I forgot to mention mind, I went down to b&q and spoke into more pipes. And found the solid metal pipes were much better for high end response. Also if it isn't copper the pun doesn't work :D.
If this project proves of interest I'll try other suggested materials. But when I have something in my head I'll be doing it my way. I just like the idea of a mahoosive tall copper spiral in a Perspex box. Lovely. Aluminium could have been good too I never tested it. But copper oohf. Pex and pvc sounded duller to my Ears similar to the hose pipe.
Hey Sam,
Thanks so much for trying and reporting on the other pipe/hose materials. When I saw your video, pex was the first thing that popped into my head for a budget version.
I'm definitely going to try some version of this.
You make really awesome content! Thanks for posting so many experiments / builds!
as long as there’s nobody talking from the pipe when you aren’t talking into it, everything is dandy.
The harder the material, the crisper the sound. Stuff like pvc is softer, and so will absorb and re-emit more of the sound energy, smearing and muffling it slightly. Older ships used to use brass speaking tubes to communicate between compartments this way.
@bhambhole orrr you can try thru big ventilation systems! Place a speaker at the vent in the basement and a mic on the connecting vent two stories up! I bet that would sound cool. Hardest part would be trying to wire a xlr return signal to pipe the sound back to the source for realtime use and synced capture
I would presume that any smooth, hard tube should have a reasonably clean/dry sounding effect, with just delay and no other artefacts introduced.
Aluminium has the problem of work-hardening (all that bending backwards and forwards to get everything aligned) and being more difficult to join (soldering is basically impossible, without exotic filler rods) if you wanted to make joins permanent.
Idea: drain the plumbing in a whole-ass house, put mic in the sink in one end, and go to the other end of the house and put the speaker in a sink or something there. Capture the delays and reverberations of an entire plumbing system.
Maybe a house that's under construction, where they put the plumbing in, but didn't put water through it yet?
Yes and make it a multistory building for some longer echoes.
Put mics in every sink for a multi tap delay
Either that or you need to find a long distance pipeline under construction. th-cam.com/video/p8GcHoSIPDg/w-d-xo.html
I could live a thousand lives and never come up with this concept
And now there’s nothing more in the world I want to see
And this includes taking the spots of Shadow of the Colossus VR and Burtons Batman 3 (with robin williams and billy dee williams as riddler and two face, respectively. There’s a random video explaining it)
In UK plumbing system the lowest point is supposed to be the garden tap, it's even before the kitchen sink, turn water off, open all the taps in house, then open the garden tap, you'll need to leave the taps inside the house full open when turning the water on to avoid airlock/water hammer, then rush round the house turning them all off again.
Should be able to drain a whole 2 story house's plumbing system, excluding the hot water system, in about 10 minutes, maybe a bit more, maybe a bit less.
I’m just glad Sam uses his mad genius for good and not evil.
How do you know he doesn’t do both? I swear I saw the plans for a volcano lair in one of the videos… 😳
@@YippeePlopFork OMG, you could be right!
Well my evil mind is thinking, why not use the delay tubing for distilling moonshine while playing a tune. lol
Problem with this type delay is, that metal add self sound of metal and resonance. Is it not something what has wonderful properties. Only expensive large toy with weird sound.
The first person on TH-cam who didn’t use this much copper for a Tesla coil or whiskey still!
Gotta be at least one guy using it for plumbing.
It is a whiskey still - with a good alibi when the revenue come looking
He's probably using it for distilling moonshine after shooting this video, can't waste all that copper one some delay. lol
Curiosly enough, this type of delay was used (in the form of mercury delay tubes) in early computer memory. It was necessary because at the time, memory was serial.
Oh, we still use delay in computers.
All those bytes have to arrive at the same internal clock tick so quite a lot of effort is spent running lines to have the exact same delay.
However the fastest computer I am aware of used thousands of feet of delay and had a serial arcitecture very simular to early computers.
It was built in the 80's and built entirely from various fiber optic parts to make an electro-optical computer capable of hitting tetrahertz clock speeds.
Of course with much longer input delays, as the machine was hand built the designers used the delay to make fabrication uh.. possible at all.
