[@AquarianSoulTimeTraveler]

Would be very interesting to cast the whole thing in concrete with the hoses and all to make it more solid and see how different it sounds

[@AquarianSoulTimeTraveler]

Imagine you get more volume from a concrete cast because it can't vibrate as much forcing the sound to go down the pipe instead

Can you call the manager there's two weird guys lurking about up the plumbing aisle, they're making strange noises and blowing in the hosepipes! "Excuse me lads, can I help you?" "We're fine, we are going to be recording a song called Pipe Dreams."

[@Felttipfuzzywuzzyflyguy]

😂

[@jzero4813]

6:38 : 89ms is just around exactly what you would expect -> 30m hose divided by (speed of sound) 343m/sec = 0.0874sec, or 87.4ms. This will change depending on temperature but the hose is probably a bit longer than 30m (so they don't go to prison for false advertising) and that's likely where the other 1.6ms came from. 89ms is 1/16th notes at 168bpm.

[@phluid61]

And to take it a step further, if you want 30 ms specifically, 343 m/s × 0.03 s = 10.29 m

[@TeTe76VTheChiken]

We can estimate the temperature of the studio in kelvin with (30/(0.089*20))^2, we do -273,15 to the result ans we get about 11 °C

[@TeTe76VTheChiken]

It's not precise because if we take 88 ms instead of 89, we obtained 17 °C

[@cyberyogicowindler2448]

Together with mouthpiece and a traffic cone it makes an Alpschlauch (portable wannabe alphorn).

[@axel_is_gaming]

You need to get a hose that is made of plastic, one of those pexal hoses, that also has aluminium insertion. This hose is rubbery, it will dampen the sound. 100% procent will sound a lot beter with a pexal hose.

[@Hainbach]

Cool tip!

[@TDOBrandano]

the black PVC pipes for drip irrigation might work well for this, and should be fairly cheap. the box will have to be bigger though.

[@confuseatronica]

theres so many different hoses, you could just have a collection of different ones to swap in

[@kschleic9053]

@@TDOBrandano Heat it up and you could pull it into a tighter coil than it ships in...

[@pauljs75]

I'd bet wall thickness affects the sound too. So it could be more "echo-y" with something thin-walled and made of a relatively stiff material.

[@Murgoh]

Back in the 70's when I was a child my grandfather had a huge coil (maybe some 100 meters) of 1" polyethene water pipe at the summer place. I would always be shouting and speking into the pipe and listening to the echo coming through the other end.

[@MrJonBertsch]

I work in a plumbing warehouse and I’m surrounded by coils of pipe in tons of sizes and materials. Wonder what a 100 foot coil of 2” copper would sound like? Or maybe a 500 feet roll of gas pipe?? Gonna have to try this out on a few 😊

[@alexandremargat2350]

"Next week, we'll learn how to make a looper with a coffee grinder. Stay tuned!"

IIRC, the og. Time Cube had 2 hoses of 14ft. and 16ft. respectively, which gave it 14 and 16 ms of delay. For practical purposes, you can calculate delay times with 1ft.=1ms or 1meter=3 ms.

[@kensmith5694]

If I was designing a thing like it, I would use 13ft and 16ft. The lengths share no divisors. And the difference shares no divisor. This way when you loop it back for feedback to make a sustained echo, you get the signal repeated at times of: 13ms 16ms 13ms + 13ms 13ms + 16ms 16ms + 16ms 13ms + 13ms + 13mS .... etc ... The list goes on with no two sums equal until you get out to 2.08 seconds.

[@GizzyDillespee]

Ideally you'd want to tune it to the root or key of the track. As far as L-R detune, I'd cut 1 side slightly longer than the ideal length, and the other slightly shorter. IDK the ideal offset, so that it separates, but doesn't quite chorus. I guess trial and error is difficult when you have to cut more material, from one side or the other, for each new trial. You could figure it out the best sounding detune amount digitally, and then do the math to find the correct difference in hose length, for that detune amount.

