Recording of rain in a small town with some thunder, cars and birds. Plane passing by in the sky. Recorded with sound devices mix-pre-6 ii and two mxl 603s mogami custom mics in din stereo. Recorded in 192khz/32bit. Post editing with rx8: low/high cut with eq to reduce rumble and noise, also gain increased and cut to length. Converted to 320kbps/cbr mp3.

Recorded inside a closet. Low noise, not much reverb. Sounds almost machine-like with a satisfying thump. Recorded on a phone. I messed around with it to get it to sound nice. In case you do something that mixes the channels: on the opening part i copied a 5khz to 8. 5khz band from the left to the right channel, so that frequency band is mono.

This sound was created as follows:. -zynaddsubfx free (and insanely amazing) software synthesizer generated simple g tone using a sine-wave adsynth engine- creative sbs 250 speakers played it back distorting the sound naturally and adding some interesting stereo phasing effects (is that caused by analog signal cable being longer for one speaker?)- i was manually changing the volume using the speaker's potentiometer (whitch is dirty and added some interesting noises on the right speaker, and also at peak loudness during the 54th second the right speaker is quiet)- the output was captured by zoom h2's rear mics- and recorded via usb into audacity free audio editing program- i exported the recording as 16-bit flac.

Gravação em estúdio, utilizado microfone condensador, de um balão esvaziando. Gravado para a disciplina de captação e edição de áudio do curso rádio, tv e internet, universidade anhembi morumbi.

Recorded for discipline of capture and editing of audio - course: radio, tv and internet. Universidade anhembi morumbi. São paulo - sp. Brazil.

Nyc subway train arrives, doors open, announcement of direction, doors close, train departs. I stood on the platform at the montrose l station with a sony minidisc and recorded the entire process of a nyc subway train coming and going. Low noise, though you may wish to use a high-pass filter as there is so much bass in the material.

Synthesized drone. Created using the electribe 2 with its synth engine. Post-processing was done in cubase. More stuff in a similar vein:http://freesound.

A marimba note being struck while thrown in to the air. Can't remember the mic that was used but it was a condensor mic. This was recorded in my room so unfortunately the signal to ambient noise ratio isn't great. The sound can be used for free (though it would be great to hear about what you do with it). It may not be re-distributed as it is, or as part of a compiled sound library.

I combined an ambient bar crowd recording that i found here with a funky little back beat that i also found on this site and made a great cubicle noise blocker / filter. I use this at work with headphones on when i'm trying to concentrate and drown out conversations in the office. Also good for when i work from home and i'm trying to drown out the tv and other distractions. The crowd noise is excellent at diffusing regular office conversation and the little funky back beat keeps the crowd noise from getting boring. This works really well even at fairly low volume i. E. You dont have to crank it loud to drown out the distractions. Hope you like it and thanks to everyone for the great sounds on this site. Combination of the following two files - yet another bar crowd - june 2007. Wav (lonemonk)hip hop. Wav(ls)ps - i purposely let the crowd noise run out for a few seconds at the end so that you can appreciate the full groove of the hip hop. Wav. Has a nice effect when you loop the whole thing, gives you a little break from the crowd noise. Almost like you're stepping out of the room for a second.

Snippets from recordings of me playing the tanpura. The strings are tuned to b, d, g and e, so would work well in the keys of g or e minor. I noticed that my first pack of tanpura samples has a bit of fuzzy white noise so in this pack i have equalized - i reduced all the very high frequencies which got rid of most of the white noise without affecting the low frequency sounds of the tanpura itself. Please note this is the tanpura part of an instrument called the swar sangam which combines the swarmandal (indian harp) and the tanpura, it is not a traditional tanpura and does sound slightly different.

Recording of sea undertow on the beach of formicoli, vibo valentia, calabria, italy, the 19th agust 2022 16:44. The sound was recorder with a zoom h1n with windshield at a short distance from the crashing of the waves on the beach. The waves are driven by a light, gentle wind. The sound was recorded by holding the microphone in my hand while i dived knee-deep into the water and walk, filming the crashing of the waves (also on my legs). High-frequency sound details (the foam of the sea, the impact of waves on each other, etc. ) are much more audible here. Processing:* volume adjustment;* 120hz high pass filter (to reduce low some low frequencies rumble due to the wind);* cut and crossfade to eliminate very few mechanical noise of my hand on the mic;.

