One interesting thing I found while watching this video: I was watching it on a home theater setup that could decode Dolby Surround stereo to 7.1 surround signal. Because the music needed to use phase shifts and stuff to move the image around the screen, the sound got sent to random speakers all around me. It was quite an experience.
Brandon Burrows it's about the phasing (delay) between left and right. The scope draws fine regardless of the frequency, so it all can as well be audible. Admitting, I was quite surprised seeing this beautiful image and sound! And the scope with level meters... Beautiful!
JF created a program funded by some kickstarter that you can use to explore these things and see how it is built. There are two ways to do this. One is to generate patterns that really sound like something, the other is basically create the patterns that draw something with high fps, which will then sound like ugly noise, then add on top in higher volume some actual sound that doesn't distort what you see too much, but due to persistence of vision and the phosphor of the CRO, you won't see that much but more of the wanted image, since its drawn over and over again on the same spot, while the audio jumps around. For the fine details and sharp edges, you use frequencies that are inaudibly high (thats why you really need at least 96kHz to have proper images). From those basic principles you can start.
Dennis Lubert oh, thank you very much for that info! I had thought that you need a high end audio source for getting sharp corners without overshooting. But the inaudible content can surely be used.
Please explain how it works because I can't begin to fathom how to go from the sign wave with ends touching the screen edge to 3D rotating spiral balls... and BICYCLES!
Images aren't more than Frequencys and Frequencys are Audible. Every Tube Type TV You watched just gets Frequencys to produce the Image. It's very similar.
you guys should definitely do that! huge fan of real engineering and would love to learn more about (what I imagine is) superposition of waves and the representation of sound in an x-y domain rather than a time-magnitude domain
Real Engineering he mentioned there was some distortion because some cards or devices cant actually do 192Ks/s so my guess is as we cant heard stuff above 20khz at best, i bet that the rest of the bandwith from 20khz to 96khz is used to do the image on the screen. I suppose it works on the fact that phosphor has some retention making an average of the image and so while the XY image from the music would look quite random on the screen, the rest of the image which is above the hearing range goes over the same places over and over again making the trace do the drawing. Maybe im wrong but some like 90Khz carrier with AM modulation for the image sounds like a place where i would start if i had to take a look at this idea. also either the sound is mono and the right channel does the diferential signal or both channels are diferentially modulated, which sounds like the best way imo.
Laharl Krichevskoy sorry for necroposting, but 192kHz is the "sample rate". It is not an actual sound frequency present in the file. The way digital files store audio data has similarities to how video is stored. Video is stored as a series of sequential images to represent a moving scene. Digital sound is stored as "samples" which are sequential snapshots of speaker coil displacement/position. 192kHz sample rate means that in one second there are 192 segments. Higher numbers mean that you get closer to true analog, which moves smoothly from one displacement point to another (whereas digital audio with it's "samples" can only move in steps)
Pixl Rainbow - I am guessing you meant to write that there are 192,000 samples per second. Not only 192 ! The latter would be appallingly bad resolution 😄
7:34 I like this version more than the "working" version. I'd buy an oscilloscope with a limited range just to create these visual echo effects. Makes it look more organic than a boring line drawing.
erm, no - the guy on a bicycle is not amongst the traditional understanding of a triangle plus sine wave, i'm sorry to burst your bubble here but you don't know anything
I have a pair of Beyerdynamic DT 770 Pro's hooked up to a cheap amp and connected to my laptop. I did not expect the demo to make my ears and brain tickle. I don't even have my EQ turned on. This is very pleasant!
Just realized when I watched it for the 2nd time that those who say it's a vectorscope are actually wrong. Calling them that is marketing stuff. A vectorscope always needs a stable reference signal in order to display the color vectors (hence vectorscope). But neither of the right nor the left channel of audio can count as reference signal. The term oscilloscope is correct, it's just the rarely used XY mode, usually YT mode is used. If you use a real vectorscope you won't be able to display those signals, since they use color reference signal phase stabilizers that would interfer with the audio signal. Also they are not made for audio frequencies but for 3.19 to 4.33 MHz signals.
