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

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

Buzzy patch of static from the am radio dial slowed and with a filter and some digital reverb.

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

Played with shaping low-frequency noise and speeding it up, made a nice, usable cymbal. Will also upload original speed.

This second sound is a recorded sound of a bike chain, i modified it using some effects :1-normalize2-wahwah effect with-frequency = 3. 3 hz-start phase = 0-depth = 70%-resonance = 2. 5-wah frequency shift = 30%3-melt closingthe final sound gives an impression of a sound under water.

Sweeping through frequencies of an old analogue radio, german radio stations. Recorded with tascam-dr40.

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

I created this sound with additive synthesis ,using different eg`s and five different sounds for low ,middle and high harmonics. The pluck noise is a filtered noise at the resonance frequency of 523 hz.

Radio switching frequencies with lots of static and radio noise. Recorded on edirol r-09, 48k, 24 bps. Free to use anyway you like!.

Static from the 810 khz frequency of the am radio band recorded from a digital receiver. Has a sort of submarine suggestive hollow quality.

Sweeping through frequencies with an old analog radio, german radio stations. Recorded with tascam dr-40.

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.

Recording of a bosch refrigerator. Recorded and processed at 24bit 96khz using the tascam dr-40 linear pcm recorder. Processing: gain-staging and soft high and low frequency filtering. No eq boost or cuts anywhere else.

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.

This helicopter sound design was created at fl studio, in the sytrus synthesizer. The sound consists of four layers. 1. Sine wave frequency of 44 hz. Simulates the low frequency noise of propeller blades. 2. White noise passed through the svf filter. Simulates the noise of propeller blades. 3. Saw wave. Simulates the sound of an engine. 4. The sine wave. Imitates a high-frequency whistle of the engine. Various modulations are applied to all waves through the envelopes of the synthesizer. Next, the signal on the mixer channel is processed by a multi-band exciter and equalizer. Then a signal was sent to two channels with delay processing. One of them imitates reflections. In the lower-middle frequency range. On the second in the upper-middle frequency range. As you approach the sound source, the volume parameters of the direct and reflected signals are automated, low pass filter, pan width and equalization of direct sound. The helicopter performs strange maneuvers, as if making constant circles during the approach to the listener. I did not seek to create the veracity of these maneuvers.

Buzzy patch of static from the am band of the radio dial. Slight flipping of the dial through the area adjusts the sound.

An old desktop computer running. Mic a bit too close to the ventilator and resting on the cabinet. High frequency hard drive noise clearly annoying.

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

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.

Created by cranking a filter to max resonance, adding distortion, then slowly sweeping the frequency control on a bit crusher.

Part of a shortwave radio teletype recording, made with a dx394 high frequency receiver. The signal is civilian, but could be used as a military sound effect.

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.

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.

A wind sound created with a white noise generator and a low pass filter on my console. I played with the cutoff frequency and a few eq peaks to vary the sound. Recorded at 44. 1k 16bit in stereo.

These sci-fi synth sweeps were created by manipulating white noise with filter sweeps and other effects and then using noise reduction to remove the underlying white noise. You would need to pick through them and cut them up, but they can be useful for sound designing light graphic elements that move around and animate on and off.

Clean recording of various sounds that would occur when maneuvering around an office space (specifically a desk) and manipulating common office objects. Recording features lots of paper rustling and sliding across a wooden desk, handling pens and a stapler, stuffing manila folders and plastic binders, and towards the end there are some sounds of small-medium sized personal bag being unzipped and zipped and then being filled with some of the office materials. Should work great for filling in general office noises in a scene or reinforcing actions that involve any of the materials featured in the recording. There should be enough variety to allow you to glean more isolated sounds or just use assortments of layered sounds. Recorded with an akg p170 into a tascam 208i audio interface at 48khz/24-bit. Microphone was positioned roughly 1. 5 - 2 feet away from the source. There is some slight room reverb present, which is intentional, and should match common office workspaces well. An 85hz high-pass filter was applied to remove any unintentional, unnatural low-frequency rumbling that may have been picked up during recording.

