Recorded before the sun rose, rain and the occasional bird chirping. I thought it would be clearer that the rain is hitting the tin roof of a nearby building but it barely comes through. Recorded with zoom h1n.

Airplane passing overhead, 50s sounding engine. Lots of sub rumble, very dynamic sound effect. Sounds very close, like the plane is passing barely above.

The very real sound of a wide leather belt, folded into a double strap and mercilessly applied with unnecessary and unexpected speed, and force. The impact was against a defenseless bare bottom. Mine. This was the only strike that had no expressions mixed.

Yeah, it's so screwed up you can barely tell it was from that sample. That ringing in the back is a stretched and pitched piece of the same sample. I was trying to make a dub loop, but this is what i got. Really freaky.

A neutral, static room tone - with some reverb og distortion. I have used it in the background for radio shows, when recorded in a studio that's too silent - but of course mixed down a lot so you can just barely hear it.

A weird, lonely sound, made in logic pro x with a nice soft pad from fabfilter. I've added a gentle touch of reverb and the subtlest of an echo, barely perceptible. It's all yours to use in your projects.

Lowest string (f1, gauge 0. 74) playing again, but this time with heavy distortion and no reverb. There is some barely noticeable noise towards the end, picked up by the guitar pickups. Djenty, almost bass guitar stringish tone.

This is my old bedsheet being torn apart with bare hands. I have recorded this in 96khz/24-bit with a zoom h2, then normalized and saved as a 16-bit. This sample has a lot of sounds of tearing (unedited) so i think anyone can find something useful in it :).

That couple that lives next door. They are still doing what they do, but it seems like they no longer make the noise loud anymore. I can barely hear them. Either they decided to keep it down or that woman is no longer a screamer in bed. Note that most of the audio was amplified, edited, and cut short.

Ok this is going to sound like an 8 year old trying to convince his 23 year old brother that fnaf is real so bare with me. This is a real noise i heard, if it is just a regular sound the wind likes to make from time to time please tell me, i genuinely want clarification on what this is :).

I used my vape to make a gentle snake hiss. Worked out rather well, most hisses i've found barely had more dynamic than white noise. I think this fills the request for a snake hiss that's more dynamic. I will also upload this as a rainstick because it is similar.

A man laughing so uncontrollably he begins to have trouble breathing. May or may not be watching pauly shore movie. Hard to tell because you can't hear the movie, but it should be assumed as the man can barely breath from laughing ergo must be a pauly shore film.

Five is four: a polyrhythmic analog-synth loop with ambiguous five or four time signature. Slightly frantic sounding, arpeggiator-like rising pattern a bit like a shepard tone, it's a 5/4 pattern, but accents are distributed in 4/4. 180 bpm, key is a-minor (a-minor then f-major). Two loops marked in wav file, first is the bare synth pattern, loop is samples 0 to 640,000; second is with a pad, loop is samples 960,000 to 1,600,000.

I thought i would do a recording of me listening to truckers on the cb radio while i was seeing if i would pick up anything. Surprisingly, i was able to receive something because sometimes i don't pick up anybody because barely nobody is on it. Sometimes you can understand what they say but sometimes not all the time. Enjoy! recorded using apple voice memos on iphone.

File i recorded while at work on a telephone pole. I found a span of the steel cable they string between the poles that hold phone lines or cable lines. But this was just the bare span and nothing touching it. If you hit them with a wrench they make weird laser gun sounds. Recorded with my phone and cleaned up a bit in audacity. Use as you please. If you use it for anything interesting and want to share what you used it on, sure let me know. Enjoy.

Searched everywhere for this sound and was astonished not to find it. Very basic slap of the bare palm over the opening of an empty glass bottle, while holding the bottle in the other hand. I don't have good equipment or environment, but i figured you all could use it anyway if there's nothing else out there. If i overlooked one feel free to link me in the comments. Recorded with iphone 4s built-in mic.

Recorded around the plantation fields of kompolt (hungary), near the plant research institute. There are long dirt roads around the area, it's a big open place, so whatever wind, breeze comes barely anything could block it. That's why sometimes the recording's quality gets bad at places. Sounds: walking on dry, solid dirt, rocky-dirt, dry grass, walking through bushy areas, concrete at the end.

A recording of dry leaves skittering across an asphalt parking lot around 2:00pm on a friday afternoon. I feel this recording captures the serene, but sad, sound of dry leaves in the fall being scattered about by a strong north wind. Recording made with the marantz pmd661-oade, and the incredible beyerdynamic me58 microphone. Since this particular microphone is a dynamic microphone, i had to crank my record gain up to 7. I was really happily surprised that the sometimes un-listenable wind-roar and wind rumble is barely noticeable on this recording. . . . . . Emjoy this autumn soundscape.

This was recorded as part of a tracking shot for a project i did a few years ago. It starts off from the exterior of a fancy london pub around the primrose hill area, walking in to a fairly packed establishment. It tracks movement into different parts of the pub. There's fairly prominent music for the first half but it eases off to barely audible later on in the audio. A few minutes in, you'll hear the bartender announce the price (6. 95) a couple of times. Recorded on zoom h6 with x/y capsule.

