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.
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.
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.
I played a bit with the filters and oscillators of a free vst synth. This sound is useful for cutting and applying different effects over it. I think that it can be used standalone as well.
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.
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.
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.
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 !.
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.
This kind of generates random values at a certain frequency. In this example, the frequency is 200hz. 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.
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.
Cicadas from hell. 6 pulse waves (cwejman vco-2rm, two audio frequency generators, and instruo cs-l), frequency/filter sweep modulated by e350 morphing terrarium. Overall frequency shifting by an e520 hyperion effects processor.
I foudd this frequency, between 4450 and 4475 khz whilst going through channels on radiosdr. Org. It sounds a bit like a printer and then lower down sounds like a laser. Sorry for the sound of me pressing the keyboard, my laptop has an internal microphone so this was picked up.
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.
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.
