This is a small clip which i made playing the original video on my laptop and recording it on my cell phone. There is a noise machine on and a voice distortion tool being used and foreground dialog as well. It's the whispered dialog that is crucial in my quest for justice. The sample is to offer up proof that this is very real to those who may be questioning if i am indeed serious. Please reply with transcription of background dialog, or a cleaned up sample. Your help is so appreciated.

A sound i made in audacity, basicly a chirp going down from about 500 hz to 20 hz (with a fade-out to limit subwoofer use)and added some ambience by using white noise rumble on the background, also added a slight wah-wah as you might notice. Feel free to use it in a project as long as you give 'olaf gillot' credit. And of course 'freesound. Org' for having such an awesome website, with free hosting stuff :d!.

Please read full description. Sony ecm-ms907 microphone and a minidisc recorder probably used. Most likely recorded somewhere in brighton, uk;. . Please let me know if you use my sound, and what for. I would interest me and satisfy my curiosity as i'm a curious sort of person. I've designated this as public domain / cc0, however. . . . . .

This is the sound of a rat gnawing its way down through our wooden ceiling (and 2 days after this recording there was a hole about an inch wide in the ceiling!). Recorded july 15th 2015 around 10 o'clock in the evening in the livingroom of my house in fredensborg, denmark, with a portable recorder zoom h2n. The soundfile was then exported from the recorder to a windows pc through usb, and normalized (i. E. Amplitude brought up to 0 decibel) using steinberg's wavelab software before uploading to freesound.

It annoyed me i couldn't find this atmosphere anywhere here, so i decided to build this for you: remember the classic "thunder rolls then a wolf howls" sound bed used on so many kids' shows back in the 1970's? well, here you go! this is uses the classic thunderclap by a freesound user whose name i can't remember but will ad when i do remember, some more classic moaning wind by me, a retro wolf howl performed by yours truly with added reverb on top. Use freely and enjoy.

The sound of an electric car being plugged in and recharged. The clip starts with the car's recharging flap being opened from inside the car, then fully opened by hand, then the plastic socket cover being opened, then picking up the charging connector and plugging it into the car. There is some clicking as the electric vehicle's cooling fan turns on for a short while. This was recorded in-person with a tascam dr-40 stereo recorder at a small, suburban farm.

Does freesound really need another recording of someone washing their dishes? maybe not, but this is a longer take i recorded for a film project - because when you're editing, it's frustrating to find a good recording that's not long enough!. Includes plenty of dish movement, running water, scrubbing, etc. Some limiting was applied to tame the biggest peaks. Mics: schoeps cmc6 mk4 stereo pair in xy configurationrecorder: sound devices mixpre 3 directly into reaper. Please note that this is a 48k 24bit flac file - flac files can be easily read and converted by audacity [https://www. Audacityteam. Org/] and reaper [http://reaper. Fm/], among others.

Recorded in june 2016 on a hudson yards-bound 7 train in the new york city subway. Towards the end of the recording, at the last stop (34th street–hudson yards), there is mta thank you announcement at the station and for all passengers to alight - i have extracted this announcement as a separate audio download on freesound if that's the sound clip you're interested in!. Recorded with a zoom h2n in 4-channel mode - this is the xy recording only (msg me if you want the raw ms recording!), without a windshield. File has not been modified.

A sputtery drum beat. The bass is from freesound, the snare is from a small chop of my fist hitting an oil drum, and the small breath that acts as percussion is from a children's toy. The hi-hats are from vinyl crackles and mistakes in other recordings, made to sound like the crackles themselves are making the music. 88 beats per minute. Used this in my song tai chi, chai tea: https://soundcloud. Com/user-32192831-668958257/tai-chi-chai-tea.

This is a compilation of freesound files. It is intended as background atmospheric sound. I find it stands by itself, so i am uploading it as is, though i added more layers to it as "scary night complete". Loops, cycling from calm night through a windy, brief storm. Really ought to be longer, but. . . Formed from:171984__kyster__massive-hail-and-two-deep-thunderbolts-2012-11-02191934__klankbeeld__creacking-oak-6bft-short-130418-0023405__neilg__rainonleaves-june2006245824__1ratatosk1__nightscapes-asplund-ett-min253535__kvgarlic__windblownleavesskitteringacrossasphaltoct31st2014267551__yoyodaman234__thunder2267550__yoyodaman234__thunder3267549__yoyodaman234__thunder4272322__klankbeeld__wind-in-willow-02-contact-mic-150426-064462488__sagetyrtle__1103octobernight83985__inchadney__owls.