Recorded inside of an abandoned building next to a boarded-up, old wooden exit door. Has a nice, subtle low hum, which is actually from a plane flying overhead. Also contains knocking sounds, which is most likely the door being a bit loose. Would be awesome for horror atmospheres. Feel free to use this sound for what ever you wish to. Credit is appreciated but not needed. Let me know what you use this sound for!.

Oddly enough this man does not consider himself a baritone, and his speaking voice is not so deep. This was not modified except with noise reduction, because the air conditioning was audible. It just happens to be the deepest sound i've ever heard him make, and he wasn't awake. So it wasn't a moan, or a groan, or a gasp. Please tell me what you think it is. I called it an exhale, and yeah, i don't think grizzlies typically go this low.

Field recording of a summer afternoon (28th june, ~20:30) in berlin lichtenberg. The recorder (edirol r-09rh) was set in a very high building, therefore the sound consists mainly of ambient noise, eventually with subtle concrete sounds (birds, childs, dogs, sirens,. . . ). The audio is unfiltered, so it's dominated by low-frequency energy. Filter as you wish :). (the web preview seems to have some high frequency artifacts. Download the wav file to get it on full quality).

A tense but pretty still athmosphere created with a number of tools by me. Got some subtle movement in it and consists of several major parts. If you need a particular section of it, then use volume, proximity vst and reverb automation to smooth edges out. You can listen to my music at http://vospi. Com/.

A second attempt at recording the deep mud i keep finding myself walking through each morning on walthamstow marshes. This recording was made using a sound devices mixpre6ii and a stereo pair of fel em172 mics (connected to a bent wire clothes hanger and positioned about 30cm above my feet). Processing: normalize -1. 0db, low cut filter 100hz, minor noise reduction to reduce background traffic/train noise. I do not require any credit or attribution.

This is a percussion beats made at tempo 124. It spans 8 bars and is ready to be looped in your daw. This is a sound i've found in my old foxdot projects, it has a really cool "ocean" or "wave" noise-like sound that repeats at the right then left of stereo, in the end of each 4-bar segement. It layers multiple kicks and snares, with one of the sounds being stretched, that produce this "wave" sound. It can be evaluated in foxdot with the following code to replicate this result. D1 >> play(p[" [--]o h: -"]. Layer("mirror"),dur=pdur(5,8), rate=expvar([0. 09,2],8),sample=2, pan=sinvar([-1,1],16),amplify=0. 5).

Trying to start a 1983 volvo 245 after a stop at a gas station. First we hear the seatbelt warning signal after the driver turns the ignition on. The first start attempt fails. The two following attempts fail because the starter fails to engage with the flywheel, creating a very loud and unpleasant sound. There is some reverberation from the metal roof of the gas station. At 00:24, the driver remarks "he's doing it again!". The fourth attempt succeeds in starting the engine after a rather long cranking. We then drive off and we also hear some squeaking from the steering wheel. Throughout the recording we hear breathing noises from the driver (80 year old man, smoker). The recording was made in the front passanger seat with the window open, that's why there a very noticable difference between the left and right channel. Recorder: edirol r-09, 48khz wave/24-bit, cropped with cool edit pro, re-saved as 48khz wave/24-bit and compressed with flac. No other pp. Edirol r-09 settings: low cut: off, mic gain: low, agc: off. Recorded on june 15, 2012 in åkersberga, sweden.

(edit of other recording, with eq, reverb etc. ) recorded inside of an abandoned building next to a boarded-up, old wooden exit door. Has a nice, subtle low hum, which is actually from a plane flying overhead. Also contains knocking sounds, which is most likely the door being a bit loose. Would be awesome for horror atmospheres.

