256 Royalty-Free Audio Tracks for "Frequency Sweeps"

Buzzy patch of static from the am band of the radio dial. Slight flipping of the dial through the area adjusts the sound.

Sweeping through frequencies of an old analogue radio, german radio stations. Recorded with tascam-dr40.

Free! really high annoying white noise. Use it for tv and/or high disturbed signal or whatever. Ripped, recorded, worked and mixed with audacity. (mp3 - 11:39 mins).

Dead air from the fm dial at 107. 3, volume boosted.

Could be used as moving sounds for something large or machine-like. Produced by manipulating this sound: http://www. Freesound. Org/people/soundcollectah/sounds/158479/.

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

Dl0ksc in cw qso of mar 10th, 2012, at 11. 50 utc on 10116 khz. Stable high frequency but multiple tone - spectrum. Audio frequency changes are due to my tuning of trx to hear multiple tone.

This is taken from (and an answer to) mxsmanic's "trip on métro line 9 in paris, france", at 2:20 exactly: metro on rails through the tunnel, which resonance creates this sound (very familiar to me as i live here). Interesting to notice that the sound's frequency stays around 483hz, which was (in the ancient solfeggio frequency science attributed to pythagoras) the frequency of "opening consciousness".

Created using lmms and the zynaddsubfx plugin with loads of automation on the filters.

Radio noise on short wave. Compilation of sounds.

Recording of the 560 kilohertz frequency of the am radio band. Has a high-pitched singing whine in it.

Noise with a lot of low frequencies.

Interesting interference sound made with analog modular synth.

This is a recording of very low frequency hum of a steel mill. The sample has been low pass filtered. The main frequency is about at 25hz. The sound was recorded some distance away of the steel mill area, where it mixed with other sounds as a constant hum, which could be felt in body too at certain spots.

Noise from a switched-off radio frequency receiver connected to an active recorder.

Experimentation with the harmmod m4l plugin in ableton live. No effects or post-processing was applied to the sound except normalization.

Heavy kick with a low frequency slide. Classic dance music phrasing fx for chorus to build/break transitions. [format: wav][license: cc 0].

Electromagnetic signal emanations from the power supply of a landline phone. Recorded with a small pickup coil using a tascam dr-05x.

Dual tone multi-frequency (dtmf) dialing 1-2-3-a-4-5-6-b-7-8-9-c-*-0-#-d in this order. Made with audacity.

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.

Are there a million of these sounds in film trailers? are there a million of these sounds on freesound? not sure. Started with 100k tone - pitched it down over time - it was too low, so then i pitched the whole file up a bit. Insert to make any slow mo sweeping matrix style scene look even more awesome. . . Or not.

Electronic snare sound made by an opl3 chip #1.

Same as "badass minimoog bass c7" but c4 note is played.

Buzzy patch of static from the am radio dial slowed and with a filter and some digital reverb.

Humming and whistling through my teeth, granulated and highpassed.

A white noise / sine wave noise.

Recording of someone reading psalm 118:1 on a really old radio.

Freezing rain recorded falling underneath a tree at night. Some unfortunate rumble from a nearby airport, could be eq'd out (or left in for something spooky!).

Turning on and off an old tube tv.

Appended series of different recordings of neighbours slamming their doors. Noise reduction and reverb applied.

911 dtmf dialing sound.

Sounds like it was a morse code sent by a human.

A sounds made with a microwave. High pitched sound looped 15 times. Enjoy!.

Noise processed with various audacity effects until it looked like stereotypical lips in the soundwave view. Http://farm9. Staticflickr. Com/8070/8213683889_517a10ef52_o. Pngon flac and ogg vorbis audio file formats. Contact me if you have interest in specific sounds for open source or commercial purpose.

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.

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.

Synthesized soundit's a regular sine with a fast, chaotic pitch modulation9 notes, first note on each octavesurge xt synthesizer.

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).

A high-frequency electronic discord tone (sweeping around high frequencies) suitable for ringtones and annoying dogs. Also suitable as a sound effect for 'sweeping the dial' on shortwave radio.

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.

Something for the acid generation. Loops perfectly, twisted in realtime, 113bpm, do what you want with it, enjoy ^_^.

Frozen reverb with an ear-piercing whine.

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!.

Just messing around with radio frequency and stuff on.
