The return of OSCILLOSCOPE MUSIC with the N-Spheres EP

[@Techmoan]

As pretty much everyone has already pointed out repeatedly , it seems I’m using the wrong kind of scope. If you want to view the ‘ n-spheres EP’ I’d *strongly recommend playing the linked KZbin videos or buying, downloading and running the executable* Only those with the correct sort of oscilloscope to hand should bother attempting to play the audio on a real scope, even then it would probably have looked better played on a bigger PC monitor.

[@large65]

Hi, it is not the Scope to blame. The audio interfaces are simply the wrong interfaces. As others already stated, the problem is that the DC component of the signal is filtered out on a normal audio interface. Any DC component is not hearable, only AC components are hearable. In fact a DC component could harm a speaker or headphones (or it could lead to unwanted distortions). There are special Audio-Interfaces that are capable of putting DC out. These are typically used with modular synthesis to produce slow moving (nearly DC) signals to modulate things on the synthesisers. An example would be a Befaco AC-DC Modul (only on second market available). Kind regards

[@MazeFrame]

According to the manual for the 760-scope, there are capacitors in the signal path which block any DC-offset. This results in any DC which would cause lines shifting on the screen to just be stationary.

[@SierraLimaOscar]

Correct. Because that is not an oscilloscope it's an audio analyzer/meter. Very cool device, but not the same.

[@GoatTheGoat]

Yes. His scope is hard wired for AC coupling. The music is designed for a scope with DC coupling.

[@Kalvinjj]

Ain't the audio also AC coupled anyway too? Would just end up the same.

[@simonturnill]

This is the correct answer

[@1dolar1note1]

Every single DAC designed for outputting audio is designed to get rid of any DC voltage on the output. The audio needed to display the visuals properly rely on being able to send out DC signals without getting filtered. Many years ago they mentioned it on their blog, saying they had to modify an audio interface to remove some capacitors IIRC. It's less of an issue of the output not being "high end" enough, it's just not designed to output DC voltages as those are generally bad to have on any kind of speaker. EDIT: What you'd want for this application (or also ones that use modular synths with CV inputs, another more common use case) are "DC-coupled audio interfaces".

[@whitslack]

The unshielded cable is also going to have some capacitive coupling between signal and ground that will tend to filter out DC components. The long wires will also have some inductance that will filter out high-frequency components. I'd love to see the setup that is required to get this music to display on a real scope as intended. I'd bet it's unconventional and nothing the typical consumer of the album is going to have on hand.

[@MichaelThwaite]

I don't see a DC option on the scope either. I think it'd likely need that to support what looks like 2Hz or less.

[@AgentDexter47]

I would second this - either he sound cards/outputs of the devices have a high pass filters, or possibly the scope itself has it. you can try by connecting a fixed voltage like that of an AA battery to scope and if the line is in the middle, then its scope filtering DC component.

[@Craig_Spurlock]

My setup that resulted in perfect results with the first Oscilloscope Music is a Sony BDP-S580 Blu-ray player playing from its stereo line-outs into my Tektronix 2213A. I used the downloaded .wav files. I have not wired up this new EP yet.

[@deepblueskyshine]

​@whitslack This not-oscilloscope, but a "stereo audio monitor" as its original "instruction manual" states on the title page, works over XLR, which is a shielded twisted pair EDIT: and most XLR equipment will take unbalanced/unsymmetrical input signals without any problem (except for losing induced noise protection).

[@wktodd]

Your scope is AC coupled to ensure the display is centred , (it is filtering the very low frequencies). There may be options on the scope to show DC levels or alternatively use a normal oscilloscope in vector (X/Y) mode.

[@AsahelFrost]

This! The problem is not the high-frequency cut-off, it is the low frequency end rolling off that is the issue.

[@EarthSurfer]

This echoes my observation of Mat’s results. The shifting of the whole image indicates this is a low frequency issue. The creators may be using a DC Offset to center the image indicates the display window. Any AC coupling would allow the image to drift from center if there is offset. (Sorry, there is some electronic engineer speak here…)

[@Derpy1969]

AC coupling and filtering was what went through my mind. I think you are on the right track. There’s also bandwidth limitations.

[@bramvanriel1363]

Actually, most DAC’s are AC coupled as well, to prevent damaging speakers. You’d need a DC coupled interface (like for instance, MOTU)

[@felixmoore6781]

@@bramvanriel1363 Actually, the amplifier's output is normally AC-coupled as well. But the filter might have a lower cut-off frequency than the scope.

[@ChrisPonate]

Thank you for keeping us up-to-date on out-of-date technology. Sounds weird, but I mean it.