Towards the end you'll be treated to a group of blue jays making a huge racket!other than that, no animal sounds at all. Just the slow, steady tip tip tap smack of raindrops falling from a cold-steel and gray sky. Recording made with sound devices mixpre-3 series ii, in 32 bit float mode.

My fifth attempt at a glitch style loop. In order to make the samples used here - most of which are only hundredths of a second long - i took samples from the amen kit, then switch the format from >pcm 22. 050 khz, 8 bit, mono< into >adpcm 11. 025 khz, 4 bit, stereo< then back to >pcm 22. 050 khz, 8 bit, mono< again. I found that if you do this with a sample under 00. 35 seconds long, you get an almost random glitch sound, about. 04 seconds long, that barely sounds like the original sound. I just figured this out, but i'll make note of it; i like some of the effects.

Sparrows flying from branch to branch in a bare rose bush. Unintentional capture of sound as i was just out walking testing new equipment. 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 no processing to this recording other than to ‘normalize’ the levels. 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).

Pre-dawn recording of the city of warren, mi (detroit's largest suburb) waking up on palm sunday. Recording is from 5:20am to 7:20am. Sunrise was at 7:13am. It was a cold crisp clear sky morning, 29f / -2c, barely any breeze. Pretty much a quiet track of early springtime birds, robins, mourning doves etc. , city hum & distant traffic building up as the city awakes on this beautiful palm sunday 2023. Recorded on a zoom h1n. Had to upload it as a flac, cause it was just over a gig as a wav. File.

This is the ambience i created for my sci-fi sitcom accidentally reckless of a dropship of some kind approaching a battlefield (and certain death). The bare bones was created from a field recording of the x-1 bus going down attercliffe road towards sheffield city centre, during a period in 2017 when they were constantly resurfacing the stretch that goes past the swingers club, resulting in the bone shaking rattling sounds you can hear. I then layered on some laser and rocket noises (already uploaded) and some engine type sound effects and shuttle flypast effects that i don't think i've uploaded yet. I hope it's useful for someone else and no need to credit. Just share the freesound love!.

Late august here in the midwest is the time for the loud choruses of insects. This recording, done in the backyard of a small town, features the classic"ebb and flow and swell" of the dusk insects. Since a park is nearby, you also hear in the background the excited voices of kids playing---maybe these youngsters do realize that soon they will be back in school and that the joyous, careful time of summer play and reflection will soon be over. Recording made with my zoom h4n recorder using its built-in internal microphones. The volume was set on 80. Enjoy, and maybe you too can use this sound-file for your own meditation, or simply thinking and taking stock of the accomplishments and blessings during the outdoor seasons and comfortably contemplate the upcoming dark, and bare and gray seasons ahead.

(recorder: zoomh4npro 2018)(microphones: zoomh4npro 2018 on-board microphones). This is a recording of illegal fireworks being launched all over los angeles on the 4th of july, 2020. All surface to air fireworks are illegal but, due to covid-19 cabin fever, people just didn't care this year. This recording is almost 99% voice free. There was a couple on a balcony that are barely heard muttering something in just a minute or two of this recording. For the most part, it's clean. I kept the peaks very low to maintain a natural sound. All of my sounds recordings are provided free of all charges. I give all rights to the down-loader for any purpose either personal or commercial. Enjoy!. Christopher c. Courter.

It's a recording of three emtec cd-rs being broken with bare hands. I had 3 audio cd-r that were burned useless. I decided to record their last sounds. You can hear the cds cracking and breaking, me bending them and trying to break them - they were pretty elastic - i had to learn how to crack them. So at first i had some trouble. Around 0:45 you can hear as i'm bending two cds together they squeak and crackle but don't break. The sound is not edited (hence the tag "raw") - no processing was done - i just truncated the beginning and the end leaving you everything you might need. Recorded with a zoom h2 placed on my bed. I was breaking the cds above it. There was a lot of splinters around, you can hear me fiddle with them from around 2:10 on. Originally wav 96khz/24-bit. Truncated and converted to flac with audacity.

Damaged smartphone screen protector being broken and crushed in bare hands (should've used gloves. . . ). Recorded with behringer b-1 microphone into focusrite scarlett 2i2 3rd gen. Into audacity on arch linux at 192 khz/24 bit. The recording was not processed or edited in any way to retain maximum flexibility to sound artists who will use this as an element. This can be useful as a sound effect for freezing or burning or deep-frying or even rain (when slowed down). Thanks to extremely wide frequency range the recording can be cleanly slowed down up to 25% speed. There's clean frequency content up to 80 khz in the recording. In a few places the mic gain was too much and a pop is clipped, but could still be useful for sound of braking or snapping something (bone?). No denoising was applied - perform your own if needed, though the sounds are mostly free of background hum (a bit of pc noise can be heard in the first minute before i turned down the gain).

