Effects recorded from the field. Recording gear-zoom h6 and microphone oktava mk-012-01. Layering in reaper 6.

This is a recording of very low frequency hum of a steel mill. The sample has been low pass filtered. The main frequency is about at 25hz. The sound was recorded some distance away of the steel mill area, where it mixed with other sounds as a constant hum, which could be felt in body too at certain spots.

This is an old sample that i recorded a while ago. Not sure where it came from but i think it might be a sewing machine, or some piece of industrial equipment.

It's some water machinery working in a house basement. Captured with a zoom h2.

Taped a pair of jrf c-series contact mics on a small, very quiet wristwatch to see if i could get a good signal. Pleasantly surprised by the result. Removed the quartz hum and de-noised in rx 7.

This is a sound design with a mix of bike chains, a car and room door and a rolling ball to create the sound of a large, intimidating elevator sound. Enjoy!.

The sound being heard is thearcano r3 chiptune synthesizer. The guitar pedals used:ehx- big muff pi op ampzoom- multistomp ms-70 cdrmooer- slow engineehx- attack decayseymour duncan- shapeshifter.

A mini-fan motor pushed against a mic. Recorded and processed with audacity.

A recording of my neighbours leaf blower that has pissed me off for the last 5 years! i used it for a videogame about construction, so hopefully it can help some other people too. :).

-service industrial fan outside apartment screaming-96khz/24-bit stereo.

This is an old commercial refrigerator from the grocery store. It was making a very nice regular droning sound so i placed my phone inside the fridge to get a clean recording without the noise from the store. Perfect for a spaceship drone or background noise at a factory.

-service industrial fan outside apartment screaming-96khz/24-bit stereo.

This the sound the gantry makes when performing its "front-cut" cycle. Recorded with my pixel phone. Processed through the sound removal feature in audition to clear out the background hum from giant air conditioners in the shop.

Workers working on a street in porto, portugal. The workers open the street and used a digger. One guy used a shuffle. Recorded with zoom h1 and cut with adobe premier.

Recording of a bosch refrigerator. Recorded and processed at 24bit 96khz using the tascam dr-40 linear pcm recorder. Processing: gain-staging and soft high and low frequency filtering. No eq boost or cuts anywhere else.

Dark growling drone sound i made on a my behringer model d analog synthesizer, recorded with effects in ableton live. Some processing was done later in adobe audition to finalize it.

A clothes dryer makes a mechanical noise, because of a cloth which knocks against the edge, making loud noise. Rhythmic and metalic. Here recorded very close, in mono, with h5+sgh-6. Other perspectives available on my profile.

Recording of an industrial size single cylinder compressor. Interesting sound at the end of the recording when the compressor have finished its cycle. 96khz 24bit stereo wavtascam dr-100mk3.

I like the sound of the failure of some electric devices, so i made a new pack only for those sounds. This is a piano melody, but i added a effect named laundry chorus of live 9. The melody is unrecognizable but the sound is awesome. Enjoy it!.

A clothes dryer makes a mechanical noise, because of a cloth which knocks against the edge, making loud noise. Rhythmic and metalic. Here recorded from the corridor next door, in mono, with h5+sgh-6. Other perspectives available on my profile.

Running a cycle on an industrial grade coffee machine. Features a loud click, machine noises, and water pouring noises. You can get the water pouring isolated, or with the machine noise in this sample.

Large ship 40 metres long boat with engines running. M/v blue horizon, operating in the red sea. The engines shut down about 1 min in leaving the sound of the power generator and air conditioning. Recorded with a contour+2 camera.

An long escalator i recorded in atlanta. The escalator was very noisy, and produced a kind of whining electrical sound that sounded almost spiritual. I do not know if the transcendent beauty of the escalator is captured sufficiently here, but i figured someone might be able to use it! there are a few faint voices in the background.

Cold booting a computer built inside of a milk crate, allowing it to start up and start running a stress test, and then hard shutting it down by flicking the power supply switch. Multiple computers were running in this room and this recording is unedited, so there's some extra background noise. Sorry.

A broken fridge at a place i work sometimes. Starts off sounding normal enough but then slowly starts going crazy, i'm no refrigeration expert but i'm pretty sure there's something wrong here. Made me jump when it makes that first noise :p.

only 90's kids will remember. . The sound of a generic car-stereo tape-deck's motor. Slightly eq'd to narrow the spectral range of the low-quality recording device. Recorder: smartphonedate & time: ?location: fremont, ca (usa).