[@bobblum5973]

That's a very accurate description of Mat /Techmoan. I personally enjoy the way it seems like he's having a conversation with you, the viewer. Other content creators do that as well, but this feels more like he's inviting us on a journey together. 🙂

@@bobblum5973 Its the tech-lovers comfort channel.

[@NashiiraGM]

This this this. I know the image it was making wasn't ideal, but even in this form it was so rad to see is even possible! I loved it.

[@BasementWorkshop]

The visual effects need a DC-coupled signal chain. This is most obvious with the sweeping lines which are meant to slowly move across the screen: AC coupling removes any low frequencies, including the slow movement of the lines, with the result that they just sit in the centre of the screen. The most likely culprit is the oscilloscope which appears to be specialised for audio and therefore almost certainly uses AC-coupled inputs. That would explain why changing the DAC has no effect. A general-purpose oscilloscope would have switchable DC/AC coupling.

[@orcapilot-o8n]

I think the issue is in the sound output; I have a Hitachi V-212 and notice the DC coupling on that scope as well.

[@yeoldestuff]

The EP is probably designed for proper lab grade oscilloscopes, I'm pretty sure those stereo visualisers all have auto-centering which would mess up the visuals.

[@1dolar1note1]

I would find it very odd if an oscilloscope made for monitoring stereo audio would do things such as manipulating the incoming signal. That's not its job, it just needs to display what goes into it. Tektronix is a brand known for making test and measuring equipment, I'm betting money on the oscilliscope being perfectly fine.

[@dafoex]

This was my first thought. If it's an audio oscilloscope, is it only monitoring signals that the human ear can hear? What @1dolar1note1 says casts doubt on that, though...

[@john_hunter_]

I was thinking thee same thing. It does look like some kind of auto centring system but I know nothing about oscilloscopes. Maybe it is just because it can't access or display the higher frequencies.

[@Pxrchi]

@1dolar1note1 Yeah, I think there must be some sort of highpass filter (or something causing the DC to be filtered/ not as accurate) within the signal chain, the scope itself should be able to produce those visuals. Could also be the signal is getting distorted. I remember seeing those kinds of artifacts (where the lines arent quite matching up during regions of overlap) when either filter or dynamic shaper of sorts was removing/altering the DC.

[@MazeFrame]

@@Pxrchi Took a look into the manual for the 760A, page 145 has the analog-front-end schematic, and as suspected, there is a 10uF capacitor there to block DC-offset.

[@willyarma_uk]

Looks like AC coupling is the culprit. The scope will have a setting for it but more than likely all your audio devices will have series capacitors to block DC.

[@ptravers]

The Tektronix scope has 10 microfarad caps on each (balanced XLR) signal line. It doesn't have DC coupling.

[@huntabadday2663]

I see many people saying that the problem is the scope itself being AC-coupled, which is correct, but what most are missing, is that most audio interfaces are also AC-coupled as to not fry any coils by running dc current through them. To fix the problem, you will need to get an interface AND an oscilloscope which is DC-coupled so the DC is not filtered out of the signal.

[@Craig1967]

You nailed it. Absolutely correct.

This is such an amazing project, I smiled though the whole demo section. No surprise, I also love demoscene stuff, and that executable is basically that.

[@vooveks]

Made me remember the ‘demo in 64k/128k’ exes from the early 2000s - all audio and visuals procedurally generated. Blew my mind at the time. Did a ChatGPT question and got this: “Some notable demoscene groups and productions from around 15 years ago include: Key Groups: 1. Farbrausch - Famous for their demos like: • “The Product” (fr-08): A legendary 64k demo released in 2000. • “Debris”: A highly regarded 177k demo from 2007. 2. Conspiracy - Known for: • “Chaos Theory”: A stunning 64k demo released in 2006. • “Elevated”: An atmospheric 4k demo. 3. mfx - Created highly experimental demos. 4. Fairlight - Renowned in the scene for polished and creative productions. 5. Andromeda Software Development (ASD) - Known for visually and conceptually rich demos. What made these demos special? • Procedural Content: All assets (graphics, music, textures) were generated algorithmically, often using mathematical functions, which eliminated the need for external files like WAVs or bitmaps. • Synthesized Music: They used in-house synthesizers coded to generate music in real time. • Minimalist Code: Extreme optimization to fit everything within the size limit. You can still find many of these demos on sites like: • Pouët.net: A central archive for demoscene productions. • Scene.org: A hub for demoscene files and archives.”

[@lassi4855]

That executable is very demoscene esque. 😄

[@martingibbons2488]

Surely demo scene guys made this to achieve the chip music and tiny files. It screams demoscene!

