Low pitch static which reminds me of 1950s sci-fi television. Created by filtering a static wave from an analog radio then slowing the pitch and adding a mechanization effect.

A short sound sample of keys being handled causing it to rustle.

Recording of an empty radio frequency.

Low frequency waveform.

Playing around with the excellent tuner at http://websdr. Ewi. Utwente. Nl:8901/. The website even has a recording button! this version is the same as "shortwave-sweep-and-beeps. Wav" except here i have limited it with a threshold of 10db, which decreases dynamic range but also makes it louder overall.

Pounding the back wall of a uhaul truck cab from the inside with my fist. Sounds great when you add reverb. Recorded with a tascam dr-40.

This kind of noise generates linearly interpolated random values at a certain frequency. In this example the frequency is 100hz. The algorithm for this noise was created two years ago by myself in c++, as an imitation of noise generators in supercollider 2.

Something i accidentally got while messing around with voxal voice changer by nch software. It was a background noise of my mom closing a door, and i decided to put it in reverse and i couldn't help but notice that it sounded like a low "whoosh" transition. So i opened it in wavepad and added echo + reverb and voila.

The sound effect of 75 hz on a yamaha keyboard.

Synth talking with amplitude modulation.

Static from the 760 khz mark of the am radio band, with spikes to the high side of the tone and very little bass.

Samples i made with my korg volca fm.

I created a sinusoidal sound of frequency 200 hz and amplitude 0. 4. I played with the sound envelope on the sides and the middle then i repeated it to create a radioactive sound.

I like to listen to static (often actually) and it actually shifts a lot through out the day. So i heard some cool ringy stuff. . & decided to sweep through the am band. . . And actually touching the screen of my cell made the static louder. Sounds like a synth.

126. 5 bpm loop made from ultra-high-frequency glitch noises. Weird fun interp artifact tones at increased speeds.

Requested sample for a flip across the radio dial. This is on the am side.

Tuning / moving tuning dial on an am radio (australia). Use for whatever you want!.

Hm. You know, use this however you want, because i'm bored of getting credited everywhere. (nice opinion, eh?).

A low freq sine wave drop.

Grabación que representa el sonido de algun ser externo. Disonante como si fuera un rastrillar sobre un tablero.

Grabación que representa el sonido de algun ser externo. Disonante como si fuera un rastrillar sobre un tablero (recorded sound that simulates a hissing of a monster or a scratch of fingernails on a chalkboard).

Freq mod laugh synth 1 //cc0.

Playing with a couple of small high frequency bells around the mic.

A plate was placed on a table with a very small height gap so that it vibrated when flipped with a finger. Produces a sound similar to a ruler pushed down on a table, flipped and pulled onto the table. It's a bit difficult to describe but if you hear it, you see what i mean and i'm sure you've done it as well. . ;).

Arp 2600 high freq pad.

This is the sound of the fire alarm that is inside my graduate housing complex. It is very loud. Recorded on an edirol r-09.

This is the sound of brownyan noise, made with audacity program. Stereo of this noise created with amplitude at the default value, also with fade in and out effects added for the good results. Using headphones is the best way to hear low frequencies of this noise. Also this sound can be use for tinnitus problems or masking unwanted noises. Also, it's very effective for relaxation, sleep or meditation. Enjoy it, and download this is recommended due to the bad quality preview.

Low and hi frequency larsen effectsrecorded with rode ntg2 connected to motu ultralite mk4.

Here's a low volume, low frequency noise recorded during an acoustic survey of a condominium to identify a sleep-disturbing noise. It is primarily a combination of 13, 18 and 23 hz (5 hz steps). Not audible on computer speakers, it should be listened to on closed back headphones or very good quality sound system.

Ableton. Snare rim + arp with multiple ping pong delays. Transpose form +47 to -47. I just told you my secrets.

Yet another "low, bassy thing". Will sound better once downloaded as the preview function sometimes adds compression artifacts. This one is loopable and might produce a mildly stupefied mental state in some listeners. So if you go and load it into your ipod don't try operating a vehicle or playing with power tools.

Tuning the radio at some stations, it contains hiss and noise characteristic of old radios when you search for available stations.

Sine. Shape 1. 452. Relative frequency 210. 7. 60hz b-2-2.

Recording from the 590 kilohertz mark on the am radio bandwidth. Very typical mono static.

A choppy section of am radio static at the 1400 khz mark on the dial.

A short section from the 570 kilohertz area of the am radio band, static with obscured talk radio voices in it.

Section of am radio static with a high pitched sing in it, from the 580 kilohertz mark of the bandwidth.

H4n recording of an automated vibrating mirror surface at an art event. The vibration responds to the proximity of objects, thus the wavering in intensity. - i use this one a lot, i'd love to know what you do with it -.

A very low frequency tone/drone made with the studiofactory software synth. It's a cross-mod of the perlin tone generator with a formant generator. This is about as low and loud as my current speaker/amplifier system allows. Use with care i. E. Turn down your playback systems output before you play it. Final mastering was done with audacity.

A high-frequency electronic discord tone (sweeping from very high to high) suitable for ringtones and annoying dogs.

Great on subwoofer!.

Noise drone with high frequency sinusoidal sounds.

Sine wave, which amplitude and frequency are controlled by relevant dimensions of bezier curve. Mono 16bit, 44100hz.

Static from 750 khz on the am radio band, with a faint traffic report in the jumble.

Using a frequency filter by setting its oscillations in variable arrays i was able to make most of these sounds. Also vocoding and feedbacks and feed throughs were happening. Then they were altered in audacity.

Foley sound effect of sub frequency noises;. Sample rate: 48 khzbit depth: 24 bits. Mfma_sonic.

This is static actually coming from my radio but its plugged into the same cord as my tv & they are very close together. So it's actually interference. Also the proximity of my phone gives more sound (ringy static). That really awesome modulating sound is the moment between clicking the on button & the picture coming on the screen. 2nd try was better after i adjusted the tuner a bit.
