Another sloth lfo test. I wanted to see - expected to see - cyclesrepeating. I don't. I have x controlling frequency and y controllinga filter. This recording is 5 minutes so there should be some repetitiveness. . . It's a regular sloth. . . I see 48 second cycles but they are not the same. Cool. Chaos.

Full siren test (with a couple of gaps) including the announcement for each siren and two separate sirens. There's a perfect delay as the sound bounces around the city creating an almost digital sounding delay effect for the announcement and reverb for the sirens.

Test alarm of eschelbronn siren with church bells in the background. 7th of july 2018, 12 a. M.

Testing out the werkstatt-01. Slightly eq'd on the low end.

Recording of noise produced by unplugged microphone jack on my computer. Weird whistle sound moving from 6. 5 khz to 15 khz randomly with pink noise on background. Removed dc part of the sound and normalised with audacity. Sound was cut to make it loopable. Feel free to use it in short movies, games, etc. Just include a comment below and give me credit if used in game (i do not take a care on movies). . .

This is the alarm from sesc pompéia in sao paolo. They play it so loud that everyone has to get out of the building.

This sound is a 1-sample long impulse at 48 khz. It covers the whole frequency range with equal power. This is a perfect sample for exciting your guitar amp or reverb unit to capture it's impulse response (ir). You can also play it through a speaker in a reverbant room to capture it's reverb characteristics. Remember that the ir sample will be no flatter than your speaker's performance multiplied by your microphone's performance (frequency response characteristics). The sample has exaclty 1 second of silence, then the impulse, then another second of silence to ensure the impulse will be played clean and untruncated on any sound system or device. My test with ir lv2 convolution plugin have proven, that this sample has absolutely flat frequency response - convolved signal was identical to the source signal. After normalization and sample-alignment of the sound clips i have inverted the polarisatin of one of them and summed them - result was absolute silence, even no hiss was present as a result. This shows the accuracy of the convolution process and proves this sound to be perfect for sampling ir. The impusle was generated with c* dirac ladspa plugin. Created using audacity.

On the first wednesday in may the danish air alarm system is testet at 12:00. This was recorded in 2012, a beautiful sunny spring day.

I made this sound with a simple music maker, its (or gonna be) used in 8-bit game when the general tells the soldier what to do, please leave a comment what you think and what could be added, i'll try to add what you asked.

Yep this is a crazy sound. What have i done. . . I have build a nonlinearcircuits sloth lfo. Https://www. Modulargrid. Net/e/nonlinearcircuits-sloth-4hpedited info:i have built the regular version. The sloth has two outputs x and y. I connected x to control frequency on one oscillator and y to control amplitude on another oscillator. Frequency experiment on left channel. Amplitude experiment on the right. The file starts as the amplitude is 0. Next time the amplitude is 0 (almost) is at about 48 sec. Then 48 sec later, at 1:37 the amplitude is 0 again. The two cycles are not identical. The tones are harder to analyze. . . X and y outputs. I guess those corresponds to x and y in a coordinate system. You can find video clips watching the sloth “drawing” butterfly wings. For example:https://www. Youtube. Com/watch?v=0ku6npz1s4gand maybe check this:https://www. Youtube. Com/watch?v=occhcm5oxp8http://nonlinearcircuits. Blogspot. Se/2014/09/sloth-chaos. Htmlthis later link is the developers page. The constructor (andrew) of this module says that my version completes “1 cycle every 15 seconds”. What does that mean? is one cycle one lap in the butterfly pattern? will the pattern repeat itself? yep, i’m going to ask him…. Edit:andrew answers my questions: “it is a very approximate description of the frequency, cycle is not the proper term to use. . . . Nor is frequency really, but they are descriptions that people can relate to easily. Depending upon the pot settings and whatever other initial conditions that happen to be in place, the signal may traverse the typical double strange attractor path. It may stay in one attractor for several loops before crossing over to the other one. The pattern will never repeats itself, it might come close but won't do it. ”my question: so, one “loop” is one cycle?andrew answers: typically it takes approx 15 seconds to make a rough figure 8, but depending upon the pot and other factors, it may take longer, much longer, sometimes it even pauses whilst deciding which way to go next.

Everything that lives is designed to end. We are perpetually trapped in a never-ending spiral of life and death. Is this a curse? or some kind of punishment? i often think about the god who blessed us with this cryptic puzzle. . . And wonder if we'll ever get the chance to kill him.

A happy siren for a bad war. I made it in beepbox. Co.

Outdoor warning siren system, siren test on a sunny day. Birds can be heard chirping in the background while the siren is sounding.

Bass warning!a 13second sinewave, the tone sweeps up from exactly 20hz to 190 hz then stops. It was recorded in logic pro & i use it from time to time to do sub sweeps. If your speakers are loud please don't have them cranked up without hearing low first.

I'm testing a new module. . .

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.

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%.

Vco 3 gets cv from jerkoff - chaos.

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.

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).

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.

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.