@@AnonymousAnarchist2 I wasn’t aware of that. I knew early computers used glass u tubes filled with mercury. They had one end covered with a speaker that set up a standing wave that elevated the mercury in the other end. This designated a 1. They were refreshed by looping the 1 back to the speaker to keep the 1 in memory. I have never seen one, even in pictures, but it must have been amazing. And loud. It also drives home how precious memory was at the time. It wasn’t even RAM, it was serial access, which I suppose made it SAM.😂
An idea: suspend a mic over the center of the barrel and two or so speakers at an angle at the bottom for an additional reverb effect.
@@AnonymousAnarchist2 You mean terahertz? The fastest photodiodes ever made have rise times of 36ps. That would only be like 9GHz. Something about your claim doesn't add up.
@@Simple_But_Expensive Here's a video. You can see the memory at 2.54. It's from CSIRAC, the first Australian computer. th-cam.com/video/yxDQSluWaMs/w-d-xo.html&ab_channel=ABCScience
I just discovered your music yesterday. I saw the older version of the hose pipe delay yesterday -- and I bought a 50ft hose pipe today. I'm 64 and I was in my 20s with Depeche Mode and the whole synth scene. I've got a Kawaii K11, an Akai, Tascam 4-track cassette, and a digital effects processor. So, I lack your expertise in analog.
I love your music. You have all the vibe of the 1980s with none of the posing and pretense. You're comfortable being you and it comes across. I'm really digging the IRL analog DIY stuff you're doing. I'm in the USA originally from down south in Georgia. We watch Britbox and not USA since the writing is so good, normal looking people versus models, and the actors know how to act and aren't full of themselves.
When we come to UK someday -- we will schedule it around one of your shows.
Good find LMNC is the best!
If you come over to the UK you could visit the museum, it is a short train journey from Central London.
One interesting thought would be to change the gas/fluid inside the copper pipe to get different delay times and possibly different tambres. Helium would have a speed 3x that of normal air, and something denser like sulphur hexafloride is almost 3x lower. With a suitable interface you could also go to liquids like water, but that would also increase the speed.
The delay in water would be nearly zero in that short of a length. It's probably best to stick to gases to be able to hear any delay at all.
I used to worry about temperature and pressure but got over it.
Dense inert gases would work, but are expensive, e,g xenon. SF6 is probably easier to obtain as it is used by electricity distributors.
As a particle physicist this reminds me of an interesting delay technic we used for our signal processing:
Since some dozen years ago we hadnt enough storage to temporarily store a signal before deciding if it’s worth saving, we used huge barrels gilled with cable. The signal ran through it delayed and then a trigger decided, if the signal is worth keeping.
I knew optics labs had stuff like that, cool that particle labs do too (I mostly studied optics and astronomy)
There was a private stock exchange that did the same thing to discourage high frequency trading. Their data center had several miles of fiber optic cable on a spool in the path to the internet, adding a notable delay to interactions.
Look at a late 50's to 60's Tektronix oscilloscope, you will find a long coil of cable that does exactly that, used to store the signal for hold-off triggering.
About 5 minutes before you posted this video I booked a cross channel ferry ticket for a weekend trip to Kent, looking forward to coming to your museum on Sunday!
They can't say you didn't warn him.
Have fun on your excursion!
@@trashcatlinol update: I went there and it was epic!
Apparently there were full height risers built into BBC Television Centre, housing massive vertical loops of cable that could be tapped into at different points to provide variable video delays. Long after these were replaced with electronic delays, the cable remained in place. An old colleague of mine had a tour of the studios in the early 2000’s and was allowed into the delay towers.
Because creating vertical cable delays and the required building structure to house them is far more space conscious than simply tapping and re-winding it on the same spool on which it was delivered. :|
my 1st analog editing room had a 500m spool of bnc cable sitting in the back of my tape cabinet, resembling our homemade video-delayline.
@@basketballjones6782 Inductive coupling is a thing and would ruin it.
I played in a brass band for years and the cornet player used to do a solo of the post horn gallop with a garden hose and funnel on the end He did the doppler effect spinning the hose above his head.
