1,945 Royalty-Free Audio Tracks for "Computer"

would you get the door? i have a package coming that needs to be signed-for. . (chuckle) "sure. ". (pause) "are you dressed?" heh. Of course he changed his tune, but i was already headed for the stairs. Yep. Sure did. I didn’t step outside, though. Figured it was safer to let ‘em in…. Here’s a quick tip: when you’re holding the little computer thingie and signing, your hands are occupied. The thing kept rejecting my signature. Like, five times. Also if the package is on the floor, how you pick it up calls for considered forethought. I'd already sidestepped, um, all of that. Since when do two guys deliver one package?.

[hint_clue_trace_03. Wav]. Sounds like someone is saying "hello!", like "listen!". This could be a hint/clue!. This sound can for example be used in games, for example when the npc pops up at the player's television/computer/smartphone/tablet-screen and gives a hint/clue, for example via dialogue which says "look behind the giant, sleeping orc!" - you name it!. If you enjoyed the sound, please rate, comment, spread! it really helps!. Note: make sure to check out the other matrixxx-sounds! the sound quality is always better when you download the sound(s)! ⛄. Enjoy!/matrixxx.

Electromagnetic interference from computers.

From Die Zauberflöte, K.620 Wenn Tugend und Gerechtigkeit ... "When virtue and justice spread the path of the great with fame.." These pages contain some of my MIDI sequences of classical music in general midi (GM) format, linked so that you can download or play them by clicking on the links. The sequences are intended to be heard on a computer sound card, and do not include system exclusive messages or controllers other than volume, pan, reverb and chorus. They are all in the public domain. That is, they are no-one's intellectual property: they may be freely copied, adapted, tinkered with and, I hope, surpassed by others.

This is the sound of a spaceship's underbelly cargo hatch closing mid-flight after receiving a cargo transfer. The sequence begins with a warning alarm indicating the hatch closing, followed by the sound of the giant servos rotating the dual bay doors up and inward until the bay is sealed shut and locked. An all clear signal is given, reverberating into the dark, silent chamber. Made in logic pro, completely synthesized with es2 and mac's built in speech synthesis for vocal alarm. No unoriginal samples or sounds were used in the creation of this sound. Use freely as desired, but i would appreciate credit.

I made a small python program that generates 20 random beeps. I record the outcome. I cut the result so that the first beep starts after 0. 01 secthe file ends right after the last beep. (i'm a python noob. . . If you find something you don’t like in the code please let me know. ). In this sound i have joined three "beep files". Sound 1 panned to the leftsound 2 in the centersound 3 panned to the right. # gis_sweden 20170531 - random beep in python :-)import winsoundimport randomimport timebeepnr = 1. While beepnr < 21:freq = random. Randrange(1000)+110dur1 = random. Randrange(700)+20dur2 = random. Randrange(10)+2winsound. Beep (freq, dur1)time. Sleep(dur2/10)print 'beep number', beepnrbeepnr = beepnr + 1.

Made from taking two large atx (the form factor, the chassis) computer panels (that i havent used in quite some time), rubbing the entirety of them together quite brashly (one is on the ground), keeping the recorder on xy setup in my other hand in unison then dropping them onto each other. Inside of reaper, i begin changing the rate and pitching them down and applied saturation, distortion and reverberation gave them a very clean effect of a decrepit gate shutting down. Good for trapping your enemies in a battle to the death for which the title is inspired from; one of those tension moments a person in a film/game finds themselves in.

All those sounds are actually made by an acer aspire 3000.

I was fooling around with audacity and created this neat little sound. I have no clue how to lower the volume, and really, i mean it: this thing is loud. I keep my volume at 10% and i couldn't even listen to this thing with my headphones. I have tried to lower the volume (so that it doesn't hurt the ears) but to no avail. If you by chance know how (in audacity) then feel free to tell me in the comments and i'll re-upload a non-deafening version. If you use it i don't mind at all, though i am curious, if you do use it, what you'll use it for. Either way, i don't mind, but i'm curious by nature.

Bird singing recorded at around 3:40 am with yinger bm 800 ldc-microphone in front of my open window, i had to add some noise reduction because of my computer fan with reafir (there isn't really much of that noise left, atleast if compared to original). You can also maybe hear ocassional space bar-click sound maybe twice, but it's still pretty useable clip in my opinion, i recorded this just to test my new microphone, and because i couldn't sleep because of the loud birds singing, and in revenge i recorded that with my shiny new yinger bm800. You are free to use this soundclip for both commercial and non-commercial audio and video work. File format: 16 bit/44. 1khz mono. Wav-file.

