First of all, thank you for a most remarkable achievement. I have tried products in the past that purported to synchronize meditation-level brain waves — usually overlain by sappy new-age music composed by non-composers — and was invariably disappointed. However, I have been using your Equisync II and Equisync III recordings for a few weeks now and the results are truly astonishing and live up to the claims on your website.
Meditation enhancement: There are several companies that sell brainwave entrainment sessions specifically designed to enhance meditation. The sounds provide a stimuli to focus on during the meditation, and the brain waves naturally shift towards the frequency provided. Whether meditation is actually enhanced by brainwave entrainment is a subject of debate. However, advanced meditators commonly experience brainwave synchronization – which the right and left hemispheres display the same frequency brain waves.  While there are scientific benefits of meditation, it is unclear as to whether they are enhanced, hindered, or unaffected by adjunctive brainwave entrainment.
I have been using the Equisync CDs at least 24 minutes 5 days a week. It instantly relaxes me, helps get rid of headaches and even hiccups! I have a stressful job and it helps prevent anxiety; I have not had a chance to check my blood pressure but I feel calmer. I have used other products before but I like the Equisync CDs much better; it is deeper and more relaxing.
When the brain is stimulated with pulsed sounds (neuro-electrical activity via the nerves originating from the ears), the overall activity of the brain will respond to and align with these pulses. By selecting the desired rate, the brain — via the frequency following response (entrainment) — can be naturally induced towards the selected brainwave state.
Entrainment is a physics principle in which one rhythmic system falls in synchrony with another rhythmic system. If you’ve ever found yourself moving your body to the beat of your favorite song, then you’ve experienced entrainment in its most basic form. Besides music, this principle can be found all around you, probably more than you realize. Here are a few examples:
There are also ways of directing the entrainment pattern to further stimulate the brain in a desired way. Not all audios stay at the same frequency the whole time. Some will increase and decrease for a desired effect. Some will blend different beats at certain time to exercise the brain in a specific way. It is things like this that separate a good audio from a mediocre audio, and the difference between the two is undeniable when compared.

The frequencies embedded into each NeuralSync™ audio integrate three audible tones with a fourth subliminal pulse. This inclusion of both audible and subliminal entrainment engages brainwaves far more efficiently than single protocols such as standard meditation practices, binaural beats or isochronic tones. Because this waveform is also balanced, it compels both sides of the brain into hemispheric synchronization much more easily and effectively than other methods.
When you listen to binaural beats/tones, you are actually listening to two slightly different pitched frequencies. Each frequency goes to each of your ears independently. When this happens your brain responds by creating a third tone, making up the difference between the two frequencies. This shift in frequency then shifts your brain’s consciousness and changes your state.
No side effects have been reported from brain entrainment use.  Most producers of the technology warn against the use of brain entrainment by children under age 18, people with seizure disorders, and pregnant women.  Studies have not been conducted on these populations to date.  Additionally, (and this goes without saying) it is suggested that you do not drive while listening to brain entrainment due to the relaxing effect.
Until NeuralSync™, brainwave entrainment involved inferior linear, single or sequential protocols - such as binaural beats or isochronic tones - that were natively restricted in their ability to affect the natural complex dynamics of the brain. But now, NeuralSync™ significantly improves entrainment by incorporating EIGHT SEPARATE BUT SYNERGISTICALLY-INTERACTIVE DIMENSIONS into a dynamic and cohesive process powerful enough to compel the brain to produce whole-brain synchronization for intense effect. Incredibly superior to binaural beats or isochronic tones, NeuralSync offers an entrainment experience beyond anything you've used before.
In general, we are accustomed to being in the beta brain rhythm. We are in a Beta brainwave pattern when we are consciously alert. It is the default and dominant brainwave for most of us most of the time. We are in Beta when we feel agitated, tense, hurried, pressured, afraid and stressed. The frequencies range from 13 to 60 pulses per second in the Hertz scale.

Recent research at the University of Lisbon finally uncovered the reason for the 350 year-old mystery, finding that the resonance of sound is the mechanism for entrainment of swinging pendulums and ticking clocks, and it seems likely that the energy transferred by sound is also responsible for other observations of entrainment, including brainwave entrainment.
Thank you for the info. I must add that the Yoga Nidra state is the state in which a person can be in Delta but fully conscious. I did experience this state accidentally 3x in 2yrs after discovering Swami Rama’s teachings about the state&1 of the techniques for it(only 4 seems to exist & are practiced in monasteries at the time,according to him. He was the yogi who 1st demonstrated the 4 states,fully aware of himself & his surroundings, under lab conditions).
Use traditional meditation to create the changes in the brain that lead to the benefits I’ve described here. Of course that means going through a long learning curve while you master the art of meditation, motivating yourself to sit each day to meditate. And, to get the benefits I’ve described, you’ll need to meditate several hours each day), and continue in that way for 30+ years.
Good to hear from you and glad you got some value from the article. In total honesty I do feel that brainwave entrainment is safe, and that the big point is not to over-use it, or to push yourself too hard. You can almost think of it like an herb or nutritional supplement. You don’t expect big results the day/week of taking it, and if you don’t get results, you don’t keep taking more. You take it in regular safe doses over a recommended period of time and let it synergistically work its magic. Generally I think you are safe to listen to the audio you made, I just recommend taking it gradually with gamma in particular. Listen for just 10-15 minutes at first and see how your brain handles it. If it doesn’t produce any unwanted feelings then jump right in. But even then I recommend only listening once per day, and taking one day off per week.
Brainwave entrainment is clearly NOT an effective standalone treatment for mental illness, but it may be an effective adjunct treatment in certain individuals. It should also be mentioned that when using brainwave entrainment, you may want to have a specific purpose in mind. If your goal is to relax, yet you’re using a protocol that is stimulating, you may falsely conclude that it doesn’t work even though you’re using the wrong protocol.
While it may not be a perfect therapeutic option for treating certain psychological conditions, brainwave entrainment is yet another tool that warrants further testing and exploration. There is clear evidence that certain protocols may benefit human performance. Unfortunately nearly all of the research has been conducted by those who clearly are affiliated with those who manufacture brainwave entrainment products.
I have been listening to relaxing music on YouTube while writing (I write for a court TV show) YouTube recommended Binaural Beats; I thought the sound was annoying at first, and almost moved on from it, but when I felt a tickle in my brain (It sounds funny but I’m being honest!) I decided to research about Binaural Beats and came across this amazing, informative website, it’s only been a few minutes of listening to Binaural Beats and I’m hooked! thank you
Delta (3hz – 0.2hz) – Deep, dreamless sleep. Intuition. Empathy. Brainwave expert Judith Pennington calls it the doorway to Universal Consciousness and “A radar that scans the environment and psychically picks up information and energy.” According to British physicist C. Maxwell Cade “There have been reports that delta waves appear at the onset of paranormal phenomena.” (More information can be found in Cade’s book The Awakened Mind)
Entrainment is a term originally derived from complex systems theory, and denotes the way that two or more independent, autonomous oscillators with differing rhythms or frequencies, when situated in a context and at a proximity where they can interact for long enough, influence each other mutually, to a degree dependent on coupling force, such that they adjust until both oscillate with the same frequency. Examples include the mechanical entrainment or cyclic synchronization of two electric clothes dryers placed in close proximity, and the biological entrainment evident in the synchronized illumination of fireflies.[13]
