723 Royalty-Free Audio Tracks for "Frequency"

I first generated a sinusoid at 440 hz with audacity, i then changed the pitch to f#/gb low and i applied a tremolo effect wetness 40% and a frequency of 4. 0 hz. We can also ear crossfades in and out.

Synthetic sound depicting the sound an old crt monitor makes when switching on layers:- thumb from power switching on- decaying bursts of hf noise- 15. 6khz electronic switching noise (squarish with lower frequency jitter).

A second attempt at a modern kettle boiling this time with the addition of a contact mike to give low frequency rumble to the sound track.

The A440 (A above middle C) tone, which is used as a general tuning standard for musical pitch. It is also broadcast by WWV, the radio station of the National Institute of Standards and Technology.

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.

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.

I made the vcf self-oscillate at a frequency of ca 270hz then i connected a sinus wave vco to cv1 and swept all the frequencies.

2 oscilators. One panned to the left the other to the right. Random pitch lfo bent on different rate speeds. With a bit cusher set to a certain amount, and mix to give both the crush and the original.

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.

Recorded and processed at 24bit 48khz using a rode nt1-a condenser microphone. Processing: gain-staging and soft high and low frequency filtering. No eq boost or cuts anywhere else. Also de-noised.

This is one of multiple samples i have recorded from short wave radio, and should, if i uploaded them properly be located in a pack of more radio samples. How the name is built up:sdr %yyyy-mm-dd%_%frequency% %description% (unfortunately i didn't get to put in the decimals of the frequency when i exported the samples t_t)i love you if you give me some credit, but it's not a must. Feel free to use it for whatever you'd like and by all means, link your work here so i can give it sum luuuuv.

An artistic experiment searching for sound emissions and the limit of human hearing. Composed of infrasonic material that have a lot of harmonic distortion. Humans will be able to identify tones as low as 12hz. From 1000 hz the auditory system decreases. Natural and human produced infrasonic sounds is anywhere, all the time. The artistic idea was to use background noises, signal fidelity, harmonic distortion, low-frequency in order to foster a soundscape of infrasound that travels through space. Made for project that was never released. Think somebody might enjoy or use it.

Artificial waterfall sound created using audacity. I created two brownian noise tracks and assigned one to the left channel and one to the right for a stereo effect. Using brownian noise means less high frequency noise that is harsh on the ears.

Raw sampled ieframe. Exe on a hungarian windows 7 64-bit computer using audacity. The reason why it's only 11khz in frequency range is becaue 44 100 hz makes the sample too high pitched.

A series of three octave tones dropping in pitch, with the highest one fading in to create a dropping effect ending at a higher frequency. Just my attempt to recreate the dropping bells effect. Start the sound over from the beginning after finishing.

Anyone familiar with circuit bent sounds will recognize something in this fake circuit bent production of mine. I abused bitcrushers, frequency shifters and god knows what else on my guitar recordings. . . I need another aspirin. >_>;.

This clean flame flicker was created by vari speeding a fast cloth flap, the wav was further processed to remove some low frequency. Please look at my website sfxmix. Com and contact me directly for you dialog cleaning and sfx/ foley needs.

A bionic man-like effect. Created in qtractor with calf organ and c* scape stereo delay. Processed in audacity to speed up velocity, added a tremolo inverse sawtooth effect to increase ducking at a frequency, and added fade in and out.

Our town was testing the sewers somehow using audio tones to measure something. Maybe resonant frequency or something like that. It sounded vey musical since they were using 3 tones per octave, like a scale based on an augmented fifth chord.

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.

Turning on radio reciver and going through fm frequency of few polish radio stations (for only few seconds). Can be used for background noice or transision for audio. Also lots of white noise plus click noice of turning on/off (begining and ending).

Exactly one complete wavelength of a 1-hertz sine wave. In audacity, you can use the repeat effect and then the change speed effect to generate any frequency. It is not meant to be a usable sound in its current form.

Opening a zippo lighter, lighting it, and closing the lid. Separated into separate actions, removed a low-frequency rumble from some of the sounds. Recorded in a small shed, zoom h2.

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 -.

Waves on a winter beach. It may be good for those who love nature ambiances. I used audio-technica bp4025 half plunged into my bag, which sometimes masks right channel. A distant ship makes slight low frequency hum. Korg mr-2.

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.

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'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.

Sampling the afm (advanced fm) operators of yamaha sy99 synthesizer. My purpose was to recreate the waveform shapes mathematically in serum formula parser.

Recreation of the red alert klaxon used in star trek - the motion picture and other original series cast movies. A square wave at the appropriate frequency, processed.

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.

I recorded the rain in brooklyn and wanted to make a blade runner kinda vibe for sleeping, there's a helicopter in there too, i threw in some low-frequency kinda whale/space ship noises.

Heard some cows across my street mooing at each other. They sounded sad and/or upset. Recorded on the zoom h4n. Edited in reaper to remove dead air/movement/excessive wind and eq'd some of the high frequency noise out.

For sound effect, or a bit of rhythm. I happened to record this sound without knowing after i had done some field recordings. I hope low frequency sounds abundantly on your devices. My small speakers don't. Recorded with at825 and fr-2.

This is a short and low frequency sound produced by an unfixed tile placed in front of the canteen of the upf campus poblenou. This sound was recorded with an edirol r-09 hr portable recorder placed close to the floor.