Interesting idea. 👍👍
For anyone wondering what this would sound like, the late, great Vivian Stanshall plays a brief 'spinning garden hose' solo at the end of the song _I'm the Urban Spaceman_ by the Bonzo Dog Band.
Here's the video evidence: th-cam.com/video/olGXtohOs7c/w-d-xo.htmlfeature=shared&t=132
(well, maybe more of a home brewing style plastic hose, but you get the idea!)
At 1:00 the Sticker on the drum machine that says Binni&Jahn caught my attention immediatelly. I have a 40+ year old guitar amp (Echolette ca 30 manufactured in the GDR) with the same sticker on it. Its from a no longer existing music/instrument store from Straubing in Bavaria. What a neat coincidence
Dude, you are 100% about to get sneaked-up on by a major leagues rabbithole, with that physical delay stuff.
And we are going to love every second of material you chuck our way. ✌️
What's major leagues?
@@LOOKMUMNOCOMPUTER "Top tier", "Very serious", "Not to be triffled with".

@@oasntet I use "major leagues" for anything that has a "vaguely menacing" vibe lol.
Storms. Accidental cut wounds. Headaches. Etc. 😂

Sucked into the void...
Mate, respect for how you listen to the feedback of your audience and then make your own choices from there. I see a strength of character and artistic courage that shows me strengths I need to build on my journey to being a better bloke. Thanks.
The gold chain and the adidas breaker.. like a proper London dj, sir! 😂❤❤❤
Dude looks like mad scientist. Has mad curiosity about boring stuff and make it seem interesting for people that don't have slightest interest in the subject. It really is fun to see people passionate about things they like. The more mad scientists like you the better.
firm handshakes from across the pond. you are an amazing soundsmith. keep up the fun!
oh my god, I had this very same idea of a fully analog, non-electronic audio delay and here you are having made it. Didn't know this had been made in the past.
Now we need a reverberation analog
Sounds so good on the 78! Wonderful you keep experimenting with this
it would be expensive as heck, but i'm imagining a similar apparatus made of glass would be interesting. thickness of glass would have an effect too, i imagine. really cool!
If you're gonna do more of them don't make them equal length. Use powers of two instead, meaning: 1, 2, 4 and 8 units long tubes. Then you can make all combinations of length from 1 to 15 units by selecting different lengths. You could have their ends near each other so a simple connector or plug could be used to make those combinations, but that actually needs some design to make it flexible.
With that approach would it not be a pain to unplug? I'll stick with 8 equidistant
@@LOOKMUMNOCOMPUTER What they're saying is if you put the inputs and outputs of everything next to each other you could make a patch bay of tubes. The patch "cables" might be able to be something flexible without losing too much, needs testing
@@qwitwa I'll stick to the big coil approach as I want it to be literally the sound through the pipe. Not propagation but cheers :)
That works mathematically but not physically. You can't just add time together like that when they all overlap. In other words, you'll just get multiple delays at the same time, not one delay of varying lengths.
How about using trumpet style valves?
This is amazing! reverb / delay from physical devices is always something special to discover.
You can try to change the speed of sound.
Using CO² for example.
Good point
With a coolbox or top loaded freezer you would come and end.
CO² is heavy and would stay inside even when you open the top.
Just don't stick your head in there and try to breathe.
Ah I just posted on this. So it is either a great idea, or we’re both suggesting something really stupid. I suggested using dry ice, as cold CO2 has even slower speed of sound.
@@a41wilde57 As long as it's not pressurized to any significant extent, it'd be safe to make a sealed unit. I'm sure there's some kind of epoxy that could do the job.
SOx or sulphur hexafluoride
I used to manage an irrigation shop so I was surrounded by hoses and pipes. If you wanted to vary the delay time you could set up T pieces at various distances that would allow you to attach other microphones too. I think it would be good practice to install a solenoid just after the T piece. This would allow you to close off the pipe electronically so that the pipe is being shortened to the particular T piece you select. You could then use an Arduino and some relays to control the solenoids.
Next: I snuck into CERN and made the Large Hadron Collider into a delay.