[@nigelworwood8530]

Back in the early 60s I had an earthing spring from a TV CRT. At one end was a loud speaker attached by 3 x threads through the cone at the other end was a record player cartridge. This used a stylus that was held in by a screw. The stylus was replaced by a sewing needle and again thread was used to attach it to the spring. This gave a beautiful sound to the input. Although my mother didn't agree! Also you could tap the spring and produce noises that would considered to be in the Star Wars canon.

[@cyberyogicowindler2448]

Sproing reverbs... Also don't forget the non-electronic Echo Mike soundtoy.

[@HyraxAttax]

DIY talk boxes use speaker horn drivers for the speaker, which are designed to pump sound out of a small hole that you can just shove a tube into.

[@theonlywoody2shoes]

Speed of sound in air 330 metres per second. 30m of hose pipe = 30/330 = 0.909 seconds, or 90.9mS, so you measurement in the video at 6:36 of 89mS is pretty spot on. I love old school solutions that are sadly just digitised these days. I’ve been aware of spring reverb and delay units, but pipe delays were not something I’d come across before, so thanks for sharing.

[@kaitlyn__L]

I saw another cool video about a pipe delay that used larger-diameter rigid PVC pipes, and could disconnect sections to reduce the delay time. It sounded pretty good!

[@actodesco]

In the 60s, reverb was something everyone seemed to want, even in our cars. They made reverb units especially for car. These used the spring units that were originally designed for Hammond organs, only smaller. When you went over a bump in the road, ....twang, twang, twang. Anyway, Popular Science or Mechanics, I think Mechanics, did a thing where they used a garden hose, a funnel, speaker and microphone, similar to the one you built in the video. I always wanted to build on myself, however, I never seemed to have the time or money at that time.

[@fissionchips8840]

As a Canadian, all I can say is: "What a pair of hosers, eh?"😂 When I was a kid, we used to fool around with garden hoses like this all the time, talking to each other . You had to be careful that your friend didn't get cute and attach his end to the outside water tap!

[@entropybentwhistle]

Came here looking for who made the Bob & Doug reference first. We’ll have to send them emergency toques and donuts since there was a serious lack of such in the vid.

[@keeperofthegood]

Air/Water Tube delays are watery cool :) Like trying to sing in an indoor pool room. Ive often wondered about flat springs as delay (laser cut sheet metal to a spiral, place a driver element at the center, and pick up points along the spiral arc) or using the spongy action of a column of magnets in a tube, South to South then North to North, as there is a period of absorption time before each repelling magnet moves next, drive one end and pick up on the other :)

[@marksieczko7766]

What a great idea. Could even be expanded on by using electromagnets to damp/excite the spring rhythmically.

[@industrialmonk]

Love it reminds me of old CRT TVs that had a time delay component that was just a length of wire proper old school.

[@McSlobo]

Well, weirdly enough, in modern computing devices circuit board's wire lengths have tight tolerances, and occasionally some extra curves are made to have them in sync. Especially visible in devices like high frequency oscilloscopes.

[@cyberyogicowindler2448]

​@@McSlobo The traces for RGB components in high quality graphics cards often had additional curves to make them exactly same length to avoid delay.

[@marksieczko7766]

With the dry/wet ratio set right it's blimmin' great.Quite inspiring really.

[@hoboroadie4623]

Much more scientific than when I tried this out. Just like a hoboroadie, I first got Butyl Rubber hose, which is the most expensive, and also the most effective at attenuation of the SPL. Twenty feet to deadness. Hard pipe is where it is at. When my Uncle rebuilt his house in Berkeley, he installed speaking tubes from the kitchen to the library and to the kid's playroom. Like the tubes from the Bridge to the Engine Room. (Full speed ahead!) One of my favorite mics is the SM-11, which is essentially a free-ranging Cartridge from a SM-57 or 58 mic, Omnidirectional so it doesn't do the proximity thing and you can drop it into spots for a sample of the sound.

