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.

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

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.

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.

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).

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.

alien frequencies preset #01 from spherator fm synthesizer vst vst3 audio unit frequency modulation synthesis (windows / mac).

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

Lowercase clicks. Minimal. Subfrequencies.

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.

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.

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.

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.