Underwater [loop] amb. Update: i have decided to release this sfx for free, public domain. Enjoy! :). Please like and share!. A loop-able ambiance of being submerged in water for your underwater needs. This one was particularly difficult to process as i had to layer many scuba diving sounds in one order to get this effect. Only after crushing many frequencies via eq, is when it gets this deep. Get it? deep like an ocean? no? okay i swim away now. . . Enjoy =). - noise reduction- high pass at 30khz- artifact removal- noise removal- bass enhancement- low pass- layering- stereo imaging- stereo widening. Details:. - gopro hero 4- 48khz- 24bit- wav.

Soundscape of a city street in chicago during winter. Sunday, january 31st 2016 at 6:05pm. Continual planes, trains, and cars passing. Occasional pedestrians. Cta "l" trains audible at the nearby thorndale red line stop. Mic: core sound tetramicrecorder: zoom f8. Converted to b format using vvtetravst, then processed to stereo as wide cardioids at + and - 45 degrees using ambisonics toolkit (atk). Light noise reduction applied using izotope rx 7 spectral de-noise. High pass filter applied to reduce low end rumble. Some editing done to remove wind buffeting. Please note that this is a 48k 24bit flac file - flac files can be easily read and converted by audacity [https://www. Audacityteam. Org/] and reaper [http://reaper. Fm/], among others.

A short recording of construction work on a ten-storey apartment building in the blackhorse road area of walthamstow, london. General construction noises. This recording was made using a sound devices mixpre6ii and a stereo pair of fel em172 mics. Low cut on the sd which in basic mode is 80hz (i think). There is some processing to this recording to ‘normalize’ the levels and light eq-ing. I do not require any credit or attribution. If any of these sounds have been of help, and you are feeling charitable, please do consider donating to freesound to help keep the site running (a link is also on the home page).

I tried and tried and tried to find a genuine audio recording of a sandstorm, but all i could find were synthetic mixes. What genuine audio i did find always had some other noise or voice polluting the audio. So, i found a couple of great wind audio recordings, some wind rustling a dry corn field, and some low earth rumbling and combined all of that to create the closet approximation i could to the authentic sandstorm audio i was able to find but couldn't use. I hope others find this audio useful in any of your projects. Feel free to use with no worries.

Automated/computer controlled plasma cutting torch. Re-processed from open source wikipedia video courtesy of metaveld wijchen bv. Noise reduced, dynamics compressed and high/low frequencies resynthesized. I'm not that big a stickler about receiving credit for the use of my sounds on freesound. As a courtesy, i appreciate it but i do ask people to always credit freesound. Org and if their project ever sees any kind of profit to please consider making a donation to the website. It's a great resource and deserves our support. Good luck with your project.

Interesting (but painful) sounds made with a zoom h2 (front mics, low gain) connected to a laptop via usb. The signal was piped to old creative sbs250 spekers with 16ms of latency (i'm using jack audio connection kit and linux). That's how my feedback loop came into existance. I turned up the volume and started to move the mics around, geting a lot of different sounds ranginf from simple tones to strange lfoish sounds. The sound touches 0db one times, but is rather undistorted (at least digitally). Recorded with audacity @ 48khz/16-bit and saved as flac.

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.

A hot summers day in the deep swedish forest. Recorded with zoom h5 with two dpa 4060 mounted in a ab stereo fashion. Birds chatting and bugs flying by is major elements in this field recording. Decided not to remove to much of the bugs in post because i felt it might suck out the soul of the recording. In post: in pro tools i removed some low rumble, and and trimmed the highs just a little bit. Added a "pro expander" to lower some noise, both generated by the h5 and the location. Hope you like it.

This sound was recorded via the use of a behringer b2 microphone, fostex fr2 and a home made parabolic reflector made from a tv satellite dish. The source of the sound was between 100m-200m away from the microphone. This has been eq'ed with high-end shelving to reduce gain noise, low-end shelved up to 1khz (to reduce wind and background noise) and the overall gain has been increased. The bird sound on the recording, is a bird called a "nightjar" which is a nocturnal bird. If you are interested in the build of the reflector itself, i have documented it here: https://www. Youtube. Com/watch?v=jyssecw1qf0. This sound is also available to listen to on my soundcloud: https://soundcloud. Com/jonmacmusicproduction. If you use my sound in any productions could you please put a link to my free sound, sound cloud or youtube channel so it can reach others!. Thanks for listening and downloading.

