817 Royalty-Free Audio Tracks for "Humming"

An mp3 version of the 4-minute recording of an apartment parking lot in a small neighborhood with a busy nearby roadway - from a different perspective. Cars can be heard driving by, along with a faint humming with from some machinery and a small amount of wind. There is also some faint talking, laughing and coughs from a group in one of the apartment buildings, which can add to the effect. There are two instances when cars drive into the parking lot (about at 3:20 and 3:40), and shortly afterward a person walks by the mic. Recorded with the microphone of a nikon coolpix camera.

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. If any of these sounds have been of help, and you are feeling charitable, please do consider donating to freesound to help keep the site running (a link is also on the home page).

Ambient sound akin to the bridge of a starship. Muted background hum with an overtone of air conditioning ducts. Pseudo-random high pitched blips occupy the soundstage. Could be used as an ambient sound loop for hi-tech / science fiction interiors such as a laboratory, a control room, or the bridge of a spacecraft. Created with two instances of flstudio 3x osc. One kicking out a pair of sinewaves plus noise for the background susurus (hum) and ventilation sound. Second 3x osc is set to produce two interfereing square waves for the blips, squeaks and buzzes. The background was notch filtered and bandpassed to mellow out the humming sound and reduce hiss. The blips were processed with flstudio equo, stereo enhance, fruity delay2 and fl pan-o-matic vst. Each blip was pasted by hand in a seemingly random but not too unpleasant pattern.

This sample consists of noise recorded via a hondo strat electric guitar resp. The guitar's neck pickup. Throughout the sample there is a low hum. In the beginning, a mobile phone was moved in front of the pickup. The noise might have been created by the clock of the phone's cpu or the backlight of the phone. After that, one crt display is switched on resulting in a buzz. Later on, a second crt display is switched on, again resulting in a buzz followed by additional noise in higher frequencies. Then, a neon light is switched on, creating even more noise. Towards the end, again the mobile phone. . . The guitar was connected to a scott&noble ht25r amplifier which was recorded with a t. Bone sc450 condenser and a behringer ddx3216 digital console directly into ardour.

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!.

The sound of an ice maker on a water cooler doing a few cycles. My amazing aunt harriet amazes again by sending me this sound of her ice maker. She taped her old iphone to the inside of the door on her new water cooler/ice maker combo, and let the ice maker run for a few cycles. She even typed up a description of what it does for me so i could post this here on freesound:the water is pumped from a reservoir underneeth the ice tray into a tray above that houses 9 pegs. The water is then cooled to freezing, while the 9 pegs are simultaneously cooled to hold the ice in place. More water is then pumped into the tray to thicken each piece of ice. After a few minutes, excess water is dumped back into the reservoir and ice falls from the pegs into the ice tray. The process then repeats. Enjoy and use however you like!.

Featured in the game 'noclip vr'!! thank you so so much, reality games online!. This is heavily inspired by the urban myth and/or creepypasta called the backrooms, which have a very distinct atmosphere to them. This is my interpretation. However, this isn't exclusively for backrooms-related stuff! so by all means, if you're simply in need of some interior ambience of any sort, that's also why i made this for you. No advanced processing was used to achieve this sound. I recorded an electrical box in my garage for the buzzing. For the 2nd layer, i turned on some fans in my room, and made a long mono recording of the white-noise. I then split the recording in half, and used each half for the left and right channel, giving it a stereo sound. I then spent an hour leveling all of it because i'm a perfectionist. Yay. Hardware & software used:-audacity-zoom h4n pro (buzzing)-rode nt1 (fan-noise).

I have built a nonlinearcircuits sloth lfo, the regular version. Sloth is a chaotic lfo. The output is based on the lorenz system. It is a system of ordinary differential equations. It is notable for having chaotic solutions for certain parameter values and initial conditions. In particular, the lorenz attractor is a set of chaotic solutions of the lorenz system which, when plotted, resemble a butterfly or figure eight (very much from wikipedia). The sloth has two outputs x and y. Think of them as coordinate pairs. The output will probably never repeat itself but there is a pattern. I have built the regular sloth it usually takes approx 15 seconds to make a rough figure 8, one cycle in the “butterly”. Now i’m testing the module in different ways. In this sound i have connected white noise to a filter. The filter frequency is controlled by sloth (x output). In this patch i have set the initial frequency low. That’s why there is a low humming wind noise between the “tops”. The output sound from filter goes to reverb. The sound is more a study of sloth behavior than an attempt to create a great wind sound.

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.

Electro-magnetic interference from a desktop computer, and an at&t; cordless phone handset cl82301 when held near the internal ferrite antenna on the back right of a 13-year-old boombox listening to the am broadcast band. Recorded 2 years ago so i forget where i was listening. Recorded with goldwave from line-in. You hear emi from the computer at first, then i bring the phone on standby near the radio and you hear a series of nearly pure tones. The phone comes on and you hear a distorted dial tone. I move the phone away from the radio for a few seconds and you hear the computer again, then i bring the phone near and you hear a distorted busy signal. I disconnect and the phone continues sending to the base for a few seconds so you just hear a hum, then the idle tones are heard, then the computer noise as i remove the phone.

Non-functional tube radio warming up, making a loud 60hz hum with lots of harmonics. As a bonus it clicks off at the end. Zenith consoltone. Only because the faq says so: electro voice n/d 257a through impedance transformer into crappy gigabyte motherboard realtek high definition audio. 16bits, processed at 32bits. Audacity sound editor and/or driver wouldn't record mic level so it was very noisy after amplification. Filtered with a (mathematically equivalent) fft constructed whopping 64k length zero phase filter (blackman window) with 5 wavelength width bandpass at each harmonic from 60hz to 5,520hz. For some reason a fraction of some of the harmonics didn't get through so did another pass on the residual noise and mixed that in. Near the beginning there was a sort of brief duplicate signal that descended in pitch so it didn't make it through the filter. I added that bit in. Attenuated frequencies above 3. 6khz because they are pretty much noise, but removing them didn't sound right. Cleaned up the beginning a bit in various ways, cut it down to 15 sec and carefully appended the unfiltered "click" onto the end, which i denoised 12db with audacity's noise reduction.

An actual new production instead of old stuff! made in june of 2020. A dark intro implies the humming engines of the spaceship you're in as you're traveling at speeds unimaginable. Slowly the ship starts to spring to life. As you open your eyes, slow but huge bands of light sweeps across your cryogenic sleeping pod, as if being scanned. The pod starts to move while you're still in it, going through chambers filled with machinery and bleeping computer stations, until it stops in front of a huge closed door. Suddenly, your pod opens up as well as the door. Your eyes are greeted with the majestic sight of a gigantic control room with windows as far as the eyes can see, galaxies fills your field of view, a beautiful synergetic view of the grandeur of space and the hundreds of lights of the control room, welcoming you to a new adventure. 2 simple chords form the basis of a textural composition supplied with sound effects. Plugins used: ni kontakt 5 with atom hub's the planet, doom by sampletraxx, space by rigid audio, ni absynth, and massive vst synths. Extra sound effects: shocking signal and ui designer by sampletraxx, heavily sampled and mangled. Effects: izotope mastering plugins, a bunch of fl studio stock reverb and eq, guitar rig 5, blackhole reverb, replika xt, raum reverb.

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.