A vector scope shows phase between two (or more e.g. 5.1 sound) while an oscilloscope shows signal amplitude versus time. Vector scopes are typically used in broadcasting and mastering to check phase. An oscilloscopy with X-Y option can function as a two channel vector scope. You may call it marketing, but typically they are different devices used in different applications.
mind blown. Always wanted to dig deeper into oscilloscope tech, they have seemingly fallen out of practical use even in technical industries so i've never felt the need to go deeper than a wiki page or two. As with many things you feature here, hipstery folks like myself will surely be sporting these in a half decade or so.
I'm 50 years old with an HND in music tech a d a professional musician, and I was REALLY surprised how the music translated to the oscilloscope, love this video - every day's a school day! Or is that old sk00l 😊
A cool little side-detail of this is that you can actually embed some graphics and shapes into normal music, without it being audible at all. I've overlaid a binary message and some Lissajous patterns into some random music just to test it, and, well, the binary message could be recorded from an oscilloscope, yet the music sounded completely normal. Useless? Yes. But, neat? Yes!
I'm blown away with how varied this channel gets, it's awesome. Great work techmoan. I also prefer your oscilloscope because it gives the images a cool 3d effect.
Well, its obvious when you realize how these function. The voltage level of channel 1 controls the X axis, and the voltage level of channel 2 controls the Y axis. The 'voltage level' of an audio waveform is expressed by the point on the waveform and how loud the sound is. Drawing with sound is dead easy, now making it sound good... that is where the art comes in xD
You also can create images than can see with an Spectrum analizer but is a diferent way, instead 2D you get 1 dimension of pixels and the time is the second dimension
Scope music will never stop amazing me. Never. Aphex Twin sneaks a picture of himself in one of his tracks using scope music techniques. Friggin amazing. We live in a magical world of coolness :)
I like how the left/right signals sent into the oscilloscope are also being sent as is through the video. As somebody who uses headphones with their computer, it's cool to hear the differing channels used to get the images on screen. For example, as I'm listening, I can tell that the left channel audio was linked to the vertical axis on the oscilloscope, with right channel feeding the horizontal axis.
I've watched this video probably 20 times and every time I'm absolutely stunned by how astonishing and otherworldly this is. Music like this creating imagery feels like something from an alternate universe or an alien planet.
As the person who possibly started the 'Vectorscope vs oscilloscope' thing I did baulk at the first few lines of the video thinking 'shit, what have I done!' But this is cool, and I've fired up my venerable old Tek 2211 to have a play. Another top video Mat :)
A few dozen people told me that it was a vectorscope so don't worry about it. Since oscilloscope is a more commonly used (if possibly not a perfectly accurate) term I just used that.
Techmoan - fair play! I did get excited this was going to head in to a Dave Jones mashup and you were going to say 'In like Flynn,' 'Bobby Dazzler', 'That's all she wrote' and 'Don't turn it on, take it apharrt'.... Techmoan, Dave Jones and old Tek' 'scopes. Heavens, that's a thought :P
mipmipmipmipmip - Mat rightly hits on it in the video, X-Y mode which with all due is a bit deep for a UA-cam reply. Lots of scopes have an X-Y mode, which is all dandy but the use of an oscilloscope is to show Y/Time. I'm trying to think of a decent analogy sitting here in the pub, give me a minute :P
mipmipmipmipmip to see this in the best possible way as many have pointed out an old CRO [cathode ray oscilloscope] (pronounce it 'crow' to sound hip) is the way forward, digital scopes are phenomenal but this kind of true wave display are where old cathode-Ray machines win by a mile. That's why most electronics types use a digital 'scope but keep hold of an old CRO under the bench as they still spank digital ones in a few arenas. I wouldn't unpick serial protocols with my 2211, I wouldn't use the Rigol for vector display. Tektronics are the 'Rolls Royce' of 'scopes. (LeCroy fanboys need not apply) so Mat has quite a serious bit of kit here!
> the use of an oscilloscope is to show Y/Time. Yes - but also no. We have used oscilloscopes in engineering research, with x-y mode showing the acceleration of an elastic rotor in x and y direction. The result is an orbit and the scope allows you to immediately see what is going.
