Re-edited sound of file 273410. Lowpassfilter / hi-cut above 60 hz and cutted sub frequencies below 60 hz. Postproduction and editing with sony soundforge, 2015.

Sound of user dobroide modified octave downhttps://www. Freesound. Org/people/dobroide/sounds/19368/.

A recording and manipulation of radio am frequencies.

Static with pops from dead air on a radio station. Starts with a drone which fades from the background.

A very harsh section of static with periodic interference (source unknown) from the far right-hand side of the fm radio dial, at 106. 7 mhz. Recorded from a digital tuner.

A less harsh, almost tickling of static pops from the right-hand side of the fm radio dial, interspersed with harsh interference (source unknown). Recorded from a digital tuner.

High-pitched flip across the am radio dial. Good intro-type recording.

A metal key attached to a magnet with its handle only. The key bounces back and forth, when pulled back and released, and produces a nice metallic sound.

A modulated bass guitar sound.

A modulated high frequency synth created using eq and vol automation un-filtered.

High frequencies repeted sound (sound design in protools).

A simple sine wav with frequency changing according to a parabola.

Frequency modulation tone of a modular synthesizer.

Static from a radio station wireless remote.

Radio frequency tuning noises.

Here is a sound that i produced in audacity by generating a tone and making the frequency very low. It sounds rather like a humming of a machine or electrical appliance! good for looping and such. Enjoy !.

A sound made for a project a few years back to sound like the whirring sound of a wind turbine.

This is a transformation of the original recording https://freesound. Org/people/pinehadmz/sounds/369501/. For week 10 "musical piece" assignment for the audio signal processing for music applications online class. There are three layers, panned in stereo. Each syllable of each layer was randomly pitch shifted to a note in the minor scale using the harmonic plus stochastic model. Each harmonic track was thickened with extra harmonics during the synthesis process too to make it extra weird.

A wet finger rubbing on the outside edge of a crystal wine glass.

Crackle and popping from an ego one vapor cigarette device.

My heartbeat, recording with low eqing and a shure sm58. There's some moving of a microphone and a little bit of breathing. Towards the end i take a sample of my computer.

Interference is a interesting phenomenon. I blow a bass tone and add my own voice, first i adjust my voice to same wavelength as the instrument, then i change my voice linearily, and you can follow how you get a 3rd tone, which is either a+b or a-b.

Poorly tuned am station with several signals battling to come through at the 1600 khz setting.

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.

Abstract, ascending "tone"- one oscillator frequency modulated by a sample and hold module- done using synfactory/studiofactory software.

Recording of an empty radio frequency.

Nighttime radio static at the am radio band setting 1400.

The jumble of competing distant signals at night at 1290 on the am radio dial.

Low frequency waveform.

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.

As a homage to freesound. Org for being a member for over 7 years under the name "djeuphoria", i present the freesound community with some unique sounds i've created recently using loads of different plugins and synthesizers that i've been acquiring over the years that has slowly turned into a massive collection. So with that being said i'm going to be periodically adding sounds to my "dream sample pack" so you can all hear the sounds i've been creating under my new nickname "dream", thank you all for the downloads, its awesome to see how terrible my sound quality was and how much i've improved from that, enjoy these awesome synth sounds i've engineered, cheers. -dreamp. S, most of the melodic sounds are recorded in the key of c for convenience and all foley sounds are recorded with a zoom h4 at 44khz.

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. . ;).
