349 Royalty-Free Audio Tracks for "Frequency Spectrum"

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.

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.

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).

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.

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.

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.

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

Frozen reverb with an ear-piercing whine.

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!.

Just messing around with radio frequency and stuff on.

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

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

Eerie transmission from outerspace.

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.

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 :).

Fizzle and hiss, together as one.

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.

Recording of cd/dvd-rom computer drive opening. Captured closing using a "telephone" pickup coil and a zoom h5 recorder. It's always nice to hear what projects you use these sounds for. Let me know!.

Ambience soundscape made in cubase.

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

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.

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

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

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

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).

“hailing frequencies open!”. Computer blip/chirp sounds, for all your science fiction game/film needs. Havefun.
