487 Royalty-Free Audio Tracks for "Unit"

Rain & distant thunder around 8pm in warren, michigan (suburb of detroit). Recorded on a zoom h1n. Some faint traffic sounds & a bit of white noise coming from an air-conditioner unit. Zoom h1n was placed in my porch light compartment about 2 feet below our rain gutter. Most of the original hour long recording was ruined due to wind gust, but i edited it down to the only continuous 11 minutes without the gust of wind.

This was recorded in my kitchen next to a railway, late at night when there was maintenance going on on the line. A heavy unit called a tamper went past, tamping down the ballast (stones) that go under the tracks. Lots of sub-bass as the whole building gets vibrated and at -04:29 a balanced teapot lid puts itself onto the teapot. Zoom h4n, 24/48 wav exported to flac in audacity.

I asked for a fabric shredder because i couldn't find one, and i knew my dearest would knock himself out trying to. He didn't either but he did have one made, probably at considerable expense. It's a cute little portable unit, i think made of a modified paper(?) shredder, powered by a geared motor from a battery-operated power tool. It's probably a dangerous little work of art. So we're getting dressed in the bedroom after opening gifts on christmas morning, and i decided to try out my new toy. Good conversation, mechanical whir.

Gem pathescope 9. 5mm projector, unit #1191, made in england. Recorded on a marantz pmd661 with a rode nt4 stereo mike. The gem is a variable speed projector, controlled by a rheostat. Speed for this recording begins at about 12 fps. Microphone was facing the non-roller side of the projector, 30 cm away. Audio begins with power being turned on, ends with power being turned off. The end of the film leaves the gate at 4. 37 and becomes free of the last roller at 4. 40, when the motor speeds up. The speed and audio-level variations during recording occurred naturally.

Checked-in to a hotel in raleigh, north carolina with my wife to catch a flight early the next morning out of rdu. Suddenly, a storm rolled in to the area and, since we were going to bed anyway, i placed my zoomh4npro (120 degree setting) on the air conditioning unit below the window. I slid the window open just enough for clear audio without getting the microphones wet. Enjoy!. Christopher.

This was recorded as part of a tracking shot for a project i did a few years ago. It starts off from the exterior of a fancy london pub around the primrose hill area, walking in to a fairly packed establishment. It tracks movement into different parts of the pub. There's fairly prominent music for the first half but it eases off to barely audible later on in the audio. A few minutes in, you'll hear the bartender announce the price (6. 95) a couple of times. Recorded on zoom h6 with x/y capsule.

Sound created from using the rings of saturn as a spectral source to a series of filters. When a 1 pixel high image of the rings is extracted it looks like a spectrogram (original: https://en. Wikipedia. Org/wiki/file:saturn%27s_rings_dark_side_mosaic. Jpg). The ring spectrogram was divided into three color planes, and the color intensity values were transformed into resonant filter cutoff frequencies. In essence one filter unit (per color plane) has 256 sounds playing simultaneously. The individual filters are placed along the x-axis so, that the stereo image consists of 256 steps from left to right. In this sound of the series the spectrum was compressed to a range of 20 - 1000 hz. A small variation in certain divider factor per color plane is introduced for a slight chorus like effect.

It's recording of a passenger train's on duty. You can hear the train's motors, the wheels rumbling against the rails, the wagon connectors hitting each other, when the train stops also people chatting. Near the end of the recording the room acoustics change, because a woman entered the area between wagons where i was standing with my recorded pointed down. I was standing in a narrow passage, where two wagons were joined, between two closed slide-doors. She have opened those so the overall sound has radically changed and i decided to end the recording. Through the entire recording the unit is moving forward, decelerating, stopping, staring and accelerating again repeatedly as it travels stopping at several stations. The recording was done with a hand-held zoom h2. Rear mics used pointed to the ground. I was in the loudest area in the whole train. I was using "low" gain (h2 has three mic gain levels to choose from: l/m/h). Viewed and converted to flac using audacity, the file hasn't been altered in any other way. Originally recorded as a 96khz/24-bit stereo wav file.