Registro de baja fidelidad, realizado a medio camino entre el cuarto de máquinas de un conjunto residencial ubicado en el norte de la ciudad de cali, colombia y el cuarto de descanso de trabajadores de oficios varios del mencionado conjunto, el día martes 28 de abril entre 6:30 y 7:00 a. M. Dispositivo y programa de grabación: celular huawei p20 lite + lexis audio editor. Low-fidelity recording, captured halfway between the boiler room and the workers rest area of a residential complex located in cali, colombia, on tuesday, april 28th, between 7:20 and 7:25 a. M.

Some cafe ambience severely altered with blok modular fx. Was originally a long jam cut up into a bunch of individual files but i figured searching through them would be a pain so i merged them back into one file. So listen through and pick the sounds you like with a wav editor, or enjoy it in its own regard as abstract sound sculpture or something. I don't want to divulge too much of what the patch looked like but it random note values with each keyboard press which were then ran through a waveshaper. Later on i add some reverb and use various things to alter the panning for some strange stereo effects. Edit: you might want to use a dc eliminator on the samples because the waveshaper creates some dc offset (basically useless low/zero frequency noise for those not in the know). But maybe it has some aesthetic value for you to keep it intact? you decide. Http://www. Meldaproduction. Com/plugins/product. Php?id=mutility this free vst has a dc eliminator included.

Here in the midwest we were treated to a nice preview of autumn here in the northern hemisphere. Both the temperature and humidity were nicely lower than usual and this soundscape was recorded featuring the beautiful northern breezes and a few of the birds that still live here. Since this ambience was recorded during the work-week, there are hardly any man-made internal combustion engine noises. Just the wind lifting and swirling through the tired forest and the blue jays, crows and insects. Recording made at 2:30pm on september 13 2022. Equipment used: recorder-sound devices 702microphones- left channel- sennheiser mkh 416right channel - sennheiser mkh 8070. The right channel, the very low-noise direction shotgun microphone, was pointed just about straight up at the leaves and branches of a huge cottonwood tree whose dry leaves were putting on a show. Hope you can hear this. Recorded and edited in stereo so either good studio monitors or headphones will make you feel you are in the forest surrounded by the gentle breezes swirling through oaks and cottonwood trees and insects and birds.

This is the second version without the mechanical bolt. Maybe can be used for bolt action rifles. Made this is ableton live, it is multilayered with the top end of a 9mm and the low/mid range of an ak47. Another carbine sound is faded in after the transients to give more sustain. Two reverbs fade in and out creating a smooth transition and blend. A little white noise is added for subtle sheen and air. All the layers were grouped together into a single band compressor and ran through serum fx distortion and then into a krush distortion plugin for added fatness. A blending reverb was used to glue the sounds into the same space and ran into a final transient designer which is adding a little more snap and punch and clipping the excess transients off. Enjoy.

A rather lengthy sound byte that i heavily edited to the point of being unrecognizable. It sustains a flat note with varying bass levels causing an unnerving effect or the listener or player. I had designed this track for a roleplay plot involving a cursed train station, the plot came out kinda rough and it fell through midway. . . But, the audio track i made came out good enough to post here like my first sound involving my transformers oc!. It's free to use as long as you credit me, and it can be used in a wide variety of fields that is deemed appropriate. From suspense to horror, or even background noise in a lighter field; it can be altered and edited as needed due to it's broad and simple design. I made the volume low to prevent any extreme bass causing ear bleeds. Hope you enjoy! <3.

A complete trip on métro (subway) line 9 of the paris subway system, from the alma-marceau station to the havre-caumartin station. Starts with descent into the métro station and ends climbing up the steps back out at the destination. One train is allowed to pass, at about the 1-minute mark, as we wait on the platform, and an announcement giving the times for the next trains can be heard. The ride on the following train begins at around the 2-minute mark. There are two loud sounds between about 9:10 and 9:20 and some loud low-frequency wind noise at around 10:40 (as we leave the métro station and return outside), so beware. Recording with zoom h4n, originally 96 khz/24 bits, uploaded as mp3 320 kbps because the wav was so big (almost 500 mb).