Warning: files can not be undeleted, not even by administrators!i re-uploaded the sound because there was an error connecting to the https://freesound. Org server. Estimated start pitch: a♯/b♭1 (59. 940 hz)this is an impulse of 59. 94 fps video (see why tv is 29. 97 fps and the horizontal frequency is 15734. 266 hz). I created this in audacity!. Silence: 1001 samples at 60000 hz, except the first sample is of amplitude 0. 25. Attribution is not required, which means that i, therandomsoundbyte2637, need not be attributed to use this!. Sample rate is 60 khz because of the 59. 94 hz.

Welcome to rome. We needed some drum cadences for julius caesar and i was unable to find any i really liked so we grabbed our orchestra drummer here at the theater and we came up with 13 different cadences for us including jfk's funeral march. Most are done on snare and then again on a single tom, easily looped for duration. They have no verb on them so you can add as you desire for your space. You are free to use these samples in any project you are working on. Just say hi here and let me know what you're up to. I like to know it's helping a fellow sound designer out. Enjoy and support freesound by uploading your own creations as you make them. Kiddpark.

In-cabin recording of a qatar airways boeing 787 dreamliner landing at doha international airport (qatar), followed by announcements in arabic and english.

Here it is! my first ever submission on freesound! i decided to start this all out with a bang, and post something really cool that i'm proud of making. I'm not sure exactly what this creature was supposed to be. I'll leave that up to your imaginations. How it was made:. Software: fl studio 20. Plugin(s): serum, valhallaroom, ott, fruity parametric eq 2, and fruity delay 2. This was made completely with synthesizers. I used serum for the main synth, made copies of it, and modified each of them to sound unique from the other. I'd try to explain how the synth was made, but there's a lot of stuff. To process it, i used ott to make it sound more powerful and clear, eq to get the frequencies and texture right, delay with a low pass filter to get that outdoors echo feel, and valhalla room for the reverb. I had fun making these. Enjoy!.

Created for an upcoming film, this is the audio from a nightmare a character in the film has about the terrible 1966 aberfan, wales disaster. He sees himself in a hallway at pantglas school then hears the coal tip land slide coming, then sees it crash through a distant wall and come rushing at him. I put it together from the following freesound samples:. 94114__tim-kahn__rumble126323__klankbeeld__horror-zombie-hell-atmos147239__matiasezcurra__mud-and-rocks-river-iruya-northwest-argentina168777__robinhood76__03792-children-screaming198095__cell31-sound-productions__earthquake-interior-metalrattling-2244501__hutsvoid__nervous-children249907__klankbeeld__horror-kids-01338721__rogerboyx69__inside-a-tornado379906__kevint1001__water-flood-enhanced402016__ylearkisto__ikkunoita-rikotaan-kepilla-breaking-windows-with-stick415608__rtb45__mud-volcano-field-salton-sea456806__breviceps__hot-bubbling-mud514381__zatar__earthquake3343130__inspectorj__ticking-clock-aand145801__mrbriandesign__kids-screaming-2. This was a very difficult piece of sound design to construct because of my emotions about the disaster and how the national coal board responded: 500 pounds sterling maximum to each grieving parent for each dead child, and with questions such as, "how close were you to your child?" if the answer was somehow not close enough for the panel, no money was awarded. The film scene will be handled with taste and respect, and no dead children will be depicted.

This file is limited to 1 hour because the use of a larger bit-rate and the amount of noise used. Helps with many sound pollution problems and audio-stimulus problems such as: sleep, concentration, tinnitus, headaches, and so much more!. If this has helped you, please share your story in the comments below and feel free to distribute this all over the web to help others!. I am leaving the original file https://freesound.

I recorded these spring peepers in upstate ny on march 18, 2022 in a wetland area. Spring peepers are small tree frogs. They are rarely seen, but during mating season in the spring, they are often heard. They are generally about one inch (2. 5 centimeters) in length, or about the length of a paper clip, and their weight averages from 0. 11 to 0. 18 ounces (3 to 5 grams). Spring peepers are known for the males’ mating call—a high-pitched whistling or peeping sound repeated about 20 times a minute. However, the faster and louder they sing, the greater the chances of attracting a mate. They often congregate near water and sing in trios, with the deepest-voiced frog starting the call. They begin breeding early in the spring and call on warm spring nights and during the day in rainy or cloudy weather. Females lay their eggs in vernal pools, ponds, and other wetlands where fish are not present. A female may lay anywhere from 750 to 1,200 eggs, which attach to submerged aquatic vegetation. Males fertilize the eggs as they are laid. Depending on the temperature, eggs can hatch within two days to two weeks. The tadpoles have gills to breathe underwater and tails to help them swim. Tadpoles transform into frogs over the course of 6 to 12 weeks. Spring peepers are said to have short lives, living three to four years at most.

