higher one before quickly moving back down to the original pitch, it does this cycle twice quickly then holds on the lower tone, then it repeats, the lower tone stops for the duration of the higher one, and when one was close to us, like if it was on the road right next to us, I would hear it properly, but I noticed that if I were further away, the lower tone would sound continuous, as in it would sound like the higher tone was just going on top of it, and the lower tone had no gaps, in fact, it took me a while to realize that it wasn’t continuous
I have just watched the video [ as well as the previous parts ] and realized that it came out exaclly 1 year ago! Happy anniversary !!! All 3 videos were so much fun! I am very thankful for that Hope you are doing great Mister Connor^^ [ or Miss- or Mx- Please say if I have used the wrong pronounce]
Nonlinear pitch perception is a big reason why chords tend to be used in the higher registers, while the basslines are often a single note or octave. the differences can more easily be heard in higer tones than in lower ones, where it just turns to mush instead. (I'd love to link to where I learned about this, cite my sources, share some knowledge, all that jazz; but I can't figure out who I found out about it from. Sorry.) Also the cambiata illusion was tons of fun!
The Octave Illusion was really weird to me. When it played the first time, I didn't hear a left/right switch, but rather two cimpletely different tones being played in the centre, like if you turned back and forth between two similar instruments on your synth. I am listening on fully functional headphones, so I do have stereo sound, but... yeah, that was weird.
The issue with the "illusory discontinuity" example is that, after the discontinuity, the tone continues as though it had only just been briefly paused rather than briefly muted. I'd be curious to see if it would fool me if it was done the other way, because I could hear the discontinuities clearly.
Interesting; the audio is actually briefly muted, not paused, as you say. I wonder if the fact that it sounds otherwise to you it yet another illusion of some kind. :-)
I think that glissando effect correlates to the fill in blanks effect as you described in previous video. The steady pitched note is overriding the second one and our brain fills in the blank so the sound sometimes appear to be more in the center as our brains smooth it out.
My dad was completely tone deaf. I could play the same note twice, or 2 different notes, even a few octaves apart. Every time he would say it was the same note.
For the octave illusion I at first heard a higher and lower pitch flipping back and forth between left and right. Even after the entire illusion was explained I could hear the higher pitch staying on one side. It was mentioned that it's more complicated for left handed people and I wonder if that has anything to do with it
I would argue perceiving the broken tone as continuous is actually correct because assuming you were playing white noise, all the needed frequencies were there ;)
this episode was the most fun for my A.D.D. Much different for me. I don't discern an individual voice in crowd but lock onto all. It's quite annoying at restaurants. I often leave places that don't have any sound dampening.
So whenever your dominant hand is meant to dictate where you'll hear a sound, I either hear it in both ears, or the middle. I think this might be because I'm omnidexterous(I use my right hand for writing, but both hands equally and indiscriminately with every other task), but there might be some other factors in play as well. It might just be me being weird as well.
Octave illusion: hmm I could clearly hear what was going on at the beginning. I couldn't even get myself to imagine either of the biased illusions. Glissando illusion: That didn't work for me, either. I do have studio monitors with a good stereo image though. Cambiata Illusion: Same. I could just hear all the notes where they were actually played. Deutsche Scale: ooh that worked. This series is fascinating!
Thank you so much! I've always been interested in sound effects and everything related to sound, I'm totally blind and have perfect pitch and... and I still was tricked by the Deutsch scale illusion! :)
This is where I was lured into your channel. I shall not listen to it again! OK, maybe, when I play it for my wife. I might first have to test listening to this with the surround sound in our living room; I doubt I could get her to wear headphones or not the kind I would have available in the living room. As you may be able to surmise from this. No, she will not come into my office and use my excellent headset there. She always reacts as if I am a spider luring her into my web. 😕 "Oh, meh!" she said, listening through the surround sound in the living room. (He hypothesized from experience!) Shhh! She hates it when she knows I have hearing problems with tinnitus, and I show her how bad her ears are! ;-)
“illusory continuity/discontinuity” - any perceived continuity is an illusion, the wave shape MUST change to produce the short noise if they are generated by the same source.
Thats what I was thinking.. especially since the interruption was basically white noise, picking out the existence or nonexistence of the constant tone seems irrelevant to me.
