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.

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.

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.

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.

Warning! loud noise! this sound is not intended to listen to, but to do technical measurements!. This is a test recording i made to measure my headphone's frequency response. It plays a nice "left" and "right" to determine the channels. Then it plays back white noise first in both channels, then one at a time. Then the same with sine sweeps. Then short impulses.

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.

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.

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.
