36 Royalty-Free Audio Tracks for "Frequency Hum"

Here is a sound that i produced in audacity by generating a tone and making the frequency very low. It sounds rather like a humming of a machine or electrical appliance! good for looping and such. Enjoy !.

Low frequency atmosphere made from microphone hum.

A wet finger rubbing on the outside edge of a crystal wine glass.

A low frequency hum that will work on pc speakers (at least it does on my pc). . - i made this sound because i needed a deep hum for a composition, but as it turned out my pc speakers cut off low frequencies. A quick googling taught me that this is common for many pc's, but also that there might be ways around it in terms of designing waves that the speakers can produce. And so, after playing around with audacity abit, i came up with this low frequency hum that works well for my purpose at least. - i hope it might help others with similar issues.

This is a recording of very low frequency hum of a steel mill. The sample has been low pass filtered. The main frequency is about at 25hz. The sound was recorded some distance away of the steel mill area, where it mixed with other sounds as a constant hum, which could be felt in body too at certain spots.

Noise with a lot of low frequencies.

Vhs hum made in audacity when playing around with frequencies.

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.

Dead air humming static at 103. 3 on the fm radio dial.

Noise from a switched-off radio frequency receiver connected to an active recorder.

Dead air static with a "singing" hum at 103. 3 on the fm radio dial, with the volume boosted and slight effect added.

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

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.

Humming and whistling through my teeth, granulated and highpassed.

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.

Static on the radio as a result of tuning a few channels down on an existing radio station. A voice is heard but their words are undecipherable.

A close recording of a ringing ride cymbal. Useful as a drone or feedback-like ringing. All my sounds are fully free to use, but please consider leaving a comment to let me know how you'll be using them. Just curious! :).

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.

I recorded the fan on quite loud and i opened and closed the cd drive on my hp eletebook 8460p, different laptop models have a different frequency from the fan and different cd drives make a different sound when checking it. Recorded from the internal microphone.

Noises from an old gdr tube radio (1966, oberon) when tuning through mw, lw and ukw bands. I tried to separate the different noises and let them be heard for a few seconds so you can edit the noises you need. First there's lw, then mw then a few noises from buttons on the radio then ukw at the end with fragments of some german radio stations in 2021.

This sample consists of noise recorded via a hondo strat electric guitar resp. The guitar's neck pickup. Throughout the sample there is a low hum. In the beginning, a mobile phone was moved in front of the pickup. The noise might have been created by the clock of the phone's cpu or the backlight of the phone. After that, one crt display is switched on resulting in a buzz. Later on, a second crt display is switched on, again resulting in a buzz followed by additional noise in higher frequencies. Then, a neon light is switched on, creating even more noise. Towards the end, again the mobile phone. . . The guitar was connected to a scott&noble ht25r amplifier which was recorded with a t. Bone sc450 condenser and a behringer ddx3216 digital console directly into ardour.

Electric machine, engine, large air conditioning unit, hum, noise, field recording. Recording device: roland r-26 portable digital recorder. Microphone: built-in directional xy stereo microphone. Sample rate: 44100 hz. Rec format: wav 16-bit. Edited in: adobe audition (adjusted gain slightly, for a good signal level). Date and location: october 2015, a rather large air conditioning unit in a public parking garage, in sweden. Other: this is an original recording, by myself, which i make available to all via freesound. Org under a creative common 0 (zero) license, i. E. I am putting it into the public domain.

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.

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).

Laboratory refrigerator, with beeping, plus the sound of a door being closed in the background, field recording. Recording device: roland r-26 portable digital recorder.

I have built a nonlinearcircuits sloth lfo, the regular version. Sloth is a chaotic lfo. The output is based on the lorenz system. It is a system of ordinary differential equations. It is notable for having chaotic solutions for certain parameter values and initial conditions. In particular, the lorenz attractor is a set of chaotic solutions of the lorenz system which, when plotted, resemble a butterfly or figure eight (very much from wikipedia). The sloth has two outputs x and y. Think of them as coordinate pairs. The output will probably never repeat itself but there is a pattern. I have built the regular sloth it usually takes approx 15 seconds to make a rough figure 8, one cycle in the “butterly”. Now i’m testing the module in different ways. In this sound i have connected white noise to a filter. The filter frequency is controlled by sloth (x output). In this patch i have set the initial frequency low. That’s why there is a low humming wind noise between the “tops”. The output sound from filter goes to reverb. The sound is more a study of sloth behavior than an attempt to create a great wind sound.

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!.
