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.

An excerpt from the song “Au clair de la lune”, originally recorded as a phonautogram on paper. As of May 2009, this is believed to be the oldest recognizable recording of a human voice in existence. According to the remasterers, the lyrics sung are the first lines of the second stanza "Au clair de la lune, Pierrot répondit" (Under the moonlight, Pierrot replied).[1] It has also been reported that the recording contains the beginning of the song, "Au clair de la lune, mon ami Pierrot..." (Under the moonlight, my friend Pierrot...).[2] Ausschnitt aus dem Lied “Au clair de la lune”, ursprünglich als Phonautogramm auf Papier aufgezeichnet. Per 2008 gilt diese Aufzeichnung als die älteste bekannte Tonaufnahme. Die gesungenen Worte lauten: "Au clair de la lune, Pierrot répondit" (Bei des Mondes Scheine, antwortet Pierrot), oder "Au clair de la lune, mon ami Pierrot..." (Bei des Mondes Scheine, mein Freund Pierrot...). Un extrait de la chanson “Au clair de la lune”, telle qu'enregistrée sur papier sous forme de phonautogramme. À la date de mai 2009, on le considère comme le plus ancien enregistrement d'une voix humaine reconnaissable. D'après les restaurateurs, les paroles correspondent aux premières lignes de la seconde strophe : « Au clair de la lune, Pierrot répondit ».[3] D'autres estiment qu'il s'agit plutôt du début de la chanson : « Au clair de la lune, mon ami Pierrot ».[4] Čeština: Skladba Au clair de la lune (Za svitu luny), nahraná Édouardem-Léonen Scotem de Martinville v roce 1860, je považována za historicky nejstarší zvukovou nahrávku vůbec. Македонски: Песната На месечевиот сјај (Au clair de la lune) снимена од Едуар Леон Скот де Мартенвил во 1860 г. Се смета за најстарата постоечка звучна снимка во историјата. Fragment popularnej francuskiej piosenki Au clair de la lune (pol. W świetle księżyca) zarejestrowany jako fonautogram w 1860 roku przez Édouarda-Léona Scotta de Martinville'a, który uznawany jest za najstarsze istniejące nagranie ludzkiego głosu.

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.

Frequent tube riders may be familiar with the hum that happens between two stops, (i can't remember which two. ) for a moment, it gets a little too loud and freaks you out (around the 1:40 mark). The rest is just tube ambience. Recorded in stereo on a zoom h4n.

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).