Idea for a base for a radio bumper. I found another track in which someone had said, "du bist der hörer. Wir sind das radio. " so i recorded myself repeating these sentences, which translate from german into english as, "you are the listener. We are the radio. " i also overlaid it over a track of generated sine waves, one in each channel (l-r), chosen to be discordant (like a radioactive effect). Sine waves are 10. 5 seconds, i left 4. 5 seconds at the end to overlay your content (maybe an ident or whatever). Have fun!. Created for my online radio station (sscr tampa), but released in the public domain/creative commons zero/"copyleft" to the maximum extent allowed by law. Voice is my own, tones generated on my computer.

This is my recording of a typewriter typing.

Ambient sound akin to the bridge of a starship. Muted background hum with an overtone of air conditioning ducts. Pseudo-random high pitched blips occupy the soundstage. Could be used as an ambient sound loop for hi-tech / science fiction interiors such as a laboratory, a control room, or the bridge of a spacecraft. Created with two instances of flstudio 3x osc. One kicking out a pair of sinewaves plus noise for the background susurus (hum) and ventilation sound. Second 3x osc is set to produce two interfereing square waves for the blips, squeaks and buzzes. The background was notch filtered and bandpassed to mellow out the humming sound and reduce hiss. The blips were processed with flstudio equo, stereo enhance, fruity delay2 and fl pan-o-matic vst. Each blip was pasted by hand in a seemingly random but not too unpleasant pattern.

This is a precise emulation of the audible time signal broadcast by radio station wwv of the nist in the usa on shortwave. This recording was produced via a program i wrote that emulates the time signal and recreates it from scratch, but it conforms precisely to the specs of the real signal. The only part missing is the voice announcement of the time, which, in the real broadcast, is made during the last fifteen seconds of each minute (which is why the tone changes to just clicks during that time). There are two minutes in the recording, but it should be easy to loop it or otherwise modify it for other durations. Since this audio file was computer-generated from scratch, it contains no noise, but the real broadcast has some static and noise, especially at large distances from the transmitter in colorado. Generated by special software / 48. 1 khz 16-bit stereo.

A close up recording of an overheating usb slot-loading cd/dvd drive that repeatedly tries to spin up, but fails and makes some clicking noises. Note on low frequency sounds: i recorded this with a zoom h1n recorder at about 2cm distance from the drive slot. I held the recorder in my hand and rested my hand on the surface the cd drive was resting on, so there is somewhat of a mechanical connection between the drive's vibrations and the recorder. I believe this led to the low frequency parts of the recording. About halfway through the recording, i lifted the drive up with my other hand and held it at a 30degree angle to the surface and recorder. As you can hear in the recording, this made it spin up a little longer before failing and spinning back down.

The story begins by a music that i found. A open door, heels, then silence, a chair, computer sounds with mouse, retake of music and close of the door. , who is the ending of music too. To produce that, i choose audacity; i take recorded moments of life. For the technique, i choose a fade in and fade out for the music and the recorded sounds fit well together. For the moments of silence, when the work begins, i only let the recorded sound talk without music. I choose to work with two mono audio tracks: on for the music and the other for the daily sounds.

Sounds like you are in a futuristic city terminal. This is of course meant to represent only one of many sounds - it is not complete without other futuristic sounds (if you want to make a futuristic city terminal atmosphere!). This sound reminds me of an old third-person shooter game which was released/published back in the days (year 2000!) -- messiah!. This sound can for example be used in sci-fi games, for example when the player is walking in a huge futuristic city terminal, or is interacting with an ai - you name it!. If you enjoyed the sound, please rate, comment, spread! it really helps!. Note: make sure to check out the other matrixxx-sounds! the sound quality is always better when you download the sound(s)! ⛄.

There i was late a night. I was turning my computer off after editing my site. I was silenced by night. But there was a storm a brewin' i opened my bedroom window and put my ear to the icy wind. I knew then this wasn't the usual mellow wind. I ran down the stair with my zoom h4n equipped, went through the garage into the black of night. I sent my gain levels to 60 and with only a foam wind shield i put it between to to boards of wood to act as a wind shield thus allowing my to capture the wind slicing through the trees. With only adjusting the gain levels slightly in post nothing else been done, allow you to add you own effect on it.

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.

Just me stretching, rubbing and 'twanging' a rubber exercise band. Apologies for the knocking in the first 20 seconds, my upstairs neighbour started moving some furniture. I made this recording for a very specific purpose but i suppose it could be used in an animation or computer game but also for something bondage or kink related?. 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 no processing to this recording other than to ‘normalize’ the levels. 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). Any donations are greatly appreciated!.