[@gertk2303]

AC coupling is the magic word here, both in the audio outputs/DAC's and maybe also on the scope inputs. For the display to be correct you need DC coupling on both the audio output and the scope inputs.

[@SiaVids]

I too have spent much time with various oscilloscopes both cheap and high end, different audio sources too and have not had much luck reproducing the images properly. I'm pleased to see that it's not just me.

[@Nightshft42]

On most Oscilloscopes you can select DC or AC coupling on the input. AC coupling will filter out any DC bias. You need DC coupling here to get the "complete signal" on screen. Not sure if your scope offers DC coupling, or if there's any simple way to mod it (typically it should boil down to bypassing a capacitor that's in series to the input line). Also I guess many of the Audio devices will also AC couple on the output, because normally you don't want or need any DC offset. You'd need a Audioplayer/DAC that also includes the DC part of the signal. Nevertheless nice effort and interesting video!

[@cgoad]

Hi Mat. A very Merry Christmas to you and yours! Thank you for all your work and videos. Here's to a great 2025!

[@video99couk]

Some oscilloscopes have fixed AC coupling, and this may be the case here. Put a small battery on the input of the 'scope. If you can't get that to shift on the screen then it's AC coupled. Look for a switch to select DC coupling on it, but if there isn't one, then you'll need a better oscilloscope.

[@wolfgangmaichen1571]

The problem is much more likely on the sound output - virtually all (or all) sound card outputs are AC coupled so the suppress the DC component of the signal. So it is not the scope input.

[@oturgator]

DC is filtered out, video99couk is correct. But also wolfgangmaichen1571 is also correct, it is not possible nowadays to find a DC coupled output, some rare breed RME sound cards or some rare other equipment can do that.

[@roygalaasen]

When I saw the floppy, it was pretty obviously what they had done - created a piece of software that outputs these songs on the fly. I wouldn’t be surprised if they on their end have created a full fledged specialised piece of software to create these kinds of music, while on the floppy, only the player is included to replay what they have created in the DAW style software they have on their end.

[@knibknibknib]

​@@roygalaasenThe scene you're looking for is the "Demoscene". Back in the day they were about maxing out hardware, demoing their programming skills. Now that hardware is so powerful many choose to go small and show off that way. An example is ".kkrieger" released in 2004. It is a first person shooter with sound and music and is only 96k. Pure music and visualization formats come even smaller than that. Lots of programming in assembly, still. This scene is probably the reason we have graphics so powerful these days, lots of crazy hardware and software tricks developed by these enthusiasts.

[@Gadgetonomy]

[@lilithwingett9688]

Use your oscilloscope in manual mode, the scope is trying to find the peak voltage and frequency and hold at those, what you need to do is set the voltage range and frequency range manually.

[@Anon-su8wt]

hi Matt, here’s some unsolicited advice. I asked my electronics engineer (retired) father-in-law. His comment: He isn’t using an oscilloscope; he’s using a fairly ancient Tek 760A, which is an audio xy monitor or vectorscope. It has AC coupled inputs, which is why the signal is centred on the screen, and it also seems to have auto- ranging gain control, so that wouldn’t help either.

[@McShave]

I use a 56 year old x-y scope it works great. The problem is this 760A. For this to work on an oscilloscope or an x-y generator, x-y needs to be for horizontal and vertical. Techmoan's scope works as the Left channel is up and diagonal to the left, Right channel is up and diagonal to the right (or phase to the left-right as the mainal puts it). This is why the converging pictures are ending up mashed together. The scope can never make a clean image no matter how good the signal in is.

[@merashallan]

You need an oscilloscope with DC coupled inputs in XY mode. Yours is obviously AC coupled as things tend to return to the center.

I wonder if (either deliberately or just as a consequence of design) these audio scopes and up normalising/centre-ing their displays? The brokenness of the graphics look like as though are somewhat normalising in towards the centre of the display in a way which breaks layout (which is probably what you'd want for analysis pre-broadcast or similar. It definitely looks like analogue domain rather than digital or D-to-A. Anyway, another great video, many thanks.

[@hrothgar014]

You’re correct. Audio scopes like these are designed to do just that. They are meant for audio quality control and keep the X and Y in the center of the screen.

[@Kalvinjj]

@@hrothgar014 Interesting to note then, that if they're AC-coupling the signal... one thing you cannot test with it is DC offset. Which I honestly would find an important test since you're measuring stuff already.

