326 Royalty-Free Audio Tracks for "Frequency Jam"

Experimentation with the harmmod m4l plugin in ableton live. No effects or post-processing was applied to the sound except normalization.

Noise with a lot of low frequencies.

Dead air from the fm dial at 107. 3, volume boosted.

Could be used as moving sounds for something large or machine-like. Produced by manipulating this sound: http://www. Freesound. Org/people/soundcollectah/sounds/158479/.

Recording of the 560 kilohertz frequency of the am radio band. Has a high-pitched singing whine in it.

Dl0ksc in cw qso of mar 10th, 2012, at 11. 50 utc on 10116 khz. Stable high frequency but multiple tone - spectrum. Audio frequency changes are due to my tuning of trx to hear multiple tone.

This is taken from (and an answer to) mxsmanic's "trip on métro line 9 in paris, france", at 2:20 exactly: metro on rails through the tunnel, which resonance creates this sound (very familiar to me as i live here). Interesting to notice that the sound's frequency stays around 483hz, which was (in the ancient solfeggio frequency science attributed to pythagoras) the frequency of "opening consciousness".

Buzzy patch of static from the am band of the radio dial. Slight flipping of the dial through the area adjusts the sound.

Created using lmms and the zynaddsubfx plugin with loads of automation on the filters.

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

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

This is a part of the longer file "escalator hissing 1".

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.

Basicly the same patch ashttps://www. Freesound. Org/people/gis_sweden/sounds/395016/. I let it play for a while then i start "doing things". . . It's not beautiful but its what it sounds like when you playwith a modular synth. Think i'm done with this patch. Unpatching time.

Vcv rack #1 patch recording!.

Analog delay on fender strat through fender blues deluxe in bm.

I found a bunch of old piano improvisations i recorded on my iphone se. Enjoy;).

Freezing rain recorded falling underneath a tree at night. Some unfortunate rumble from a nearby airport, could be eq'd out (or left in for something spooky!).

Humming and whistling through my teeth, granulated and highpassed.

Recording of someone reading psalm 118:1 on a really old radio.

Are there a million of these sounds in film trailers? are there a million of these sounds on freesound? not sure. Started with 100k tone - pitched it down over time - it was too low, so then i pitched the whole file up a bit. Insert to make any slow mo sweeping matrix style scene look even more awesome. . . Or not.

Electronic snare sound made by an opl3 chip #1.

Dual tone multi-frequency (dtmf) dialing 1-2-3-a-4-5-6-b-7-8-9-c-*-0-#-d in this order. Made with audacity.

Same as "badass minimoog bass c7" but c4 note is played.

I don't remember making this, but i'm pretty sure all i did was run some white noise through bassboost a couple times. It works for earthquakes, distant tiger roars, and other subsonic sounds.

Buzzy patch of static from the am radio dial slowed and with a filter and some digital reverb.

Electromagnetic signal emanations from the power supply of a landline phone. Recorded with a small pickup coil using a tascam dr-05x.

A short clip from one of my original compositions. Audacity, yamaha synthesizer, zoom r8 portable studio and my gronked up brain.

Bass and drum loop - brand new bass strings - come get 'em while their hot.

911 dtmf dialing sound.

Noise processed with various audacity effects until it looked like stereotypical lips in the soundwave view. Http://farm9. Staticflickr. Com/8070/8213683889_517a10ef52_o. Pngon flac and ogg vorbis audio file formats. Contact me if you have interest in specific sounds for open source or commercial purpose.

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.

Sitting in a traffic jam that moves slowly. I recorded it with my tascam dr-05x.

Shit happens.

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.
