Strobe
This generator produces a stroboscope that oscillates at the desired brain frequency and also displays colour gradients.
Stroboscopes have a strong effect on brainwave activity, as they stimulate the entire visual fields of the occipital lobe. Caution is therefore advised for conditions such as epilepsy or other forms of light sensitivity, as they may trigger a seizure.
The stroboscope generator has two modes:
- ScreenIn this mode, the screen is made to flicker. However, this only works without interference at frequencies below half the display’s refresh rate. For LCD screens, the limit is around 15 Hz.
The advantage, however, is that it’s free on a mobile and you can even easily make a pair of goggles yourself.
- Specialised glassesThere are specialised glasses available on the market which use inaudible audio signals to control built-in LEDs. Their performance is significantly higher, and the frequencies extend well beyond 50 Hz. However, they are rather expensive.
This generator supports coloured SpectraStrobe™, but it also works with single-colour AudioStrobe® glasses.
Graphics
Various curves can be defined for:
Brain frequency
This describes the curve of the strobe’s oscillation frequency. For LCD displays, this should be below approximately 15 Hz. If using the master that also has higher frequencies, you can set a limit in the props above which the strobe is muted.Hue
This determines the progression of the hues. All colours are available.Luminance
The brightness ranges from 0% (very dark, black) to 100% (very bright, white). For pure colours, it is 50% in the middle.Saturation
This ranges from 0% (no colour, just grey) to 100% (full colour, vivid).Left/Right
In the lower half (less than 0.5), both eyes are illuminated synchronously; in the upper half (greater than 0.5), they are illuminated alternately.List
List mode is more suitable for precise values.
Properties
Name
A name for the generator. The default is ‘strobe’.Balance
Stereo balance.Master
Switch between controlling the brainwave frequency via the Master or via a custom profile specific to this generator.Waveform
The strobe can be operated with various waveforms:- SineSmooth, natural progression.
- SquareAbrupt transition, producing more pronounced geometric patterns.
- TriangleA transition midway between sine and square wave.
- Rising sawtoothRises steadily, then falls abruptly.
- Sawtooth fallingRises abruptly, then falls steadily.
Screen or goggles
The strobe’s operating mode can be set here:- SpectraStrobe™ or AudioStrobe® goggles.
- The display flickers when playing in strobe mode.