😂😂😂😂
There was an article in a 1950's Popular Electronics or Elementary Electronics magazine using that concept, in the article they used a 50' to 75' garden hose from Sears!
A variation on this would be to put the speaker in the middle and then have a mic on each end of the coils. Pan each mic left and right and it might give the sound some nice stereo width. Very cool project though.
Since each side of that would have the same delay, I'm not sure you'd much variation at the two mics
Great project. Keep the delay ideas coming!
1. Use hose for underfloor heating. It is plastic, but very ridged (maybe even cast it into some concrete?) and comes relatively cheap in rolls of 200m or so (that would give 0.6 seconds of delay)
2. I thought of the possibility for the sound to be reflected of the ends of the pipe, giving multiple delays (al thou much weaker) Maybe add some "sound trap" at the end. A T-junction with the pipe, the mic and some kind of muffler to absorb all the sound. Just like a 50 ohm terminating resistor that you would put on the end of an coax cable
3. Fill the tube with CO2. The speed of sound in Air is 340m/s, but in CO2 it is just 260m/s. That would give you almost 30% more delay for the same pipe.
Sulfur hexafluoride or freon/r11 for sub 150m/s speeds 😅
„Pretend it looks neat“ - I don‘t need to, it looks like something straight out of Jules Verne and it sounds great, that’s all I care about ❤
You could fill the tubes with a gas that has a slower speed of sound to increase the delay without needing to add more pipe! Sulfur hexafluoride should give a roughly 2x boost I think, although you could test it more easily with carbon dioxide first.
Sam's in my walls stealing my pipes!
Thanks!
thankyou
Good ol' Mackie 1640i! One of the bests consumer mixers ever made. After that, Mackie never made anything anywhere near as good.
16 channels, 6 auxes all pre/post selectable, inserts on each channel, direct outs on every channel via firewire or DB25 connectors with pre/post fader selector. A button on every channel to send your DAW's output back to the channel for analog mix down. Individual phantom power on each channel. Just an amazing mixer in every way.
indeed. but doesnt want to work with modern computers, sadly buggy as heck
@@LOOKMUMNOCOMPUTER story of my life. One day the firewire worked, the next day it never worked again 😭😭 I'm currently using the DB25 connectors to go into my Audient interfaces. Great video Sam!
Awesome pre amps, eq and routing options.
It was a shame that in standard form the FireWire cards outputs were before the lovely EQ, and that the FireWire cards were pretty unreliable, but that’s not really a relevant issue nowadays anyway.
@@Jonathan_Doe_ agreed
I've always contemplated making one of these... but I've not been doing enough recording to justify it. I love that Sam just has a go at whatever idea sounds cool and fun.
Make some moonshine while you're at it
hell of a condensing setup with that length of pipe.
@@Nukle0n Especially if you use a condenser mic!
The first hose iteration video got my attention real quick (just last week the algo was so kind). My excitement of seeing this follow up, I immediately subbed, and excited to binge your back catalogue and also see what your future brings!!
You don't know what you're doing sam! ❤
Thank God though!
If everyone actually really knew what they were doing.... nobody would do anything interesting!
The best people never do. 😉
Ohhhhhh man! I never guessed that having the same sound delayed slightly longer in 1 ear vs the other would instantly make me motion sick. What a weird bodily response to what is a really cool sound effect
Love this video. I remember doing an electronic delay line with metres and metres of coax in the past..... not for music but for phase delays on RF / high speed gear. This is an excellent video really loved it.
Omg! This was amazing to see…how such an amazing effect can be created with just a few configurations of pipe…I’m now thinking things…
seriously this is brilliant 😄 I love this creativity. Music is really a sensorial exploration endeavour!
I watched your month or so ago video and now TH-cam recommended me this which I clicked on due to thumbnail/content familiarity and just wanted to say, man the algorithm worked this time.
This is so cool, i am stucked in my habits but your enthusiasm makes me wanna break out of my comfort zone!
Lovely! I saw the thumbnail from this video and it made me think of the antique refrigeration equipment I work on. My Frigidaire from 1926 has a condenser which looks about the same but doesn't sound nearly as good!
