723 Royalty-Free Audio Tracks for "Frequency"

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.

This is just a simple four to the floor kick drum pattern at 120 bpm. I created the kick itself by layering various synth timbres in rob papen's albino plugin. Processing was also applied such as compression, eq and using subtle distortion in specific frequency areas to get it sounding like this.

I have built a nonlinearcircuits sloth lfo, the regular version. Sloth is a chaotic lfo. The output is based on the lorenz system. It is a system of ordinary differential equations. It is notable for having chaotic solutions for certain parameter values and initial conditions. In particular, the lorenz attractor is a set of chaotic solutions of the lorenz system which, when plotted, resemble a butterfly or figure eight (very much from wikipedia). The sloth has two outputs x and y. Think of them as coordinate pairs. The output will probably never repeat itself but there is a pattern. I have built the regular sloth it usually takes approx 15 seconds to make a rough figure 8, one cycle in the “butterly”. Now i’m testing the module in different ways. In this sound i have connected white noise to a filter. The filter frequency is controlled by sloth (x output). In this patch i have set the initial frequency low. That’s why there is a low humming wind noise between the “tops”. The output sound from filter goes to reverb. The sound is more a study of sloth behavior than an attempt to create a great wind sound.

The filter frequency is controlled by sloth (x output). In this patch i have set the initial frequency at 12 o'clock. . . The output sound from filter goes to reverb.

Synthesized sound of a flying helicopter. The patter is as follows:. Sound 1 || sound 2 || sound 3 || sound 4 || sounds 1+2 || sounds 2+3 || sounds 3+4 || sounds 1+3 || sounds 2+4 || sounds 1+2+3 || sounds 1+3+4 || sounds 2+3+4 || sounds 1+2+4 || sounds 1+2+3+4 || sounds 1+2 again || sounds 1+2 with phaser effect (pitch up and down). Each sound above is exactly 2 seconds long except the second-to-last sound (4 seconds long) and the last sound (8 seconds long). All sounds synthesized in propellerheads reason's thor polyphonic synthesizer. Here's how i did it: used two oscillators (one noise oscillator and another multiple-wave oscillator), and then passed them through two different filters. In each filter, i lfo'd the frequency knob at 2. 0hz (120bpm), and the pattern you see above is each oscillator-filter combination muted in different ways. For the last sound, i applied a phaser effect and automated the frequency knob or some other knob to give that pitch-up pitch-down effect.

This is the stereo file of the 4-ch thunder-file--> https://freesound. Org/s/367222/. The thunder is slow downed to 0,7speed and has now very deep frequencies, which can shake your house, if you have the right equipment to play the file. ;-)the 4 channels are recorded in irt-cross technique so it is a 360° record. Ch1(left) = fl+rlch2(right) = fr+rr. _________________________________________________________________used recording gear:zoom f84 x rode nt1 (without "a" = the black ones).

I made this as a near ultrasonic sms signal. Created and edited with audacity, filtered with glame bandpass filter. If you hardly cut a pure tone, you introduce a whole lot of other frequencies to the signal at the cutting point. To avoid this after the cutting you need to filter the whole thing with a bandpass filter to ensure you have as little other frequency content as possible. It will audibly soften the start and the end of the sound. That's what i did here.

Using a variety of 1980s radios connected via a headphone output to the computer, i tuned in - across the entire bandwidth - of the mw and lw channels. I also captured the static hiss of those bands, 'dead air'. There are small clips of various stations along the way but i was looking for that 'tuning in' sound that was so familiar when radio was the central part of every teenager's life.

I say "ofishal in the mix" in a deep voice. The vocal sample is a response to the sample request "simple samples" by dj ofishal. Have fun with it! :). Recorded with zoom h2n handy recorder and audacity. Connect to computer with audio i/f mode. Recording mode: xy stereosampling frequency: 44. 1khz/16bitinput gain: auto gain, soloedited and exported to flac with audacity.

X and y comes from the nonlinearcircuits sloth lfo (regular version). X is the high sinus c, left channel. Y is the low triangle c, right channel. X and y goes to comparator resulting in a note when crossing the threshold. At the same time x and y goes to cv in on jupiter storm generating two glissando paths. The two used osc's on jupiter storm are tuned to the same pitch. The sloth have a potentiometer that is said to "alter frequency a little". . .