Never herd of people calling oscilloscopes vector scopes, it is a given that they are vector. Also keep up the Muppet skits, they continue to entertain.
As the name implies oscilloscopes are normally used for looking at oscillations. For that you want the X axis to be time. Vector displays (or Vectorscopes) were used to display all sorts of things but went out of fashion when memory became cheap enough to put an entire image scan in memory. Great examples of vector displays were Atari Asteroids, the Vectrex home computer game and all sorts of 1970s test equipment such as HP Spectrum analysers that cost as much as a house. Of course now modern oscilloscopes do everything in pixels as an LCD display is more versatile and costs less to make than a decent CRT.
I know the other methods are cleaner, but there's something so much cooler about watching them on your Oscilloscope. I just really like the way it breaks and yet holds enough consistency that you can tell what is happening, it almost makes it feel more.. intense? And like I can *feel* that it's all from sound even in the visuals? Meanwhile the clean versions feel a bit.. Stiff? Sterile? The chaotic yet controlled feel of the extra lines and the breaks on your device just felt a lot more raw and I love it. If I dip my toes into this music form ever, I definitely want to recreate *that* aspect of it. The lines being unstable, imperfect, and yet you can understand what's being portrayed still. I like that idea.
The old console versions of Atari Asteroids used what in effect was an oscilloscope type display (but using a standard monochrome CRT) instead of a standard CRT monitor (with the normal timebase) . This meant the CRT spot was effectively drawing the rocks, spaceships & scores etc. by having the game processor control the X & Y postions and switch the beam, rather than produce a standard video signal for a standard raster scan monitor.
Whoa, awesome video! Immediately brought to my mind the fact that someone wrote a oscilloscope renderer for Quake, and I was really satisfied that you linked it here for everyone! :)
GustavTheGoat you wouldn't be able to do that because these oscilliscopes show a modified version of the audio waves, and this music was made specifically for the oscilliscope to display. If you put it a different song it would just come out a random mess, unless it was designed for the oscilliscope.
2:06 "I did switch it on just to see if it was working but it made a big bang and lots of smoke came out of it"... This is a common thing: Most electronic equipment has a filter capacitor at the mains input that's connected straight across the live and neutral lines. Over time, those capacitors dry out and make a short circuit, so when you plug the device in and switch on the power: Bang! Once you had a big bang, the device will probably work okay if the rest of the electronics are alright (but other capacitors may have dried out too, especially if you get something from after 1992 or so). You may have to change the fuse though. I you know how to recognize these "explosive" filter caps (usually it's a yellow and/or translucent part near the mains input) you can cut them off before you plug in a "new" vintage device to the mains next time. They work fine without them and sometimes when they blow up they can make quite a mess with chemicals spraying around. Make sure you're cutting off the filter capacitor (again: connected between live and neutral) and not anything else, of course. And obviously do that while it's not plugged in. By the way: funniest muppet ending ever! :-)

The only thing that went through my mind when the demo came up was: "HOW?"... How do you even do that kind of stuff without it sounding like random noise? Jerobeam must be a genius!
what i was looking for was just horrible computer generated noises to make pictures on an oscilloscope i never expected actual MUSIC. this was awesome!
That was just excellent! I've never seen music being played through a scope like that. Very fascinating to see how the audio input denotes X/Y coordinates for the tube to display what almost amounts to a 3D image. Plus the music sounded cool as well. Great video!
Revising this old Techmoan video and gosh I'm reminded how I missed the muppets!! I understand why he stopped having them, but still I keep hoping to see them again even if only for Christmas! ;-)
Great video. I've used an oscilloscope for electronics repair for many years but have never heard of using one for generating an image based on music. I'll have to give it a try. Thanks for posting it.
I love the way the sound makes pictures on the screen, what about if you had a CRT display and a receiving circuit then someone could somehow take the images from a movie camera turn them into a waveform and transmit them from a distance to the CRT receiver then it could reform the the original footage to view at home.
In one way I'm thinking - Isn't that idea already invented, and called television? But on the other hand, when the television was analog, the image frequencies sent through the antenna cable wasn't audible. Frequencies in MHz isn't hearable. So what you're looking for is basically a television that's slightly limited, due to its limitation in bandwidth, and that the frequencies producing the image is also the frequencies that you'll hear.