[@Globoglobitos]

Thanks for this fantastic vid! Great way to start the day

[@konohh]

A merry christmas to everybody. The audio output on the regular audio devices are DC decoupled. Only the AC part (the wiggly bit) is left through. Which is absolutely fine in terms of audio quality for a human ear. For properly displaying oscilloscope music on an oscilloscope, the DC part is mandatory to have, otherwise the result as shown will appear. My best shot of having a high resolution media audio player that is NOT decoupling the DC part was a raspberry pi, equipped with a Hifi Berry DAC and VOLUMIO2 installed. With this setup the very best results were achievable. Some of those results are still available on my channel.

It almost looks like you may have your scope inputs set to AC when it's trying to display DC Like if you connect a battery to the input of the scope with it set on AC, the trace will centre Yes i know audio is supposed to be AC, but worth checking

[@madmodders]

It doesn´t seem to exist a switch for that. Looking at the schematic, you can input the audio into the XLR jacks on different pins. Probably for differential audio signal. One has a 10 uF capacitor in series (pin 3), while the other (pin 2) doesn´t. Perhaps you can use pin 2 in each jack to have the signal DC coupled.

[@goddessesstartrekonlinefle3061]

I imagine the rest of the viewers already pointed out, but the problem is that modern oscilloscopes are designed for electronics work, and with that in mind they include features like auto centering of output. What I would guess your scope is trying to do, is better present the results for analysis assuming the needs of the electronics expert. As far as I am aware most modern scopes are digital analysis tools rather than traditional 'precisely what it sees' scopes (much like you won't find any modern purely analog electronic radio outside niche specialists). Fun to see this, a far cry from my day at University where accidentally creating what looks like breasts when testing a transistor was the height of oscilloscope art he he.

[@scottshedden5094]

Correct display requires DC coupling on the input but *also from the output*. Most low end, but also some high end sound cards/DACs are AC coupled. A MOTU M4 for example has DC coupled outputs and displays correctly on a suitable oscilloscope.

[@Pxrchi]

Not sure if you mentioned it but I believe most of the visuals were produced using a more "oldschool" method if you will, using parametric functions instead of osci-studio or programs alike. Which is absolutely insane to me, I've fumbled around a little before (using reaktor and puredata, both of which are desktop programs), and it was such a pain to try and find the equations that work for producing the visuals I wanted. Especially things like the wave-like distortion eminating throughout things like the hilbert curve, and mapping the hilbert curve to a sphere. Not certain if parametrics were used throughout the whole album/project, but regardless still incredible.

[@rarbiart]

there is AC coupling either on the Oscilloscopes and or the audio interfaces. So you need audio interfaces which go down to 0Hz, in order to provide DC offset, otherwise the horizontal/vertical lines will never be moving slow, but be autocentered. For the scope: Test it with some kind of DC source (battery with a 2 voltage divider resistors/potentiometer) to see if it's DC coupled.

[@videolabguy]

The DAC MUST HAVE a DC coupled output, the scope must have DC response and you must not insert any other audio devices in the line that may be internally AC coupled. Then all will work. Your audio scope is guaranteed to be AC coupled. I use Tektronix 604 and 606 XYZ oscilloscope monitors and they work excellently. I think I paid $10 for the expensive one and the other was a gift. They are not rare and most folks don't know what they are good for. So, easy and cheap to acquire (usually). I also construct small oscilloscopes and video monitors from scratch. I always make the deflection paths DC coupled. Years ago, when I came to terms with the "DC component" of a video signal, I switched to designing direct coupling into every wideband amplifier I build. I only AC couple my video signals for the purpose of performing a proper DC restoration. That is that video blanking is absolute zero volts DC, sync is always a negative voltage and video is always positive.

This oscilloscope music reminds me of that guy who took 3.5" hard drives and made them produce music with the write arm. That was also something that was pretty neat.

Good to know the original team is still working on these.

I think your first oscilloscope video might be the video that got me watching your channel and subscribing. Also, making a ring by whistling would be more about phase, but your stereo mics might just be too close together to ever allow to be the required 90 degrees out of phase. The oscilloscope looks like it's stuck in AC mode. I guess it makes sense that a scope intended for dealing with stereo signals would be specifically removing DC bias since it's more interested in differences between the two signals as they'd be relevant to speakers, which DC wouldn't be very relevant at this level of analysis. Though yeah speakers shouldn't ever be receiving a DC biased signal because it could make them build up heat in their coils and burn up. In fact, it likely is the outputs of these devices, because they're specifically going to be removing DC biases to avoid damaging other equipment. You're probably right on the money about why they came out with the executable. A lab electronics oscilloscope with X-Y input would definitely do the job and would certainly be available, but an audio device that won't remove DC would be tough to come by, and likely require modding something existing.