I initially created this snare using lmms ( linux multimedia studio ) and a single instance of the zynaddsubfx plugin. There were many effects and experiments done before exporting as an audio stem. Next i opened this stem ( single snare hit ) in bitwig studio and made a few copies of it and timestretched and chopped and then joined together in a group track the parts i liked to make the whole sound. Final effects included saturation, equalization , sidechain-limiting and compression.

Just tapping things around my desk with a screwdriver and jingling the loose change inside a glass jar. I had the mind to use all of the sounds in this file for a kick/snare/hi hat drum rack in ableton live - hence the ranges of frequency from low (jar thumps) to textured highs (loose change) and high (taps. ) i hope these come in handy, please enjoy! - vanszi.

What effects the color of the wave here on freesound? i could ask, but here is a little test. Part 1 - a (about) 60hz tone going from sinus to triangle (vcv-rack vco-2)part 2 - same tone. Sinus wave. An accelerating vibrato. Part 3 - now 2 tones. Same 60hz sinus tone plus another sinus tone slowly increasing in frequency creating beating effects. The second, rising, vco has a lower amplitude. All three part has the same peak amplitude (-4db)#colortest.

I was just messing around with audacity again, this time slowing down my recording like a tape record, which not only stretched the time, but also turned down the frequency range which resulted in pitch shift. I stumbled around a sound that sounded like a huge horn exhaust - like those war pipes from celtics. So i experimented a little bit and made this one. Original recording was mono (but recorded to stereo track), however i added a reverb effect which created a nice stereo reverb effect. Feel free to use in games :).

I used 2 low frequency operators (lfo) on a low pass filter (24db) on a generic pink noise sound with medium resonance settings, one of these lfo's was manipulating the other one with a random ramp, to make it sound more diverse and realistic. I put an aditional long envelope on the q (resonance) also, not to mention some chorus at a low tempo to make it kinda binaural with a stereo delay at a short time setting. . . I hope you enjoy it!.

Rain on a roof through an open window. Drops foreground are striking zinc very next to the mics. Other raindrops on the slate roof. Water falling from the gutter on a concrete floor further. Very nice thunderclap at 1'42"a low cut filter should be used to avoid some bass frequency in the wind. France, 2020listen also to "continuous thunderstorm" https://freesound. Org/people/bruno. Auzet/sounds/531041/recorded a few minutes before. Recorded with 2 clipy em172 in an ab setrecorded on sounddevice mixpre6stereo, 48khz, 24 bits.

This jump scare sound was created by playing 2 dissonant chords on a single coil telecaster mic'd up w/ a vox ac 10 amp. The two guitar tracks are panned left and right- reverb and delay are added. Additionally, frequency enhancers were added between 4khz - 6khz which adds a higher tonal energy in the upper range of the guitar. Gain is added which can be heard as signal noise mostly at the end of the clip. Enjoy. Bainmack.

I found two melodies in gis_sweden's excellent "you deserve it - friday randomness ii"http://freesound. Org/people/gis_sweden/sounds/362508/. And quantized them into a 92 bpm 4/4 thing. Each melody is presented panned, with and without a beat, then simultaneously. It's sort of an accidental counterpoint. I also messed up his nice analog sound into some harsh digital junk. There's a lot of high frequency energy here so watch it, and apologies to mr. Fletcher, mr. Munson and their daughter, curve.

A third version of https://www. Freesound. Org/people/gis_sweden/sounds/352940/. Now i let the alm pip slope affect a filter. I play a little sequence made with cvlfo , clock divider, attenuverter, quantiziser. The way i usually do…. But the interesting thing is the cvad (?) voltage controllable envelope generator. But in the case of alm pip slope you just control attack and decay. Seems to be enough. As in the other versions of this sound i connect one lfo to attack and a second lfo to decay. But this time i connect the vcad to control the frequency of a filter. Interesting. I wish i had two more cvlfos… should open up for rhythmical usage. I use no vca or adsr. I have connected the vco straight to the vcf and the vcf to mixer. In the beginning i have the frequency pot at 2 a clock then i gradually move it clock wise and let the vcad take control. 1 minute in the pot is fully clock wise. The vco is playing a sawtooth wave. If you dl and inspect the wave you can see that in the beginning and the end it is a sawtooth wave, but in the middle part the filter affects the wave form.

This is one coqui singing alone. The file was remasterize to eliminate other insects and noise sounds. Was recorded in the west of puerto rico island in the caribbean on june 19, 2022. A curiosity not too many people notice is that the individuals and species sing at different hours of the night and are affected by temperature and humidity. Rain increments the volume and intensity of frequency of the different species, some days one to 3 species can sing. Others you can hear up to 6 species in conjunction with other types of none arboreus frogs.

