I recorded this today (1/12/23) from atlanta, where we had a bunch of heavy rain and tornado warnings this afternoon. The radio station i recorded this from is am 750. The first part of the recording isn't very interesting, but the part where she started talking about how you can't see any tornados coming was really interesting to me. I think this would make for some really good ambience in like an environmental horror track. I decided to include the whole recording anyways in case anyone wanted it. Here's the backstory to this thingey if anyone really wants it:we were on tornado watch as i was speeding trying to get home from work, when the sirens started to go off. I had to pull into a disheveled looking parking garage, as that was the closest place i could get to. The garage only had one level, so i had no way of getting to lower ground. I sat there in my car, terrified that i might be stuck there, in a shitty parking deck, in the middle of a giant ass storm, with very little cell signal, for hours on end. I decided to turn on my radio and record it from my phone. Fortunately, i was only in there for 30 minutes, and i managed to get home after the rain cleared up a bit.

I was just going through my sounds, when i decided "hey. . . I'm gonna release this. " so here you all go! i'm really proud of how this turned out. This, as you can tell, is a deep eerie ambience loop. It can be used for anything you want. I like to leave things up to the imagination of the audience. How it was made:. Software used:-fl studio 20-harmor-harmless-fruity parametric eq 2-valhallaroom. So basically what i did was get a low pitch sawtooth waveform, put it through some effects like harmonization, a low pass filter with high resonance, a phaser, and a load of distortion. The main synth is made with harmor. (yes, this is all one synth. It just has a lot of dynamics. ) i then processed it with some eqing. What made this sound what it is would be the reverb. I put 2 layers of valhallaroom on the synth. One has a very short decay time, and gives it texture. The other gives it the atmosphere. To add some more depth, for the final touch, i layered a sub-bass underneath it. Which is just a low sine-wave with reverb on it, which i used harmless to make. I hope you enjoy this!.

I tried out some new gear and methods! more mountainside rain! a complete storm from beginning to end with swelling and then waning rainfall, occasional thunder. Ms stereo bar on mic stand projected through open second-floor window, just under the roof eaves. Recorded july 20th during one of the mid-afternoon brief intense storms we can seem to get frequently in the rocky mountain foothills beginning around june. If you were listening and wondering, the direct sound of the thunder is somewhat occluded as i believe the storm was behind the overhanging roof and house from the perspective of the microphone array. The mountainous terrain and other objects in the field reflected some of that thunderclap, as well as the exterior wall of the home, and so this is all a little bit funky.

This sound is a superposition of two records. First, i recorded a coffee machine and cut it to extract just the sound of the money that falls in. Then, i recorded the sound of keys and mix it together on audacity. I wanted to make a sound that can be repeated in a loop. So, i copied the record of the coffee machine to give a rhythm to the sound. I tried to cut the sound of the key perfectly to make a loop with the help of the option “search for crosses with zero”. Then, i added view effects. I have changed the amplification in purpose to bring out more the sound of the coffee machine. I also change the reverberation. Gradually, my sound made me think of a music in a video game that i used to play, rayman. It was difficult to describe what the sound was like, but i liked the atmosphere, so i kept it. Then, a friend told me it made him think of a frog noise, and i liked the idea. Code typologie de schaeffer : v’’précisions morphologie :sur le principe de l’écoute réduite, la morphologie du son peut-être décrite comme étant un groupe tonique car nous entendons plusieurs hauteurs. Le son peut être qualifié d’acide et éclatant. Le son paraît plutôt rugueux. Je dirais que le son est dynamique mais que l’attaque n’est pas brutale mais graduelle au moment où l’on entend le son de la machine à café. Le profil mélodique présente des variations plutôt scalaires. Pour finir on entend des hauteurs de sons parmi d’autre son.