I always worked with plaster.. I always wanted to make stackable plates with a spiral cavity through it for exactly this purpose. Nice work!!
So clever! You could even fill different hoses/pipes with dissimilar liquids, foam, etc.
This is crazy. I can imagine lots of uses for this 'technology'.
I saw a video of an EE who wanted to time voltage over distance. Like your tubing coils, he used wire, in a zig-zag pattern, attached to a 4 ft. x 4 ft. frame. In the end, this gave him quite a distance of wire and allowed him to time the duration of current moving through the long length of wire, from one end to the other, on an oscilloscope.
Delightful process of exploring! Curiosity is the primary sign of intelligence in my experience. You Sir, are brilliant. Thank you for sharing!
This really reminded me of some of the sounds of Blue Man Group when we went to see them. The delays were beautiful, and I have a feeling they might have been inspired a little if they hadn't already had their pipes they used to do music already.
Very cool. All kinds of possibilities. I love the dual "taps" you implemented!
In the beginning of your video i saw on your work bench the little ocilliscope 310. I had the very same scope when I was younger.
I had to give it up when i moved.
It was built so amazing inside. I hope you enjoy it.
So nice to see somebody with ambition running this experiment. Shure SM-11s are handy for this type of thing, btw, I have about a half-dozen because I have lots of strange stuff going on.
Love that I can't even tell the difference. Obviously I can tell the difference when the feedback is added though.
Got a huge shiver at 10:15! reminds me of old sci-fi UFO sounds
This is delightful. Gods I wanted to build a Cooper Time Cube several years ago but I just never got to it for a variety of reasons like microphone money and such.
We’ve come a long way since having reverb on my 1960’s HiFi. A simple spring about 3 feet or so long, run back and forth inside the cabinet a few times. The signal to the speakers would go through that simple conductor. For that “concert hall sound” on all your LP’s
Dreams can come true. Interesting. I nearly went down this rabbit hole of goodness. Beautiful execution.
You're probably one of the best inventors out there.
Just AMAZING project dear Sam not to forget Hainbach too, it sounds wicked good, and cool character, Thanks n cheers
Really one of the mad inventors of our time 😂 this seems could go lots of places
idea: put a speaker on each end and listen to the center mic, you might get some interesting stuff with interference.
in theory, if they have reversed polarities you should have no sound in the mic.
an interesting thing, once you have 2 of those, might be to have one regular delay and the other setup like this, with one speaker getting the delay and the other getting no delay.
Someone suggested getting more delay by filling tube with Carbon Dioxide which transmits sound slower than regular air. That should be easy to get as welding supplies, just need to make sure the tube is sealed more or less airtight so it doesn't leak out and affect how much delay you have. Doesn't have to hold pressure, just not let air circulate in and out.
I would also suggest for even longer delays you should be able to make a second coil stack that's wider than the inner one to keep the height under control while also adding more tube. Presumably you'd like to keep the tube stack small enough to fit through doors :)
I'm really a fan of just using whatever is around for audio amplification and for a couple of years now have just been using two and a half styrofoam coffee cups to tilt my tablet on and it works brilliantly
I remember when Eventide came out with the 1st gen Harmonizer I was fooling around in the studio with just some 1k tone and got some crazy sounds coming out of it between the pitch shift and the delays.
YAY! I have wondered about building a delay with corrugated pipe, but now I learn that would not work. I say put it in a box and fill it with foam to stop the feedback whistle? Oh, you did mention isolation at the end ok. PERFECT! xD
Professor voice when explaining the bracket, cracked me up😂😂🤣
I liked that. Something I have long wanted to try but never got around to is cutting a bunch of pipes to resonate at all of the tones and overtones within the human vocal range. I'm cheap so I'd probably use that black semi-flexible plastic pipe often used for irrigation. I was thinking of packing the pipes into hexagonal bundles and then packing the bundles together like a see-through honeycomb with one end of the pipes in the sound source chamber and the other ends of all the pipes in the destination chamber. If nothing else it keeps the footprint compact. From there there is the cheap way--one mic in the destination chamber. Or the expensive electronics graybeard way of one microphone per pipe which I'd at least experiment with on a small scale to see if it is worth bothering with. I think with a bunch of individual microphones you might be able to very finely shape the sound of the voice by adjusting their gains. I like to think it would potentially sound neat but maybe it would sound like crap, I really don't know and can imagine ways it could go either way.