Judging by how YT's algorithm works, Zac Gobshite's subscribers would have far exceeded Techmoan's by now (if Zac's channel were a real channel in 2016).
My mind just completely blew out of the top of my head - that is amazing! I've been into audio for three + decades and had never seen something like this before. Great Video!
Hello Techmoan, I am a subscriber of yours from a while back, and I have recently started catching up on your videos again. I just watched your "DCC and elcaset" video, in which you briefly mentioned mp1 format audio. It made me realize that there aren't really any good videos out there that compare mp1, mp2, and mp3 format audio. I was wondering if you would consider doing a video on that subject, with the technical details and pros/cons of each format, and possibly even audio samples (and yes, I know it wouldn't sound the best on youtube, but still). I'm not really sure if it's "your area" or "your thing" but I just wanted to ask about it in case it was. Eagerly awaiting a reply, -Sotolefish
Fabulous! I've wanted to do that for years, and now you tell me that there's even music especially designed for the purpose of display on oscilloscopes. Great!
Had no idea this was even a thing until this video. Very neat indeed. Top quality production as well... I feel like I could watch a Techmoan video about paint drying... he keeps things interesting in his presentation by going about a product inspection in the same natural way any intelligent person would... and he shows you the mishaps and complications along the way. This style is very inter-relatable... thus why he's approaching a million folks subscribed. Nice work Techmoan... please make a video about the dehydration of wall pigment, thank you.
I'd noticed the 760 lurking in the background of one of your other videos and wondered what you were going to do with it, now I have serious scope-envy! 8-) As the unit is designed for professional audio the levels it expects to see are higher than consumer audio devices deliver. There are numerous boxes available to convert levels and go from single-ended (unbalanced) to balanced; this one is particularly neat www.rdlnet.com/product.php?page=53 If you use one of these the display will be larger and the bargraph meters will also indicate more accurately. I really enjoy your channel!
Damn incredible! I'm so glad've I found your channel! Everyday I learn that I know so little even I love 70-80's and it was "my time"... But osciloscope graphics is something I saw year or two ago, but have no idea there was so much more about it! Thank you!
One of the first programmes I wrote for my TRS-80 back in high school was one that read the audio data from the cassette interface (the computer had tape input instead of disc drives) and displayed it on the screen. I called it LightShow and I had great fun running my stereo aux output to the cassette input and watching the display change with the music.
I'm something of a habitual lurker on UA-cam; I never normally comment, even on channels I adore - but I am compelled to tell you just how great your Zac Gobshite skit is. Absolutely perfect. Please let's see him again!
Thanks for the heads up on oscilloscope music!!! 😂 Bro, I absolutely enjoy ALL of your reviews on these neat retro ( old school ) technology. I've actually had a chance to experience many of these devices in my childhood. I'm 51 years of age. Thank you again for the memories. yes I've subscribed to his channel too. look forward to playing with vector scope again.

As the person who possibly started the 'Vectorscope vs oscilloscope' thing I did baulk at the first few lines of the video thinking 'shit, what have I done!'
But this is cool, and I've fired up my venerable old Tek 2211 to have a play. Another top video Mat :)
A few dozen people told me that it was a vectorscope so don't worry about it. Since oscilloscope is a more commonly used (if possibly not a perfectly accurate) term I just used that.
Techmoan - fair play! I did get excited this was going to head in to a Dave Jones mashup and you were going to say 'In like Flynn,' 'Bobby Dazzler', 'That's all she wrote' and 'Don't turn it on, take it apharrt'....
Techmoan, Dave Jones and old Tek' 'scopes. Heavens, that's a thought :P
mipmipmipmipmip - Mat rightly hits on it in the video, X-Y mode which with all due is a bit deep for a UA-cam reply.
Lots of scopes have an X-Y mode, which is all dandy but the use of an oscilloscope is to show Y/Time.