I'm attempting to create a controllable thunderstorm for a film, and this is my first legitimate attempt. This recording consists of 4 samples of rain, and another 3 samples of rain+thunder that i recorded one afternoon. Equipment used was the inbuilt mics on a roland r-26, and a sennheiser me66 into a sound devices 702. The clips were recorded at 96khz/24-bit, and they were processed at 48khz/24-bit. For processing, i put the samples into kyma, and crossfaded for texture. The howling wind sound is an analog-style low pass filter's frequency, level, and resonance being controlled by a wacom intuos4 pen/tablet. The rain slowly swells, which was done by changing parameters of a granular reverb. The thunder was also controlled by the wacom tablet, with x, y, and z (pressure) dimensions mapped to making the thunder swell in level, density, and texture. This could have been output in surround, but i don't have that many monitors ;). This style of "rain-synthesis" can also go on indefinitely. Please let me know what you think of the quality of this track; eg, if it sounds real, if the wind sounds ridiculous, too much thunder, etc. Use this sound (wherever) if you want to, or let me know if you'd like an mp3 of this, or for it to last longer. I'd like some credit if you do use it, but it's no big deal. A blog is up explaining the method of creation here:http://www. Kylehughesaudio. Com/2/post/2013/02/tempest. Html.

A reel by scanner, aka robin rimbaud. Formatted for use in the make noise morphagene. "a mixture of abstract melodic ambient and strange processed radio stuff and ‘scanner’ style sounds which should be fun. Keeping in mind that i want people to be able to use them as easily as possible and inspired. ". Scanner (british artist robin rimbaud) traverses the experimental terrain between sound and space connecting a bewilderingly diverse array of genres. Since 1991 he has been intensely active in sonic art, producing concerts, installations and recordings, the albums mass observation (1994), delivery (1997), and the garden is full of metal (1998) hailed by critics as innovative and inspirational works of contemporary electronic music. To date he has scored 65 contemporary dance productions, including works for the london royal ballet and merce cunningham in nyc. In 2016 he installed his water drops sound work in rijeka airport in croatia, ghosts at cliveden national trust uk, and scored the world’s first ever virtual reality ballet, nightfall. He scored the hit musical comedy kirikou & karaba (2007) and narnia ballet (2015) based on the popular children’s book, philips wake-up light (2009), the re-opening of the stedelijk museum, amsterdam in 2012 and in 2018 released an app that measures the quality of soil in europe with live data with artist kasia molga. His work salles des departs is permanently installed in a working morgue in paris whilst vex house, the residential house he designed a permanent soundtrack with chance de silva architects, won the riba london award 2018. Committed to working with cutting edge practitioners he collaborated with bryan ferry, wayne macgregor, mike kelley, torres, michael nyman, steve mcqueen, laurie anderson, and hussein chalayan, amongst many others.

This is a recording of myself sleeping, beginning ~ 1:00 am local time (~ 3hrs after going to bed) on january 10th, 2020 (which i later discovered was a full moon). I was in the midst of experimenting with recording myself all night long out of curiosity, using a laptop placed near the head of my bed. This particular recording was the only anomalous one (the rest consisting mostly of just breathing or snoring with occasional sleep-talking). This ~2 hour recording has several interesting properties, which make it hard for me to believe that these sounds were actually going on while i was sleeping. On the other hand, i don't have a memory of editing this file if i did. Either way, i find it unsettling. I found the file in oct 2021 while organizing my samples. As far as i can remember, this is the original raw recording. On further inspection, i discovered that it has some additional peculiar properties that make it even harder to believe i could have made it without remembering doing so. The audio spans almost exactly 118min (7080s). There’s a frequency sweep with a cycle-length of 6480ms that repeats throughout the entire recording. Dividing the 118min by 6. 48min (60 cycles) results in 18 parts containing exactly 60 cycles and a remainder of 12 cycles. If you think you know the source of the strange sounds or if you've ever heard anything similar, please let me know in the comments or email me at storyofthelie@protonmail. Com. I collected the most interesting bits into this pack:https://freesound. Org/people/storyofthelie/packs/33653/.