Great sound, I love the feedback breaking up into distortion.
Just remember that pipe diameter will attenuate low frequency sounds. Larger pipe = more bass.
Awesome you made an analog version of the sound of a low cost rack digital delay from the early 80s!
But.... way cooler looking so you definitely got an eye for the art!
You probably thought about this but maybe not so I’m gonna post it anyway. If you speed up the audio that’s going into the tube, record that and slow it down, the pipe will sound bigger and longer. If you speed it up 2x, it becomes an octave higher and twice as fast, but it will take the same time to travel from one end to the other end of the pipe. Record that and slow it down again and you’ve got twice the delaytime.
Having done this sort of stuff digitally before, I love that you have almost no chance of getting the two pipe lengths exactly equal... which gets rid of all that "boring" digital precision.
OOOOH THIS TICKLES MY BRAIN I LOVE THIS
Hey Sam,
Really cool experiment! I'm curious about how the original patent uses hemolts resonators to quell the peak resonance of the pipe and also damping and either end.
You may be onto something really cool here!
you are a mad talented crazy genius. Love you bro 💕💕. Me pops was a plumber (read in yourkshire accent) so grew up around copper pipes - we used the pipes to make barrels for spear guns not music. If I was a teen - this would be my new life direction. So playing with wild dinosaurs, koalas and parrots is what I do today..... keep up the groovey things mate.
When we were young, we have something similar to play with.
Take a large can like six inches in diameter, about eight inches tall.
Pop out the lid and cut away the bottom to make it into a cylinder.
Next take a balloon, cut away the neck side of the balloon,
wrap this elastic sheet to the opening of the cylinder.
Now you get a bucket like structure and it looks like a drum.
When you talk into the bucket, it has some interesting sound
effect.
It is a simple inexpensive toy.
love your oldscool delayline. boah- copper has a hefty price tag. adapting a stack of assorted iron tubing (maybe from a scrap metal yard?) between your copper windings would be a cheap expansion kit? divert some bucks for one or two cans of soft or/and sprayfoam-insulation between the copper windings and the environment to prevent overtalk and also u get bits of dryiness in your sounddesign. the clamps are resonators between the windings, a combined TPU print does the trick.
Looks/sounds awesome! So stoked you spotted the comments about coiled up copper pipe being a thing.
Be interesting to see how it’d sound filled up with water, with a contact mic/s on it, but then it’d be difficult to work out how to vibrate it.
You could sell off excess creativity and still have a ton left. I can't think of a single youtube channel that's shown so many very different from each other projects.
was planning on using a roll of soft copper to make one myself, after watching your last video!!
First thought is that this is a combination of a short spring reverb (sound transmission in the copper itself) and an acoustic reverb (sound transmission through the air in the tube). Could test by dampening the coils (maybe wrap a blanket around touching all the coils). And test if there is any sound difference. Keep up the great work. Fun to watch. I also enjoyed the concert footage. Looks like you have a blast up there.
There is no discernible sound exchange through the mounts. As you can hear when there is no feedback
I fucking love whenever a LMNC video drops. I just know it’s going to be something crazy fun!
❤️❤️❤️
love your collaborations with hainbach! hope you guys do more, you guys are very interesting together.
Give this man an award, I wouldn't be able to tell which one though.
You, sir, are an Insane Maniac. And i absolutely love that I stumbled over your channel! 😍
Love it! You and Heinbach are faaaantastic! One word: “helium”
Fun experiment! Glad you did it before I did. That's a lot of money and time for such a limited use effect.
It's cool how the copper has some intense overtones that the normal gardenhose didn't have. Really nice to hear these different types of tembres
The garden hose did have the same we just didn't let it feedback as much
@@LOOKMUMNOCOMPUTER oh alright very fair then!