This sound i made with a python script. The script simulates a 2d-network of 13x13 identical masses connected with springs. I 'feed' one mass in a corner of the network with a 'chirp' of 400-2000 hz for one second and the system resonates at its characteristic frequencies. I 'listen' to the resonating system in the adjacent corner. The decay of the sound was build in, but the last half second i edited the volume to zero. The code took a few hours to execute. You may want to change the picture of this sound to the frequency-domain. Yo! awesome! nerd-pride! :-).

Recorded on a canon d550 camera. I live near a water tower built into a hill and firework displays cause a strange echo as the shock wave passes through. Listen to the first burst of bangs and there is a faint sound of "gravel falling into water". I suppose the frequency of the explosion is reverberating in the air gap in the water tower. There is a second burst of fireworks which are far away. Traffic from the a3 road is audible.

This was recorded while sitting in a closet during a tornado warning as a thunder-storm raged outside the house. It was recorded on april 28, 2020 in tulsa, oklahoma. There are several very low frequency booms from the deep thunder. You can hear the faint sound of tornado sirens blaring outside. There is also the intermittent sound of panicked breathing by one of the two dogs that were also riding out the storm, sheltered in the closet. A thunderbolt rattles some wood hangers on the hanger rod.

Recorded a short drum and bass loops at 120-bpm using ableton live 9. 4 notes per bar played on bass in this order: a1 f1 c2 g1. This recording is designed for a mid-range frequency instrument, like a guitar, over the loop.

This audio is not a sound effect itself, however it can be used with an impulse response plugin to recreate the acoustics of a particular environment. This particular file is designed to replicate the acoustics of distant muffled club or rave. This was done using the "profiler stereo lsp plugin" and placing the microphones on the opposite corner of the speaker in a highly reverberous house forcing the audio to reverberate around a corner. After this, a low frequency boost was applied in post along with other general cleanup of the audio.

This jump scare sound was created by playing 2 dissonant chords on a single coil telecaster mic'd up w/ a vox ac 10 amp. The two guitar tracks are panned left and right- reverb and delay are added. The delay tail you can hear oscillates between left and right speaker as it fades. Additionally, frequency enhancers were added between 4khz - 6khz which adds a higher tonal energy in the upper range of the guitar. Gain is added which can be heard as signal noise mostly at the end of the clip. Enjoy. Bainmack.

A pair of owls stationed themselves outside my half-basement bedroom window in colorado early this morning around 12am. Unfortunately i only had my phone to capture them with, but it still turned out alright, save for the periodic vox-like breaks when silencing background noise. The hoot is obvious as to the source, but i'm unsure about the screech/cry that occurs with equal frequency. Is it the response of a mate? or just the yip of a curious neighbor dog?. Recorded with the stock application on my lg g3 phone and encoded to mp3 using the "video to mp3" app.

Alchemical elements - sound experiences to compare. Hello sound-freaks,. In this pack i share some selected pieces of binaural beats referring to basic elements of ancient alchemy. If you listen, you should use headphone. I start with sulfur:. According to paracelsus (1493–1541), the three primes or tria prima – of which material substances are immediately composed – are:. Mercury (mind)salt (base matter or body)sulfur (spirit). (https://en. Wikipedia. Org/wiki/alchemical_symbol). Here some data for the sulfur binaural soundpieces i've worked with:symbol/atomic number in periodic table/nuclear magnetic resonance (nmr frequencies):s 16 7. 67 163,27 hz (176,01 hz: a series with this frequency may come later). You may listen to binaural variations of sulfur same nmr frequency 163,27 hz hz but different intervals:. Binaural creations of sulfur in these sounds on nmr 163,27 hzyou can read the distance to the core tone from the name of the soundfiles. For comparison with the basic or target tone, i added a sulfur stereo sound of 163. 27 hz as a audio test for you in this pack. Have a nice dayand fun with these compositions,the horst from germany. Some informations about sulfur as a homoeopathic remedy (if you are interested):. Https://www. Britishhomeopathic.

