I | don't remember for sure which one I could hear at first, but I | think I only heard "green needle", which was higher pitched, | and it took me a lot of concentration to block that out and | focus on the lower pitch enough to be able to parse out some | semblance of speech. If my recollection is correct, my troubles | with the lower pitched sound is a little ironic because I play | bass and often try to point out bass parts I like to my | fiancee, but she sometimes has trouble parsing out exactly what | I'm referring to due to not having had any musical training and | it not being as obvious to her which part is the bass when I'm | showing her a song with lots of different guitar and keyboard | tracks and lots of heavy bass drum. | AlbertCory wrote: | Funny about them: I can hear the words _either_ as "Mexican | lucky" or "to get lucky" (the correct lyrics) depending on what I | want to hear.

It's the other voices | that are progressing. | mergejoin wrote: | commenting, in case you figure it out | MAGZine wrote: | it sounds like you're referring to Daft Punk's "Giorgio by | Moroder" from their album "Random Access Memories." The segment | you're describing involves a repetitive chord progression, but | the perceived variation comes from the evolving layers and | elements surrounding the chords. This technique creates a sense | of progression while maintaining a consistent base. | | -- by chatgpt | adamrezich wrote: | for the Robot Rock one, the author should've clarified that it's | not referring to the actual `rock. robot rock` voice part, but | the part where the guitar chords _sound like that_. skip to about | 1:50 in the linked video to hear the robot voice, then listen to | how similar just the guitar chords after 2:00 _sound like_ the | robot voice saying `rock. robot rock.` | ugurnot wrote: | You are right. That part seems a little bit vague, I will | update it. | brookritz wrote: | ...and the author should have clarified that this Daft Punk | song is copied from a 1980's single: | https://www.youtube.com/watch?v=5b0jWlPtP5o | spondylosaurus wrote: | Isn't Daft Punk pretty famous for sampling/referencing other | artists' songs? | rtuin wrote: | Yes: https://www.whosampled.com/Daft-Punk/samples/ | rifty wrote: | Sure, but it's worth mentioning that this isn't just a Daft | Punk thing. Electronic music and especially House music | going back to its roots was shaped by sampling great | moments or vocals of tracks into loops and mixing them | together into new tracks on top of a 4/4 kick. | | The funky/disco/french house era was particularly prolific | with sampling though. | veave wrote: | HN discovers sampling in electronic music. | glandium wrote: | Also, in that particular example, I don't think they made the | guitar emit the voice-sounding sounds, but rather generated it | electronically. It's not even obvious that the voice comes from | guitar sounds... it actually sounds like a plain voice with | effects. | | As opposed to, say, Mark Rober's talking piano. | ilyt wrote: | This is a better demonstration of octave illusion, I had no clue | wtf the article meant until I listened to this: | | https://www.youtube.com/watch?v=IMMsK9rjBWo | | But I heard the lower tone in the middle of my head and higher | tone bouncing from left to right. Not the "low on one side, high | on the other side" article mentioned. | | Kinda interesting to think some people might hear completely | different thing in same song... | wantguns wrote: | i have always felt some unexplained effect while listening to | Veridis Quo [1]. the melody start sounding different from the | 0:38 mark, just as the kicks come in. it seems like some | supporting keys are added with the kicks, to make the sound more | full, but at the same time it could be my brain getting tricked. | | sorry for botching the explanation, i have never studied music. | | [1]: https://www.youtube.com/watch?v=TCd6PfxOy0Y | samstave wrote: | I have a weird auditory illusion that happens to me ; I have | tinnitus, and a super weird auditory response thing that happens | to me occassionally: | | So when I cant hear the high-pitched tinnitus squeal (very low | volume, but still hear it) - there is something weird that | happens which is that I can "hear" some sort of radio station - | which plays music in the really faintest and far away sounding | volume... | | The other thing that happens, is that when laying in bed, | attempting to sleep - there are times that when the house makes a | "creak" sound of settling or whatever (you know how your wall may | 'pop' or 'creak' at times - but the weird thing is that it | simultaneously coincides with a pop and a flinch of my body, or | 'sound' in my head. | | There are times when this happens and I get a bright flash in my | closed-eyes... | | Anyone know what this is? Sodium defficiency? or aliens? | SpaceNugget wrote: | I don't hear radio stations, you might want to get your antenna | checked.