The octave illusion was strange for me. I'm right-handed but by default I heard the higher pitch on the left, and I didn't manage to switch right until the flashing note symbols hinted that way (though after that I could switch without them). Then when it was slowed down, and you could clearly distinguish what was happening in each ear, it still felt left-leaning. The two ears' channels were readily distinguishable, but within each ear's "sound-stage", the higher tone sounded a bit further left in both ears. It felt like roughly a 30° angle off vertical. Which itself is a strange thing to say since it conflates "high" and "low" pitch with vertical spatial position.
Interestingly, after my fall/TBI/stroke and the initial deafness, I found that I have what I would call Cocktail Party Syndrome -- I simply cannot differentiate readily between two voices simultaneously commanding my attention. Whereas, of course, with the Cocktail Party Effect, people can usually differentiate and shift their mental focus readily between two (or several) separate voices.
The illusory dis/continuity was odd for me, because I could correctly tell for both cases when the tone was broken vs not... wonder what that says about my neurons LOL
This sounds like what goes on during my hearing tests. I can just hear a slight difference in the tone/pitch, but my ears/brain precieve it as two different sounds.
For the Octave Illusion, I couldn't hear a high/low bias in either ear; I heard both in both ears. I'm right-handed. And I don't have sound enhancements on. And I'm using stereo audio in Skullcandy Crusher headphones.
I really needed to focus on the chair illusion when he made it to the opposite direction, at first i just thought i was looking trough the chair and seeing the legs, but still rotating the same way as before. Like it was a ghost chair
Now I know why parties are acoustic overkill for me, my brain just cannot single out one voice to listen to. its just garble garble xD Thanks for these videos, they're super interesting!
A bit of deja vu here. I think Steve Drews used cambiata in his "Waterwheel" composition on Mother Mallard's first LP. Also, I think Klaus Schulze used deutsch scales in the into to his piece "Crystal Lake" from Mirage.
It is truly mind-blowing how Tchaikovsky's genius utilizes psychoacoustics to make violins sound like a piano!
lmaoo
I'm a huge fan of that particular symphony and it was shocking to me to see that effect.
which work?
Always figured Tchaikovsky for a genius at some level... now it's confirmed. ;o)
Ahaha, Love it!

With that octive ellusion in stereo, not only did i heard both high & the low tone but that high tone seemed to be in another pitch as well, but once you played then saperately, i could clearly hear That both both the high & low tone were at the same pitch, i was mind blown away by this ellusion , also that test at the end were a tone got interrupted, i was still believing in that they were both continues, woow , how our ears and/or braincould decieve.
Really enjoying this series. started late in understanding music and these are a big help
10:18 "But did you hear the moonwalking bear?"
Me: being interrogated by a teacher
my classmates: 10:29
From a music-producers view, this was just mindblowing.. instant sub. Thanks!
I actually heard a perfect fifth in the octave illusion
Yes the organ sound he used has strongly this 3rd harmonic.
Wow, these videos are so underrated
Keep up the amazing work! Incredible
I naturally wrote with my left hand as a child, but was forced by my kindergarten teacher to use my right hand... Glad they don't do that anymore. The bright side is I'm fairly ambidextrous now, but prefer to write with my left hand, draw/paint with both, and do everything else with my right. Point being, I did tend to hear the things lefties tended to hear. Makes me ponder... everything. 🧐
Excited to watch this with my right handed SO, and find out how he perceives each one! Great series.
I actually found an Illusionary continuity effect in real life, last year, I went on a trip to Europe, one of the places I went to was Italy, and occasionally you’re going to hear an emergency vehicle drive past with the warning signals on, in case anyone has never heard it before it’s basically a steady tone, that occasionally jumps up to a higher one before quickly moving back down to the original pitch, it does this cycle twice quickly then holds on the lower tone, then it repeats, the lower tone stops for the duration of the higher one, and when one was close to us, like if it was on the road right next to us, I would hear it properly, but I noticed that if I were further away, the lower tone would sound continuous, as in it would sound like the higher tone was just going on top of it, and the lower tone had no gaps, in fact, it took me a while to realize that it wasn’t continuous
Hah, yeah, an in-the-wild instance of the effect, nice. :-)
I have just watched the video [ as well as the previous parts ] and realized that it came out exaclly 1 year ago! Happy anniversary !!! All 3 videos were so much fun! I am very thankful for that
Hope you are doing great Mister Connor^^ [ or Miss- or Mx- Please say if I have used the wrong pronounce]
A lot of these are just cutting up cohesive musical phrases, panning elements left and right then being amazed that the phrase remains consistent.
brilliant series! thank you!