Warning: files can not be undeleted, not even by administrators!i re-uploaded the sound because there was an error connecting to the https://freesound. Org server. Estimated start pitch: a♯/b♭1 (59. 940 hz)this is an impulse of 59. 94 fps video (see why tv is 29. 97 fps and the horizontal frequency is 15734. 266 hz). I created this in audacity!. Silence: 1001 samples at 60000 hz, except the first sample is of amplitude 0. 25. Attribution is not required, which means that i, therandomsoundbyte2637, need not be attributed to use this!.

All in oneused filters are> doepfer a-124 special edition, the wasp filter> uoki-toki polivoks vcf> intellijel μvcfdidnt plan to upload this to freesound, but read this. Okay filter freaks. . . The frequency analysis reveals a peak around 20khz. Through all of the track? almost. What is that? (when i converted the file to mp3 the peak disappears. . . ) one clue could be that i use the filter as vcas too?i have applied normalisation, compression and limiter in audacity.

This is an alarm based on what we can hear here in huy, ben-ahin or anywhere near the nuclear power plant of tihange (belgium). I wanted a good quality recording of that but i didn't found it so i tried to remake that. ^^i will try to record that alarm next time it's the test. Here is a video (not mine) where you can hear the alarm test : https://www. Youtube. Com/watch?v=bvejbt-_d-4i used this sound : https://www. Youtube. Com/watch?v=akwne8eukcqwith some effects like convolution reverb of max for live or frequency shifter. I made that with ableton live 10.

Ambient echo sound. This sound required the combination of operator using the triangle wave and plenty of reverb. I layered this sound by using two different octaves to cover most frequency ranges that sounded best and to fill any gaps in the sound effect. This sound is inspired by scene transitions and wide shots where there may be a lack of other sounds so this frees up a space for a calm ambient sound that uses plenty of sustain and reverb. The triangle wave in the operator gave it more of a high pitched calm flowing sound. The other options for example sine wave sounds to harsh and sharp for this type of sound.

Start with chaos. In this sound/patch you have the possibility to enjoy chaos and feedbacki use my sloth lfos and jerkoff - another chaos moduleim possible sick i like this - thou its simple. Sloth modulate vco and filter cut of frequencyfeedback from vco to the filter via a vca controlled by a looping envpan fx also controlled by sloth - same env that controls the frequency. The "prassel" rustle sound is great in my earsjerkoff, exp vca, function and another sloth. Evaluation of patch/soundone cycle is - there are many cycles to consideronly short sounds - no, goodamplitude variation - yep goodpitch variation - mediumtimbre variation - some, via filter/two soundsmusical value - i think so!entertaining - yes?!.

Snippets from recordings of me playing the tanpura. The strings are tuned to b, d, g and e, so would work well in the keys of g or e minor. I noticed that my first pack of tanpura samples has a bit of fuzzy white noise so in this pack i have equalized - i reduced all the very high frequencies which got rid of most of the white noise without affecting the low frequency sounds of the tanpura itself. Please note this is the tanpura part of an instrument called the swar sangam which combines the swarmandal (indian harp) and the tanpura, it is not a traditional tanpura and does sound slightly different.

Alien xxx sent me a “cross modulation challenge”. I have tried to be true to his idea, but added automation, so to speak. Oscillator1 is constantly fm-modulating oscillator2. I vary the frequency of oscillator1 with an lfo. The output of oscillator1 is sent to a) left audio channel and b) in to oscillator2. The output of oscillator2 is fed to oscillator1. The degree of cross fm modulation is controlled by a vca controlled by another lfo. The output of oscillator2 is also sent to right audio channel. As i’m writing this i have just made a theoretical patch on a piece of paper. The result is what you hear. No effects added. Straight out of the modular for better or worse.

This sound was the result of a scary accident. I was looking at the view in the webcam of an open doorway leading into a dark hallway in my house, when suddenly this haunting feedback faded in and looped repeatedly, until i pulled the volume down. It was unexpected, and quite unnerving. I had to laugh about it once i realized what had happened. But that first moment had me expecting some ghostly apparition to come in from the darkness. Anyhow, it's just an accidental feedback loop. I've had it in my archives for about 20 years now. I thought it might be useful to someone else. Enjoy!.

Lazer sound. I made this lazer sound with the use of operator in ableton as well as adding a few effects to help round it out. I started with a basic sine wave and then began to adjust the frequency range to cut out some of the low end of the sound and enhance the high end to make it more realistic and movie accurate. I also had to shorten the decay time so it is more of a short zap sound than a prolonged note. Another step was giving it an initial high pitched sound and this was achieved by having the sound start higher up the scale with semitones and then dropping down giving the effect of shooting and something traveling from the source sound.