I made this recording of ambient backgroud noise directly beneath the eiffel tower. The shape of the eiffel tower creates a unique acoustic environment in the vicinity of the tower, especially beneath it. You can hear a much higher level of background noise than you would hear in an open area, and the noise is unusual. The tower is made of thin pieces of iron arranged into a complex and very large lattice, which reflects and slices and dices sound in a unique way. Thus you have a high level of very even and unidentifiable background noise as noises from the ground and the platform get bounced around and distorted by the structure of the tower. This recording was made from the ground, with microphones pointed straight upwards about 2 meters off the ground. Noises from the ground travel upwards and bounce around the inside of the tower, then drift back down. There are noises in the tower itself as well, such as elevator motors and people on the platforms. The first platform, at 57 meters, is open in the center, whereas the second platform, at 116 meters, is completely closed and flat on the bottom. Wind moving through the tower also makes noise, and again the open structure of the tower changes the noise in a way that is specific to the eiffel tower. There wasn't much wind at ground level for this recording, but i don't know what the wind speed was at higher levels in the tower. Some voices in multiple languages are audible in the recording, as the area beneath the tower is awash in tourists. Recorded hand-held with a zoom h4n and a mini windjammer, using built-in mics, in stereo 96 khz / 24 bits, then converted to mp3 at 320 kbps because of the size of the file. Duration is about two minutes.

This is the audible annunciation found at all intersections with traffic lights in paris, france. It announces the condition of the traffic lights for pedestrians who are blind or with impaired vision. The annunciation is turned on by pressing a button on the traffic light pole. When the crosswalk sign is red (do not cross), the recorded annunciation is always "rouge piéton" ("red light, pedestrian"), followed by the name of the street that the crosswalk crosses (in this case "rue d'antin," the quiet side street where i recorded this). This repeats over and over until the crosswalk changes to green, at which point there is a two-second trill tone followed by a repeating bell tone. The bell tone is one bell, followed by two bells, repeated four times, followed by a very brief pause, and then the sequence is repeated again. This continues until the crosswalk changes back to red, at which point the "rouge piéton" message resumes. The annunciation continues for at least one cycle of the traffic lights and then stops, unless the button is pressed again. The audio quality of the annunciation is very poor even in real life (it sounds like a wax cylinder recording or something), and can be difficult to understand. This recording accurately captures the poor quality of the annunciation. The volume of the annunciation is also adjusted dynamically based on ambient noise, so there is a slight change in volume on this recording as the system apparently reacts to noise from traffic or something. There is a weak background noise that sounds like some sort of machine, but it wasn't coming from the traffic light and i don't know the source. The recording starts with the crosswalk red, then at about 18. 3 seconds it changes to green, then it changes back to red at about 53 seconds. A car passes at around 48 seconds. Recorded with a zoom h4n, stereo 96 khz / 24 bits, built-in mics, from about ten inches below the tiny speaker in the crosswalk sign housing.

Electro-magnetic interference from the colorino talking color identifier and light probe when held near the internal ferrite antenna on the back right of a 13-year-old boombox near the bottom of the am broadcast band, from 530 to 580 khz. You first hear the device inactive being brought near the radio. This gives a low buzz of stacato clicks. At about 00:23 the light probe button is briefly pushed, you hear a quick boop of the light probe with low light level combined with the beginning of the white noise of the device active. If you put your ear near it after you use it, you will hear a slight hiss from the audio amplifier carrier idling for about a minute after last use. On the am radio this translates to white noise. At 00:26 there is a double click and a distorted voice says black. The voice is being picked up by the am radio. 10 seconds of white noise and i press the color button again and it says black. I put something else over the color sensor and it says a few more things. At 00:51 i hold down the light probe button and try to point it at the light above my desk while still holding it close enough to the radio to pick up the emi signal. You hear a warbling tone at 00:59 as the light reaching the sensor increases and decreases in brightness depending on how it's pointed. The signal fades in and out as the device is moved around. This has all happened at 530 khz. At 01:37 i step the radio up to 580 khz where you get a stronger signal. Wibw from topeka competes with the noise throughout the rest of the file. At 01:51 you hear the distorted error beep as i press the color button without anything but air and light in front of the color sensor. It must be pressed up against the thing you want the color of, or it gets in too much ambient light and errors out with a loud protesting beep.

