[pink_noise_20_sec. Wav]. Pink noise! disturbing to some, relaxing to some. This sound can for example be used in horror games; imagine a zombie apocalypse, when the player for example enters a silent, abandoned house, and hears this from a tv, or why not for example use this sound as a starting point when creating a wind-sound? - 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.

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.

This is a sound recorded with a handcrafted electromagnetic microphone (that is why is in mono format). The machine recorded is used for signal processing tasks at cbc (upf) for their experiments on brain cognition. As researchers of the center for brain and cognition, we work to advance our understanding of how experience influences the emergence of structure and function through computational and experimental investigation. We are also interested in understanding how mechanisms regulating brain development interact with the effects of experience to produce the structural and functional characteristics of the brain. These lines of research clarify how specific biological mechanisms routinely support the emergence of cognitive functions, leading to insights into why experience is so important for normal brain development.

This is the companion audio to the article "modify your monitor audio" appearing on w1zy's substack account. In it, we hear what happens when you mix through a soundboard the audio from a ham radio transmitter's "monitor" output and a second receiver dialed onto the transmitter's output frequency. When the two are mixed, we hear a heterodyning between the external receiver and the transmitter monitor audio sources. By adjusting the receiver's frequency to that of the transmitted signal, we can zero-beat the two audio sources together producing a "flange" effect derived from analog devices. Non-ham audio enthusiasts might find this clip interesting since it is producing this artifact not through some plug-in, but through use of "legacy" analog equipment.

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.

This is my first recording using my binaural mic. I took a walk to meet my wife for lunch and decided to record it. It was windy outside, and even with the standard foam wind protection, you can still hear some wind rumble. It might be fixed using some low cut filtering but i wanted to post it as is. This take started inside my recording studio and ended in a fairly large avenue with lots of traffic (cars and motorcycles). There is a pause on the recording by 01:59, when i had to change the mic cable position. Signal chain: roland cs-10em (with foam windscreen) > sony pcm-m10 (rec level: manual, at about 3,5; mic sensitivity: low; limiter: off; low cut filter: disabled).

This, my dear friend, is ils - infinitely loud silence. Play some other sounds and then play this, and you'll know why i call it this way. It's created by a bug present in lmms, a free program for electronic music production. Actually this sample can't reproduce the ils phenomenon, that creates a dc offset so big, that it outnumbers any other signal getting out of the same audio interface and the result is silence. It's a silence that is masking other sounds. Mind-boggling. Nasty bug. All this sound can do is cause some distortion, probably because 24-bit sound can be only as loud as 0db. 32-bit floating point should be able to get louder, but still i don't think any sample file would be able to reproduce this product of error.

This is the audible annunciation found at all intersections with traffic lights in paris, france. It announces the condition of the traffic lights for pedestrians who are blind or with impaired vision. The annunciation is turned on by pressing a button on the traffic light pole. When the crosswalk sign is red (do not cross), the recorded annunciation is always "rouge piéton" ("red light, pedestrian"), followed by the name of the street that the crosswalk crosses (in this case "rue d'antin," the quiet side street where i recorded this). This repeats over and over until the crosswalk changes to green, at which point there is a two-second trill tone followed by a repeating bell tone. The bell tone is one bell, followed by two bells, repeated four times, followed by a very brief pause, and then the sequence is repeated again. This continues until the crosswalk changes back to red, at which point the "rouge piéton" message resumes. The annunciation continues for at least one cycle of the traffic lights and then stops, unless the button is pressed again. The audio quality of the annunciation is very poor even in real life (it sounds like a wax cylinder recording or something), and can be difficult to understand. This recording accurately captures the poor quality of the annunciation. The volume of the annunciation is also adjusted dynamically based on ambient noise, so there is a slight change in volume on this recording as the system apparently reacts to noise from traffic or something. There is a weak background noise that sounds like some sort of machine, but it wasn't coming from the traffic light and i don't know the source. The recording starts with the crosswalk red, then at about 18. 3 seconds it changes to green, then it changes back to red at about 53 seconds. A car passes at around 48 seconds. Recorded with a zoom h4n, stereo 96 khz / 24 bits, built-in mics, from about ten inches below the tiny speaker in the crosswalk sign housing.