I'm trying to think of a decent analogy sitting here in the pub, give me a minute :P
mipmipmipmipmip to see this in the best possible way as many have pointed out an old CRO [cathode ray oscilloscope] (pronounce it 'crow' to sound hip) is the way forward, digital scopes are phenomenal but this kind of true wave display are where old cathode-Ray machines win by a mile.
That's why most electronics types use a digital 'scope but keep hold of an old CRO under the bench as they still spank digital ones in a few arenas.
I wouldn't unpick serial protocols with my 2211, I wouldn't use the Rigol for vector display.
Tektronics are the 'Rolls Royce' of 'scopes. (LeCroy fanboys need not apply) so Mat has quite a serious bit of kit here!
> the use of an oscilloscope is to show Y/Time.
Yes - but also no. We have used oscilloscopes in engineering research, with x-y mode showing the acceleration of an elastic rotor in x and y direction. The result is an orbit and the scope allows you to immediately see what is going.
This is the coolest thing I've ever seen in my entire live.
Never herd of people calling oscilloscopes vector scopes, it is a given that they are vector. Also keep up the Muppet skits, they continue to entertain.
As the name implies oscilloscopes are normally used for looking at oscillations. For that you want the X axis to be time. Vector displays (or Vectorscopes) were used to display all sorts of things but went out of fashion when memory became cheap enough to put an entire image scan in memory. Great examples of vector displays were Atari Asteroids, the Vectrex home computer game and all sorts of 1970s test equipment such as HP Spectrum analysers that cost as much as a house. Of course now modern oscilloscopes do everything in pixels as an LCD display is more versatile and costs less to make than a decent CRT.
I know the other methods are cleaner, but there's something so much cooler about watching them on your Oscilloscope. I just really like the way it breaks and yet holds enough consistency that you can tell what is happening, it almost makes it feel more.. intense? And like I can *feel* that it's all from sound even in the visuals? Meanwhile the clean versions feel a bit.. Stiff? Sterile? The chaotic yet controlled feel of the extra lines and the breaks on your device just felt a lot more raw and I love it.
If I dip my toes into this music form ever, I definitely want to recreate *that* aspect of it. The lines being unstable, imperfect, and yet you can understand what's being portrayed still. I like that idea.
The old console versions of Atari Asteroids used what in effect was an oscilloscope type display (but using a standard monochrome CRT) instead of a standard CRT monitor (with the normal timebase) . This meant the CRT spot was effectively drawing the rocks, spaceships & scores etc. by having the game processor control the X & Y postions and switch the beam, rather than produce a standard video signal for a standard raster scan monitor.
Whoa, awesome video! Immediately brought to my mind the fact that someone wrote a oscilloscope renderer for Quake, and I was really satisfied that you linked it here for everyone! :)
Step 1: get that
Step 2: get xlr cables
Step 3: play some music
Step 4: you have an 3d intro
GustavTheGoat or u could record in the emulator
then it could easily sync the music in the intro
Step 5: ???
Step 6....
GustavTheGoat you wouldn't be able to do that because these oscilliscopes show a modified version of the audio waves, and this music was made specifically for the oscilliscope to display. If you put it a different song it would just come out a random mess, unless it was designed for the oscilliscope.
GustavTheGoat exactly what i was thinking
except the picture things dont work.........only like the squares and some of the circles but the circles are not the same looking
2:06 "I did switch it on just to see if it was working but it made a big bang and lots of smoke came out of it"...
This is a common thing: Most electronic equipment has a filter capacitor at the mains input that's connected straight across the live and neutral lines. Over time, those capacitors dry out and make a short circuit, so when you plug the device in and switch on the power: Bang!
Once you had a big bang, the device will probably work okay if the rest of the electronics are alright (but other capacitors may have dried out too, especially if you get something from after 1992 or so). You may have to change the fuse though.
I you know how to recognize these "explosive" filter caps (usually it's a yellow and/or translucent part near the mains input) you can cut them off before you plug in a "new" vintage device to the mains next time. They work fine without them and sometimes when they blow up they can make quite a mess with chemicals spraying around. Make sure you're cutting off the filter capacitor (again: connected between live and neutral) and not anything else, of course. And obviously do that while it's not plugged in.
By the way: funniest muppet ending ever! :-)
There were a few other issues as well, however it served its purpose as a donor well and now lives at the recycling centre.