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.

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.

What i hear in this sound is a crashing starship as you regain consciousness surrounded by chaos of the crew and emergency systems. At 00:52 there's a really cool explosion hit that fits the starship in danger vibe. Created from roughly 230 sounds in reaper by looping, batch actions and modulated filtering. All sounds came from a folder of freesound cc0 sounds i've been collecting. Here is the file list if you are curious:. 103117__geronimo83__elephant.

guardians of limbo (spectral voices, ethereal sounds, odd vocals) sample of fx preset from magnus choir vsti software. Virtual choir (musical instrument). Software description:. Magnus choir is a vst, vst3 and audio unit virtual instrument which can be used to create natural and synthetic choirs. The male and female choruses combine to form a mixed choir, featuring the classic satb (soprano, alto, tenor, bass) structure: women sing soprano and alto, while men sing tenor and bass. Versatile to generate a wide spectrum of choirs, vocal textures, choral pads and voices with modulation capabilities for a new level of realism in digital sound creation. • 54 preset sounds ready to use, including a vast array of natural and synthetic sounds, from oohs, aahs, men and women in mixed choirs to the celestial choir of angels, reso pads, dark atmos, creepy voices, ambient ghostly and birdsong effects, as well as cinematic and soundscapes. 01. - abbey ghost02. - ad infinitum formant03. - ad libitum chorale04. - aeternus lux lucis05. - alchemical signals06. - angelic vox07. - angels between us08. - apocalyptic chamber09. - astral singers10. - aurum vox pad11. - birds sonic sweep12. - caelestis kingdom13. - celestial choir14. - choral ensemble15. - choralis pad16. - cinematic padilius17. - cosmic odyssey voice18. - cryogenic dimension19. - dark cantus20. - digital voice21. - dystopian chorus22. - elves land23. - enchanted goblins24. - ethereal voices25. - guardians of limbo26. - lost souls in the dark27. - male & female aahs28. - morph dreams29. - morphed vowels30. - mystical vowels31. - nebula dark atmos32. - necromancer summons33. - neo choir34. - octave aahs choir35. - octave vox pad36. - oniric sequences37. - oohs choir38. - psychedelic vox39. - psychomanteum reso40. - quasi spatial voices41. - relaxing paradise42. - restless spirits43. - sanctus holy chant44. - sonorous skies45. - sopranvox c4-c646. - spatiotemporal atmos47. - spectral hell48. - synthetic chorus49. - synthesized vocals50. - underworld embryos51. - vinyl chorus52. - voices in the mist53. - vowelled soundscape54. - vox vocis texture. • low frequency oscillator section: these knobs apply modulation to the selected instrument. By using the lfo to modulate various aspects of the audio signal, you can apply effects such as vibrato or tremolo. • adsr envelope generator with attack, sustain, decay and release parameters. • pitch bend: the pitch bend knob directly changes the pitch of the selected instrument. • reverb built-in: provides a spaciousness and depth to simulate the sound reflections from walls, floors and ceilings following a sound created in an acoustically reflective environment. Small rooms can be modeled as well as large spaces. • filter section: with filter type box for low pass filter and high pass filter. • amplitude range parameters: it controls the loudness, the way in which we perceive amplitude. The sensitivity level is set by the user. • panning potentiometer control. • midi cc automation: implementation of midi continuous controller parameters for use with external hardware control via daw.

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. 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.
