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

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.

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.

Noise drone with high frequency sinusoidal sounds.

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.

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

Formatted for use in the make noise morphagene. This is the modulated and demodulated vocal track demonstrated in the video "demodulating signals with moddemix" available at https://youtu. Be/b3kt1fguq74.

A garbled sentence recorded from a ham radio repeater frequency in westchester county, ny. Recorded with a uniden bc75xlt, plugged into a scarlett 2i2 interface. Recorded with ableton live 10.

Radio frequency interference at the 1200 khz mark of the a. M. Band, caused by varying proximity to a laptop computer. Very active and obnoxious high-pitched static and squeals.

Recording taken from a train at about 20 feet away. It was very windy, so consequently, the majority of the track was very much ruined. There is a small click near half-way, caused by a brief release of steam. It might prove annoying if you are planning on looping it. There is also not an even right/left balance throughout, due to my movement to avoid the wind.

Low frequency boom sound, great to hear on subwoofer!.

Microphone tap with ambient sound and mid frequency larsen effects. Recorded with rode ntg2 connected to motu ultralite mk4.

Tried to create an earthquake-sound with sounds i have recorded with my zoom h5.

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.

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

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.

A cool and very much slowed down guitar note, recorded not long before my guitar broke (it was old and it cracked). I accidentally made it and i thought it sounded cool i guessit can be used for a jarring moment or a suspenseful sound or something like that. Im sad rn (´。＿。｀).

A long series of granular synthesis glitch-style oddness, could be used for interrupted transmissions, tuning in an old radio, galactic strangeness, and the like.

The famous delete! voice line from doctor who's "cybermen. ". I used voicechanger. Io to voice this. It would be recommended if you credit me for this, mostly to prove that this sound is voiced by someone other than nicholas briggs (voice actor for doctor who's cybermen and daleks).

I called it "industrial growl". This is an analog sample i made from an arp 2600 i had before i sold it.

Ringmodulated inversion of my speech from the file https://freesound. Org/people/kb7clx/sounds/648443/ invertedspeechcq. Wav. I took the raw recording and used goldwave's mechanize effect to translate my voice to a center frequency of 14khz. I then demodulated it first at 10. 6 and then 10. 2khz meaning that what comes out is essentially the opposite sideband, offset by 3. 4 and 3. 8khz respectively. 3khz just didn't sound as good. The first i filtered with a low pass of 2. 9khz, the second was filtered to below 3. 4khz to emulate a communications receiver passband. I am speaking upside down as described in this video. Https://www. Youtube. Com/watch?v=q_ykxzcbh-g beginning at 00:03:16. Being blind i can't see their diagram, but i've got my own by ear intuitive method, keeping in mind that oo and ee are farthest from each other, all other vowells get closer the closer they are to the middle of the human voice frequency range. I say: huhlay sue quee, sue quee, sue quee do ux. Cahlloong sue quee sue quee sue quee do ux. The ay in huhllay is like when a spanish speaker says béisbol (baseball). The a in cahlloong is like the a in cat if you're opening wide for the doctor. The oo is like the oo in book. Listen to the other file and you'll hear: hello cq cq cq dx. Calling cq cq cq dx.

Sound made by atmogen software.

Supersaw waveform.

Simple patch. Two oscillators, ring modulation, lfos, vcas and digital effects. No spring reverb this time. Important module is the clock divider. Result a generative ambient patch and sound. I recorded for 1,5h. The synth gave me some strange slow crescendo. Don't really know why. This is the last 30 min. Space drone sci-fi sound.

Sound / noise of a spraycan, good for hi hat as well.

This is an example of a low-frequency sound often recorded through the hydrophone on the mars cabled observatory - an earthquake. Mars is located on smooth ridge (36. 7125n, 122. 1869w), west of monterey bay at approximately 900 m depth (http://www. Mbari. Org/at-sea/cabled-observatory/). This magnitude 3. 8 earthquake occurred on july 18, 2016 at 05:53:31 utc (usgs data). It was part of a small earthquake swarm along the san andreas fault, approximately 50 miles east of the hydrophone. All quakes in this swarm, with magnitudes as low as 1. 9, were detected by the hydrophone. We have recorded as many as 40 earthquakes within a single day. The original recording was normalized, and speed was increased 5x to make the low frequency sound more audible. Still, subwoofer or headphones are recommended.

Static on the radio as a result of tuning a few channels down on an existing radio station. A voice is heard but their words are undecipherable.

A loop made from traffic sounds recorded at the broadway tunnel san francisco ca.

I cut a few short clips from some of my projects to submit to a project that i had seen on the. Microsound mailing list. It's pretty fun to do this, i will try to garnish more goodies and share them with the world soon!. This is a short, textural loop with a slight click that makes me think of markus popp's music. It was synthesized completely using ableton operator.

Base layer for sound fx compositions for space, deep sea, volcanoes, and so on.

The static at various points on the am radio bandwidth from 1040 khz to 1220 khz. Recorded from a digital tuner so the switch from location to location is a cold chop.

This is a 2 bar 120 bpm bassline with one dry and one wet play thru. The effect on the wet half is a simple filter morph, raising the cut-off on a low-pass filter thru-out the loop.

A recording made underneath a very busy highway overpass.

Arp odyssey low frequency damped sawtooth with random slight frequency modulation.

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.

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