Techmoan Should've ate it
that is hands down the sickest audio display/visualization I have ever seen. I want one now
I think the imperfections in your rebuilt one made it even better with the wiggles and wobbles it had
This is the best ending to a video you've ever made.
It seems some like this one but others really dislike it. I'm on the fence.
Well it made me laugh.

This reminds me of the "Jim and Derrick" episode of Tim and Eric Awesome Show where they take the piss out of stupid trendy MTV skater shows that have the same sort of visual interstitial text and sound effects every other second.
Best one ever, Mat.
Weird it sounds half decent, you'd expect it to sound more like a phone modem.
The modulation in this audio is similar to the modulation happening with a modem. Both use the modulation to encode data
sounds full decent
Oscilloscopes don't have speakers
The only thing that went through my mind when the demo came up was: "HOW?"...
How do you even do that kind of stuff without it sounding like random noise? Jerobeam must be a genius!
He used the oscilloscope music
Don't ever stop putting the puppet sketches at the end! love it every time!
this genuinely memorized me to the point i was re-watching it at different speeds over and over and over again
I need this in my life.
The displayed graphics even make sense!
Osmosis that's the point
Phisk
Yes, I should have watched it a bit further than 6 min before commenting. Mistakes were made ;)
You are killing it my friend
This is AMAZING! I want one.
"Aww, this chap's just too old to be on UA-cam"
Says the guy with a Commodore SX-64 as his main computer.
Guess it got upgraded. Amiga 500, next?
what i was looking for was just horrible computer generated noises to make pictures on an oscilloscope i never expected actual MUSIC. this was awesome!
this is literally the coolest thing ive ever seen
This video has actually blown my mind
Oscilloscope Music, my new FAVORITE THING!!
One of the nicest looking Tektronix scopes I have seen, very good condition
That was just excellent! I've never seen music being played through a scope like that. Very fascinating to see how the audio input denotes X/Y coordinates for the tube to display what almost amounts to a 3D image. Plus the music sounded cool as well. Great video!

@Galaxy Recordz Vaporwave is a genre of music, not an artist.
I didn't even know that this was a thing. And I'm an electronics and network engineer.
I honestly think you should dedicate a channel to your muppet (whatever they are) skits

We LOVE the muppets!
Subscribed!

Why are all of the puppets missing from UA-cam Pedant?
Revising this old Techmoan video and gosh I'm reminded how I missed the muppets!! I understand why he stopped having them, but still I keep hoping to see them again even if only for Christmas! ;-)
Great video. I've used an oscilloscope for electronics repair for many years but have never heard of using one for generating an image based on music. I'll have to give it a try. Thanks for posting it.
I love the way the sound makes pictures on the screen, what about if you had a CRT display and a receiving circuit then someone could somehow take the images from a movie camera turn them into a waveform and transmit them from a distance to the CRT receiver then it could reform the the original footage to view at home.
In one way I'm thinking - Isn't that idea already invented, and called television? But on the other hand, when the television was analog, the image frequencies sent through the antenna cable wasn't audible. Frequencies in MHz isn't hearable. So what you're looking for is basically a television that's slightly limited, due to its limitation in bandwidth, and that the frequencies producing the image is also the frequencies that you'll hear.
ian gee
Haha, my bad... People actually say these things and mean it! I really missed the irony in this one! 😂
I have not been entertained by something like this for years... I watched it with my mouth open, like a child :)
I was the same. Particularly the butterfly towards the end. Just astounding.
same here
That's some pretty dank satire at the end there... bonus!
The only thing off is the number of subscribe requests : way to low !
Judging by how YT's algorithm works, Zac Gobshite's subscribers would have far exceeded Techmoan's by now (if Zac's channel were a real channel in 2016).
My mind just completely blew out of the top of my head - that is amazing! I've been into audio for three + decades and had never seen something like this before. Great Video!
I love the presentations... But the Passive-aggressive Puppet Theatre at the end had me howling. Absolutely hysterical. Keep it up, Techmoan! 😂
That beat though at 5:36
Brian Rock Jeroboam Fenderson - Planets. look him up.