Built on 'synthetic kick drum' with the following differences:. - subtle spatial stereo addition starting from 105 hz- slight adjustments in individual frequency bands to emphasise sound characteristics- pink noise at below -68db for own frequency adjustments- additional slight warm coloration- sending the kick through the neold v76u73 compressor for additional subtle sound distortion without any compression.

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.

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

Dead air static with a "singing" hum at 103. 3 on the fm radio dial, with the volume boosted and slight effect added.

The sound of drilling (4 approach). Also short sound of start button (after the second approach). At the 3 and 4 approach you can hear hi-frequency whistle, it's a sign what the bit dull.

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.

Electromagnetic signal emanations from the power supply of a landline phone. Recorded with a small pickup coil using a tascam dr-05x.

Noise processed with various audacity effects until it felt like it could influence brain functions. Http://farm9. Staticflickr. Com/8070/8213683889_517a10ef52_o. Pngon flac and ogg vorbis audio file formats. Contact me if you have interest in specific sounds for open source or commercial purpose.

A minimal drone. Might need some eq-ing. The frequency analysis reveals an extreme graph. A both extreme and minimal sound. Will anybody download it?.

Removed the hum from cognito-perceptu's pill-bottle-4 sample. Original sample had truck in background in addition to some low frequency hum. Used the remove hum feature on izotope rx2 and, presto-chango, no distracting background noise. Now there is still a high frequency hum which i did not touch. I think this could be mitigated with a low pass filter in eq if you choose.

Seamless loop of gaspipe or gasleak hissing continuously. This sound is the actual background noise in the frequency range 1200 to 6800 hz from my randomly generated subhorrorambience1. Wav sample. All frequencies below 1 khz (lowend) and above 8 khz (highend) have been filtered out and the volume has been normalized. I release this sound as cc0. You can do whatever you want with it and don't need to mention my name. Tips & tricks for professional mastering of dark ambient loops:. ~ (range) 1200 - 8000 hz, the highmid area of all sounds. ~ (gate) filtering in and adding subtle noise in this frequency range can addatmosphere or "air" to dark ambience but sound noisy like a tape recording. ~ (filter) filtering out noise in this frequency range can make the bass andlower frequencies (20-1000 hz) in dark ambience sound clearer but more dull. ~ (highend) frequencies above 8 khz should always be filtered out completelyand muted to 0 db, since those are only necessary in music and higher sounds.

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.

Footsteps in wet coarse sand, close up, some steps in water. Little low frequency boom noise should be remove. France, 2009. Recorded with schoeps cmc6 mk41recorded on soundddevice 744twave mono, 16 bits, 48khz.

Radio scanner. Sfx conversion edited: adobe + fxs + mastered. Sound and loops freesound. Org/people/szegvari/. Musichttps://soundcloud. Com/user-174290723.

Some generative wildfire sfx made with sunvox. The crackling sounds were made by taking some highpassed white noise, ring modulating it with some more white noise, and then using a noise gate to usilate the loudest 'crackles'. The rumbling was created using lowpassed white noise, and the wind was made by bandpassing white noise with a high resonance and randomly sliding the filter frequency. Everything was sent into a reverb and a stereo expander.

Warning! loud noise! this sound is not intended to listen to, but to do technical measurements!. This is a test recording i made to measure my headphone's frequency response. It plays a nice "left" and "right" to determine the channels. Then it plays back white noise first in both channels, then one at a time. Then the same with sine sweeps. Then short impulses.

Noise processed with various audacity effects until it looked like stereotypical lips in the soundwave view. Http://farm9. Staticflickr. Com/8070/8213683889_517a10ef52_o.

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.

Recorded and processed at 24bit 48khz using the tascam dr-40 linear pcm recorder. Processing: gain-staging and soft high and low frequency filtering. No eq boost or cuts anywhere else. Also de-noised.

I don't remember making this, but i'm pretty sure all i did was run some white noise through bassboost a couple times. It works for earthquakes, distant tiger roars, and other subsonic sounds.

This is the sound that myself and others agree is what you hear when a loud noise makes your ears ring. Why this particular frequency? i don't know. It's just a simple generated tone--you can loop it to make it longer.

Chaotic resonances that soon falls into more and more chaotic behavior. Quite a smooth chaotic noise sound. Made from 2 sine oscillator frequency modulating each other and some variable controls. Programmed in chuck programming language.