A peaceful ambiance of some pine trees in early, early spring. The predominant, lower-pitched background is the strong south wind blowing through the tops of healthy pine trees. . . An unwavering "swooshing" that cuddles and curls around the flexible, thick-resin-filled pine needles. Also, from time to time, you hear the sound of the wind rattling some dead and brown oak leaves; oak leaves which are still stubbornly hanging on to their parent tree. I purposely did only a very bare minimum of post-processing on this sound so as to keep it as realistic as possible. Yes, there are quite a few wind rumbles that i toned down just a little bit. I did not totally get rid of the wind rumbles. I did this on purpose so you the true feeling of " being there " on that mild, but still raw cold day of spring could still be felt. At 4:35 into the soundscape the trilling of a pine warbler is heard---a warble of warm-sounding notes fighting back stubborn winter. At 9:33 that hardy year-round resident, black-capped chickadee starts tweeting about. Recording made on saturday march 25, 2023 using a sound devices mixpre-3 series ii and only one microphone. I used a sennheiser mkh 8070. Enjoy this soundscape of winter slowly losing its grip, as told by pine trees and brown, crackly oak leaves.

So you liked surprising her. Here's what it feels like, dude bahahaalso, what it sounds like. A first foray into educational response, the subject slowly awakened in handcuffs, barely aware he was rapidly losing his shorts. Totally unsympathetic cohorts then lashed ankles quickly to both ends of a broomstick. Free to do as they please, unplanned things can happen, and did. Oh, dear. 😯 well he was completely vulnerable. You mean. . . Yeah. They did. 😼 at that point i think he was awake. His victim had selected the broadest and longest, high-output motorized appliance to be found, complete with bulging veins. . . Eventually, at her hands and from her “deep” feminine resolve and with considerable force, the nautilus made port. Ta-daa!! lubricant sure wasn’t needed anymore but had spent the night in the fridge. So she used it😬 end published audio, but not the still-expanding asshole, um, event. Take-away: if you cannot be respectful, at least be careful where you sleep. In fact just a bit later, the enhanced vibrators and integral power-stroking were switched on. Gracious. He didn’t know it had an “on” 🙀 and just about went wild. A lovely, cohort-induced stiffy relaxed and then, any semblance of bladder control did too - oh, oh my 😸 😹then we left.

I won't claim that this is a ghost as i am sure many would debunk, only that i believe it to be. This is an evp i found during playback for something else i recorded in audacity with a usb condenser mic. This happens a lot and i have quite a few. It sounds to me like a voice that is not mine is saying "watch" i cleaned it up as much as i could but this was barely audible originally so i had to bring up the volume a lot which made the noise floor pretty loud. I did some noise reduction to make it sound cleaner. I have personally had experiences that i believe to be supernatural but decide for yourself as you listen or use it as make believe. I have more i will upload when i can including ones from places that have been researched and said to be haunted (taken on my phone). I have to find them but as i come across them or new ones i will share. No need to credit me, i am just sharing this for fun. It creeps me out, and gives me chills so hopefully it does the same for you mwuah hahahahaha! enjoy ;).

Street noises recorded while walking through the most touristy area of montmartre, in paris, france. Streets visited include rue des saules, rue norvins, rue du mont cenis, rue du chevalier de la barre, rue du cardinal guibert, rue azais, rue saint eleuthere, in that order. Highlights include:. 00:00-00:30-> walking south along the relatively quiet saules ("willow") street in montmartre; footsteps and squeaking boots. 00:42-01:02-> street-cleaning truck passing on the same street. 01:02-01:30-> piano playing inside a restaurant on norvins street. 01:30-01:36-> rock music in some other shop. 01:44-01:46-> kids running past. 01:56-01:58-> barely audible music somewhere, under heavy crowd sounds. 01:56-02:59-> crowd noises, clinking silverware and plates in the restuarants i'm passing, increasingly heavy crowd. 03:00-03:21-> passing van, followed by another bus. 03:21-04:06-> ill-behaved young males ruining my take with strange ape-like cries. 04:06-04:17-> i think this was a passing taxi. 04:20-05:08-> someone playing a steel drum on the ground in mont cenis street. 04:43-------> someone closing a gate, i think. 05:16-05:18-> american tourist exclaiming at close range in chevalier de la barre street. 05:53-06:18-> street portrait artists talking and joking with each other. 06:30-07:25-> someone playing the harp on cardinal guibert street next to the basilica, partially drowned out by a passing car. 07:25-08:23-> someone singing on the steps in front of sacré-coeur. He had a powerful but distorted amplifier--the bad sound quality was like that in real life. I turned around in front of the basilica on this dead-end street and that's why the music switches sides. 08:23-08:40-> yes, that's a chainsaw. The city was trimming some large trees. 09:33-09:47-> more chainsaw noise as i walked past the workers on azais street. 10:00-11:00-> increasing crowd noise as i walk back north to the busiest part of montmartre along saint eleuthere street. Recorded with a hand-held h4n at 96 khz / 24-bits, stereo, compressed into 160 kbps / 44. 1 khz / 16 bits mp3. Recording date march 16, 2012, in the early afternoon.

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. 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.
