1,920 Royalty-Free Audio Tracks for "Frequency Modulation Synthesizer"

This is a sound made in audacity with a high frequency square wave slowed down. I have a question about this effect that sounds like a robot saying ''uaiuai'' ¿which is the name of this effect?if someone knows the name, please comment.

A soft static hiss from somewhere on the radio dial.

This low rumble was first created to represent an airplane.

Flip across the am radio dial through a range with some high-pitched sing in the static (and intermittent indistinguishable voices).

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.

A series of wok hits, lowered into water. Gives an acoustic sounding dizziness and frequency shift. Could be good for comic style animation or theatre.

Sonido echo para llamar atención ya que es disonante, como las uñas sobre un tablero.

Spooky ∴ ambient ∔ drone.

Static with a sort of jackhammer pace at 107. 9 on the fm side of the radio dial. Recorded from a digital tuner, with a quick flip to 87. 5 fm then back to the 107. 9 static. Definitely qualifies as noise.

A close recording of a ringing ride cymbal. Useful as a drone or feedback-like ringing. All my sounds are fully free to use, but please consider leaving a comment to let me know how you'll be using them. Just curious! :).

3 recordings of various rfis made by refreshing the radio signal on myphone and putting it close to my microphone. First sound however, was coming from my electric piano, because my phone was on top of it.

Moving a lane on a grid.

Electronic generated sonic object non human female voices modulations sample 1.

Polyrhythmic synth sequence. Exploring with ring modulation.

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!.

Long Trail (computer generated) "A lazy meditation on the long, hot road ahead."

This sound is an audio file that slowly breaks up the further it is played. I recorded this with an in-built microphone, no idea what make though. I recorded this on audacity, and added gradual distortion. Warning: you may need to turn down the volume for the last 6 seconds!.

A very high pitch noise from ddlc.

This kind of noise randomly generates the values -1 or +1 at a given rate per second. This number is the frequency. In this example the frequency is 100 hz. The algorithm for this noise was created two years ago by myself in c++, as an imitation of noise generators in supercollider 2.

This kind of noise generates sinusoidally interpolated random values at a certain frequency. In this example the frequency is 100hz. The algorithm for this noise was created two years ago by myself in c++, as an imitation of noise generators in supercollider 2.

Recorded in a tram in tokyo. I didn't use high-pass filter when recorded, so i think you can hear much low frequency. Sennheiser mkh20 and fostex fr-2.

The interference produced at the low (left) end of the radio dial on a jambox set up close to a dvd burner while in operation. Sound rises and falls as the burner writes to disc.

This was produced by tapping on a stethoscope which had an earbud pressed against a shure sm57 mic. Low pass filter applied, as well as compression and a gate. Chorus added. Used a recording cassette deck as a preamp going into an m-audio audiophile usb soundcard. Note: if you're having problems listening to this clip, the cutoff frequency of your speaker set may be too high(solution: new speakers). The signal strength exists almost entirely in the very low frequencies, so you may need a sub-woofer to hear it. Otherwise, try turning your speaker volume all the way up. Doing so may saturate the signal and at least allow you to hear the harmonics of the signal caused by the distortion. I don't recommend it, but you'll at least maybe be able to hear something.

Re-edited sound of file 273410. Lowpassfilter / hi-cut above 60 hz and cutted sub frequencies below 60 hz. Postproduction and editing with sony soundforge, 2015.

Radio frequency tuning noises.

Sound of user dobroide modified octave downhttps://www. Freesound. Org/people/dobroide/sounds/19368/.

A recording and manipulation of radio am frequencies.

Static with pops from dead air on a radio station. Starts with a drone which fades from the background.

A very harsh section of static with periodic interference (source unknown) from the far right-hand side of the fm radio dial, at 106. 7 mhz. Recorded from a digital tuner.

A less harsh, almost tickling of static pops from the right-hand side of the fm radio dial, interspersed with harsh interference (source unknown). Recorded from a digital tuner.

High-pitched flip across the am radio dial. Good intro-type recording.

A metal key attached to a magnet with its handle only. The key bounces back and forth, when pulled back and released, and produces a nice metallic sound.

A modulated bass guitar sound.

A modulated high frequency synth created using eq and vol automation un-filtered.

High frequencies repeted sound (sound design in protools).

A simple sine wav with frequency changing according to a parabola.

Static from a radio station wireless remote.

No, i cant really describe what this is! but i use a ring modulator. Two audio signals goes in. I guess the side band frequencies goes out??? or?! anyway the original frequencies are also in the mix. So, two audio signal and the result from a diy ring mod. Have to learn more. . . Read below!!! in this sound you are listening to, the result, the ring modulation, carrier signal and modulator signal. After some research. . . I write this for myself. . . Correct me if i'm wrong!!!from youtube (audiocollage)ring modulation is the sum and the differences of the carrier and modulator signal. Feed the ring modulator with 261,626hz and 391,995hz and you get (261,626 + 391,995) 653,621hz and (391,995 - 261,626) 130,369hz. From wikipedia". . . Neither the carrier nor the incoming signal is prominent in the outputs, and ideally, not at all. "". . . In the basic case where two sine waves of frequencies f1 and f2 (f1 < f2) are multiplied, two new sine waves are created, with one at f1 + f2 and the other at f2 – f1. The two new waves are unlikely to be harmonically related and (in a well-designed ring modulator) the original signals are not present. It is this that gives the ring modulator its unique tones. ". Above is true when using pure sine waves! waves with no harmonics. I have a passive diy ring modulator. I guess it's not acting "perfect". . .

Remix of wierd chimes. Wavhttp://freesound. Org/people/kwahmah_02/sounds/250253/which was a recording of a shortwave broadcast in am mode received in usb mode 1khz off frequency. I used goldwave's mechanize feature at 10000khz, then applied low pass filter at 10000 khz to filter out the newly created upper sideband, then i used mechanize again at 9000 khz, which tuned in the recording just like if i had a tuneable receiver.

Simple patch. Two oscillators, ring modulation, lfos, vcas and digital effects. No spring reverb this time. Important module is the clock divider. Result a generative ambient patch and sound.

Simple patch. Two oscillators, ring modulation, lfos, vcas and digital effects. No spring reverb this time. Important module is the clock divider. The oscillators where tuned to the same tone one octave apart. Well. . . Not exactly. After having recorded i measured the frequencies 228,8 hz and 117,7 hz. . . But that made the output from the ring modulator interesting. What is generative with this? i modulate amplitude of the sounds and the decay for all thee sounds. This also affects the rhythm sound.

I have made a pastiche (sw. Pastisch) on a simple track i, for one reason, like.

A drone resting in chaos and ring modulator circuits.

Very strange sounds from a very high frequency.

Here is a sound that i produced in audacity by generating a tone and making the frequency very low. It sounds rather like a humming of a machine or electrical appliance! good for looping and such. Enjoy !.

More modular synth sounds. My sounds. Found the tag "sound-poetry". What is that? have to search.
