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

I feed 2 lfo sqr-wavs to a vca. Now you can get 3 levels of cv.

A recording of myself doing some "creative tuning" willy-nilly around the available spectrum of "websdr at raf hack green", 3/11/13; trying to keep things interesting, yet not lingering too long anywhere in particular, and avoiding rather than seeking intelligibility of the various broadcasters. Some bits reminded me of ben burtt's "droid/alien chatter" material.

Again polyrhythmic. . . But slow. Exploring with ring modulation.

Polyrhythmic adventure with a bassdrum. Exploring with ring modulation.

A sound made for a project a few years back to sound like the whirring sound of a wind turbine.

Something i accidentally got while messing around with voxal voice changer by nch software. It was a background noise of my mom closing a door, and i decided to put it in reverse and i couldn't help but notice that it sounded like a low "whoosh" transition. So i opened it in wavepad and added echo + reverb and voila.

This is a transformation of the original recording https://freesound. Org/people/pinehadmz/sounds/369501/. For week 10 "musical piece" assignment for the audio signal processing for music applications online class. There are three layers, panned in stereo. Each syllable of each layer was randomly pitch shifted to a note in the minor scale using the harmonic plus stochastic model. Each harmonic track was thickened with extra harmonics during the synthesis process too to make it extra weird.

A wet finger rubbing on the outside edge of a crystal wine glass.

Crackle and popping from an ego one vapor cigarette device.

My heartbeat, recording with low eqing and a shure sm58. There's some moving of a microphone and a little bit of breathing. Towards the end i take a sample of my computer.

Interference is a interesting phenomenon. I blow a bass tone and add my own voice, first i adjust my voice to same wavelength as the instrument, then i change my voice linearily, and you can follow how you get a 3rd tone, which is either a+b or a-b.

These sci-fi synth sweeps were created by manipulating white noise with filter sweeps and other effects and then using noise reduction to remove the underlying white noise. You would need to pick through them and cut them up, but they can be useful for sound designing light graphic elements that move around and animate on and off.

Poorly tuned am station with several signals battling to come through at the 1600 khz setting.

Low pitch static which reminds me of 1950s sci-fi television. Created by filtering a static wave from an analog radio then slowing the pitch and adding a mechanization effect.

A short sound sample of keys being handled causing it to rustle.

Abstract, ascending "tone"- one oscillator frequency modulated by a sample and hold module- done using synfactory/studiofactory software.

Recording of an empty radio frequency.

Nighttime radio static at the am radio band setting 1400.

The jumble of competing distant signals at night at 1290 on the am radio dial.

Low frequency waveform.

Playing around with the excellent tuner at http://websdr. Ewi. Utwente. Nl:8901/. The website even has a recording button! this version is the same as "shortwave-sweep-and-beeps. Wav" except here i have limited it with a threshold of 10db, which decreases dynamic range but also makes it louder overall.

Pounding the back wall of a uhaul truck cab from the inside with my fist. Sounds great when you add reverb. Recorded with a tascam dr-40.

The sound effect of 75 hz on a yamaha keyboard.

This kind of noise generates linearly 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.

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

Samples i made with my korg volca fm.

I created a sinusoidal sound of frequency 200 hz and amplitude 0. 4. I played with the sound envelope on the sides and the middle then i repeated it to create a radioactive sound.

I like to listen to static (often actually) and it actually shifts a lot through out the day. So i heard some cool ringy stuff. . & decided to sweep through the am band. . . And actually touching the screen of my cell made the static louder. Sounds like a synth.

126. 5 bpm loop made from ultra-high-frequency glitch noises. Weird fun interp artifact tones at increased speeds.

Requested sample for a flip across the radio dial. This is on the am side.

Tuning / moving tuning dial on an am radio (australia). Use for whatever you want!.

Hm. You know, use this however you want, because i'm bored of getting credited everywhere. (nice opinion, eh?).

A low freq sine wave drop.

Freq mod laugh synth 1 //cc0.

Playing with a couple of small high frequency bells around the mic.

A plate was placed on a table with a very small height gap so that it vibrated when flipped with a finger. Produces a sound similar to a ruler pushed down on a table, flipped and pulled onto the table. It's a bit difficult to describe but if you hear it, you see what i mean and i'm sure you've done it as well. . ;).

This is the sound of brownyan noise, made with audacity program. Stereo of this noise created with amplitude at the default value, also with fade in and out effects added for the good results. Using headphones is the best way to hear low frequencies of this noise. Also this sound can be use for tinnitus problems or masking unwanted noises. Also, it's very effective for relaxation, sleep or meditation. Enjoy it, and download this is recommended due to the bad quality preview.

Arp 2600 high freq pad.

This is the sound of the fire alarm that is inside my graduate housing complex. It is very loud. Recorded on an edirol r-09.

Playing with ring modulation on my modular. Zapp!.

Low and hi frequency larsen effectsrecorded with rode ntg2 connected to motu ultralite mk4.

Here's a low volume, low frequency noise recorded during an acoustic survey of a condominium to identify a sleep-disturbing noise. It is primarily a combination of 13, 18 and 23 hz (5 hz steps). Not audible on computer speakers, it should be listened to on closed back headphones or very good quality sound system.

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

Yet another "low, bassy thing". Will sound better once downloaded as the preview function sometimes adds compression artifacts. This one is loopable and might produce a mildly stupefied mental state in some listeners. So if you go and load it into your ipod don't try operating a vehicle or playing with power tools.
