Small tractor.

A simple filtered sawtooth wave that sounds like a laser beam! updated version of "laser_sustained" to remove dc offset and normalize.

This krazy sound is made by lmms only. (osc-square, random arppeggiator play).

Sound for class.

Created in labchirp using a noise in a frequency of 440hz with bit crusher.

Switch on and switch off super8 meopta projector. Wav, 48khz, 32bit, zoom h1.

Simple uplifting sound, made on a rainy sunday. Try to use it in my trance music production.

Modulated pink noise. Software: pro tools / audacity / ocenaudio. Your comments are greatly appreciatedcheers, piotr zaczek.

Construction site, propeller-driven airplane passing, metallic impacts, some voices in the background.

Recorded with mobile phone. Edited in audacity. Let me know if you use it.

Sounds like a character is getting blasted backwards by some gnarly force !.

A modulated version of a bi-tonal vocaloid sound.

A fan - take 02.

A fan - take 01.

Roughly moving my mic to get this sound.

The sound of an audio cable going in.

This is what background noise sounds like when you, first set your recording to automatically reduce noise, except to get this sound, put mic on sensitive, then increase the volume. Voila! computer noise!.

General noise and chatter inside a coffeehouse in galeria krakowska, krakow, poland.

A recording made in the space between coupés in a train of metal rubbing against each other, making screeching noises; sounding quite melodic.

Train noise traffic road.

I`ve made a basic white noise using operator from ableton live 9and then i added some sidechain-compression to itthen i removed the low end so it does not interfere with other sounds in your track.

Rv7000 advanced reverb's feedback.

Static from the end of a public domain ephemeral movie. Reversed and folded to make it perfectly loopable for any length you need.

I took a bamboo backstratcher to the cage on my microphone. Recorded with a cad gxl2200 microphone.

Noise created by individual oscillators, using audio paint, with different height images, to demonstrate what happens with too few oscillators vs. Plenty. In the end, the result is not random enough to be noise. The first 2-second burst is pure white noise for comparison. Then we have multiple 1-second bursts from audio-paint in a sequence of different image sizes: 50,100,150,200,250,350, 500, 700, 1000, 1350, 1750, 2200, 2700, 3250, 3850, 4500, and 9999 (this corresponds to the number of oscillators). The last burst is longer, and there is 1/2 second gap of silence after the first (reference) burst and before that last (9999) burst. The images other dimension was 20. The spacing of frequencies was exponential, between 40 hz and 18 khz. This is not intended to be useful, just an illustration during a discussion in a forum (http://www. Freesound. Org/forum/sample-requests/35199/?page=2#post75605). As mentioned there, i realized only afterward that exponential spacing would be giving me an approximation to pink noise instead of white noise, so the reference burst at the start is not really a fair comparison. Ideally, i would go back and re-do all this using linear spacing, but that's a lot of trouble. :-) i did, however, change to linear to get a white approximation, but that's a different sound i'll upload separately (c. F. Http://www. Freesound. Org/people/zimbot/sounds/242053/). I don't believe you can get true white noise without at least something being random in your synthesis method.

Made by data-bending a video in audacity then re-recording the video with audacity.

Normalized background noise of an audio feed.

Filtered noise 50hz overtones and some other things going on.

Train sound, created on computer.

Tweaking a variety of knobs.

Ventilation, walla, elevator, residential hallway.

Variation of the first crackle sound.

White noise boom.

Annoying noise made by crashing infoscreen at bagsværd train station.

Recorded with the zoom h4n's inbuilt x-y capsules.

Office room acoustic.

Agarre lata robot.

Bolitas de icopor.

Lata cayendo.

Noise left after dithering and phase canceling a tone. A tone was created with audacity's tone generator. Another version of the tone was made by downsampling and dithering the original tone in ableton live. I then phase cancelled the two sounds by switching the polarity of one of the tones and blending them back together in audacity. Because of the phase canceling, none of the original tone can be heard. Only the noise added during dithering remains.

I recorded tapping a cup then applied various degradation effects.

A recording gone wrong, but right! strange vinyl/wind/scurrying type sound.

Calling the elevator. Then background noise of it moving.

Can't remember what i used to record this.

A bit of noise which resembles a snare drum if you squint.

Handling a megaphone.

Snare with noise mixed in and a lil eq automation.

A neutral, static room tone - with some reverb og distortion. I have used it in the background for radio shows, when recorded in a studio that's too silent - but of course mixed down a lot so you can just barely hear it.