I asked for a fabric shredder because i couldn't find one, and i knew my dearest would knock himself out trying to. He didn't either but he did have one made, probably at considerable expense. It's a cute little portable unit, i think made of a modified paper(?) shredder, powered by a geared motor from a battery-operated power tool. It's probably a dangerous little work of art. So we're getting dressed in the bedroom after opening gifts on christmas morning, and i decided to try out my new toy. Good conversation, mechanical whir.

Picture yourself being abducted by a highly advanced alien race, you're trapped inside one of their crafts, being far far away from earth at this point, i guess this is a soundscape that reminds me of it, created by experimenting with various free plugins including dtblkfx and thesis2b, both amazing tools on their own, more than capable of giving you glitchy squelchy hi-tech sounds.

Tiny waves lapping the quartzite pebbles (1-2cm diameter) on a beach at lake pedder. Recorded 21 march 2019, 3am, with the internal mics on a marantz pmd661. For noise reduction, capture a noise print around 0. 09. Exceptionally quiet night, no wind, no other sounds. The gordon river power station was 20 kms distant. Other mechanical equipment or vehicles greater then 50 kms. I could just perceive the electrical hum from the station (or from transmission lines), and so could my partner, but i can’t hear it on the recording. See also "tiny waves lapping #1".

Tiny waves lapping the quartzite pebbles (1-2cm diameter) on a beach at lake pedder. Recorded 21 march 2019, 3am, with marantz pmd661 and rode nt55. Exceptionally quiet night, no wind, no other sounds. The gordon river power station was 20 kms distant. Other mechanical equipment or vehicles greater then 50 kms. I could just perceive the electrical hum from the station (or from transmission lines), and so could my partner, but i can’t hear it on the recording. At 1. 30 on the recording you can hear my partner’s soft cough coming from our tent 50m away. The crackles that sound like static come from the quartzite pebbles as they are moved around by the tiny waves. See also "tiny waves lapping #2".

I was surprised this still worked. This is an old ibm selectric ii typewriter, with correcting tape, the “quieter” selectric at the time. It’s about 80 pounds, a real back-breaker. The carriage return bell is broken, unfortunately, so the best you might hear it is rattling due to the belt vibration. Recorded with a tascam dr-05, without the low-cut since i wanted a beefy sound. Placed direcly above the roller, about 12 inches away. I swapped the channels in audacity to match perception & sampled down to 48khz. Description: i roll in some paper, type a few paragraphs from some copy, and roll it out when i’m done. Man, can you type fast on these machines!.

A short recording of construction work on a ten-storey apartment building in the blackhorse road area of walthamstow, london. General construction noises. This recording was made using a sound devices mixpre6ii and a stereo pair of fel em172 mics. Low cut on the sd which in basic mode is 80hz (i think). There is some processing to this recording to ‘normalize’ the levels and light eq-ing. I do not require any credit or attribution.

Several years back my older brother stumbled upon a bunch of old family reel to reel films and sat down one evening to project them on a wall and digitize them. This is the sound of that process. What you can hear, i imagine, is the noise of the projector in the left channel and the sound of the reels in the right channel. I've been obsessed with the sounds of the infinite variation in old analog hardware. As a sound designer, that infinite variation is often sought after but rarely, or accurately, reproduced through digital files in various libraries. Of if they are, they're often too short to cover whatever scene i am trying to fill. On the surface it's just noise but if you listen closer it's this wonderful cacophony of overlapping and repeating sounds that are always looping but never quite identical on each rotation. It was ripped from youtube using audio hijack at 48khz/16bit, but due to youtube re-encoding things as youtube does, it's nowhere near the source. It's still, in my opinion, a sound worth sharing. Enjoy!.

Here are the sounds i recorded:- the "loose parts" sounds were a slightly unscrewed valve on a trumpet. - the hydraulic leg-lifting noise was a hatch door opening on a van. - the metal foot hitting the ground was me banging on a metal garage door. - the humming engine noise (it's quiet) was a roll of duct tape spun on a wooden board. - the various other clanks and pops were the same trumpet noises, just edited a bunch. One day while playing the mobile game crossy road, i my sound being used for one of the characters. If you end up using my sound, let me know! i'd love to know what kind of things it's being used in. This is called "three-legged robot walker with loose parts" because it was a foley assignment for my sound design course years ago. This was one of the obscure things the professor gave the class that we had to interoperate and create using only our own recorded/edited foley effects. The class voted on the best one, and mine turned out to be the winner.

