What is this?
A generator of sounds specially designed to affect the consciousness state of the listener, because the frequencies they encode are similar to those employed by the electric activity of the brain.
What kinds of sounds it does?
Of many kinds, that can be summarized as follows:
- Noises, from harsh to bubbly, able to cancel or mask fainter noises.
- Beats, which define a variety of rhythms.
- Clicks, which use microsecond delays between ears in order to sound into and around your head.
- Binaural beats, subtly different sounds for each ear generated in a way that produces low frequency beats between the brain hemispheres.
How do these sounds affect the brain?
It depends on the kind of sound, but Deepware Brainwaves is mainly oriented to the synchronization of brain waves into specific frequency ranges. These ranges are described in the table you can find some paragraphs below, and each one of them is related to a consciousness state.
You can also use this app to cancel external noises, create sound ambients and even for music composition.
Why is this app better than others?
Its modular architecture, that allows for an infinite number of combinations. The enormous tweaking possibilities of each module is also worthy. In addition, is the only application of its kind able to improvise music (using a programmable composer) avoiding the monotony of hums and beeps that you find in other software.
Do brain waves actually exist?
Yes, they do. They were discovered as early as 19th century, and they are actual electric waves present in brain neurons. Using techniques like Electroencephalography is possible to measure and record them.
It is also scientifically confirmed that different states of consciousness (sleep, wakefulness, alert, hypnosis…) are related to different ranges of brain waves frequencies.
How many kinds of brain waves are there?
There is not a scientific consensus about brain’s frequency ranges and their effects on consciousness. This table shows the frequency ranges used by Deepware Brainwaves and the most accepted claims about them and their influence on the mind.
|0||4||DeltaDeep sleep with no REM activity. These frequencies are normally absent during REM sleep phase.|
|4||7||ThetaRelaxed alert, drowsiness.|
|7||8||Theta-AlfaREM sleep, thoughts of movement in resting body.|
|8||12||AlphaRelax at rest with closed eyes, but without sleeping. Also linked to hypnosis and trance states. Sleep or body activity tend to decrease these waves. Also known as mu waves.|
|12||13||Alpha-BetaAwakeness limit. All beta ranges deal with body movement and mind activity.|
|13||16||Beta 1Awakeness, absent or minimal cognitive processes.|
|16||20||Beta 2Awakeness, simple cognitive processes.|
|20||25||Beta 3Awakeness, normal cognitive processes.|
|25||28||Beta-GammaAwakeness, intense cognitive processes, stress.|
|28||50||GammaHigh mental or visual concentration, altered states of consciousness and some forms of meditation. Some papers raise the range’s upper limit to 100Hz.|
Does this software actually works?
The basis of Deepware Brainwaves and similar applications lies on the partially verified claim which says that external sensory stimuli (light, sound) can affect the activity of brain waves.
The problem is that is not enough scientific evidence on the subject. Brain waves have been investigated from the 1930s thanks to the work of pioneers like William Grey Walter, but these investigations have been nearly always aimed to the study of brain functions and/or the detection of pathologies.
Some investigators, just some years ago, have begun to study the brain effects of certain sounds in healthy people. E.g. this scientific paper from 2007 timidly confirms the effectiveness of binaural sounds, but assessing the need for further, deeper investigation.
Almost every study and claim done on this matter has been done by artists (like Brion Gysin), psychonauts and people closer to the underground culture(s) than to the scientific establishment.
In any case, due to suggestion caused by placebo effect, or due to real effectiveness, many people say that these sounds work with them.
Why does this app need a good CPU?
Real-time sound synthesis is not a light task, and audio generation is the main weakness of the Android™ system. That is why we have optimized the app’s CPU consumption a lot. But its calculation requirements will still be great compared to “normal” apps.
Does this app drain my battery?
The high CPU consumption should have a negative impact on the battery’s drain speed. However, we have observed huge differences between devices.
We can only recommend you control the battery consumption the first times you use Deepware Brainwaves. In such a way, you may avoid unpleasant surprises.
In any case, this application is conceived to be used mainly indoor and at rest, so many users will not have problems to use it while plugged.
Why do factory presets have different CPU usages?
Not all module combinations use the same amount of CPU. As a rule, the Chord modules with many tracks use a lot of CPU, while Noise and Click modules use much less.
Which is the reference device for CPU consumption in factory presets?
A 2012 Nexus 7 tablet. At this writing (November, 2013) that device is a medium-powered device.
Which is the minimum recommended CPU?
This app is not suitable for devices less powered than a Samsung Galaxy S2.
In any case, the continuous advances in hardware work in favour of Deepware Brainwaves being more accessible day after day.
Why Deepware Brainwaves does not include pain-killing sounds as other apps do?
Because Cranfcom is a serious company that does not play with people’s pain, raising any false expectations. One thing is software that allows healthy people to experiment with their brains, and a miracle cure for sick people is quite another.
Deepware Brainwaves is NOT a medical device.
