Aha! the wave form effects the wave color! here is a 60hz tone playing alternatly sinus and triangle wave. In this test im using vco-1. #colortest.

What effects the color of the wave here on freesound? i could ask, but here is a little test. Part 1 - a (about) 60hz tone going from sinus to triangle (vcv-rack vco-2)part 2 - same tone. Sinus wave. An accelerating vibrato. Part 3 - now 2 tones. Same 60hz sinus tone plus another sinus tone slowly increasing in frequency creating beating effects. The second, rising, vco has a lower amplitude. All three part has the same peak amplitude (-4db)#colortest.

Broadmoor hospital siren test. The broadmoor siren. Every monday morning at ten o'clock the deafening sound of an air-raid siren disturbs the peace over a large area of the leafy commuter belt that is berkshire, uk. The signal sounds the familiar alternating high-low note, followed by a constant all-clear note five minutes later. It's not a re-enactment of the blitz; it's a test of the escape alarm at the local mental hospital, broadmoor.

Test run of an air-raid siren in sept 2022. This happened the day after i got my tascam dr-05x so it was one of the first things i recorded.

Sinus wave connected to the filter cv1 in sweeps sound from mfb osc-03some reverb from ladik d-330.

Edited a default preset in bk-synthlab's free "vs-1 oscilloscope" synth and hooked it up with a free midi sequencer vst (hyperion) and placed thrillseekervbl on the master. This was done using headphones back then so the sound may not be optimal on some playback devices.

I made the vcf self-oscillate at a frequency of ca 270hz then i connected a sinus wave vco to cv1 and swept all the frequencies.

I've been working on a plugin for unity to allow users to create short loops from arrangements of other loops. Seems to be working pretty well, pretty much like a low-tech version of acid. Anyways, this was a little arrangement i made as a test, and i kinda like it so i thought i'd post it here for feedback and such. Feel free to use this loop for any project in any way, credit is not required.

Warning-bass! keep it low on preview! this is for testing low range frequencies in controlled environments, you've been kindly warned=d. 20hz to 190hz sine wave sweep. Length=13 secondsbpm=128bars=7. .

A patch with nonlinearcircuits jerkoff ("chaos circuit based on the jerk equation and its electronic implementation by jc sprott") in the center. I had a question that needed an answer. Is jerkoff a stable lfo when not using the input to disturb the rythm?my answer is. It can be relatively stable, but sometimes it is wobbling around. The recording is from a wobbly jerkoff. One output to osc cv in and another to a vcf vc in. The third output goes to a comparator. The comparator generates a trigger every time the cv is passing the threshold level.

Recorded on sony pcm-d50. The federal sirens are tested every first wednesday of the month.

Testing/documening my nonlinearcircuits timbre!. "this is basically a clone of the buchla timbre found in the easel. ". Sound:1. Sine wave not going throught wave folder2. Sine wave though wave folder3. Triangle though wave folder4. Square through wave folder5. Saw through wave folder. An lfo is modulating the bias. No, when going through the folder the there is never a sinus wave. . . Next time. . . Also it is a matter of calibration. I should check it out.

Doing a test of how this looks on this site. Triangle wave raising octaves in steps. Took 5 tries but got one that im happy with. If you notice at the end the color starts going backward when the frequency gets too high, instead of going towards red. (which is actually the opposite of the wave length ratios in the light spectrum).

Ff chaos test conditions:cv in from nlc jerkoff. Square wave in from lfo, 1hz. 3 vcos tuned to 130,8hz and one "strange sound". Cv in on vcos are attenuated, about 50%. Gate 1 and cv 1 to vco pan leftgate 2 and cv 2 to vco pan rightgate 3 to vco pan centertrigger to "strange sound" pan center. Sound 1 - cv min and rate minsound 2 - cv max and rate minsound 3 - cv min and rate maxsound 4 - cv max and rate maxsound 5 - cv at 50% and rate at 50%sound 6 - jerkoff to cv in on lfo. Vco 3 gets cv from jerkoff - chaos.

Generated in audacity, this sine tone has an elevated pitch with lowered gain to emulate a generic censorship tone you would hear on public television. The tone is suitable for use in any field, most notably in video games, films or animations. Whether it's comical, functional or both, this tone is a viable resource for censorship detail.