This sound is a 1-sample long impulse at 48 khz. It covers the whole frequency range with equal power. This is a perfect sample for exciting your guitar amp or reverb unit to capture it's impulse response (ir). You can also play it through a speaker in a reverbant room to capture it's reverb characteristics. Remember that the ir sample will be no flatter than your speaker's performance multiplied by your microphone's performance (frequency response characteristics). The sample has exaclty 1 second of silence, then the impulse, then another second of silence to ensure the impulse will be played clean and untruncated on any sound system or device. My test with ir lv2 convolution plugin have proven, that this sample has absolutely flat frequency response - convolved signal was identical to the source signal. After normalization and sample-alignment of the sound clips i have inverted the polarisatin of one of them and summed them - result was absolute silence, even no hiss was present as a result. This shows the accuracy of the convolution process and proves this sound to be perfect for sampling ir. The impusle was generated with c* dirac ladspa plugin. Created using audacity.

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.

Studio technologies - stereo simulator (generation ii). Https://studio-tech. Com/products/generation-ii-stereo-simulator/. The generation ii stereo simulator from studio technologies creates a convincing stereo imagefrom a mono audio source. The fully mono-compatible signal simulates space withoutreverberation by using random, non-recursive filter techniques. The mode switch (found on the hardware unit) controls the overall sound of the generation ii. In the music position, the full audio bandwidth of the input signal is simulated. This mode isappropriate for audio material with little or no voice-only content. In the music & voice position, the input signal is sent through a band-reject filter prior togetting sent to the simulator circuits. This creates stereo simulation over the low and highfrequency range, while limiting simulation in the voice band. This mode is appropriate for audiomaterial that contains voice-only content, such as a film track or television show. The stereo intensity control determines the amount of stereo simulation that is produced. Inthe fully counterclockwise position (ir files “0” – included for process comparison), no simulatedstereo is produced. The mono input signal is sent equally to the left and right outputs. As thecontrol is turned clockwise (ir files “1 – 6”), the amount of stereo simulation increases.

I made this sound in september 2003 - i used a fairlight mfx 3 - a direct descendant of the first sampler ever made - and the best ever to this day editing software for ground breaking features and functions. Clip based eq and level which you could cross fade between made the use of automation almost redundant in precise to picture editing. It also had a unique alternative jog function. You could loop 1 frame or so as you chose of sound at the orginal pitch which made it easy to find transient points. I then 'grind' the play head over a solo'd sound and play this into a reverb unit. I have many of these accidental experiments and one day i shall make the fairlight pack!. Until then enjoy this alien - from mars with love :). Ps - you can do this experiment today! i found that i can use sound flower as an out put in audio finder. If you open a sample in the sample editor - you can recreate the fairlight jpg by grabbing the playback head in play. You may then route sound flower thru an input channel and get some unusual effects that are difficult to achieve. . If you can improve on this method let me know!.

A combination of several tube spring reverb units with a dark vintage character.

Four military performance jets streak by. The polluting background hum as the planes subside is from keening air conditioning units.

Electric guitar ran through some vst delay and reverb units. Sounds like a pad.

Short recording of a suburb in the summer, with some light rain starting. A/c units audible. Recorded with zoom h4n on-board stereo mics.

Handy h2 zoom 4ch recording of supermarket checkout line. Hum is from refrigerator units nearby. Try using eq to rolloff the low end frequency hum of the refrigerator.

An old lady feeds the gulls with bread. There's a large bank of air-conditioning units running close by. Olympus ls-5, internal capsules. 22-12-07_092452_lady_feeds_gulls_ls5. Wav.

This is part of a commercial summer firework display in the uk. There are bombette candles, crackle candles, tourbillion units and shells of various calibre, some of which contain crackling material. Analogue recording.

Part of a firework display. Can hear roman candles with screamer units, and the launch and burst of shells. You may wish to turn up the bass and wear headphones! now geotagged at last - thanks for all the comments!.

Hardstyle kick made in fl studio using few 3xosc layers and a bunch of eq's, filters and distortion units. Also used some reverb to give some character to it (i always put my kicks in mono while producing a song).

This is a sum of two units, a digital reverb ams rmx16 and spring reverb fisher k10 with gate, this was an experiment i wanted to do and by the way, it worked well.