I'm loving your videos so much!!! More please!!!
Nonlinear pitch perception is a big reason why chords tend to be used in the higher registers, while the basslines are often a single note or octave. the differences can more easily be heard in higer tones than in lower ones, where it just turns to mush instead. (I'd love to link to where I learned about this, cite my sources, share some knowledge, all that jazz; but I can't figure out who I found out about it from. Sorry.)
Also the cambiata illusion was tons of fun!
The Octave Illusion was really weird to me.
When it played the first time, I didn't hear a left/right switch, but rather two cimpletely different tones being played in the centre, like if you turned back and forth between two similar instruments on your synth.
I am listening on fully functional headphones, so I do have stereo sound, but... yeah, that was weird.
Love this stuff. Facinating peek into the minds perception. Leads me to contemplate its applications.
I’m right handed for nearly everything… but I think I’m left eared.
The issue with the "illusory discontinuity" example is that, after the discontinuity, the tone continues as though it had only just been briefly paused rather than briefly muted. I'd be curious to see if it would fool me if it was done the other way, because I could hear the discontinuities clearly.
Interesting; the audio is actually briefly muted, not paused, as you say. I wonder if the fact that it sounds otherwise to you it yet another illusion of some kind. :-)
@@CaseyConnor Huh! Neat!
I think that glissando effect correlates to the fill in blanks effect as you described in previous video. The steady pitched note is overriding the second one and our brain fills in the blank so the sound sometimes appear to be more in the center as our brains smooth it out.
2:29
my mind broke trying to process the chair as spinning left. i actually struggled to properly understand what was happening
My dad was completely tone deaf. I could play the same note twice, or 2 different notes, even a few octaves apart. Every time he would say it was the same note.
The cocktail party effect is a good way to explain my auditory processing disorder
I am right handed and I heard the lower sound on the right.
the glissando elusion i hear exactly what needed. the glissandoing tone is moving also fastly on the left right left right
For the octave illusion I at first heard a higher and lower pitch flipping back and forth between left and right. Even after the entire illusion was explained I could hear the higher pitch staying on one side. It was mentioned that it's more complicated for left handed people and I wonder if that has anything to do with it
I would argue perceiving the broken tone as continuous is actually correct because assuming you were playing white noise, all the needed frequencies were there ;)
...Wait is it called white noise because it's like how the color white is actually all of the colors together?
@@Zichqec He confused me too
1:50 I kinda did that in a song, I put an upwards arpeggio on the left channel and a downwards arpeggio on the right and the effect is pretty cool
this episode was the most fun for my A.D.D. Much different for me. I don't discern an individual voice in crowd but lock onto all. It's quite annoying at restaurants. I often leave places that don't have any sound dampening.
I can relate to that. Especially as I get older it has become harder to enjoy being in loud places for this reason.
So whenever your dominant hand is meant to dictate where you'll hear a sound, I either hear it in both ears, or the middle. I think this might be because I'm omnidexterous(I use my right hand for writing, but both hands equally and indiscriminately with every other task), but there might be some other factors in play as well. It might just be me being weird as well.
The Glissando illusion actually worked for me in headphones
Octave illusion: hmm I could clearly hear what was going on at the beginning. I couldn't even get myself to imagine either of the biased illusions.
Glissando illusion: That didn't work for me, either. I do have studio monitors with a good stereo image though.
Cambiata Illusion: Same. I could just hear all the notes where they were actually played.
Deutsche Scale: ooh that worked.
This series is fascinating!
As someone who is fully deaf in one ear, I’m disappointed that I can’t experience so much of this.
Thank you so much! I've always been interested in sound effects and everything related to sound, I'm totally blind and have perfect pitch and... and I still was tricked by the Deutsch scale illusion! :)
This is where I was lured into your channel. I shall not listen to it again! OK, maybe, when I play it for my wife. I might first have to test listening to this with the surround sound in our living room; I doubt I could get her to wear headphones or not the kind I would have available in the living room. As you may be able to surmise from this. No, she will not come into my office and use my excellent headset there. She always reacts as if I am a spider luring her into my web. 😕 "Oh, meh!" she said, listening through the surround sound in the living room. (He hypothesized from experience!) Shhh! She hates it when she knows I have hearing problems with tinnitus, and I show her how bad her ears are! ;-)
I could not for the life of me see the chair going any other direction than left
“illusory continuity/discontinuity” - any perceived continuity is an illusion, the wave shape MUST change to produce the short noise if they are generated by the same source.
