  • the shepards tone was fake :-[ i skipped forward and backwards and it got higher and higher rather than staying the same. When i went backwards it went lower, meaning its fake...

  • Is there anyone else here who realized that your preception of tempo completely changes when your quite very drunk? Sometimes when I walk home absolutely drunk I feel like the songs I listen to sound like they are played on 1.5 times the speed or even faster and Im like "what the fuck? Has this song always been so fast? That doesnt sound right it sounds way to fast." And then I listen to it the next day and everything sounds completely normal again.

  • When it said it could have psychological effects I was like "yeah of course haha". I mean music always has a psychological or mood effect on you and I thought this was what they meant but man that thing made me feel so uncomfortable after like 10 seconds already.

  • The right ear left ear one freaked me out. When I listened to it with one earphone, there was no alternating, just one constant octave tone. Then I listened with both, heard the alternating, and now even with one earphone I can’t hear it how I did before.

  • The Octave trick really messes with me. I am left handed in a lot of ways but technically right hand dominant, as i only write and eat left handed. My brain can't make up it's mind about whats going on. First i heard two octaves that were bouncing left and right in alternate directions, then i couldn't tell which was high and which was low, and then it just blended into a mono sound of octaves mixing in and out of one another. very weird.

  • For the one in the middle, that they seemed the most different about, I hear a high G and a low G (I'm taking Eddy's word that it's a G); the difference is that the low G is *steady*, while the high G goes on and off. And when the high G goes off, people hear the low G, and think the low G came on, when in fact the low G is always on, it's just that the high G went off. If you listen closely, you can hear the low G steadily present thruout the entire clip, but the high G going off tricks people into thinking the low G comes on, even tho it was already on. I don't hear any motion, only a steady low G and a beating high G, but then I'm using two shitty speakers, not headphones. I have no idea what Eddy hears when he describes a semitone below the high G, as far as I can figure it's only the two Gs, in an octave.

  • I love how different everyone is. I could tell with the first two illusions that they were layered. Couldnt get the beep-boop ones at all, and the picture of the dog in the garden popped out to me immediately. Like I was seeing a complete picture not blobs. Had the same result as the guys for the octave illusion. Heard up for the paradox. Couldnt hear the piano words without subtitles which was a cool one.

  • For the "talking piano" - seeing the words certainly helps - but the sounds are pretty much actually there. It's just a Fourier transformation of the speech recording (i.e. finding the amplitudes of different frequencies in the overall sample over time) mapped onto the (relatively coarsely gained) notes on a piano. Amazing stuff.

  • Actually Shepherd scales are not really that much an illusion to trained ears. Because although they imply the notion of falling or rising their nature creates a periodic chance in tone color. So for the trained ear that so called illusion does not actually work.

  • So for part of the video I was listening through a Bluetooth speaker, but it’s only one of a 2-speaker set. They each play one of the 2 different channels of sound that make up surround sound (the right channel and the left channel.) During the octaves illusion it sounded like it only played one note the whole time, no going on and off like with my earbuds, it was consistent. And I just thought it was cool that sound can get split up so weird

  • I can definitely hear two defernet notes I don't have perfect pitch so I can't tell if it's octives or not but the way the notes sound it's more like that the one is constantly over lapping the other maybe that's why Eddy is getting confused. But what do I know.

  • Guys... here's a challenge. Try to play the shepard tone with two violons! First one of you would play from note X and slowingly slide to the upper octave Y while playing decrescendo. The second of you will do the same, but starting a bit later. I'm pretty sure it can be done, though it may require some PRACTIIIIIIICE 😆

  • The last one has a lot more musical ones that can be found on NLflow. My favorite one is the Bohemian Rhapsody one, by the time you reach the operatic section you can hear the voices, including Roger Taylor's falsetto "meeeeeeee". I can hear that with no subtitles. I think it also doesn't translate well in spoken format as you need the subtitles to hear the illusion of the piano "talking".
