285 Royalty-Free Audio Tracks for "Frequency Hum"

Sounds like it was a morse code sent by a human.

Radio motorola.

A sounds made with a microwave. High pitched sound looped 15 times. Enjoy!.

An artistic experiment searching for sound emissions and the limit of human hearing. Composed of infrasonic material that have a lot of harmonic distortion. Humans will be able to identify tones as low as 12hz. From 1000 hz the auditory system decreases. Natural and human produced infrasonic sounds is anywhere, all the time. The artistic idea was to use background noises, signal fidelity, harmonic distortion, low-frequency in order to foster a soundscape of infrasound that travels through space. Made for project that was never released. Think somebody might enjoy or use it.

I've scanned the radio frequencies with an old radio and recorded with my tascam dr-05 via the headphone jack. You can hear some weird looping patterns and sound fragments from random radio stations.

Turning on and off an old tube tv.

Appended series of different recordings of neighbours slamming their doors. Noise reduction and reverb applied.

This is a recording of myself sleeping, beginning ~ 1:00 am local time (~ 3hrs after going to bed) on january 10th, 2020 (which i later discovered was a full moon). I was in the midst of experimenting with recording myself all night long out of curiosity, using a laptop placed near the head of my bed. This particular recording was the only anomalous one (the rest consisting mostly of just breathing or snoring with occasional sleep-talking). This ~2 hour recording has several interesting properties, which make it hard for me to believe that these sounds were actually going on while i was sleeping. On the other hand, i don't have a memory of editing this file if i did. Either way, i find it unsettling. I found the file in oct 2021 while organizing my samples. As far as i can remember, this is the original raw recording. On further inspection, i discovered that it has some additional peculiar properties that make it even harder to believe i could have made it without remembering doing so. The audio spans almost exactly 118min (7080s). There’s a frequency sweep with a cycle-length of 6480ms that repeats throughout the entire recording. Dividing the 118min by 6. 48min (60 cycles) results in 18 parts containing exactly 60 cycles and a remainder of 12 cycles. If you think you know the source of the strange sounds or if you've ever heard anything similar, please let me know in the comments or email me at storyofthelie@protonmail. Com.

The wonderful sounds of a 1981 ibm pc model 5150 being turned on, the 5. 25" disk drive checking if a diskette is inserted, the pc emitting its idle hum, and finally being turned back off.

This is the stereo file of the 4-ch thunder-file--> https://freesound. Org/s/367222/. The thunder is slow downed to 0,7speed and has now very deep frequencies, which can shake your house, if you have the right equipment to play the file. ;-)the 4 channels are recorded in irt-cross technique so it is a 360° record. Ch1(left) = fl+rlch2(right) = fr+rr. _________________________________________________________________used recording gear:zoom f84 x rode nt1 (without "a" = the black ones).

Frozen reverb with an ear-piercing whine.

I made this as a strange wake-up alarm. I was wondering at what point i will wake-up? what frequency will break my dream and bring me back on earth?. Created using audacity.

A high-frequency electronic discord tone (sweeping around high frequencies) suitable for ringtones and annoying dogs. Also suitable as a sound effect for 'sweeping the dial' on shortwave radio.

Scrolling through various shortwave frequencies, caught couple tones among the noise. Sounded like sad horns. Radio used was a grundig yacht boy 207 with a broken antenna, recorded on a tascam dr-05x.

An artistic experiment searching for sound emissions and the limit of human hearing. Composed of infrasonic material that have a low acoustic impedance. Humans will be able to identify tones as low as 12hz. Natural and human produced infrasonic sounds is anywhere, all the time. The artistic idea was to use background noises, signal fidelity, harmonic distortion, low-frequency in order to foster a soundscape of infrasound that travels through space.

Something for the acid generation. Loops perfectly, twisted in realtime, 113bpm, do what you want with it, enjoy ^_^.

Synthesized soundit's a regular sine with a fast, chaotic pitch modulation9 notes, first note on each octavesurge xt synthesizer.

Shopping cart wheels, freezer hum, cashier scanning beeps, announcement on pa.