The guest room i am staying in has a tile bathroom. Each time i take a shower, i hear this magnificent hum of the water heater clicking on and then turning off once the shower water is stopped. I was fortunate enough to hear it click on while i wasn't in the shower and captured about 30 seconds of it before it died. Infinite variation, impossible to replicate. At the end, as the water heater shuts down, it clicks down into the lowest ranges of the frequency spectrum; i didn't hear it until i listened to the recording but the couple of seconds of that are just as magical. Wish i would have left the recorder running!. Captured with a zoom h3-vr to ambix format at 96k24bit and bounced to stereo. Processing: 24db gain to all 4 clips, izotope spectral denoise to get rid of the air in the room and izotope ozone to enhance the bass signal a touch. Enjoy!.

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.

Non-functional tube radio warming up, making a loud 60hz hum with lots of harmonics. As a bonus it clicks off at the end. Zenith consoltone. Only because the faq says so: electro voice n/d 257a through impedance transformer into crappy gigabyte motherboard realtek high definition audio. 16bits, processed at 32bits. Audacity sound editor and/or driver wouldn't record mic level so it was very noisy after amplification. Filtered with a (mathematically equivalent) fft constructed whopping 64k length zero phase filter (blackman window) with 5 wavelength width bandpass at each harmonic from 60hz to 5,520hz. For some reason a fraction of some of the harmonics didn't get through so did another pass on the residual noise and mixed that in. Near the beginning there was a sort of brief duplicate signal that descended in pitch so it didn't make it through the filter. I added that bit in. Attenuated frequencies above 3. 6khz because they are pretty much noise, but removing them didn't sound right. Cleaned up the beginning a bit in various ways, cut it down to 15 sec and carefully appended the unfiltered "click" onto the end, which i denoised 12db with audacity's noise reduction.

Created by divkid for use in the make noise soundhack morphagene. There are dry-only, fx-only, and mix versions of this reel in the pack. See it in action at https://youtu. Be/rk4ufmfcouc. Patch walkthrough. The patch starts with the qu-bit chance providing discrete random values (sample and hold) going into an instruo harmonaig. This takes the stepped random voltages and quantizing them to a given scale. I put in the notes c d eb f g ab bb which is a c natural minor scale, the relative minor of eb major (for anyone that's curious). However like most of my modular work i didn't actually tune the oscillators to anything specific. So treat the scale as a pattern of intervals not a set of specific notes. The quantized notes then form 4 voice chords giving us a root, third, fifth and seventh cv output that will be diatonic following the scale pattern, meaning the third will be major or minor, the seventh major, minor or dominant and the fifth natural or diminshed to suit the scale. With the 4 quantized outputs on the harmonaig these all go into the four oscillators on the synthesis technology e370 quad morphing vco. Each of the e370 oscillators are in the basic morph xy mode using the built in rom b set of wavetables. Wavetables are modulating by various mixes of the befaco rampage, mutable instruments tides, wmd multimode envelopes and music thing modular turing machine. The modulation sources are mixed and split with multiples and mixers. These modulating wavetables then go into a bubblesound vca4p where i'm using 4 mk1 intellijel dixie oscillators all un-synced and free running with sine wave lfos. Each lfo freely fades the voice in and out of the vca4p. As this is unsynced there's no regard to pitch changes linked to changes in amplitude and the swells. I find splitting the gate/rhythm from pitch regarding sequencing to be a freeing and interesting way to work that's not available on traditional instruments. This is just a simple application of that idea with the lfos fading freely unrelated to the other modulation or sequencing of pitch. The sound then goes from the vca4p mix out into a befaco mixer and praxis snake charmer which the output section of the larger case and i'm sending a 'pre' auxiliary out into my fx case. The dry sound first goes into the erica synths fusion delay / flanger vintage ensemble which is giving me short modulated delays giving vibrato like sounds and pushing the input level and overdrive gives us some warmth and grit that thickens up the sound and also fills in the gaps left by the free running lfos pulling quieter sounds and compressing in the on board tube. This then outputs to the feedback 1 bit multitap delay module which has it's delay chip pushed to longer times for some added crackle and noise. I'm using the two delay taps for a shorter and longer delay with little feedback to mix the dry sound for a generally noisier and smeared version of the input. This then goes into the xaoc devices kamieniec with it's on board lfo as slow as possibly for a mildly resonant phase shifting. This goes into mutable instruments clouds set to sew random grains slowly and randomly which are pitch shifted up 2 octaves to fill out some high end flourishes against the closed chord voicings at the core of the patch. Finally this goes into a long lush reverb from the halls of valhalla card in the tiptop audio z-dsp. The stereo fx chain and the mono dry signal are mixed in the befaco hexmix and recorded as a mixed stereo file. I'd consider this to be the main 'reel'. However i split the dry signal and the fx only wet stereo signal and recorded those at the same time so you can choose which reel to use and experiment with dry/wet or blended sounds from this patch.