A hot summer afternoon in the swedish forest/mountains. Recorded with zoom h5 (xy) outside the cabin i rented. Recording mostly consists of birds and general life from people moving/talking as they arrive to their cabins with family. Its intended to represent a peaceful vibe with some human presence. I decided to not remove much movement/actions from the people such post because i felt it might suck out the soul of the recording. In post: in pro tools i removed some low rumble, and and trimmed the highs just a little bit. Added a "pro expander" to lower some noise, both generated by the h5 and the location. Ps. I have a version with 2 dpa 4060 in a ab stereo fashion of the same recording, abit noisy but its on my profile if you want to listen. Hope you like it.

A walk through ridley road market in dalston, east london. Lots of people chatting and music playing. As with many markets in london there are lots of languages being spoken. You can hear traders calling out what they're selling. This recording was made using a sound devices mixpre6ii and a stereo pair of fel em172 mics. Low cut on the sd which in basic mode is 80hz (i think). There is some processing to this recording to ‘normalize’ the levels and light eq-ing. I do not require any credit or attribution.

(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. 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 beautiful swimming pool and hot tub. I'm done in the hot tub and walking up 3 flights of stairs to my apartment. Squeak. . . Squeak. . . Squeak. . . Sure to sound either intimidating or goofy. Depends on your show!. I kept the peaks very low to maintain a natural sound. Recorded on 11/20/2018 in burbank, ca. Enjoy!. Christopher c. Courter.

This sounds as if it were staged by hollywood, but it actually did happen, i swear! birds chirp away to set the scene, but a beefy thunder roll intrudes. Soon after, raindrops begin to fall as if on cue. Theres a little handling noise click in the begining that is easy to crop out if you like. The recording is unedited. At 1:35 i move the mics closer to the deck so you can hear the splashing. At about at 3:10 i you’ll hear a different timbre as i move away from the rain and under an awning. About 3:45 the rain settles down and the birds start chirping again. Hopefully there are some useful segments in here. Recorded with a dead cat on a tascam dr-05 at 48khz 24 bit, then compressed with “lame --preset insane --scale 10” to make up for the low gain i used (i was afraid a thunderclap would engage the limiter). Cheers.

This is a quick fire sound i made using qubodup's "swing 25" public domain/cc0 upload on this site. It's a bamboo stick swinging, which i layered and toyed with to get the results here. For those curious, here are the steps. * i took the file into reaper, and slowed the file's playback rate to 31% of the original. * i then duplicated the file three times, for a total of 4 tracks. * track 1 (lowish gas-burner sound):- reverb (drum-room impulse response, a medium-sounding reverb with a slight deadness to it. In free impulse loader reverberate le, stretched impulse to 150% and set attack time to 0. 218s). - eq (-8db bandpass near 200hz, rising back to 0 by the 1k mark. Low-pass applied at 5. 8khz). * track 2 (lowest of sounds, like a bassy gas-burner):- chorus effect. That's it. (specifically acon digital multiply, a free plugin, set to the "romantic" preset). * track 3 (not as low as track 2, but closer to track 2 than 1)- reverb (a large hall impulse response. No adjustments, ie. No increased attack or stretching like for track 1. ). -chorus doubler (free plugin duet, preset: "basic doubler. " same effect as if i had doubled the track and pitched one up 6 cents. ). - chorus (free plugin acon digital multiply, preset: "romantic. "). * track 4 (most flame-thrower, whooshy of tracks. )- reverb (impulse response says "hall medium," but it's a thick, even echo from start to finish. Makes the sound go from its default "whoosh" to a flamethrower noise. - chorus doubler (duet again, preset: basic doubler). - chorus (acon digital multiply, preset: "romantic. "). Master bus:. - compressor (tdr kotelnikov mastering compressor, the free successor to the tdr feedback compressor ii. Preset: punchy.

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 :).

A single cricket, low wind noises, recorded with iphone 6 in mono.

Low bass-like boom used in film. I made this for a movie i am working on and i wanted to share it! please use good speakers so you can hear it.

This is a low hum sound generated by my naturalnoisegen program. Naturalnoisegen uses several timed generators to produce complex natural noises. In this case, 500 very low frequency generators with a long period were used.