I played arbitrary co-soundings on the mystic scale (it becomes mystic arabian if you mimic arabian music; otherwise is sounds european). I applied 300 hz steep low pass (eq) on an inverse sawtooth soundwave generator. I applied many delay effects in tandem. Created on fruity loops and re-equed on wavelab. Mystic(has three submodes, scale-shifts [same intervals, overall shifted]). • do, re#, mi, sol, sol#, si• do, do#, mi, fa, sol#, la• do#, re, fa, fa# la, la#. (semitonally/fret steps: 0, +1, +3, +1, +3, +1, +3). (si = ti, do = c). It is chordable.

Eerie transmission from outerspace.

Synth phrase in d minor. Looped and used many times in live performance as a pad, kind of a drony texture with delays.

Just messing around with radio frequency and stuff on.

A drumsequence for breakdowns or interludes with a lot of effects in it. If u like this, also have a look at my tunes: http://soundcloud. Com/beverlyhillsboy cheers!.

Scrolling through various shortwave frequencies, caught a tone that slowly turned into a beep with rising tempo. Radio used was a grundig yacht boy 207 with a broken antenna, recorded on a tascam dr-05x.

Fizzle and hiss, together as one.

This is a break i made to layer over my breaks at 102bpm. It was created in free tracker jeskola buzz using vst instrument, alchemy, multiloop2-move knob 1. This is not a looped sample from the instrument, i created it using the tracker, then applied an ohm boys delay effect. Sounds great over the breaks at 102. Enjoy :).

Exploring the medium wave frequencies. Everything here sounds creepy. Radio used was a grundig yacht boy 207 with a broken antenna, recorded on a tascam dr-05x.

A bunch of birds (sparrows, blackbirds, swallows and some more) singing in glorious stereo. No low frequencies, just birds.

Tiny clip of frozen reverb. Probably good for granular synthesis.

I initially created this snare using lmms ( linux multimedia studio ) and a single instance of the zynaddsubfx plugin. There were many effects and experiments done before exporting as an audio stem. Next i opened this stem ( single snare hit ) in bitwig studio and made a few copies of it and timestretched and chopped and then joined together in a group track the parts i liked to make the whole sound. Final effects included saturation, equalization , sidechain-limiting and compression.

Here is some am radio sound recorded from my laptop's soundcard whilst surfing twente university websdr.

Two octaves of a thick heavy bass stab with reverb. [format: wav][license: cc 0].

4-channel record of a rolling thunder. The record is slow downed to 0,7-speed. The thunder has now very deep frequencies, which can shake your house, if you have the right equipment to play the file. The 4 channels are recorded in irt-cross technique (microphone distance 25cm) so it is a 360° record. Http://irt-cross. Mozello. Deat the end of the track the rain moves to the front channels. (fade is starting at 1:20 min and is finished at 1:41min)my other track can be used for "intro" followed by this track. See/hear here for the intro option:https://freesound. Org/people/bluedelta/sounds/446753/. The spatial impression is best if headphones are used. Ch1 = flch2 = frch3 = rlch4 = rr. The download-file is a polywav. If you need to split the file (e. G. To make a stereo file), you can use the easy to use"wave agent beta"(free)from sound devices for example. ;-)_________________________________________________________used recording gear:zoom f84 x rode nt1 (without "a" = the black ones).

Made from a tom drum i created with xfer serum in reaper. Rendered the instrument as audio, then, sampled a small section of the tom and looped it infinitely to create a static frequency. Then i added the reapitch vst and created a smooth automation curve down to -24 semitones. Lastly, i added a short fade in and long fade out.

Sampling the afm (advanced fm) operators of yamaha sy99 synthesizer. My purpose was to recreate the waveform shapes mathematically in serum formula parser.

This sound was designed for an opera production as to simulate an earthquake. It is combined and remixed from various different free sounds.

500 hz tone or 500 hz sine wav sound effect. Ear piercing.

Lofi radio sound recorded with 3 eur cheap radio unit. Recorded with tascam dr-22wl. ---in case you use any of my sounds, i will be happy to be informed, although it is not necessary. Recorded in 2018.

Using a variety of 1980s radios connected via a headphone output to the computer, i tuned in - across the entire bandwidth - of the mw and lw channels. I also captured the static hiss of those bands, 'dead air'. There are small clips of various stations along the way but i was looking for that 'tuning in' sound that was so familiar when radio was the central part of every teenager's life.

I foudd this frequency, between 4450 and 4475 khz whilst going through channels on radiosdr. Org. It sounds a bit like a printer and then lower down sounds like a laser. Sorry for the sound of me pressing the keyboard, my laptop has an internal microphone so this was picked up.
