We went to strasbourg to follow an invitation by an photographer to his vernissage! to bad that we got stucked into the traffic jam and arrived while the gallery was already closed! that was really a bummer because the drive took us four hours!lucky that i had my zoom h6 because strasbourg is by far an amazing city with so many street life. It is insane how many little streets with these tiny cafes and all the people around! it is like a magnet and you got sucked in. The french people know how to live life and i recorded in 3 parts of the city to give you a nice ambience feeling. This is part 1.

Our neighbors fought a lot. Usually at around 2am and it would go on for about an hour or two. Besides being angry and annoyed, my girlfriend and i were always curious as to what they could possibly be fighting about. I had the idea to record them via a long mic cable stretching down the hallway, strategically hidden behind a few pieces of wood, to their apartment door. My plan was to one day play this from my stereo at a loud volume around 2am. As i later thought this through i realized that this would only disturb my other quiet neighbors and was a fairly selfish act. Anyway, i used a $100 audio-technica stereo mic and recorded it directly into my computer as an. Aiff. They seem to be arguing about a stereo and someone not loving the other. It's rather sad. We no longer live in that building so i have no idea what became of them. I hope they are happier now. Enjoy.

Where we live the fireworks laws are pretty lax so people go crazy with them. Here is a recording from the day before independence day (yesterday) as people were blowing up part of their arsenal ahead of time. In a few hours i will be recording as things get really crazy. Our neighbors on three sides will light off the thousands of dollars of fireworks that they have purchased. Many of them are illegal (purchased from indian reservations) so there will be some big booms. Back to this recording. It is recorded with my "fake head" binaural setup, hanging from a tripod at the crest of the garage roof. There is a tree a few feet away and a light breeze is rustling the leaves. Here is a bit of a timeline:. 0:00 kids across the street light off a few fireworks4:05 the neighbors across the street were having a party, and the guests begin to leave. 6:30 the guest of honor honks and yells "love you" as she drives away. 8:00 the kids across the street go inside. Now all you hear are fireworks in the distance, all over town. 32:17 someone lights what must be a million firecrackers. They continue until 51:20 - 19 minutes!!!.

This racing vehicles recording 2 track. It might be viable for use in racing and driving video games. But over the past few years, games emerged as some of the top-selling products in video and computer gaming. The main focus in such a project would be on generating a score by merging a few sounds in the background of the soundtrack (such as bumping or breaking) with specific vehicle sound effects (such as braking). Loops would be used to affect pre-composed music, using live data to change the mix and instrumental direction (such as the dynamics, texture or timbre), or even the pitch, rhythm or tempo), moreover, the musical soundtrack for racing vehicle gameplay could be stored in a memory card to use in digital sport car sounds unit that convenient sound effects according to the processes, which is essential to participate in the training driver by granting the user with more information. In real life, the driver has more sensory information.

I recently contributed a track to a triple lp set of krautrock cover versions ("head music 2", released by fruits de mer records, december 2020). The song i chose to cover was kraftwerk's "autobahn". If you know the track, you'll know that it uses synthesised traffic sounds alongside recordings of the same. On my version, i achieved these in three ways:. 1) i downloaded some public domain traffic sound effects from elsewhere here on freesound. Org (thanks, guys!). 2) i got in my car with my zoom recorder and made my own recordings of the engine starting, stopping, etc. 3) i made my own sound effects using virtual synths and effects in ableton live 10. This particular sound falls into the third category. Let me stress that while the song "autobahn" is copyrighted, these are isolated sound effects and are not covered by copyright. I'm making them available here under a public domain licence. If you download and use any of these samples, please let me know in the comments what you did with them. It's not compulsory but it would be interesting to know what people did with these sounds.

Indonesian maids singing in the park -. Every sunday in the streets and parks of hong kong - scores of maids meet up to enjoy their one day off a week -- they are temporary residents of hong kong and no matter how long they stay here for they must return home - there was a case last year of a lady who having worked here for 25 years wasnt allowed to stay. . These migrants mostly live with their chinese employers - who treat them very much like slaves, working long hard days, some of whome get to sleep on kitchen or bathroom floors. . . They arent wealthy so on their days off can't afford to go restaurants an cinemas and any way they are all here to earn money to send back to their families and children, since they cant afford much they tend to gather in groups in to dance and sing, or sit and eat play cards. I just so happened past a 'street' party in victoria park and took a recording as it sounded very exotic and all the people seemed happy in way i couldnt describe - altho i feel this recording is actually a little sad?. .