I was beginning to think we'd have Sam trying _n_ different materials, along the lines of the different speakers - a.k.a. _diffuseurs_ - which were made for the Ondes Martenot, the keyboard immortalised by Barry Gray in his scores for Gerry Anderson's various puppet series. 😉
en.wikipedia.org/wiki/Ondes_Martenot
analog solutions like this are always a fun engineering puzzle
i have to say, that copper loop at around 8:10 looks really neat
If you are adding a mid point, you're creating a half length delay, and you could bang the output back into the input electronically to get kinda that effect, so perhaps tapping at 1/3 the length to give you more timing options (1/3,2/3 and full)
Awesome project!
Two things that came to mind: you used 3d-printed pieces to stiffen the whole thing to only get the delay-effect. Would going the other way work too and use the mechanical flexibility of the tubes to get something like a spring-reverb? Probably, you can't excite the whole thing with a small speaker in that case.
When adding feedback another thing came to mind: old damaged brass-instruments are quite easy to come by. The conical bore should give some interesting results....
For longer delay times, you'd have to take a tuba, though. And those are quite expensive, even completely damaged.
While the theoretical delay can certainly be extended, the trouble is that the tube tends to erode bandwidth by being an imperfect reflecting surface. And of course, we have no idea about any standing waves created within. It would, however, benefit greatly from some anticipatory tone-shaping in the send signal, as well as in the receive signal.
But, since you're so enamored of unusual sonic applications of materials, I encourage you to look into "distributed mass loudspeakers". These are loudspeakers employing light membrane-like materials (foam housing insulation is an excellent one) and audio "exciters". I tried some experiments at home, and I am amazed by just how good even a cheap version can sound. You're just the guy to fritter around with this and come up with 150cm x 150cm loudspeaker, with multiple strategically-placed exciters delivering a HUGE sound, while they hang from a frame.
Pipe delay makes that old Roland CR-78 sound amazing. 👍
😆You always get to the bottom of it, do you? 😆
Back in the days, a friend did some recordings in the basement of the family house. We used the heating's fuel tanks as echo. We used the staircase as echo (much to neighbour's dismay), we used a metal locker as delay.
So much fun. And here I am, years and loads of PT2399 later, here I am consider to visit Obi... 😆
Maybe am not the first one: the high frequency osszillation results from mechanical waves transferred inside the copper walls. The transfer speed ist mucher higher compared to the acustic waves in the gas. Simply isolate the mic and speaker mechanically from the copper tube. You could use a few inch of rubber hose or similar.
It's not loud enough inside the pipes for that to happen
@@LOOKMUMNOCOMPUTER my idea was the movement of the speaker body couples into the copper pipe.
@@nasszelle534 indeed but the volume is as low as headphones. the result is minimal mechanical vibration
Weld the ends of the coils into a big loop. Use y-splitters to tap into the pipe, use angles at your advantage. You need at least two taps, one for the speaker, one for the mic. Add a valve between the last mic and the speaker, to control "bleed". The sound should go round and round... But with valve it can be returned back to "good old coil delay" configuration... Also, the ends can go into a chamber. If that chamber has tons of baffles, it can become a reverb unit.
Ok, i got it, wrap copper pipe around an oil drum, connect the ends to it, put a mic into the oil drum and tap a speaker to the coil. The coil should touch the oil drum to get most out of the sound energy and diffuse the hell out of it..
When I was 16 and just getting into Electronics and had the opportunity to Repair a Guitar Amplifier. (My First at that time) I was Amazed that the Reverberation effect was done simply with springs.. (So.. Garden Hose Makes sense) .. K.I.S.S. (Method) .. Do what Works.. (But.. It's not exactly something you can stick in your Pocket). The added bonus with that large Copper Coil.. You can make some Moonshine.. After the experiment. 😊 ..
After electro-mechanical spring reverb... Acoustical delay !!!
Great job, great idea dude! really! 😄
Since you're working with plumbing fittings it might be interesting to introduce a ball value or two to create reflections in the wave (between the first and second mic?). Fully open they'd likely be near invisible, but partly closed and you may get reflections like actual reverberation.