Probably a whole catalog of tricks. | whiddershins wrote: | Yes | jnurmine wrote: | When I was 14 years old, I noticed how pure saw waves make fast | transient sounds go "whooshy". | | 1. Play a pure saw wave sound for several seconds, it has to be | loud (use headphones), then | | 2. hit the keyboard keys, or snap your fingers, or make other | sounds with fast transients, and the transient is no longer | snappy, it "whooshes". It's hard to describe but there is like | a flanging effect on it. | | I guess there is some scientific name for this phenomenon, but | I don't know what. | v64 wrote: | Happens all the time. Most common one for me is when you're | making a patch on a synth and by chance dial in those | frequencies that align with formants (similar to the Robot Rock | effect the post mentions). | | Yesterday I was working on a bass drum beat, and after adding | some synths playing on top of it, I started to hear the bass | drum echo. So, my first thought was I had accidentally enabled | some kind of reverb or echo effect on it while I was setting up | the synths. After confirming I hadn't and isolated the track to | ensure the bass drum was sounding as intended, I chalked it up | to some weird illusion between the synths and drum that was | making it sound like an echo. I know it's not there in reality, | but I can't unhear it. | | In this case, I went back and added a little echo to the drum | to make the effect intentional, which turned out to sound good, | but sometimes I'll try to make the illusion reality and it | doesn't have the same effect. | mergejoin wrote: | would you mind sending a mp3 of that effect? just curious :) | metamet wrote: | I always wonder if it's some odd thing going on in the DAW. | | Would you be willing to export that track as two tracks--one | with drums and one with synth? Then listen to them solo, then | run them together (with WAV files instead of | instrumentation)? Would be neat to have that illusion | confirmed rather than it being a DAW artifact. | Groxx wrote: | > _Open the song Aerodynamic and fast-forward to 2:28, start | listening to the passage. I hear the higher pitch on my right and | the lower one on my left ear. What about you?_ | | tbh I'm not sure which notes they're referring to here. There are | a couple overlapping high/low pairs in that segment, and I'm not | sure which is the octave/those frequencies. | | One seems like higher is more in my left, but it clearly follows | the left speaker on my headphones. The others warble around for | me, though I'm pretty strongly right handed. | | --- | | Even after reading and listening to | https://en.wikipedia.org/wiki/Octave_illusion I'm totally lost as | to what this post or wikipedia are describing. Are people hearing | like: left ear right ear | ------------------------- high | (nothing in right ear) low high | low | | or something else? I mostly hear: left ear | central right ear | -------------------------------------- high low | low low low high high | low low low low high | | I'm definitely hearing "low" while hearing "high" on the opposite | ear, though it feels like there's a basically constant central | "low" as well. The high tone clearly moves between sides. | | Maybe worth mentioning: I've had a hearing test in the past year | and I'm essentially completely balanced, so there likely isn't a | tone-deafness issue on one side that could cause a reception | imbalance. Could the illusion just be hearing damage? And then | handedness just follows which ear takes more damage due to more | noisy things happening / less protection on that side? That could | also explain why left-handed people are less strongly sided, as | they're forced to do things more balanced due to right-hand-only | stuff existing. | gabereiser wrote: | people are hearing what you hear. It's the simultaneous tones, | one low, one high, low in the left, high in the right. It's not | that it's panning (one at a time), it's together (or within ms | of each other when mixed with other techniques). Once you | understand this, then the concept of just flipping it makes | even more sense. Then get creative and flippity floppity the | high/low left/right dance. | Groxx wrote: | That's what the sounds are actually doing though, so what | would the illusion be? | gabereiser wrote: | the illusion is it's perceived as the "same" note/tone. | It's not, and when you dig, you can tell it's not, but when | you're casually listening, your brain here's a "fuller" | note for some reason. The "fuller" comes from the two | octaves being played simultaneously in your seperate ear | holes. | | Like sleight-of-hand, you know it's there but you can't | quite discern it at the time and are gladly surprised by it | but you know it's not real magic. | Groxx wrote: | This sounds like it might be conflating stuff like | vibrato (fast variation in pitch) or even faster. The | illusion in the song and on the Wikipedia page involves | changing the tone only _four times per second_ , there's | no claims at all about both tones blending together. | ilyt wrote: | I don't hear that. I hear constant low tone in both ears with | only high one bouncing around (i.e the ear where high is is | perceiving low one even if it is not there) | Groxx wrote: | * * * | gizajob wrote: | It's the Shepard tone effect running in the background of the | actual notes, which produce a mild illusion that they're | ascending when they're not, but nevertheless they're moving up | and then down in pitches so it's not a brilliant example. I | think the author is a little confused in this short essay about | a few things. His "talking piano" effect is just standard | vocoding, which has made me think this is all fairly new to him | and he's not an expert. | | _THIS_ is a talking piano: https://youtu.be/muCPjK4nGY4 | ugurnot wrote: | The tone I'm referring to is the alternation between F#3 and | F#4. I think your observation about the Shepard tone is | valid. For the talking piano effect, I remember trying to | play it on guitar to make it sound like "Robot Rock". I | suspect this is in relation to Tethard's example of | accentuation by spectral contrast, but that was a long shot | to include. | | Well, the audio area is full of masters and experts. I make | no claim to be an expert, so you can ignore this writing as | you prefer. | suction wrote: | [dead] | suction wrote: | [dead] | ilyt wrote: | Same for me, just hearing the high tone bouncing around | | Here is better video for that illusion: | https://www.youtube.com/watch?v=IMMsK9rjBWo | | I've heard of an effect where brain synthesises lower tone from | the higher harmonics, might that be reason why I hear the low | tone in both ears at once? | sublinear wrote: | https://youtu.be/1oD2DWf4CjQ | | Com Truise - Fairlight | | I wouldn't call this an illusion as much as an interesting | effect. Put on a good pair of headphones and listen to the intro | at moderately high volume.