[@Jonathan_Doe_]

You can buy 25M coils of 15mm copper pipe… Not cheap, but it’d probably have more high end to it than the rubbery plastic.

[@JH-lo9ut]

Yeah, the rubber (soft plastic probably absorbs a bit of sound. In the picture of that original pipe delay it looks like they might have used pressurized air-hose, wich makes sence, since it is pretty rigid and doesn't expand.

[@PhilR0gers]

Never seen coils of 15mm, but you can get coils of 10mm and 8mm.

[@Wagoo]

yeah I've wondered about these too.. but in the case of tight coils of copper.. perhaps you need to insulate each loop of the coil from the next.. to avoid metal->metal transmission of the signal "jumping ahead" through the system. May or may not be a bad thing, soundwise, though

[@ErickvdK]

PE hose for drinkingwater or floorheating is probably cheaper.😊

[@musiqtee]

I did sessions in Stockholm’s long defunct Decibel Studio in 1986. They had two pipe-delays in full operation - I used them for mainstream synth pop… What would I know, I was 20 ½. _“What do you mean ‘retro’ 38 years into the future…?”_ 😂

[@EarthWalkerOne]

Awesome. I had a lot of fun playing with stuff like this a while back. My favorite was a using the speaker and mic from an 60s telephone with bamboo and a really thin-walled plastic tube.

[@hobbified]

Just a couple weeks ago I was at the Norwegian Museum of Science and Technology (Norsk Teknisk Museum) and they had this as an exhibit, only without the electronics. Just a big length of pipe coiled up on the wall, with a couple funnels arranged so that you could put your ear next to one while you yelled into the other. It was about a quarter second of delay, so maybe 100m of pipe.

[@bylescx]

that green flexible conduit was corrugated? i wonder how the turbulance might affect your delay. much wider diamater and less rubbery too, maybe less vibration would be absorbed too? .. dunno 😊

[@geraldfriend256]

I only know this much from homemade wind instruments.: corrugated hose gives more growl.

[@ervinpoljak8332]

The guys at OBi were like wtf dudes, when they saw you blowing these pipes :)))) ❤

[@donm1547]

Ok, guys great video. Reminds me of 40 years ago and a Studio that a friend was building had an array of 3" in pipes up in the ceiling all of different lengths, probably 5 different lengths, ranging from 10 ft to 30 ft and each one equated to a different delay value, the delay calculation is approximately 1 millisecond per foot of pipe, you can use one speaker to Source all the pipes at once and One mic in each one of the ends of the tubes to record five different tracks of different delay values, and select the delay that works the best, also, when you use a larger pipe like a 3-inch irrigation pipe you don't have as much of the muffling as you experienced with the hose tube , try it and I think you'll be amazed!

[@kensmith5694]

Interesting! A huge number of years ago I helped someone with the design of a quite different delay but a few of these things may still apply 1) If you equalize on the way into the speaker you can get the frequency response back closer to flat. 2) Reversing the polarity of the drive to the speaker (input transducer) in one case helped to defeat oscillation 3) This one is a bit complex. If you bring the output transducer back to your mixer to do feedback you can get a long echo. If however, you combine with the singer and then compress before feeding it into the speaker, each new sound from the singer tends to replace the sound that is echoing about. A bit of a volume expand on the output of the total system before you go to recording makes the fading echo drop away faster after a bit of time.

[@leopiipponen7693]

The hose delay could also make multiple analog signals of the hose mixer into one , Y-Type Tee :)

[@PaulSpades]

A mechanical mixer. Needs some valves for each channel, but I like it!

[@guitfidle]

You can also do this with headphone elements, both as speaker and microphone. My daughter gets these cheap on ear headphones, the cord wears out really quick, so I save the elements for experiments like this. You can even get broken ones from a flea market or second hand store- usually the cable is the issue, and the elements work fine (usually).

[@guitfidle]

Man, I gotta try this right away.... pretty sure I have a scrap hose to use, I have several of the headphone elements, plenty of cabling.... got a Field Kit, has 4 inputs, could do 4 different lengths....

