1,304 Royalty-Free Audio Tracks for "Leaves"

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.

This is a collection of "small room reverb" impulse responses that i sampled in a new england home known as butternut lodge, built and owned by actress bette davis back in 1940. It consists of all wooden rooms with many non-parallel surfaces, rugs and furniture and includes 3 round-shaped "silo" rooms! these rooms sound clean and do not have the irritating "ping" of many rectangular rooms. Short history/pictures of butternut (https://www. Airbnb. Com/rooms/24692769?source_impression_id=p3_1659215694_liuasyfxoceab5fn). Although these round shapes (and some of the other very small rooms) could potentially wreak havoc with phase at specific frequencies when summed to mono, i recorded this using the mid/side mic technique; therefore, the "side" channels fully cancel out, leaving a clean monaural reverb signal. These irs are stored as flac files. They can be used directly by any daw without conversion and have the added feature of being id3 tagged with a photo of the room each ir is taken from. After downloading, select view -> large icons in the folder to view the rooms. I sampled each room using a swept sine wave into a jbl flip 6 bluetooth speaker; recorded through a tascam tm-st1 m/s stereo microphone, feeding a tascam dr-07 recorder @ 24-bits 44. 1 khz and deconvolved using reaper. As of this post, i've been using these rooms for about 2 weeks. So far, i've found the "garage" to sound fantastic on drums! the drum sound! also, many of the other smaller rooms have a great effect on guitars, keys, and hand percussion. Each room varies in tone and brightness, so i've found that selecting/tuning the reverb send works well if approached like an eq. Increase the effect send until the instrument "feels" right (then perhaps back off slightly). A close-miked acoustic guitar, for instance, will take on a nice brightness and 3-d quality; not particularly reverberant, just big. At that point, i recommend applying any eq, compression, and bigger-sounding reverb effects. Hopefully you enjoy this. Please let me know how you like it and if you have any suggestions. Cheers!.

This is a sci-fi ambient drone sound i made. It's creative commons cc0, so please treat it as public domain. You can use it in any commercial or non-commercial media for free, no restrictions. For those curious how i made this, i took a quick 8-second drum loop from my pocket operator po-33 (ko) and ran it through a free time-stretching/pitch-shifting program called akaizer. The program's based on old samplers like the akai s1000 that had extremely artifact-heavy time-stretching and pitch-shifting features. If you slow a sound down enough, the final product tends to sound harsh and electric. Akaizer turned my 8-second drum loop into 2 minutes and 38 seconds of harsh, bassy noise, pretty damn close to the final. Then i imported the file (we'll call it file a) into reaper, my daw. Track 1 has reaeq with a high-shelf acting like a low-pass. Its curve is set at 1386. 2 hz, gain at -inf, and bandwidth at 2. In retrospect, i have no idea why i didn't use a low-pass. Track 1 has a send to a blank track 2, which has a fab-filter pro-q 3 high-pass filter with a 12db slope. It's at 320. 57hz, q is 1. 096. After the eq, track 2 has valhalla shimmer set to the black hole preset with no changes. Track 3 is the default file a with valhalla shimmer on the black hole setting, but with two tweaks. Low-cut is at 30hz, high-cut is at 6630hz. Everything else is the same. That's followed by fab-filter pro-q 3 with these eq settings:-0. 72db at 69. 463hz, q at 1. 007. -1. 11db at 536. 64hz, q at 1. 013, dynamic eq (click "make dynamic" and leave everything as-is). The point of this dynamic eq is to give a slight drop in gain in the 500hz region, which tends to get muddy in larger mixes. I wasn't sure if i'd use this for a larger project, and i didn't want build-up in that region from the already large-sounding track 1 and 2. The ocassional eq drops here also adds a warble to the final mix that helps sell an analog, electrical sound. +0. 85db at 3697. 3hz, q at 1. 009. This is to add subtle airiness to the drone. It seems weird to have "airiness" in the 3-4k region, but it's the sort of rumbliness of the sound traveling away and dissipating in the atmosphere after the lowest drone sounds. My volume fader settings for all 3 tracks:. Track 1: -8. 59 dbtrack 2: -6. 46 dbtrack 3: -6. 43 db. On my master bus, i have izotope imager 9 with these settings:. Band 1: width at -100 (mono) for 59hz and below. Band 2: nothing at 60hz to 525hz (width at 0). Band 3: width at 48. 1 for 526 to 1. 4khz. Band 4: width at 49. 4 at 1. 4khz and above. Stereoize is set to 6. 4ms on mode i. And that's it! no compressors or limiters anywhere, since i liked how dynamic the actual tracks were and i figure you can always add your own compressor or limiter to the final if you want. I've also added the original po-33 drum loop on my page, as well as the loop after it was run through akaizer but before it hit reaper in case you want to do your own processing. Enjoy :).

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. . .

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.