A sample made by myself (Paul Nasca) using ZynAddSubFX and Praat that will be used to show the RingModulation effect. This is the a sample ring-modulated by a sound of 2500 Hz.

A mockingbird going through its repertoire on a slow downtown morning. The background hum is probably large air conditioning units or perhaps a generator in the distance at a construction site. A car passes midway through the recording, approaching from behind so the stereo effect is almost nonexistent.

An enjoyable trip back to my childhood. . . Way before cell phones and the internet. Summers were enjoyed walking on the gravel alleys looking at the beautiful, mature trees in my own little corner of the neighborhood. Does this return you to your childhood?. A nice capture of those beautiful chimney swifts twittering above -- a true signature of summer -- occurs at 38 seconds in, then again at 2:24. The typical hum of central air conditioning units is ever present throughout. From 2:11 to 2:27 i stop and you can hear the hum of these units getting louder. At 2:44 a dog barks in the distance. Then, at 4:16 i leave the gravel alley and start walking on the grass, the, at 5:06, up the big, concrete front steps. Recorded at 7:45pm on the evening of wednesday june 12th 2019. Equipment: mixpre-6 recorder, with sennheiser mkh 416. Enjoy.

A wonderful typical mid-summer soundscape of cicadas, and some katydids recorded on the edge of a small town in illinois. Towards the end of the recording you will hear a very cool doppler-effect as the truck passes from right to left. Recorded about 8:00 at night with my zoom h4-n recorder using it's internal microphones. I had the volume level set fairly high -- 80 -- so you will probably also hear the constant hum of the various central air conditioning units. .

This is a short, but detailed audio recording from my police scanner. It is the "ending" of a dea surveillance being held in my local community. You will hear the dea agents (ground units) following the target suspect as he leaves home, then eventually at the end, you will hear the local pd meeting up with them to stop and capture the suspect. Because of the short-range distant of the dea's radio transmissions, some audio will be "scratchy", yet it is audible. Enjoy!.

Class 52 “western” diesel-hydraulic locomotive, d1015 “western champion”, powered by two maybach md655 units (each developing 1,350 bhp). Recorded at cardiff central railway station, south wales, uk, 27 october 2007. Background station noises are also recorded, “western champion” is heard with the maybachs idling whilst the locomotive is at rest. The change in engine pitch is when “western champion” accelerates away from the station pulling a train of eight coaches. Recorded, hand held, using built-in microphone to a pentax opti 750z digital camera.

What a storm last night! it was already dark outside as i saw lighting in the distance. It was kind of a scary situation but for sound i thought it will be awesome! i opened the balcony door and rolled down the 30 years old window blind ( i have a sound of this blind here on the channel) behind the window blind i started recording how the rain hammered against the blind! you can also listen to the wind between the units on this blind! i also recorded with the go pro the outside so that you can see the thunder, the rain and the lightning!.

Example 12 from Stockhausen's article "… wie die Zeit vergeht …", illustrating with a version of the series from Gruppen fur drei Orchester that, "if you start from the intervals of a proportion series, then with every step forward the register of each duration is also already chosen" (Stockhausen 1963b, 117). There are "a number of basic durations, indicated in metronome marks and corresponding with the pitch proportions within the series, reaching far as the octave positions (basic duration units)" (Leeuw 2005, 174), or "a duration scale which changes its 'time register' … corresponds to a twelve-tone scale that extends over more than one octave" (Misch 1998, 157–58).

A recording made around noon on the edge of a woods located right in the middle of a major midwestern university. Throughout this entire recording, you'll hear the everpresent hum of heating and air conditioner units running. You will also hear faint conversations and laughter of students as they walk to class, faint sounds from a nearby construction site, distant rumble of traffic, the distant droning of an airplane lazily floating through the april sky. From time to time you will also hear the well known "beep. . . Beep. . . . . Beep. . . . " of a piece of heavy equipment backing up. However, despite all of the dominating background of man and his machines, nature comes through. Sincei was sitting on the edge of a fairly large woods which sits in the center of all of the concrete and glass and steel, the sweet singing of birds lasts throughout much of this recording. Equipment used: zoom h4n recorder using the internal stereo microphones set on 180 degrees for the greatest sound capture.

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.