[@feltusfeicit]

Seriously, I've had a length of 10mm copper pipe wrapped around a big cardboard tube for over a decade, specifically for this purpose (and without knowing about the legacy equipment). My plan was to have the coil, which is about 80cm long, with several t-junction 'taps' with mics down the length for different amounts of delay. I think I bought the pipe from the scratch and dent shelf at a plumbing supply shop in Edinburgh after seeing a doc on the basement reverb that Abbey Road used to have.

[@theokidokis]

You can use the speakered tube as a talkbox also!

[@Richardincancale]

Perfect timing - I was just thinking about making an analogue reverb last night! You could put some diverter valves in the tube to vary the delay!

[@Stereomoo]

Maybe you could adapt a slide whistle to tune its resonant frequencies, really dial it in to the key you're playing (or just wiggle it to get weird delay effects)

[@robomatrix4582]

this is actually some of the most entertaining content online, next to what rob scallion and andy huang do. their all wildly talented.

[@Wagoo]

I love this kind of shit. I've often wondered if you could put multiple mics at tap points down the length of the tube, or if that'd ruin the signal. It sounds pretty filtered anyway, though.. so just need to give it a go really

[@Alacritous]

I've been wanting to make a Talk Box and you putting that speaker on a funnel is the last piece of the puzzle. Cheers.

[@DjDoggDad]

Putting a hose on a speaker is the only piece of that puzzle 🤣 you can also just put a funnel and hose on any old practice amp for your own talk box

[@gorignac7487]

Some ski resorts in the USA use a hose between the top and bottom of the lifts for communication. The harder the material of the hose, the better it keeps the sound without dampening it.

[@cyberyogicowindler2448]

These things were also used for communication from bridge to the engine room in steam ships.

[@lemn8]

I was wondering if you could 3D print a cube with a complex tunneling system inside. The material like PLA is much harder so it wouldnt muffle the "highs" as much like the rubber hose.

[@GistOfItMedia]

unbelievably righteous commitment to the craft

[@frankl5963]

I wonder if some insulation between each loop of the hose would keep vibrations from traveling through the walls instead of just through the air in the hose.

[@jzero4813]

Wonder not - it would. Significantly. In rubber the speed of sound is about 60m/sec, so across a 0.2m wide bundle that's approximately a 3.3ms delay. Around the whole 30m it's a half second delay, but the damping would be so strong almost no power would be left in the wall vibration at the other end. It's a really good idea.

[@tomholroyd7519]

I put my PhD advisor in headphones connected through a digital delay to the mic in his hand. Set to ~1 second delay. He said, "It doesn't seem seem to be doing anything." I said, "You said 'seem' twice." Delayed Audio Feedback really messes with your speech brains at long delays. OTOH at 30~40 ms you are getting into beta/gamma Hz range which is a very important frequency in the brain; those sorts of frequencies cause ENTRAINMENT of neurons, which does strange things. Neurons are little non-linear oscillators (not computers) and they will easily couple at 40 Hz. You can even see BEAT frequencies in the BRAIN data if you add two close sinusoids together for the auditory stimulus. (IDK when the last time you listened to a pure sine wave was, lol ...)

[@PhilR0gers]

I can't believe how good this sounds.

[@audhen1]

Always happy seeing you both :D

[@PhilLesh69]

I took a sound reinforcement and studio engineering course at the Loudon campus of Northern Virginia community college about thirty years ago. They had a gigantic plat reverb in the classroom. Everyone thought it was a giant rolling chalkboard because it was mixed in with that sort of stuff along a back wall. It was a big rectangular frame with a wooden enclosure and a four foot by eight foot quarter inch steel plate suspended from the top on springs and stabilized by sound isolating rubber mounts along the other sides, and it had a transducer attached to the top left corner and a pickup on the bottom right. I also went to see John Scofield about twenty years ago. He has a moog synthesizer or maybe it's called something else. It was a keyboard/organ powered by a giant spinning wheel that pumped air through the pipes. It had a separate box for the "air powered amplifier".

