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!.

Jaroslav Jezek was born in Prague 1906 and studied at the Prague Conservatory, graduating in 1927. He studied music during the period of the new freedom with its' influence of American jazz and dance on Czech composers which can certainly be seen in Jezek's works. From '28-38, Jezek composed music for 20 plays and revues performed at the Liberated Theater where absurdities of the times-moral hypocrisy, the mistakes of democracies and the inanities of totalitarianism-especially of the Nazis, were humorously skewered. He composed waltzes, tangos, charlestons, rhumbas, and jazz for his admiring Czech audiences. During WWII he moved to New York, possibly because his past criticisms of the Nazi Party would have landed him in prison. He continued to compose there in 1939-41. He died in New York in 1942. The Bugatti Step was written to commemorate Czech racing car driver Eliska Junkova's 2nd place finish in a Swiss mountain race in '27 in her huge Bugatti touring car, seen at 2:08 in this vid. Thanks to former yt contributor KSPM who originally uploaded this music and introduced me to Jezek.

This is the soundscape i've recorded in my neighboorhood of cidade tiradentes, a district from são paulo, brazil. We name these events as pancadão (big punch) or fluxo (flow). When a flow occurs, you know that the sound is very high and it invades all surroundings. It happened in april 4, 2021, during our worst period in the the global covid-19 pandemic. Plent of people, vehicles, multiple speakers and so on in a street. I'm writing in the exact moment police came to repress, but in my conclusion only education can solve city problems, not repression, not paliative atitudes. I think this is interesting to share it here, as a cultural manifestation, showing that when the state fails, everyone fails. This is disrespectful at all, but i try to look it as a construction of city. In a country where its president goes for a for a swim at a crowded beach amid 200 thousand pandemic deaths, how can i criticize suburban people?. I'm not conservative, i like the kind of music playing known as"brazilian funk" or "funk carioca", this is our culture, even if i do not participate actively. Plot twist: i was working in a asmr video. *-*. Recorded in mp3 320 kbps, using a zoom h1n and compressed in ableton live to bring on the dynamics.

Władysław Tarnowski ps. Ernest Buława (1836-1878) opera "Achmed oder der Pilger der Liebe", „Ballet” z II Aktu, składający się z 3 cześci przeplecionych ze sobą: Khelas (taniec arabski) z Królem i [jego córką] Dolorez na tronach oraz świtą dworską, Gitana (taniec solo z kastanietami), Eros i Psyche (Oto są dwa posągi ogrodowe, budzi się najpierw Eros, opuszcza swój cokół. Budzi Psyche jednym pocałunkiem – pieszczą się w ogrodzie[;] gonitwa za motylem. Wreszcie człowiek zjawia się w ogrodzie, oni biegną szybko do cokołów i na powrót kamienieją.) [Warto tu zwrócić uwagę na obraz Artura Grottgera „Rozmowa posagów” z roku 1865, namalowany w Śniatynce – posiadłości Stanisława Tarnowskiego zwanego „Białym” przyjaciela, mecenasa i modela Artura Grottgera a rodzonego brata kompozytora Władysława Tarnowskiego, obraz wydaje się stanowić inspiracje do tej części Baletu. Stąd zilustrowanie muzyki do ostatniej części Baletu fragmentami obrazu Artura Grottgera.] Kolejność ma być wedle partytury następująca: Khelas, Gitana, (Khelas ze śpiewem tu pominietym), Gitana, Eros i Psyche – część A, Gitana, Eros i Psyche – cześć B z gonitwą za motylem. Opera ta jest oparta na opowiadaniu Washingtona Irvinga opublikowanym w "Tales of the Alhambra', autorem libretta był Wladysław Tarnowski, który także przetłumaczył opowiadanie (Powieść o księciu Ahmedzie al Kamel albo o pielgrzymie miłości.) Akcja opery dzieje się na terenie dzisiejszej Hiszpanii a głównym bohaterem jest syn władcy Grenady. Partytura: Władysław Tarnowski ps.

Wo ist doch (a cantata) by Dieterich Buxtehude, performed live by self. Text/lyrics Soprano Wo ist doch mein Freund geblieben? Will Er mich denn nicht mehr lieben? Er hat sich in dieser Nacht, da ich aus dem Schlaf erwachte und an seine Huld gedachte, aus dem Bette weggemacht. Ach ich habe den verloren, den ich einzig mir erkoren! Ach, ich habe nicht betrübt! Er ist der, der mir gefallen, darum soll mein Stimm erschallen: Soprano/Bass Schönste(r), wo befindst du dich? Soprano Hör ich doch des Freundes Worte! Ruft Er nicht an diesem Orte? Soprano/Bass Schönste(r), wo befindst du dich? Bass Du hast mir das Herz genommen, Vielgeliebte! Soprano Ich will kommen, eile fort, erfreue mich! Komm, mein Freund, in meinen Garten! Bass Willst du mich daselbst erwarten? Sieh, ich steh schon vor der Tür, sieh, ich komme, meine Taube, denn dein wohlgegründter Glaube zeucht und neigt mich hin zu dir. Soprano Wenn du unter deinem Schatten mir die Ruhe willst gestatten, dann so ist mir ewig wohl. Soprano/Bass Ich lieb dich, weil du mich liebest und dich mir zu eigen giebest. Nichts ist, das uns scheiden soll. Soprano Du bist, Schönster, meine Sonne. Bass Dir ist schon die süsse Wonne und die Ruh von mir bereit. Soprano/Bass Komm mein Schatz, lass mich dich küssen, denn so kannst du mir / kann ich dir versüssen, alles Leidens Bitterkeit. Soprano Endlich hab ich den gefunden, den ich lieb, meine Freude. Bass So ist verschwunden dir die schrekkensvolle Zeit, weil ich dein bin, meine Freude. Soprano/Bass Komm nach dem gehabten Leide hin, wo dir das Herz/ die Freud bereit. So lieben die Seele und Jesus zusammen. Sie lieben beständig, man scheidet sie nicht. Sie brennen und stehen in lieblichen Flammen, die Seele vergnügt sich in seligem Licht. Wir sehnen uns alle mit Herzens Verlangen, wann werden wir einsten dich, Jesu, umfangen?

A compilation made from a longer recording taken in my backyard on the 4th of july 2021. There are lots of pops and booms of neighborhood fireworks. I strung together what sounded like the best and got rid of longer periods of inactivity or other distracting noises. Enjoy!.

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.

(recorder: zoomh4npro 2018)(microphones: binaural roland cs-10em in-ear monitors). As these are recorded using binaural in-ear mics, i purposefully don't turn my head to keep the sound clean and coming from the same direction. Wow, this is a long one. . . But a good one. Let me set the scene for this audio because i am a nerd. . . Burbank, california. A large apartment/condominium complex with an open courtyard and a swimming pool and hot tub. Now, for some reason in la, nobody ever seems to actually use pools or hot tubs anymore so it's not hard to get clean audio. So, from beginning to end you will basically hear me turn the automatic shutoff dial on the wall, walk to the hot tub, get in the hot tub, and sit in various positions for extended periods of time. I was alone for the entire experience (wife was at work) and nobody joined. It's very clean audio and safe for all production. Recorded on 11/20/2018 in burbank, ca. Enjoy,. Christopher c. Courter.
