You can now get both of the EP's on vinyl!!! there is a bandcamp vinyl campaign link above!!! PEACE
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
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
Unfortunately, postage to the UK appears to be more expensive than the record?
@@Nervejam yeah its mad int it :(
Sam when you gonna make a rotory subwoofer?
Sir there's people blowing in the hoses... again
I seriously don't think that is a regular thing :)
Though, with the funnel too, they definitely thought they were gonna be cooking up some drugs or something :D
I do that all the time.
@@kassemir You have no idea how often stuff like this happens. Also with wastewater pipes
Hey, help me here!
What is your best hose for delay-based applications?
eh, it was only the 4th weirdest thing the store employees saw that day
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.
And to take it a step further, if you want 30 ms specifically, 343 m/s × 0.03 s = 10.29 m
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
It's not precise because if we take 88 ms instead of 89, we obtained 17 °C
@@TeTe76VTheChiken Yes, and there is uncertainty on the length. Hardware store labels are not exactly NIST quality measures.
You and Hainbach make a great Adam Savage / Jamie Hyneman-type duo
Synth-Busters!!!!!
@@B-NiceBut who are the Grant, Kari and Tory of the synth world?
except these guys seem to actually like each other
They do have good chemistry
Neither of them are as annoying as Adam.
Good to have you back!
Damn right! Always a joy to watch you two work together.
I thought today would be the day I hear the words “Hainbach goes to Hornbach” (album name??) but I fear I may still have to wait a bit longer 😊
@@TanzmitTransmit just don't get too horny about that, haha!
This was an absolute joy to watch...
Watch out, he's going to steal your spare room and declare WG, and never return to Britain.
When Hainbach and Sam are going to Obi, you know it's gonna be good.
I wish there was a regular segment where those two could go to a hardware store and build mad instruments from random stuff they buy there.
Cool idea for a reality show.
That was almost the concept for the show that he made a couple years(?) back! Really entertaining, maybe this could be the V2.
Wasn't that Sam's original "regular segment" from the early days of LMNC??
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."
😂
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.
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.
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.
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.
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.
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.
Sproing reverbs... Also don't forget the non-electronic Echo Mike soundtoy.
Two guys tooting into hoses in the hardware store is one of the best things I've seen on the internet this year. 😂
Together with mouthpiece and a traffic cone it makes an Alpschlauch (portable wannabe alphorn).
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.
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.
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!
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.
Cool tip!
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.
theres so many different hoses, you could just have a collection of different ones to swap in
@@TDOBrandano Heat it up and you could pull it into a tighter coil than it ships in...
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.
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 😊
It's worthy of a like just watching you two walk around a B&Q playing a hosepipe. I wish we could have caught a customer or workers reaction. Oh it's those two nevermind 😁
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 :)
What a great idea. Could even be expanded on by using electromagnets to damp/excite the spring rhythmically.
"Next week, we'll learn how to make a looper with a coffee grinder. Stay tuned!"
Love it reminds me of old CRT TVs that had a time delay component that was just a length of wire proper old school.
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.
@@McSlobo The traces for RGB components in high quality graphics cards often had additional curves to make them exactly same length to avoid delay.
Watching two buffoons trying out the accoustics of garden hoses in a store makes me feel so much less lonely in the world it actually brings tears to my eyes.
Aye!
With the dry/wet ratio set right it's blimmin' great.Quite inspiring really.
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!
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.
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!
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)
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.
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.
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.
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).
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....
That sounds so awesome! Thanks for the video!
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.
Wow what an awesome effect from such a mechanically simple idea!!
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.
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
Try a PA horn. Works great and pushes a bit of air
The hose delay could also make multiple analog signals of the hose mixer into one , Y-Type Tee :)
A mechanical mixer. Needs some valves for each channel, but I like it!
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.
Analog TV camera used length of coaxial cable to create some accurate delay (like line sync, etc.) to create the appropriate TV signal.
Hah. Very cool.
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 😊
I only know this much from homemade wind instruments.: corrugated hose gives more growl.
I love the chemistry between you guys!
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!
absolutely fantastic feedback and odd tone from this. Love the general "playing around" approach too.
really liked the vlog style part at the beginning, Good to have you back!
Love your video's and I have nothing but respect for you and the way you make good music. Keep it up please!