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.

I recorded this today (1/12/23) from atlanta, where we had a bunch of heavy rain and tornado warnings this afternoon. The radio station i recorded this from is am 750. The first part of the recording isn't very interesting, but the part where she started talking about how you can't see any tornados coming was really interesting to me. I think this would make for some really good ambience in like an environmental horror track. I decided to include the whole recording anyways in case anyone wanted it. Here's the backstory to this thingey if anyone really wants it:we were on tornado watch as i was speeding trying to get home from work, when the sirens started to go off. I had to pull into a disheveled looking parking garage, as that was the closest place i could get to. The garage only had one level, so i had no way of getting to lower ground. I sat there in my car, terrified that i might be stuck there, in a shitty parking deck, in the middle of a giant ass storm, with very little cell signal, for hours on end. I decided to turn on my radio and record it from my phone. Fortunately, i was only in there for 30 minutes, and i managed to get home after the rain cleared up a bit.

While working on another audiobook, i decided to make this sound. It's 38 voices, each saying different things, panned around and mixed together, creating a "wall of sound" that speaks like 38 radio channels at once. Recorded with a zoom h2 via usb into ardour2. Mixed and exported to flac with ardour2. Ps: it's all polish (with some possible german shout-outs), but the amount of noise makes it almost completely incomprehensible. Only a few words that are being yelled in a different voice can be understood. No sound repeats here, no recycling - every voice and every second of this recording is unique. Yes, it required quite a lot of work to record so much talking in quality! it's almost an entire audiobook squeezed into 5 minutes. Strangely (or not) listening to this makes my mind rest, because the noise blocks all other sounds from the environment - making my mind free of stimulation, allowing for sleep-like rest state. The signal is so much modulated that it appears to be not modulated at all - like static you get from a fm radio of you tune it wrong. The brain receives less data when you listen to this, than when you sit in a room hearing even faint (but distinct) noises from outside, other rooms, other people or yourself. This is sound masking in action. A very interesting psychoacoustic property of human hearing. Also: this is an interesting material to study of my voice's spectral energy distribution while speaking (as opposed to singing). As you can see using the spectrogram view, most energy is present in the band below 600 hz.

Native instruments battery3 was triggered by explosion of fireworks. I recorded fireworks and change it into midi notes with logic 7. Smaller signals are played by edirol sd-80 triggered by ambient noises around me.

Broadcasting from jabba di hut's planet. Radio techies work hard to clean from hostile disturbing signals. Finally they could sort out jabba's voice and instruments in the background.