[@PhilLesh69]

Plat = plate.

[@TheDistur]

That is so cool. The things people think of!

You might want to look into the Xophonic, made by Radio Craftsmen Inc. in the 1950s. A similar idea, but using metal pipe and marketed at home hi-fi enthusiasts of the time.

[@BobBrandon]

Back in the 60s and 70s, there were some radio stations that used similar hoses in the audio chain to add echo to their announcer's voices.

[@sgctactics]

Copper tubing comes in coils, I bet it could provide more of a high/band pass effect. Mix that with the hose one and I bet you could get all sorts of sonic range. Voltage controlled tubing delay/filter? I think VCTDF should be a common acronym

[@hoboroadie4623]

sgctactics, exactly!

[@matthewday7565]

Maybe you could apply an ascending EQ to the drive, to balance the muffling

[@hoboroadie4623]

Harder pipe. Brass was used in old ships and submarines. Or embrace the tone- I just scored a Western Electric Carbon Cartridge mic to capture my Talkbox tone. (Two hoses fed from a Stereo Leslie Emulator is the latest trick)

[@gorak9000]

Need to calibrate by running white noise through it and looking at the resulting spectrum. Then pre-compensate with an EQ that's opposite the spectral response from the hose. Might need to notch out the resonant frequency as well - you can hear some feedback forming towards the very end of the video.

[@slooberslodge]

I've got a Urei time cube, it works best feeding one pipe into the other and then feeding back the whole thing using a mixer. The feedback has quite a different quality than any other delay, its not amazing but pretty cool, I like it a lot. BUT i read an interview with the original designer and he said Urei messed up his design as they used garden hose but he originally used Copper pipe ! One would think yes Copper or some other metalic pipe should sound better as hose pipe is pretty dead and boring, I never got around to trying it though...i was hoping u2 were going to do it!

[@billybob915]

During the quadraphonic boom in the 70s there was an article, maybe popular electronics, had a DIY that used a 3" speaker stuck into a funnel, 25ft of garden hose and a mic at the other end. Times two, sending each to the opposite rear channel. Poor man's ambient, or synthethized quadraphonic.

[@ssmedia]

Probably a good thing you left it with Hainbach.. Imagine trying to explain that to airport security 😂

[@Oglokoog]

definitely a bomb

[@ferrifet7267]

Thats really quite effective, might have to build one! ❤

[@CensoredByYouTube.]

The speed of sound is around 342.6m/sec, or roughly 2.92ms per meter. If the original unit had a delay time of 30ms, you would have wanted a ~10m hose, not 30. Also, a more rigid-walled plastic tubing (PEX, maybe?) would prevent dampening the sound to the degree that a softer garden hose would. Some have suggested copper, but that has its own resonance if you're trying to keep the delayed sound as clean as possible.

[@NathanSeeley]

If you put the ends of the hose out the sides of the box, you can fill it with expanding foam to isolate it better

[@kingpishful]

I've heard of Sylvia Massey doing this on drum kits with a hose. You guys would probably like her book. There is stuff on KZbin with her and the Melvins where she uses an old bulb(also a pickle) to make distortion too. KZbin Melvins Pickle Solo

I found a video on here with an engineer digging a well. It's about a foot wide and a few hundred feet deep. Reminds me of the time cube. It made the most uniquely pleasant sounding delay and it's my dream to have one for the home studio!

[@sharptrickster]

I wonder what a "physical scanner vibrato" would sound like. Imagine instead of having a rotary contraption tapping signals from different points on the resistor-inductor ladder for different phases, you had the hose drilled with electrets every ~1 or 2 meters for example, and a sequencer switching their output for modulating the delay times? In my mind, the hose would look like a "flute" drilled at the diameter of the electret, which would be placed and covered in epoxy so the sound would continue travelling until the end. Not covering the end and letting the sound go through the other end should give a more "open" sound too, maybe? (open ended) I love your videos, they are really inspiring. Keep doing your experiments and sharing with us please. Thanks o/

Always loving the Hainbach/LMNC collabs! A synthesis of Law and Chaos, you guys are hella creative. This reminds me of the magnetostrictive torsional delay line memory used in Soviet Iskra 111 calculators. As the name suggests, that also conveys mechanical pulses through a long physical object.