Formatted for use in the makenoise morphagene eurorack module. These live acoustic recordings i made with a sony pcm m10 around my house / farm in thailand. They concentrate on the percussive hits, scrapes, cuts, frogs, insects, water wells, metal farm things, gongs, railings, fans, crushed snail shells, creaks, dogs, drips and clicks. Useful for musique concrete artists. Https://www. Instagram. Com/p/cczmpenh1n0/?igshid=13qsz9itlxntphttps://www. Instagram. Com/p/cfb6blvhexl/?igshid=b35rj1fju85rfor morphagene users, just rename the wav file "mg1" for it to be seen. The wav file can be used in any sampler but you may not see any of the morphagene slice points - so you need to slice manually. I record music as "mudlogger" using buchla easel/200e, serge 4u and eurorack instruments and as "hoan kiem chess team" using ciat lonbarde instruments. Https://mudlogger. Bandcamp.

Pajarito it's the name of the song. What you hear are jacanas, the small traditional guitars used by jarocho's musicians, and one requinto guitar (and some kids laughing). Playing jaranas: elías meléndez, who i personally dubbed as "the muddy waters of son jarocho" -he passed away on 2017-; arturo barradas, leader of soneros del tesechoacan, a famous jarocho music band, and his son, young elías barradas. Playing the requinto guitar is adrián luna, who for many years was a member of the grammy awardees group los cojolites. Adrián luna's voice is on one song (el conejo) included in the soundtrack of the two oscars winner and internationally recognized movie frida (2002). Recorded with zoom, in 2013, in tuxtepec, oaxaca, during a jam session. Rip elías meléndez.

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.

A was busy doing some big muff basedenvelope follower, envelope filteredcomposition, when it hit me, a small portioncould be used for the max. 12 second loopof a loop exercice we're doing in the class. Here, i manipulate the envelope filter twice. First, a recorded loop, of my vintage teisco60's 70's don't remember anymore, doesn't matterguitar, i found for 90 euro at an online rommelmarktlet's say. . . I put the envelope filter so that it 'just' triggerson the peaks of my audio file. . . Oww yeah !!!. The second time i trigger the envelope filter, is wheni play live on top of the recorded loop, i'm playing on purposepercussive, a coup of my hand with an immediate attack, toeven further more let the filter open & because of the amazinggrainy low-frequency based russian sovtek big muff the filtergrowls even more. . . On top of the just percussive behavior, i playof course an harmonic, content related sequence, feeling that the loopwhile being in an odd measure, already is repeating itself , the liveplaying, contrastwise, makes variation in texture & harmonic/melodice content. . .

I guess it's what (nearly) every hongkongers would like to make it as ringtone sound for everyday life, right? #hehe#. Recorded near dolce & gabbana kowloon shop, at canton road, tsim sha tsui, hong kong, during protesting against d&g;'s "blocking esp. Hongkongers to take photos outside their shops" behaviour on 8th january, 2012. The "無綫新聞.事事但但" (tvb news, absentminded (news reporting)) is a slogan which to satirize tvb that self-filtering unwanted news for china government, or specificity, the communist party of china. Their (sometimes actually talking about yuen chi wai's, the head of the news dept. Of tvb, who interviewed with li pang after "8964" tiananmen square protests of 1989, with no following the professional conduct of journalism, and being abused as dog after the report was broadcasted) behaviour lets many hong kong network users calling them cctvb, which means they are more likely to be the hong kong mirror of cctv in china. A man even made a board wrote "無綫新聞.事事但但" and shown on camera when tvb news was doing a live report. This slogan are being called by protesters on that event as they don't like tvb reports the event like a entertainment news.

This is a submission for sarah belle reid's collaboration prompt for her forthcoming electroacoustic opera. It comprises a dry recording of a male voice reading the following original text describing a moment from a dream:. "this is a story about dreams. It is not about a specific dream, or rather while it takes place in one dream it is about many. From time to time in my dreams i am in a city. Not a particular city, like paris or chicago, but the events of the dream happen in a setting which includes tall buildings and crowded streets and views of the sun setting behind a busy skyline. One time, while having such a dream, i was standing on an arcing bridge over a body of water like a river or canal. The late afternoon sun was to my left, and the warmth of the sunlight contrasted with the cool breeze off the water. As i looked across the curving expanse of water, i was mesmerized by the bright reflections of the sun on the water, on the glass of the windows, across this expansive space. I realized with a start that i recognized a cluster of buildings across the way. I had seen them before, in another dream. In that dream i had been a different person. Rather, in most all of my dreams i am in some way myself, but entangled in a moment from some other life, surrounded by characters and pursuing concerns that are alien to my waking being. In that moment, in this dream, i came to understand that all my dreams that happen in a city are happening in the same city, the same geography and architecture holding dozens of episodic lives i may have between sleeping and waking.