Thats what I was thinking.. especially since the interruption was basically white noise, picking out the existence or nonexistence of the constant tone seems irrelevant to me.
*illusory continuity/discontinuity* what about hearing a continuous tone for the first and a non-continuous tone for the second?
The octave illusion was strange for me. I'm right-handed but by default I heard the higher pitch on the left, and I didn't manage to switch right until the flashing note symbols hinted that way (though after that I could switch without them). Then when it was slowed down, and you could clearly distinguish what was happening in each ear, it still felt left-leaning. The two ears' channels were readily distinguishable, but within each ear's "sound-stage", the higher tone sounded a bit further left in both ears. It felt like roughly a 30° angle off vertical. Which itself is a strange thing to say since it conflates "high" and "low" pitch with vertical spatial position.
5:59 pure audio chaos. Sounds like someone fell asleep and left the arpegitator on.
Thank you for sharing this golden ifno!!!
I discovered Nonlinear Pitch Perception as a kid on our piano :) Never knew it was a thing until today
Cette série de vidéos est géniale !
Interestingly, after my fall/TBI/stroke and the initial deafness, I found that I have what I would call Cocktail Party Syndrome -- I simply cannot differentiate readily between two voices simultaneously commanding my attention. Whereas, of course, with the Cocktail Party Effect, people can usually differentiate and shift their mental focus readily between two (or several) separate voices.
I'm similar, but for me it's just due to being middle-aged, AFAIK.
[0:49] One of my headphones ear is broken, so... tverything was on the right.
The illusory dis/continuity was odd for me, because I could correctly tell for both cases when the tone was broken vs not... wonder what that says about my neurons LOL
This sounds like what goes on during my hearing tests. I can just hear a slight difference in the tone/pitch, but my ears/brain precieve it as two different sounds.
Is it strange that during the octave illusion I kept focusing on the G tone (2nd harmonic) which seemed to stay in the middle?
Fascinating, I heard the illusory discontinuity as broken, and the illusory continuity as continuous.. interesting
mine was the opposite, the first one i could tell it was continuous and the second i could tell was broken
I’m loving the ‘whoop-de-doop’ over here.
The Deutsch scale illusion (7:01) broke my brain.
Yeah, that's a good one. :-) She's got a lot of good ones.
octave illusion makes me wanna play portal
For the Octave Illusion, I couldn't hear a high/low bias in either ear; I heard both in both ears. I'm right-handed. And I don't have sound enhancements on. And I'm using stereo audio in Skullcandy Crusher headphones.
I really needed to focus on the chair illusion when he made it to the opposite direction, at first i just thought i was looking trough the chair and seeing the legs, but still rotating the same way as before. Like it was a ghost chair
no idea why but the cocktail party effect fucked me up, like I had the sudden urge to start shouting at my pc
Huh... I've been using some of these tricks in my music and I didn't even realize it... This is enlightening
Now I know why parties are acoustic overkill for me, my brain just cannot single out one voice to listen to. its just garble garble xD
Thanks for these videos, they're super interesting!
Interesting... i'll use this to my advantage on my compositions.
I literally could not see the chair rotating clockwise in any scenario
Octave Illusion: I always hear both notes on both sides; always. What does that mean?
I could only hear the low tone, but I heart an illusory tone an octave above the high tone.
ADHD or Autism possibly. I'm the same way
It means u have to switch to stereo from mono
@@JOEBOBSTANTON buddy, buddy, no...
@@robbietremblay9745 no it doesn't.
The glissando illusion worked for me, even though I was hearing it through only one earbud.
I can observe the chair as the "wrong way", when you were showing the shading of the chairs. It looks super wierd.
9:52 I HAVE CENTRAL AUDITORY PROCESSING DISORDER :crying
About the last example: The noise is able to mask the tone, so I would assume, that the tone is simply masked and not real interrupted.
I'm right handed for literally everything, but for the octave illusion, I heard the higher note on the left side
A bit of deja vu here. I think Steve Drews used cambiata in his "Waterwheel" composition on Mother Mallard's first LP. Also, I think Klaus Schulze used deutsch scales in the into to his piece "Crystal Lake" from Mirage.
