Quick Question about the settings of SndWF, SndModWF and LightModWF.

[Jos Bos]

Hello There,

I saw in the KBS Editior the following sections: SndWF, SndModWF and LightModWF.
There are six different setting for those sections:

Sine, Square, Triangle, Saw up, Saw Down and P. Noise.

My question is where can I find more information about the function or effects of those six different settings?



The manual called Kbs-v2-description has the following information about the SndWF, SndModWF and LightModWF:

SndWF Sound waveform. (Available waveforms are Sine, Square, Triangle, Saw Up, Saw Down
and Pink Noise). The waveform setting affects character of the tone generated by the
MindPlace device


SndModWF Sound modulation waveform. (Available waveforms are Sine, Square, Triangle, Saw

Up, Saw Down and Pink Noise) The waveform setting defines shape of the sound
pulses generated by the MindPlace device


LgtModWF Light modulation waveform. (Available waveforms are Sine, Square, Triangle, Saw Up,Saw Down and Pink Noise). The waveform setting defines shape of the light pulses

generated by the MindPlace device.

That is the settings for what waveforms you would like to use. You can select the waveform for either the entrainment pulse, light pulse, or the pitch. The pitch waveform will affect how the tones sound, and is pretty much there for aesthetics, but you can get some really trippy sounds by fooling with the pitch waveform. The tones, and especially the lights require more consideration.

The sine waveform is a smooth transition from off to on and back off. It is relaxing, and very forgiving when it comes to producing a pleasant sound. They do not produce harmonics in the brain like other waveforms can. Binaural and monaural beats are sine waveforms.

Square Waveform.PNG
Square waveforms abruptly turn the sound or light on and off. This sudden shift causes a strong cortical imprint, and can spark harmonics in the brain, meaning if you are entraining at 10 Hz, you may also be increasing brainwaves at 20 Hz, and to a lesser extent, a sub-harmonic at 5 Hz. This effect can be minimized by smoothing (rounding the corners) of the wave. Be aware that digital anomalies in the form of clicking and popping can occur when using square waveforms when not smoothed. Square waveforms are useful for faster frequencies when harmonics are not an issue or may even be desired.

Triangle Waveform.PNG
Triangle waveform is like a pyramid. It is similar to a sine wave, but has a very short duty cycle (the time the pulse is on vs off). It is useful for faster frequencies, and produces a dazzling light flicker.

Rising Waveform.PNG
Rising Sawtooth is similar to a triangle, but is set at an angle so it looks like a saw. The sound or light rises first, then falls. Sawtooth waves can produce some trippy sounds and dazzling light show, but don't really have any advantages for entrainment purposes.

Downwaed Saw Waveform.PNG
Downward Sawtooth is the same, but starts full on and then lowers.

Noise Waveform.PNG
Noise waveform is freeform and random. Mostly used for aesthetics and mind art.