"basically, a long corridor in a box" I love this, real ingenuity creating a great effect. I also enjoyed your clever testing method in the hardware store (I'd have been the idiot who bought three different lengths to try out at home). Best of luck with your vinyl release! (By the way, ignoring other effects, each 10 metres should produce ~30ms delay, based solely on the speed of sound in air. The hose wall itself might also propagate significant sound and that would travel much faster, maybe a 3ms delay per 10 metres, depending on material - check the isolated recording for its own echo).

Love real-world echos, and reverbs. Now I want to try a "Y" shaped hose, with one side of the "Y" reaching just a little further than the other, with two mics. A quickly doubled echo returning....

Crazy! Literally 2 days ago I thought of this idea and wondered whether it would work! I was thinking of it in the context of hammering tuned PVC pipes but still. 😄

[@TVPiles]

The first time I saw something like that was in Popular Electronics some time in the 60s, now they tried to make a pseudo Quadro sound and had 2 boxes with tubes.

[@xtieburn]

So, 1/343*length of hose in metres = delay in seconds. Or about 0.087s for a 30m hose, or 87ms. (50m would be 0.146s)

Loved this video

[@davidpotsdam]

Sounds Way GOOD

Call the psych ward, there are some guys in the garden accessories aisle needing help. Also get someone to announce on PA, that garden centre is being closed down due to maintenance...

[@ronhoffman1008]

A 3.35 meter hose will give you a 10mS delay. By feeding the output back into the input. you can adjust the decay and create perfect reverb effects.

[@LOOKMUMNOCOMPUTER]

Yep it'll make a tuneable whine. Watch this space as making a multitap ones with feedback for reverbbb oooooh

[@cyberyogicowindler2448]

@@LOOKMUMNOCOMPUTER Use flute physics formulas to get certain overtones.

[@LeslieDugger]

Get 2 different hose lengths and attach a y valve . You now have a delay time switcher. I’d probably also use a cooler as the enclosure for good insulation EDIT: Oops. Wrote this before seeing the end where you me too 2 hose lengths

[@scottvogel8477]

I would gladly watch a series of you two just messing around with music ideas.

[@ambiention]

You can also use it as a funky fx microphone either coiled up, or unrolled around the room. You could just block one end, or better yet with the speaker like a mic and get a stereo signal

[@timonsku]

Cool stuff! Maybe give hoses for pressurized air a try, the material used is much stiffer than the rubber in garden hoses which should muffle it less and they are equally cheap if not cheaper!

[@AM2PMReviews]

Nice homemade delay….Thank you….nice homemade delay….Thank yooouuuu

[@Ziraya0]

If you could get access to a roll of metal tube, the hard walls should reflect higher frequencies better, which could be an interesting partner for this one. The metal walls could also conduct low frequencies perpendicularly across the coil so there could be a stronger degree of spectral separation. I say access, the main rolled metal tube I know about is copper and that gets very expensive quickly, somebody can probably calculate the effect of frequency response on diameter, maybe brakeline or refrigerant line will work

[@meistudiony]

Cooper time cube was an ingenious and awesome bit of kit! If im not mistaken the had 2 hoses so you could get 2 different delay times. This is awesome! Love seeing creative solutions like this. Almost sounds like a reverb with the feedback. LOL i sent my comment before the video was over, and yeah you guys mentioned that. So cool! Congrats!

[@cyberyogicowindler2448]

Add an Y junction between 2 hoses for mixing the outputs. I guess that plenty of brass instrument principles may be repurposed for this.

[@AnonymousAnarchist2]

Oh I am certianly going to mess around with this.
