269 Royalty-Free Audio Tracks for "Frequency Modulated"

A 1500 Hz tone broadcast by WWV, the radio station of the United States National Institute of Standards and Technology.

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.

Frequency modulation tone of a modular synthesizer.

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

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.

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.

Made by fm synthesizer.

The static at various points on the am radio bandwidth from 1040 khz to 1220 khz. Recorded from a digital tuner so the switch from location to location is a cold chop.

I cut a few short clips from some of my projects to submit to a project that i had seen on the. Microsound mailing list. It's pretty fun to do this, i will try to garnish more goodies and share them with the world soon!. This is a short, textural loop with a slight click that makes me think of markus popp's music. It was synthesized completely using ableton operator.

As a homage to freesound. Org for being a member for over 7 years under the name "djeuphoria", i present the freesound community with some unique sounds i've created recently using loads of different plugins and synthesizers that i've been acquiring over the years that has slowly turned into a massive collection. So with that being said i'm going to be periodically adding sounds to my "dream sample pack" so you can all hear the sounds i've been creating under my new nickname "dream", thank you all for the downloads, its awesome to see how terrible my sound quality was and how much i've improved from that, enjoy these awesome synth sounds i've engineered, cheers. -dreamp. S, most of the melodic sounds are recorded in the key of c for convenience and all foley sounds are recorded with a zoom h4 at 44khz.

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

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

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

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

Cutted parts of an audio experiment using carbon electra saws with some internal pitch envelope going on, going into trash 2, going into eq modulation, going into manipulator (formant & pitch shift, a bit fm modulation on a shifting frequency at times), going into ott.

Dead air humming static at 103. 3 on the fm radio dial.

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

Signal from a poorly tuned a. M. Radio station on a digital receiver, so no waver to the tuning just the sounds of a distant signal capturing mostly interference from the ionosphere.

Accordion processed sample remix.

Voice processed sample.

Siren effect with digitally controlled frequency sweep using 96khz crystal controlled oscillator, 8-bit binary counters set up as a variable frequency divider. I added slight reverb.

5 second sine-wave (loop) generated in soundforge. 16 bit 44. 100 hz. Wav file. Part of a pack inspired by the "colundi everyone" poster. Free to use as you like.

A scanning sound for a scanning thing for in games, like a medbay scan.

High pitch sound.

Large high pitch.

Example of producing a beat frequency - two seconds of 110hz tone, followed by two seconds of 118hz, to form an 8hz beat frequency. Sound generated using the go-sound golang programming library:https://github. Com/padster/go-sound. As part of the demonstration program:https://github. Com/padster/go-sound/blob/master/runthrough. Go.

I needed just a piece of the "spark(fm_tri-90_sin-110)" for my next song. This is that little snippet. Thanks.

High pitched tv frequency.

Soft static hiss from the radio airwaves with a slight buzz in the sound.

Upward frequency sweep.

Sonido ritmico de sincopa alta con un tempo de 120.

Small synthesizer made in pure data.

A modulated bass guitar sound.

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

A low frequency hum that will work on pc speakers (at least it does on my pc). . - i made this sound because i needed a deep hum for a composition, but as it turned out my pc speakers cut off low frequencies. A quick googling taught me that this is common for many pc's, but also that there might be ways around it in terms of designing waves that the speakers can produce. And so, after playing around with audacity abit, i came up with this low frequency hum that works well for my purpose at least. - i hope it might help others with similar issues.

The source of this sound is https://freesound. Org/people/doomyd/sounds/530580/ - a clean electric guitar open a string. This sound has been processed using the harmonic plus stochastical analysis of the sms-tools package https://github. Com/mtg/sms-tools with frequency scaling and frequency stretching, to give a metallic flange & 2 octave bend effect.

Spooky ∴ ambient ∔ drone.
