80 Royalty-Free Audio Tracks for "Variability"

This is the variable mid/high pitch sound of a metal door not properly closed in my college, making a whistling sound. There are very light sounds of people passing and chatting by the door. I used this sound in a group project as part of a night wind sound in a dark forest. It is looping. Recorded with a tascam dr-40.

Variable quality as recorded on phone, walking on a sandy rocky area around a reservoir. Nowhere near the sea actually.

Sounds nice to me. Variable tempo. Made with analog modular synth.

Removal of lid, and switching on and off an electric trimmer/razor with varying modes/speeds.

Hey everyone!. Feel free to use this sound in all your projects. Thanks!.

Filtersweep with the sequential ob-6 sem-state-variable-filter. C1. Rme babyface pro fs.

Siren effect with digitally controlled frequency sweep using 96khz crystal controlled oscillator, 8-bit binary counters set up as a variable frequency divider. I added slight reverb.

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.

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

This sound effect was created using beeping effects and then used a audio flanger to create the effect, 200 mili seconds variable delay, 0. 200 hz and a fixed delay of 100 mili seconds.

Large cardboard box falling onto ground. Edits into one-shots. Stacks with other from bundle into a good crash. Recorded with shure ksm32 and buzz audio arc at 24bit and 48khz. Requires editing.

This is a pack of 20 synthesized snare sounds with different "variables" for varieties. Wave forms slightly differ as well as the cutoff frequencies, resonance, and noise lengths are all slightly different from each other.

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.

Variable speed on main trigger. 4-step shift register made with sample and hold modules. Looping envelopes with varying speed. The sample and hold shift register does not preserve pitch frequency very well.

Using a sharpie marker pen to write and scribble on a piece of paper. Writing, a few dots to punctuate writing a sentence, drawing a heart then scribbling inside the heart shape to fill it in. Scribbling different speeds. Recorded on a zoom h1.

I built it because i could. It is fitted with gliding linear slide carriage bearings, has a counterbalanced offset crank with needle bearings, a jackshaft to drive it from a variable-speed dc motor, and even a variable stroke length (which was tricky). Above all it has something i haven't seen in any of the machines one can buy, a bendable, collapsible coupling that would prevent injury to whomever is on the receiving end of the stroke. Clearly it will never be placed into production as it would cost too much to sell at a typical consumer price level. May all be for nothing because i can't get anyone to let me try it out, and i'm only accepting female applicants from among people i know. It's my machine. Sue me. This file is a 30-second-plus repeat of "v1-reciprocating machine. Wav. " downloading that file and using the repeat feature in audacity will generate any length file you please.

Gem pathescope 9. 5mm projector, unit #1191, made in england. Recorded on a marantz pmd661 with a rode nt4 stereo mike. The gem is a variable speed projector, controlled by a rheostat.

Little school pencil bag full of pencils, pens, sharpeners, rulers and other stuff. Sounds are surprisingly variable and could be used not for just bag bust also for layering audio for weapon reloading for games. I finally decided to begin uploading sounds here (so those are my very first sounds here)those are old recordings which i've done about 2-3 years back on my phone for personal projects, before i've got decent recorder, those sounds are the best sounding among the others. To be honest, they sound surprisingly well, considering that those recorded on average phone with huge noise floor.

An internal gas combustion engine starting up, and then cutting grass as it moves across the lawn. The clip is recorded from an elevated vantage point about 25 feet directly above the lawnmower. In the background some lawn debris can be heard hitting the blade and getting tossed. The variable pitch motor slows as it encounters heavier grass. It is the first grass cutting of the season and, being on the west coast, the grass is very thick with moisture enhanced growth. The recording is made with a high quality stereo zoom h1n portable audio recorder. However, the. Mp3 setting was selected during recording to achieve a smaller audio footprint (for another use), melded to a mono channel, then exported to. Wav as the preferred format for this repository.
