968 Royalty-Free Audio Tracks for "Frequency"

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

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.

Real recording of a distant train rolling on an old canadian railway. Ran it through a low pass filter to remove unwanted noise, gentle 12/oct slope. Use this for whatever you want, for free.

This is an example of a low-frequency sound often recorded through the hydrophone on the mars cabled observatory - an earthquake. Mars is located on smooth ridge (36. 7125n, 122. 1869w), west of monterey bay at approximately 900 m depth (http://www. Mbari. Org/at-sea/cabled-observatory/). This magnitude 3. 8 earthquake occurred on july 18, 2016 at 05:53:31 utc (usgs data). It was part of a small earthquake swarm along the san andreas fault, approximately 50 miles east of the hydrophone. All quakes in this swarm, with magnitudes as low as 1. 9, were detected by the hydrophone. We have recorded as many as 40 earthquakes within a single day. The original recording was normalized, and speed was increased 5x to make the low frequency sound more audible. Still, subwoofer or headphones are recommended.

This delta binaural beats is exactly 2hz apart and loop perfectly at 30s. Set at the low base frequency of 40hz and 42hz, it's a relaxing hum.

This sound is a smooth square with a 400 hz frequency and the amplitude is 1. I added a 2 echo with 0,6 decline factor. There is a fade of closing down studio.

Sfx - speaking into a zoom h6, removed various frequencies inorder to remve speech. Sound like a robot noise or alien noise.

Message 1-3 are captured by nasa, but recently even other countries have registered very strong, but short signals. The receivers are masers and the frequencies are in the higher gigahz range. Message4 was from russia.

Pipe organ c3 note (fondamental frequency = 261,46 hz, i. E. C3 minus 1. 1 cent of semitone). Organ stop named "montre 8". Recorded in france.

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.

At cmu, there is a building with a really long hallway that has amazing acoustics. In this experiment, i set up a feedback loop. On one end of the hallway, there is a microphone connected to a laptop. On the other end, there is a speaker connected to another laptop. The two laptops are connected via skype calling. I play with my speaker's built in eq, and play my violin to stimulate the resonant frequencies of the hall. A better set up would be to use better equipment directly connected to each other, and have a stand-alone eq to independently control what resonant frequencies are playing.

This is full sequence of music-box in tea can with screweing up(?) until full stop. It's gift-set of tin box with tea and onboard music box. First i'm winding up music box, put box on the table, then it plays until full stop. This audio recorded with sony mobile communications audio recorder (android) on nexus 4 in pcm wav. Then it was slightly edited with audacity - tiny noise reduction and equalisation (boost frequencies below ~400 hz, lowered frequencies higher than ~2500 hz).

Violet aka purple noise power density increases 6 db per octave with increasing frequency over the frequency range. It is also known as differentiated white noise, due to its being the result of the differentiation of a white noise signal. I created this by looping http://en. Wikipedia. Org/wiki/file:purple_noise. Ogg. Which is copylefted, however i claim that they can't be protected based on http://en. Wikipedia. Org/wiki/threshold_of_originality (check language sidebar on wikipedia page for other jurisdictions).

An artistic experiment searching for sound emissions and the limit of human hearing. Composed of infrasonic material that have a low acoustic impedance. Humans will be able to identify tones as low as 12hz. 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.

New linear scale. Made in python. . . 200hz up to 2000hz and back in steps of 100hzi'm not that convinced the beep command outputs exact frequencies. . . And the sound is terrible. But it is a beep. . .

The bass melody was produced by applying a modulation to the frequency of the bass. Not much has changed from 003.

Snare drum recorded stereo in shower close miked with sony pcm-d50. These are very bright. You might need to reduce the high frequencies.

Two shots of a hollow-sounding high-frequency short-delay flanger on a synth chord. First is firmer, second has more of a suck to the attack.

Radio noise: costant single note, then distorted by voice. Frequency: 21227. 50 khz. Recorded from twente university online radio tuner: http://websdr. Ewi. Utwente. Nl:8901/.

Frequency modulated diy oscillator, see https://youtu. Be/rpjbae6c3z0. Recorded using an iphone, through a cheap marshall ms-2c mini-amp. Cheap and smelly.

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?.

This sound was designed for an opera production as to simulate an earthquake. It is combined and remixed from various different free sounds.

Ambience field-recording in windy forest. I've made pseudo windscreen from my t-shirt :). Some mic rumbles on low frequency. Hp filter may help.

This is a recorded sound of keys scratching a fence. The different modification steps :. - phaser effect with the following parameters :phases : 15original/modified : 195lfo frequency : 1,5hzstartup phase : 0 degdepth : 100return : 30%.

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

Handy h2 zoom 4ch recording of supermarket checkout line. Hum is from refrigerator units nearby. Try using eq to rolloff the low end frequency hum of the refrigerator.

Sounds like rain. Made from crumpling tin foil. Should loop seamlessly. Boosting some of the lower frequencies (around 80 - 100 hz) should add some thunder for you.

Ableton. Snare rim + arp with multiple ping pong delays. Transpose form +47 to -47. I just told you my secrets.

Recorded at night-time in french countryside with usi_pro, lower frequencies partially cleaned up to phase out distant highway.

You can use this music in your videos. This sound was created with layering and frequency processing in dawbpm: 120notes: f d c# e.

Mono recording close up of water thundering down a weir. From the top of the weir - recorded with a sennheiser me66 onto a tascam dr4048kh wav with a little eq to add some to the lower frequencies.

A drumsequence for breakdowns or interludes with a lot of effects in it. If u like this, also have a look at my tunes: http://soundcloud. Com/beverlyhillsboy cheers!.

Some simple claps i recorded with an sm7b. Raw and fairly unedited. (some gain compression used to boost the low-mid frequencies. )great for layering on top of each other! -eg.

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.

Made with some noise from a recording and sampled 5 tones higher, has some nice low frequencies. Completely free to use, once downloaded it's yours.
