285 Royalty-Free Audio Tracks for "Frequency Hum"

Lowercase clicks. Minimal. Subfrequencies.

Moving low frequencies sound fx.

This sound was the result of a scary accident. I was looking at the view in the webcam of an open doorway leading into a dark hallway in my house, when suddenly this haunting feedback faded in and looped repeatedly, until i pulled the volume down. It was unexpected, and quite unnerving. I had to laugh about it once i realized what had happened. But that first moment had me expecting some ghostly apparition to come in from the darkness. Anyhow, it's just an accidental feedback loop. I've had it in my archives for about 20 years now. I thought it might be useful to someone else. Enjoy!.

Rfi caught on an empty channel input on my sound devices 664.

Heavily compressed heartbeat taken from a sample after jumping jacks. . . Starting at approx. 180 bpm, then quickly slowing to 0.

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.

Bladerunner vibes, some sci-fi synth tones with a menacing threat.

The end result of plugging your tascam dr-05 recorder into the auxiliary output of my chevrolet aveo's car stereo: pure auditory madness!. Feel free to use this sound for whatever projects or pure enjoyment that you see fit. Have a blessed day!.

22-sharavana-sun, tibetan singing bowl the experimental mix-iii with ebc-174 & 396hz. Hello,this is the very real horst from town duisburg in germanyyou will hear an experimental mix of sounds created from energy bar chimes and tibetan singing bowl, mixed and modified with software audacity. This soundpiece includes different versions of stretched sounds from singing bowl with frequency of the sun as well as sounds from energy bar chimes frequencies solfeggio 174, aka foundation and 396 aka "liberation from fear" and binaural beats with frequency of the sun. Hope you'll enjoy listening and that you will find truepeace on your waythe very real horst.

Contact mic recording of a large folding clothes hanger/dryer. Tapped on the stems for hanging clothes to create some weird drone/percussion hits. Recorded with a lom geofon contact microphone into a sony pcm-a10 handheld recorder.

2:54 field recording interior of an empty lincolnshire office ambience on the third floor during high winds. Mics in the closed window. Recorded with a stereo pair of (different make) mics and edited to remove intrusions. Filter at 90hz.

This is a ready-to-go morphagene reel with markers for the fantastic make noise module. It contains a bunch of different recordings i made with an iphone and the mixpre iii. Just download, rename to suit a morphagene, and. . . Soouuunnd!.

Heavy kick with a low frequency slide. Classic dance music phrasing fx for chorus to build/break transitions. [format: wav][license: cc 0].

The orange side of plaits randomised from rnd step driven by wogglebug and instruo neoni, into harmonaig, cv to plaits. Aux channel passed through rings, one output through tau phaser the other through mimeophon and finally though qmmg moved by maths and sent through erbe-verb. Phew! enjoy! oh yes, markers are in place for morphagene.

Radio switching frequencies with lots of static and radio noise. Recorded on edirol r-09, 48k, 24 bps. Free to use anyway you like!.

Synth loop from my track charged from years back. Custom synth, and pretty harsh and heavy to boot. License: cc 0.

Taken from a window, this is a soundscape in vilnius old town, lithuania. You can hear a concert happening far away, cars, and general city hum / noise.

Ringmodulated inversion of my speech from the file https://freesound. Org/people/kb7clx/sounds/648443/ invertedspeechcq. Wav. I took the raw recording and used goldwave's mechanize effect to translate my voice to a center frequency of 14khz. I then demodulated it first at 10. 6 and then 10. 2khz meaning that what comes out is essentially the opposite sideband, offset by 3. 4 and 3. 8khz respectively. 3khz just didn't sound as good. The first i filtered with a low pass of 2. 9khz, the second was filtered to below 3. 4khz to emulate a communications receiver passband. I am speaking upside down as described in this video. Https://www. Youtube. Com/watch?v=q_ykxzcbh-g beginning at 00:03:16. Being blind i can't see their diagram, but i've got my own by ear intuitive method, keeping in mind that oo and ee are farthest from each other, all other vowells get closer the closer they are to the middle of the human voice frequency range. I say: huhlay sue quee, sue quee, sue quee do ux. Cahlloong sue quee sue quee sue quee do ux. The ay in huhllay is like when a spanish speaker says béisbol (baseball). The a in cahlloong is like the a in cat if you're opening wide for the doctor. The oo is like the oo in book. Listen to the other file and you'll hear: hello cq cq cq dx. Calling cq cq cq dx.

Low frequency atmosphere made from microphone hum.

Removed the hum from cognito-perceptu's pill-bottle-4 sample. Original sample had truck in background in addition to some low frequency hum. Used the remove hum feature on izotope rx2 and, presto-chango, no distracting background noise. Now there is still a high frequency hum which i did not touch. I think this could be mitigated with a low pass filter in eq if you choose.

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.

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.

An irregular rattling noise from a 70 years old electromechanical electricity meter along with a constant mid-frequency hum.

This delta binaural beats is exactly 2hz apart and loop perfectly at 30s. Set at the low base frequency of 40hz and 42hz, it's a relaxing hum.

Waves on a winter beach. It may be good for those who love nature ambiances. I used audio-technica bp4025 half plunged into my bag, which sometimes masks right channel. A distant ship makes slight low frequency hum. Korg mr-2.

Damaged smartphone screen protector being broken and crushed in bare hands (should've used gloves. . . ). Recorded with behringer b-1 microphone into focusrite scarlett 2i2 3rd gen. Into audacity on arch linux at 192 khz/24 bit. The recording was not processed or edited in any way to retain maximum flexibility to sound artists who will use this as an element. This can be useful as a sound effect for freezing or burning or deep-frying or even rain (when slowed down). Thanks to extremely wide frequency range the recording can be cleanly slowed down up to 25% speed. There's clean frequency content up to 80 khz in the recording. In a few places the mic gain was too much and a pop is clipped, but could still be useful for sound of braking or snapping something (bone?). No denoising was applied - perform your own if needed, though the sounds are mostly free of background hum (a bit of pc noise can be heard in the first minute before i turned down the gain).

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!.
