The return of OSCILLOSCOPE MUSIC with the N-Spheres EP

[@Techmoan]

As pretty much everyone has pointed out, it seems I’m using the wrong kind of scope. If you want to view the ‘ n-spheres EP’ I’d strongly recommend either playing the linked KZbin videos or buying, downloading and running the executable. Only people with the right sort of oscilloscope already 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.

[@Sonnell]

Hey Techmoan, just a small thing: When you play "high res" audio, especially on a laptop, look in to audio settings and set the output sampling frequency and bitrate to the proper higher ones, like 96KHz, or 192kHz, and 24 or 32 bit depth. Otherwise no high res DAC will be in high res mode and will act like a standard one. Perhaps you did, and did not show it to us, I do not know. Otherwise, thanks for the great content! :)

[@KK4CNM]

As @whitslack commented, you will have some capacitive coupling, which would almost certainly cause issues. I am willing to make a custom cable for you if you'd like to try. (free)

[@jgasoft]

The issue with your little portable devices is that they probably have a capacitor in series at the output, therefore filtering out the DC offset required to draw static images at a certain position. That's why you end up with lines with stuff "automatically centered" on the screen. Also, make sure your oscilloscope coupling mode is in DC, not AC, as it will produce the same effect. Cool stuff!

[@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.

[@ijabbott63]

@@MichaelThwaite True, it's not a general purpose oscilloscope, it's a "stereo audio monitor" as it says next to the model number.

[@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.

[@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.

[@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.

[@Timsturbs]

theres no DC in the source audio, only really low AC. if on osc input its just first order high pass filter its easily countered by matching shelving filter. amp + 2 resistors + 2 caps + 2 variable resistors for both channels.

[@Kalvinjj]

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

[@BersekViking]

From an old-timer on oscilloscopes: The problem is not the high frequencies here, but the low ones. The images are centering in the scope because the frequency response does now go low enough. Real oscilloscopes can go down to DC (0 Hz). Audio oscilloscopes don't do, or need, that.

[@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.

[@ChrisPonate]

@@bobblum5973 Its the tech-lovers comfort channel.

[@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.

[@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.

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.

[@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.

[@radry100]

Techmoan on a Thursday?? This is like second christmas.

[@jbaldwin1970]

Is it Thursday? I can never keep up at this time of year

[@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.

[@chrisfratz]

I'm amazed they were able to get the entire EP on a floppy disk in that small of an executable. I wonder if it's just generating the audio in real time instead of relying on pre-recorded files.

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.

[@81oor]

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.

Merry Christmas Mat and Missus!

[@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.

[@martingibbons2488]

Lovely to hear a nod to the c64 and amiga demoscene. Love that stuff!

[@SwitchingPower]

If you google the Tektronix 760A service manual you find on page 145 of the schematic that each input has a pair of 10uF DC blocking capacitors in series with the audio that are the cause of the problem, if you short those out then you should be able to to view the DC part of the wave form if the DAC you are using is also not blocking the DC part of the signal.

[@8bitwiz_]

A DPDT switch would allow switching the DC blocking in and out. Be sure to keep the wires short, of course.

[@TechBench]

Agreed with the issue being the DC blocking caps. However, it is very likely that all the audio gear (including the high-end DACs) also have DC blocking caps in them. You'd have to remove DC blocking caps on _both ends_ in order to get the correct visual representation.

[@lutzweb]

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.

[@LilMissMurder3409]

Oscilloscope demos are among the most inspiring examples of utter, unsung genius.

[@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.

[@bytesabre]

Demosceners are still creating things with limited resources, only now, on modern PCs at least, those limits are artificial and treated like a boxer’s weight classes almost, though are still creating incredible works on old school systems as well.

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.

[@paulstubbs7678]

Ah, your problems are obvious - to me, it's not the top end your missing, but the bottom end, you need a DC link between the DAC and the scope. A proper scope, as opposed to a music visualiser, has a switch on the channel inputs to select DC or AC coupling. However even with that bit sorted, I think you'll find most DAC's intended for audio are going to have an AC coupled output, and any really low stuff, especially DC levels - all important to the sweeping lines - needs a full DC connection. DAC's especially the headphone driving type you had, don't allow DC as that would risk destroying the headphone drives, so anything below say 10Hz is eliminated as no domestic transducer would ever be able to handle it.

[@TzOk]

To see this demo, you'd need to set the oscilloscope to DC XY mode, which none of your *audio monitors* have.

[@Syncopator]

You pretty much need an actual "general purpose" oscilloscope, and that's not what you have. As hundreds of people have pointed out, the scopes you have are AC coupled which is designed to center the displays such that when low frequency audio is the only content of the signals, it'll get moved to the center of the screen and that's causing the bouncing around. A general purpose scope will have an AC/DC switch that will allow you to see proper DC coupled signals. I used to fix scopes for Tektronix, and the one you have is pretty special purpose. If you decide you want to get a more general purpose scope at some point, an important tip-- make sure it supports X/Y display, really budget single-trace scopes might not. Most scopes that support two inputs (dual-trace) will support using them in X/Y mode. It's also possible that the audio output you're producing is AC coupled on the output side in the player you're using, which could also cause this sort of issue. I'm not sure what to do about that, it may be pretty common for audio amplifiers to AC couple their outputs. But, if they have sufficient low frequency response, they still may be able to handle the scope music without bouncing around. More testing there would be required I suppose...

[@dominicbout]

DC offset correction on the audio signal will show up as centering on the scope. It's a matter of finding the component in the chain that's responsible for this.

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.

As others have mentioned, the issue us that audio stages are always AC coupled, so will always drift towards zero. the way to get the true images would be to connect a proper oscilloscope to the output pin of the DAC chip before any other circuitry.

Mind boggling to see & hear this experience 😊

on a scope for engineering you can select AC or DC coupling, the images are moving around because the audio ones are AC coupled. it's good to block DC in audio stuff. AC coupling applies sort of a moving average that keeps the voltage around zero

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.

Love jerobeam, long time fan 😁 if i had money i would buy the ep but im planning to get the digital one somepoint next year🙏 thanks for covering this even tho u had wrong type of machine

Mat is back! And with a new gadget nobody needs but everyone has to have. I can now feed my old Hameg Oszilloskop with messages from outer space. 😅

I am pleased to see that Matt is feeling better!

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.

Looks like the oscilloscope is auto centering which would be handy for everyday use, but not this use. The fact that the music won't really work on most oscilloscopes asks the question 'is it still really oscilloscope music' as it appears to really only work on a computer now. Still epic though, and it's interesting how many extra costs you incurred trying to display something that was sent to you with good intentions!!😊

I used a bunch those of Tek scopes for a long time. Makes me remember my days in linear tape editing.

Yes... DC outputs are not being displayed properly... your 'scope has no AC/DC switch, there is no Trace Position knob, no Centering button... lab and electronics scopes have these. Eight years ago we got Fendersen's first effort and played with it on several different devices... even able to get it to work on a microprocssor kit with OLED shield attached. Big fan of Jerobeam's, this new collab is awesome, thanks for posting.