A few cycles of my dad's home oxygen machine with a ticking battery operated clock in the background recorded in the early morning in the living room with lifecam hd3000 webcam at the end of about 16 feet of usb cable dragged out of my bedroom. He's about 6 feet away, i was with my back to the room with my camera pointed at my chest so he wouldn't think i was filming. It would seem this is the first and only oxygen machine on freesound. A full cycle seems to last from between 7 to 10 seconds. From wikipediaoxygen concentrators typically use pressure swing adsorption technology and are used very widely for oxygen provision in healthcare applications, especially where liquid or pressurised oxygen is too dangerous or inconvenient, such as in homes or in portable clinics. Oxygen concentrators are also used to provide an economical source of oxygen in industrial processes, where they are also known as oxygen gas generators or oxygen generation plants. Oxygen concentrators utilize a molecular sieve to adsorb gasses and operate on the principle of rapid pressure swing adsorption of atmospheric nitrogen onto zeolite minerals and then venting the nitrogen. This type of adsorption system is therefore functionally a nitrogen scrubber leaving the other atmospheric gasses to pass through. This leaves oxygen as the primary gas remaining. Psa technology is a reliable and economical technique for small to mid-scale oxygen generation, with cryogenic separation more suitable at higher volumes and external delivery generally more suitable for small volumes. [1]at high pressure, the porous zeolite adsorbs large quantities of nitrogen, due to its large surface area and chemical character. After the oxygen and other free components are collected the pressure drops which allows nitrogen to desorb. An oxygen concentrator has an air compressor, two cylinders filled with zeolite pellets, a pressure equalizing reservoir, and some valves and tubes. In the first half-cycle the first cylinder receives air from the compressor, which lasts about 3 seconds. During that time the pressure in the first cylinder rises from atmospheric to about 1. 5 times normal atmospheric pressure (typically 20 psi/138 kpa gauge, or 1. 36 atmospheres absolute) and the zeolite becomes saturated with nitrogen. As the first cylinder reaches near pure oxygen (there are small amounts of argon, co2, water vapour, radon and other minor atmospheric components) in the first half-cycle, a valve opens and the oxygen enriched gas flows to the pressure equalizing reservoir, which connects to the patient's oxygen hose. At the end of the first half of the cycle, there is another valve position change so that the air from the compressor is directed to the 2nd cylinder. Pressure in the first cylinder drops as the enriched oxygen moves into the reservoir, allowing the nitrogen to be desorbed back into gas. Part way through the second half of the cycle there is another valve position change to vent the gas in the first cylinder back into the ambient atmosphere, keeping the concentration of oxygen in the pressure equalizing reservoir from falling below about 90%. The pressure in the hose delivering oxygen from the equalizing reservoir is kept steady by a pressure reducing valve. Older units cycled with a period of about 20 seconds, and supplied up to 5 litres per minute of 90+% oxygen. Since about 1999, units capable of supplying up to 10 lpm have been available.

Recorded in my dad's bedroom with lifecam hd3000 webcam. This is a much better recording than my previous oxygen concentrator file, as i hauled my desktop into the bedroom at the other end of the apartment where the machine now is, when i was home alone. The webcam is on the bed about 3 or 4 feet from the machineat the beginning of the file you hear me flip the big switch and the machine comes on with a long on beep and thumps. I edited it to start then. At 00:1. 8 what i suspect is the water pump comes on, though i may be wrong. That's when the gurgling starts though. The machine has a small reservoir for distilled water to moisten the airflow. A cup or two lasts several daysyou'll hear various hisses and thumps in a 15. 6 second cycle as it runs. At 03:03 i flip the big switch to shut the machine off, and it bubbles and gurgles away for the rest of the file, as water i assume slowly perculates back into the reservoir, the bubbling getting quieter and quieter until it doesn't even sound like bubbling anymore, until it finally ticks to a stop. At 03:16 you hear me step as i get my foot loose from the mic cord lol. At 04:13 the furnace shuts down as a car finishes going by outside in the bass register, faint traffic noises and the furnace being the only background noises you'll hear aside from my moving around a couple times, and a faint bluejay at the end. At about 07:00 you can barely hear the machine anymore, but i could hear a faint ticking with my own ears. At 07:04 the furnace comes back on. At 07:08 you'll hear a bluejay faintly calling outside and a car going by outside after, which finishes the file at 07:20. I edited out my walking to the computer to shut the recording down.