In this sample you hear a recording from inside a well sound insulated room, directly under the roof of a house. Strong rain hints the roof and produces low frequency muted sounds. In the background you hear the constant noise of the rain, coming through the window. There are also a few raindrops hitting the glass of the window. The sample was recorded using the built-in stereo microphone of a zoom h4n recorder. It was slightly processed to remove unwanted low and high frequencies which were not related to the actual recording. If you use this sound, please add a comment or send a private message what you created using it. :-).

I uploaded this after i finish my job (for scoring a music and additional foley/sfx) and by the time for cleaning, i found some of them were not used, were not even reviewed. I have several unused items. As i have benefited several times from this website, it's time to give back. Why not. This was recorded in my home studio, using my condenser microphone, the isk u99 (neumann knock-off, so the seller and a friend said to me; i wouldn't know however. ) powered by apogee duet preamp and simple shock-mount, i hope this recording clean enough for many uses. I recorded in close proximity, hence the high frequency a bit harsh. No edit. No effect. Cheers.

Its a sine wave folded 4 times by a cgs inspired wavefolder module (kinda like the metalizer from the minibrute). The whole thing is then modulated with an external function generator that controls amount and frequency of modulation. This is what came out and it's pure junky drone noises, so goddamn nasty. Absolutely love them. Feel completely free to sample this and use it for your own purposes. This is a diy synthesizer i'm building and unfortunately it is still a prototype, but i'm gonna finish it soon and hope to sell it. Cool indeed, isn't it?.

Layered synthesis of the sound of a big hit. 1 layer. Recorded sound of a blow to the pillow (take with a percussion tint)2 layer. Recorded sound of a blow to the pillow (double low kick)3 layer. Recorded sound of a blow to the pillow (variation of a low-kick double with a low pitch and a different attack phase)4 layer. The sound of a low-frequency sweep, like in a synthetic bass drum, obtained on a synthesizer. )an additional layer of metal impact (recorded by me) is not present in all variations of the sound presented. Each layer was subjected to quite extreme compression and equalization. A bit of overdrive is present. Well, convolutional reverb.

Recording of sea undertow on the beach of formicoli, vibo valentia, calabria, italy, the 19th agust 2022 16:44. The sound was recorder with a zoom h1n with windshield at a short distance from the crashing of the waves on the beach. The waves are driven by a light, gentle wind. The sound was recorded by holding the microphone in my hand while i dived knee-deep into the water and walk, filming the crashing of the waves (also on my legs). High-frequency sound details (the foam of the sea, the impact of waves on each other, etc. ) are much more audible here. Processing:* volume adjustment;* 120hz high pass filter (to reduce low some low frequencies rumble due to the wind);* cut and crossfade to eliminate very few mechanical noise of my hand on the mic;.

This sound was created as follows:. -zynaddsubfx free (and insanely amazing) software synthesizer generated simple g tone using a sine-wave adsynth engine- creative sbs 250 speakers played it back distorting the sound naturally and adding some interesting stereo phasing effects (is that caused by analog signal cable being longer for one speaker?)- i was manually changing the volume using the speaker's potentiometer (whitch is dirty and added some interesting noises on the right speaker, and also at peak loudness during the 54th second the right speaker is quiet)- the output was captured by zoom h2's rear mics- and recorded via usb into audacity free audio editing program- i exported the recording as 16-bit flac.

This is a recording of myself sleeping, beginning ~ 1:00 am local time (~ 3hrs after going to bed) on january 10th, 2020 (which i later discovered was a full moon). I was in the midst of experimenting with recording myself all night long out of curiosity, using a laptop placed near the head of my bed. This particular recording was the only anomalous one (the rest consisting mostly of just breathing or snoring with occasional sleep-talking). This ~2 hour recording has several interesting properties, which make it hard for me to believe that these sounds were actually going on while i was sleeping. On the other hand, i don't have a memory of editing this file if i did. Either way, i find it unsettling. I found the file in oct 2021 while organizing my samples. As far as i can remember, this is the original raw recording. On further inspection, i discovered that it has some additional peculiar properties that make it even harder to believe i could have made it without remembering doing so. The audio spans almost exactly 118min (7080s). There’s a frequency sweep with a cycle-length of 6480ms that repeats throughout the entire recording. Dividing the 118min by 6. 48min (60 cycles) results in 18 parts containing exactly 60 cycles and a remainder of 12 cycles.