Hello Techmoan,
I am a subscriber of yours from a while back, and I have recently started catching up on your videos again. I just watched your "DCC and elcaset" video, in which you briefly mentioned mp1 format audio. It made me realize that there aren't really any good videos out there that compare mp1, mp2, and mp3 format audio. I was wondering if you would consider doing a video on that subject, with the technical details and pros/cons of each format, and possibly even audio samples (and yes, I know it wouldn't sound the best on youtube, but still). I'm not really sure if it's "your area" or "your thing" but I just wanted to ask about it in case it was.
Eagerly awaiting a reply,
-Sotolefish
It's a bit technical for me..it would need someone who understands it better, I'm more of just an end user.
Start - Aww yeah this is kinda of interesting.
5:00 - Okay that's fucking incredible! I NEED ONE!
😀🤔😨😱🤤 I want it so badly!!!!!!!!!!!!!!!!!!!!!!
Fabulous! I've wanted to do that for years, and now you tell me that there's even music especially designed for the purpose of display on oscilloscopes. Great!
I love how he managed to make a cool animation while making the actual audio sound awesome at the same time.
5:30 that sound is fuckin nice
"Today I'm going to show you how to draw mushrooms with an oscilloscope"
5:08 I LOVE THIS NEW DUBSTEP
One of the best recomendation UA-cam made it for me. ❤️
Jesus christ this is one of the most satisfying random recommended youtube vids I've ever randomly clicked on
omg thats so cool! had no idea you could do this with a scope
Awesome as Fu**.
Also loved the sarcastic puppet clip at the end.
That puppet thing made me LOL
Had no idea this was even a thing until this video. Very neat indeed. Top quality production as well... I feel like I could watch a Techmoan video about paint drying... he keeps things interesting in his presentation by going about a product inspection in the same natural way any intelligent person would... and he shows you the mishaps and complications along the way. This style is very inter-relatable... thus why he's approaching a million folks subscribed. Nice work Techmoan... please make a video about the dehydration of wall pigment, thank you.
This is really waaaay too cool honestly it makes me want to get into this like seriously.
*5:37** - **5:52** Sounds reaaallyyy good! ~>~*
I think that 6:10 souns good
The melody is from here m.ua-cam.com/video/h9yvb03R2qs/v-deo.html
Rex is bro I’ve heard a song that has that in it
I could see someone putting this in a sci-fi movie like the original Tron
I'd noticed the 760 lurking in the background of one of your other videos and wondered what you were going to do with it, now I have serious scope-envy! 8-) As the unit is designed for professional audio the levels it expects to see are higher than consumer audio devices deliver. There are numerous boxes available to convert levels and go from single-ended (unbalanced) to balanced; this one is particularly neat www.rdlnet.com/product.php?page=53 If you use one of these the display will be larger and the bargraph meters will also indicate more accurately. I really enjoy your channel!
Thanks for the info.
It's very cool that these effects are all hardware generated. These days software audio-visualizers are two-a-penny, but this is so much cooler.
Damn incredible! I'm so glad've I found your channel! Everyday I learn that I know so little even I love 70-80's and it was "my time"... But osciloscope graphics is something I saw year or two ago, but have no idea there was so much more about it! Thank you!
One of the first programmes I wrote for my TRS-80 back in high school was one that read the audio data from the cassette interface (the computer had tape input instead of disc drives) and displayed it on the screen. I called it LightShow and I had great fun running my stereo aux output to the cassette input and watching the display change with the music.
I'm something of a habitual lurker on UA-cam; I never normally comment, even on channels I adore - but I am compelled to tell you just how great your Zac Gobshite skit is. Absolutely perfect. Please let's see him again!
So oscilloscopes music is just some dubstep amd good ole wubs
Thanks for the heads up on oscilloscope music!!! 😂 Bro, I absolutely enjoy ALL of your reviews on these neat retro ( old school ) technology. I've actually had a chance to experience many of these devices in my childhood. I'm 51 years of age. Thank you again for the memories. yes I've subscribed to his channel too. look forward to playing with vector scope again.
What a result repairing the old one from a scrap new one. Good video.