The guys at OBi were like wtf dudes, when they saw you blowing these pipes :)))) ❤
Cool idea. I still remember from one summer I did some construction work that a piece of metal duct work does an amazing reverb. Fun stuff. :)
Always happy seeing you both :D
unbelievably righteous commitment to the craft
I can't believe how good this sounds.
this is actually some of the most entertaining content online, next to what rob scallion and andy huang do. their all wildly talented.
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.
These things were also used for communication from bridge to the engine room in steam ships.
I would have loved to have been a musician back in the early days of electronics and tape recording... imagine the fun to be had with seemingly unrelated, everyday items... and that case for the hose reel is just perfect! Imagine carrying it to a gig or something and someone at the bus stop notices the 2 innocuous connectors in the side, would be a great conversation starter!
Thats really quite effective, might have to build one! ❤
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
You can use the speakered tube as a talkbox also!
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.
Super good content! thank you for sharing.
That is so cool. The things people think of!
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
sgctactics, exactly!
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.
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.
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.
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.
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.
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.
Never seen coils of 15mm, but you can get coils of 10mm and 8mm.
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
PE hose for drinkingwater or floorheating is probably cheaper.😊
Nice, I spent all morning making a test environment to check my roundtrip latency for what would ultimately be a multitrack recording system in puredata. It's all delays.
These guys are magicians.
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…?”_ 😂
Seeing you two playing together like adult kids in an audio candy workshop makes me so happy 🖤
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".
Plat = plate.
Awesome Episode, thx for taking us along the ride
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. 😄
Delay lines were used as digital memory in the early days of computers. They used a metal wire instead of a hose but otherwise the same thing. You had to read the entire memory and retransmit it constantly
The Friden EC-130 calculator use a coil gong and all-transistor circuit for a serial 1-bit digital computer with CRT that fits onto a desk.

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!
Add an Y junction between 2 hoses for mixing the outputs. I guess that plenty of brass instrument principles may be repurposed for this.
I would gladly watch a series of you two just messing around with music ideas.
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 UA-cam with her and the Melvins where she uses an old bulb(also a pickle) to make distortion too. UA-cam Melvins Pickle Solo
So good to know others have also seen Sylvia Massey and read her book Recording Unhinged 👍🏻
I'm yet to get her book but im aware that its got some cool creative techniques in it. Some which she has shared in videos@@Bridge_Studios
that's really cool.
I made one of those long time ago. They were used as Pre Delay in movies. Like when a person walking through a tunnel, and then added reverb ...
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.
Probably a good thing you left it with Hainbach.. Imagine trying to explain that to airport security 😂
definitely a bomb
Hainbach and Sam you two remind me of Pinky and the Brain, but you are both Pinky and the Brain at the same time. 😅 What are we going to build today Sam? The same thing we do every night, Hainbach: Build a crazy music contraption!
You forgot the "the same thing we do every night, pinky..." bit
I would never think that such a simple thing would actually work 😮
I dealt with coil spring delays a lot time ago. Instead of sending the sound down a pipe it sent it down a coil spring. They sounded good for being such a strange thing.
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....
Musical plumbing for the 21st century!🤣🤣🤣🤣 Nice one guys.
Is there a Nobel prize for "two dorks in a hardware store misusing the garden hoses"? You guys just won it.
I hope this is all that remains of human culture when extra-terrestrial archaeologists discover our ruins millions of years in the future.
I thought the Alpschlauch was the strangest such contraption (portable alphorn surrogate with traffic cone end).
Sounds Way GOOD
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.
Glad i'm not the only one who checks to see if the glue is still hot right after it's put on.
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!
Oh I am certianly going to mess around with this.
"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).
What about running sound through pipes, say like an old house’s plumbing or some industrial machine full of pipes or coils…
pretty sure the blue man group owns the patent on that - they'll sue you
Maybe you could apply an ascending EQ to the drive, to balance the muffling
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)
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.
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 ...)
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.
Loved this video
Love this! Sylvia Massy has a similar set-up she uses to mic drums
Seeing you with the funnel and hose reminded me of Urban Spaceman by bonzo dog doo dah band, excet they used it like a trumpet, but swung it around
The delay reminds me of The Symphony of Bang Goes The Theory
That Pipe Dreams track is dope!
Very classy. I am quite surprised about how "expensive" it sounds.
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
I think a small hole at both the speaker and mic end will reduce the resonance of the air column in the hose, and shift the frequencies that get through a bit higher. A bit like playing the highest notes on a recorder.
A bigger volume at the speaker filled with something like fiberglass would help a lot. This thing is far from airtight.
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!
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/
Nice Rusko reference with the album cover! Got _Songs_ on vinyl 😁