This is a reading from the second chapter of "nathaniel's nutmeg: or, the true and incredible adventures of the spice trader who changed the course of history", by giles milton. It is also intended for the freesound sound museum to represent books as what is fading rapidly into obsolescence. By the time you read this, you may not even know what a books is. Books are when the written word is compiled onto sheets of paper in a long-form volume. You may not know what paper is. Paper is commonly used to write on or make oregano cranes with, being flat and thin rectangles made from trees. You probably won't remember what a tree was. That is a very sad thing. They are all gone now, destroyed in feckless deference to paper. When the paper runs out, there will be nothing left to write our collective histories on, what we desperately need. When this occurs, it will stand as the moment our past was truly lost, leaving us lost the same, drifting in circles. Until another man or woman rises up to invent trees again, thus beginning the cycle anew. It's a beautiful idea. We should always be moving towards the future, not lost in syrupy memories of old forests not seen for what they really are: petrified wood and amber. Leave that with the other fossils and relics. Let it be the final page written on the last book until it crumbles to dust. Let it go. The file was recorded using a mid/side stereo technique at 24bits, downsampled to 16bits under the loving care of gaussian dither. The room was treated as best i could to be acoustically pleasing and quiet. I think you will find the noise floor to be particularly well balanced and textured, suitable for post-production tasks, or just for relaxing with at home. .

We develop iphone app that perform musical analysis on recorded audio from the iphone. Our app implementation make use of the audio queue service to receive raw audio buffers from the audio queue callback. In the first version of our app we had the problem of too much clipping on the recording which degrade the accuracy of our analysis. We also suspected that the noise canceling algorithm in iphone 5 produce distorted sound, which is not much noticeable by human ear but distorted enough to affect our sensitive algorithm. We found that the solution to our problem is to set the audio session mode to kaudiosessionmode_measurement. This session mode is supposed to give maximum freedom for us to control the microphone input, which include turning off the automatic gain control and probably noise canceling as well. The solution works very well except that it introduce a strange waveform pattern in the beginning of all recordings in iphone 5. It is very hard to explain the waveform we get, so i made two recordings at freesound so that you can see it visually. The first recording is made in an almost quite environment, and you can see the weird spike in the beginning of the recording. The second recording (this recording) is made with constant background noise, and you can see that the actual sound wave is offset from the strange curve and gradually increase to its original volume. This waveform only happens on iphone 5 devices that we tested, and there is no problem at all for iphone 4s and older generations. We have tried various settings and the glitch is still unavoidable as long as we set the audio session mode to kaudiosessionmode_measurement. We also find similar glitch in one of our iphone 5 devices, in which the glitch happens even if we try to set just the input gain level without changing the session mode. We are not sure if this is a hardware-related bug in iphone 5, or if it is fixable software glitch in the future version of ios. For the moment we are looking for workaround that can avoid this glitch while automatic gain control and noise canceling are disabled.

Calm ambient track. Winter woods / pinewood february 12. 41 pm (noon) in the netherlands near village giersbergen. Bram’s admin request-text and my answer in audio. Hello freesounders,it happens very infrequently that i post requests. However, i have an extraordinary sad reason to do so today. I don't want to go into detail in this public forum, but someone incredibly important and incredibly young in my life and my wife's just passed away. I am thus looking for an extra long recording of a peaceful "forrest ambience" to play during the good-bye ceremony. Something with some birds and perhaps some wind through the leaves,. . . . Currently the ceremony is planned for april 6th so i would need this before then. I know i can look through freesound, but i would like something specifically recorded with this in mind, something we will be able to listen to later as well, remembering this important and sad time in our life. . . Yours in grief,- bram & familywhat you hear;general-noise; soft wind in woods, sometime a bit increasing. A far kid at the edge of hamlet giersbergen. Far hum of the woods.