I recorded this in my living room with mics in an x-pattern on the couch very close together, using a tascam dr-70d and behringer dyynamic microphones with patch cables for optimal volume. I recorded this at maximum gain on the tascam as two stereo files, then conjoined them to a 6-channel audio file properly and mixed the front two channels to a monaural center channel for added effect. The final result is what can be downloaded here. Tghe music in the background is part of the star trek: generations expanded complete score, and is coming from my computer to the rear of the recording, which lasts just over a minute in length, and the music was just background noise for testing purposes only. No copyright infringement was intended. Credit for the music goes to the now late jerry goldsmith and also dennis mccarthy, who is still alive. I hope you like this audio demonstration, and find it useful when considering rigs like the holophone, or comparible 5. 1 surround sound microphones / rigs. I take no credit for this recording, as it was done for demonstration purposes only. Have fun!.

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.

Bonzi buddy saying the words milli-meters over and over and over again. . . For some reason this was in my computers files. No clue why and when i made it.

An actual new production instead of old stuff! made in june of 2020. A dark intro implies the humming engines of the spaceship you're in as you're traveling at speeds unimaginable. Slowly the ship starts to spring to life. As you open your eyes, slow but huge bands of light sweeps across your cryogenic sleeping pod, as if being scanned. The pod starts to move while you're still in it, going through chambers filled with machinery and bleeping computer stations, until it stops in front of a huge closed door. Suddenly, your pod opens up as well as the door. Your eyes are greeted with the majestic sight of a gigantic control room with windows as far as the eyes can see, galaxies fills your field of view, a beautiful synergetic view of the grandeur of space and the hundreds of lights of the control room, welcoming you to a new adventure. 2 simple chords form the basis of a textural composition supplied with sound effects. Plugins used: ni kontakt 5 with atom hub's the planet, doom by sampletraxx, space by rigid audio, ni absynth, and massive vst synths. Extra sound effects: shocking signal and ui designer by sampletraxx, heavily sampled and mangled. Effects: izotope mastering plugins, a bunch of fl studio stock reverb and eq, guitar rig 5, blackhole reverb, replika xt, raum reverb.

Droid kinda sounds from the lovely polygogo eurorack module. In this case it was processing cv input from an external lfo. Useful for laser sounds, droids, future computers, etc.

A short "fireball" sounding woosh. Originally created for game sfx. A combination of a gas stove lighting and burning, fan hums from several computers, and generated brown noise in audacity, all combined, equalized and shapped with a short fade in and longer fade out.

I made this after listening to the first track listen on this page:. Http://www. Redbullmusicacademy. Com/magazine/psychoacoustics-introduction-feature. Mr. Stockhausen has produces some amazingly real sounds back in the times when no computers were out there to do any dsp for him. Synthesized with zynaddsubfx within lmms.

Same program as in https://freesound. Org/s/457868/ butthe main clock (lfo_2) frequency is about 1hz. It's a minor scale?! as have split the octave in 5 equal parts. This strange scale sounds like a sort of minor scale.

A mosquito ringtone 11kHz. Nice to put on your phones or computers and piss people off with. They wont know where the hell its coming from. Very high pitch ringing sound, sounds just like that ringing you get in your ear sometimes. Nice for pranks.

What i hear in this sound is a crashing starship as you regain consciousness surrounded by chaos of the crew and emergency systems. At 00:52 there's a really cool explosion hit that fits the starship in danger vibe. Created from roughly 230 sounds in reaper by looping, batch actions and modulated filtering. All sounds came from a folder of freesound cc0 sounds i've been collecting. Here is the file list if you are curious:. 103117__geronimo83__elephant.

Rear channels of a 4ch-surround recording of the interior atmo of a small airbus passenger airliner (a lufthansa flight from london heathrow to berlin tegel). In the onset, you hear the steady drone of the jets, people talking, coughing, sneezing, newspapers rustling and notebook computers being typed on. Now and then, passengers and stewardesses pass by the aisle. Near the end, a signal bell sounds, and the drone of the jets takes on a perceivably higher tone, shortly after which the landing in berlin is announced, first in german, then in english. Recorded with a zoom h2, the mics (rear) set to 120° dispersion.

A recording of a high school class. Students were working on a sound effects project on computers, but generally allowed to talk as they worked. This is maybe 18 students, with the mic about 10 feet away from the nearest student, mic towards one side of the room, pointed towards the middle. We also have ac on, and an av cart that has a fan on, plus a wall clock, some of which you may not be able to hear over the students. Mic was the zoom h1 set to record a wav file, record level manual, low pass filter engaged, with the quality settings at the highest values. It was then put through audacity to amplify it to the highest allowable levels without distorting, and spit out as a wav.

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.