A late summer soundscape that is a favorite of mine. . Microphones set up in some mature woods about 60 feet from a large lake on labor day weekend. Most of the background is the insects, which are very obvious during this time of year. The swelling of their volume is nap-inducing (*at least to me in my opinion. )here is the midwest this swelling and subsiding of the insect wave tells me that summer is just about starting to go back downhill, after a feverish peak. Despite the covid-19 of the year, nature does not seem to have changed her soundscape. Life goes on in the forests. The birds, whose job of raising young is over, are still there. . . They're just resting and relaxing and listening to the insects as well i'm sure. Now of course you will hear a few prominent birds in this captured moment:(1) a great blue heron squawks out starting at 1:17 into this piece. (2) the alarm call of a red-headed woodpecker can be heard at 2:14. Other than that, just the insects singing their hearts out and the assortment of birds taking secondary place during this time of year. This was recorded on sunday september 6th 2020 at 8:30 in the morning in the forest in southern illinois. Equipment: zoom f4, microphone: sennheiser mkh 8060. Enjoy this audio snapshot of the subdued -- yet vibrant - sound color of late summer, finding comfort in the fact that, within four weeks, the colors of the leaves will be changing to oranges and reds and yellows. But, for now, there is still life to live in the insect and bird world.

In front of my desk in my room is a wood paneled wall with a cubbie. It's about a foot wide, 10 inches from top to bottom and maybe 7 inches deep. I'm just guessing. Around this cubbie is a border of wood. In the bottom right corner under the border i have jammed one end of an elastic string that used to have glitter on it. It's from a christmas box of chocolates my uncle sent me last year. I stand in front of this cubbie whose bottom is at chin height, (i'm only 5ft1in) so my arms are above my head as i pull this string across the cubbie to the border on the left which acts as my only fret. The string is a few inches longer than the cubbie is wide, but when i pull it it gets longer so my hand is 3/4 along it's length as i pull back and forth across the border to tighten and loosen the string. No matter how hard i pull it never pops loose from it's mooring. The recording starts with me standing up from my chair. In the first part until 01:54 i am playing the string at maybe 30° from horizontal. It has a buzzy quality that reminds me of an african folk instrument i can't remember the name of. From 01:33 to 01:54 i'm trying to imitate a korean folk vibrato kind of thing. In the second part until 02:29 i am playing 45 to 60° from horizontal and it sounds like a full-bodied string bass with no buzz. In the last part beginning at 02:34 i am playing about 75° from horizontal across the top border of the cubbie on the left so it sounds buzzy and african again, and i'm just going crazy goofing around with a crazy bluesy rock sort of rhythm. There didn't seem to be any homemade 1-stringed wall-cubbie basses on this site so here is mine, have fun. I don't play it if mom is home because the living room is on the other side of the wall and she can't hear tv. Also my neighbor can probably hear it in the next apartment lol. Recorded with microsoft lifecam 3000.

Johann Sebastian Bach (1685-1750) Cantata BWV 125: Mit Fried und Freud ich fahr dahin (2 February 1725) 1. Mit Fried und Freud ich fahr dahin (Chorus) 2. Ich will auch mit gebrochnen Augen (Aria: A) 05:27 3. O Wunder, daß ein Herz (Recitative: B) 13:19 4. Ein unbegreiflich Licht erfüllt den ganzen Kreis der Erden (Duet: T, B) 15:36 5. O unerschöpfter Schatz der Güte (Recitative: A) 20:55 6. Er ist das Heil und selig Licht (Chorale) 21:37 Soloists: Alto: Ingeborg Danz Tenor: Mark Padmore Bass: Peter Kooy Performed by Collegium Vocale Gent under the direction of Philippe Herreweghe. Recorded by Harmonia Mundi France in 1998. "Bach composed the cantata 'Mit Fried und Freud' for the feast of the Purification on 2 February 1725. Here, the opening chorus is in 12/8 time, which is almost always associated with a peaceful, pastoral mood. Here it is the expressive key of E minor, which, raised to monumental heights, will re-appear in the opening chorus of the St. Matthew Passion. The chorale is sung in long note values by the soprano accompanied by the lower voices of the chorus in densely textured imitation, and which takes up the serenely elegiac movement of the instrumental ritornello theme. Only twice does Bach interrupt the pattern: at the words 'sanft und stille' all the voices drop into a sudden 'piano' and even the lively rhythm of the vocal part gives way to a more tranquil measure. The contrast of the 'forte' on the next words, 'wie Gott mir verheißen hat' is all the more convincing in relation to the preceding words. Once again Bach leads the vocal part into a quiet, even tenor for the final line of the chorale, 'der Tod ist mein Schlaf worden.'

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.

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).