More recordings here search: giersbergen. About the area, national park loonse en drunense duinen. (text by irma de potter,ranger of this area) dutch website: https://www. Natuurmonumenten. Nl/natuurgebieden/nationaal-park-loonse-en-drunense-duinen. In the loonse en drunense duinen you will find forest, heathland and especially a lot of sand. It is one of the largest shifting sand areas in western europe. The wind can blow undisturbed in many places, resulting in an ever-changing landscape. By purchasing it in 1921, it has been protected for 100 years and we can still enjoy this brabant sahara today. You can roam freely on the sand plain. So there is plenty of room to explore extensively. Marvel at the submerged trees, enjoy the chirping field crickets and quench your thirst at one of the many cafes or restaurants on the edge of this nature reserve. Walking, cycling or on horseback: it's all possible here. With the wind in your hair and the sand in your shoes. You may even come across the sheep herd. The sheep keep the heath short and eat away saplings. This is how they keep the area open. The loonse en drunense duinen still has 270 hectares of shifting sand. That sand creates rather extreme conditions: the soil is dry and nutrient-poor. The difference in temperature between day and night can be as much as 50 degrees celsius. This ensures a unique flora and fauna. The animals and plants have adapted or feel at home in drought, aridity and temperature fluctuations. Sand sedge and various lichens, for example. And the viviparous lizard, sandpit beetles and sand bees. All species that love sand. In the last ice age, the polar winds blew sand from the north to brabant, where it remained in thick packages. For a long time this sandy plain was covered with primeval forests. Until the fourteenth century the trees were felled by people. They used the wood as fuel. The bare plain was filled with heather, where the farmers grazed their cattle. This intensive grazing and the sod cutting of the soil depleted the soil. This gave the sand free play. For a long time, the sand was a major problem for the residents. Villages and fields threatened to disappear under it. Trees were planted to stop the advancing sand. You can still see the traces of this today: find the submerged trees that only peak above the sand hills with their crowns. Date/time: february 15th tuesday 2017, start 12. 44 pm.

88 piano keys, long natural reverb: up to 13 seconds per note. This is me giving back. I love freesound. You guys saved my bacon back in the day. Recently i searched for free piano notes for a game i'm making, but the only ones i could find ended too quickly. I need long reverb! luckily i have an old piano, so i made my own. So this is me giving back. This is an old piano!!!. We had the piano tuned a year ago, but it is well over 60 years old, so be warned! these notes have character! if you want perfect tone, either edit them individually, generate something artificially, or buy a professional set. But if you want a piano with personality, this is for you. Being an old piano, it only has 85 keys. So i created the highest 3 notes by speeding up previous notes, to make the modern standard 88 keys. How the notes were created. The notes are created on an old (well over 50 years) steinhoff upright piano. It only has 85 keys, so i faked the highest 3 keys by taking previous keys and changing their pitch. I opened the top, balanced my trusty everesta bm-800 condenser microphone across the top near the high note end, and held down the "loud" pedal. Each note was then hit and kept pressed down until i could no longer hear any reverb. Notes were saved as mp3 using my laptop, using free sound recorder on the highest quality settings. Yeah, i know it isn't flac, but i am strictly amateur with budget to match, and that was the best i could do. After that, all editing was of course uncomopressed until the final save. How the notes were edited. Editing was kept to a minimum, mainly to enhance the reverberation. All editing took place on audacity on linux mint. First i cropped any silence from the start. Next, used the envelope function to gradually increae volume to 200% over a couple of seconds. That is, the quietest part of the reverb is twice as loud as you might expect. Because for my game i sometimes need a single piano key to last ten seconds. Next i maximised the volume. If there was just a single stray waveform that stuck out then i reduced that by 2db or so then maximised again. Because like i said, i want to hear that reverb! i then found the part where background noise starts to be noticeable, and faded out over 1 second or so. This meant that the lowest notes had as much as 13 seconds of reverb, whereas the highest notes might only have 2 or so. Finally i checked the result, and edited three or four notes that i felt were just too ugly (badly tuned, or for some reason the software suddenly got hissy when the note became too quiet. Weird. ) i also slightly changed the pitch of a couple of notes that were slightly out of tune but otherwise ok. No doubt a better ear than mine could teak all of the notes. But as i said, it's an old piano and we're keeping it real. Finally, files were compressed to ogg at the highest quality setting, using soundkonverter. Why not flac?. I live in the countryside with very slow broadband, so i apologise for including more of the original files. But as it was, uploading this zip file took about an hour. Enjoy. Legal. Use this for anything you want, commercial or not, credit me or not. Consider it public domain. My main concern is that i had completely legal sound for my game, with nice long reverb and character. Uploading it here provides proof that i created it first, just in case anybody comes back and says "those are mine" (it happens).

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.
