Cluster

This generator produces sine waves that are specially processed to trigger brain waves.

There are two techniques available which can be combined and seamlessly transitioned between:

Binaural tonesUsing headphones, two sinusoidal oscillations with slightly different frequencies are fed into the left and right ears. Strangely enough, this is perceived as a beat, even though the tones are not physically connected: there is no air that is caused to vibrate jointly by both sound sources. The brain now tends to resonate with this internally generated beat.
Isochronic tonesHere, a single sine wave is simply modulated in volume to match the desired brain frequency, which also acts as a trigger. The advantage is that this also works with loudspeakers or in mono mode.

To make these tones sound more pleasant, overtones can be added. It is important, however, to calculate these for binaural tones in such a way that the difference in frequencies is maintained. The Neurotransformer does this automatically.

The time curves of the various changing properties of the cluster generator

Various curves can be defined for:

Volume

This describes the trend of the volume during a session.

Frequency

The trend of the fundamental frequency (carrier frequency) of the tone.

Properties

The specific settings of the cluster generator

name

A name for the generator. The default is ‘cluster’.

balance

Stereo balance.

master

Switch between controlling the brainwave frequency via the Master or via a custom progression specific to this generator.

Isochronic/binaural waveform

Option to transition smoothly between isochronic and binaural tones

overtones

This allows you to activate overtones using the plus button. The frequency control determines the pitch, whilst the volume control determines its proportion of the overall sound.

automatic adjustment

This controls the pitch based on brain frequency, allowing the progression to be tracked acoustically as well. At 50%, for example, the pitch is reduced by half from the highest to the lowest brain frequency.
