In physics, entrainment is the process of two oscillating systems coming to assume the same periodic rhythm, such as is observed when two clocks slowly synchronize their ticking and tick together in harmony after some time. Pendulums also achieve this same synchronicity when swinging in close proximity to one another, a phenomenon first observed and written about in 1665 by Christiaan Huygens, a Dutch scientist.

Hi i’m just writing to let you all know that your Equisync CD’s are amazing! Just last night i was meditating to “Equisync II”. The one that has mostly theta binaural beats in it. I gotta tell you i have never had a meditation like i experienced with this CD. At certain points during the meditation it felt like my whole damn body was vibrating! That very night when i went to sleep I also had lucid dreams! It was so relaxing! I’ve tried “Equisync I” too, that one is amazing as well! I haven’t tried “Equisync III” yet. I can only imagine what that is going to be like!
No. The frequencies are consistent throughout the duration of each music production we offer. It could be argued that a better approach is to change the frequency over time, starting at a higher frequency when the listener is alert and slowly ramping down as the music progresses and the listener becomes more relaxed. So why have we not taken this approach?

I received my order on Mon. and have done 3 or 4 sessions of Equisync I. I just wanted to say I can already notice a difference in myself. I am much calmer and more clear thinking already in just 2 days. I don’t think it’s my mind playing tricks on me. Is this a common occurrence? Your product is great I can’t wait to try Equisync II and Equisync III.


Thanks Lorita. There hasn’t been any isochronic tones research that I’m aware of, for anti-aging, fat loss or attracting people, or any significant anecdotal feedback. You could combine positive affirmations or hypnosis scripts with isochronic tones to try and change habits and that could help with fat loss or build confidence to attract people. But it would be the affirmations and hypnosis doing most of the work, the isochronic tones would just be used to help relax the listener and put them in a more suggestible state. I don’t believe isochronic tones can affect those things, without being used in combination with some kind of vocal mental programming.
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.
·         THETA waves exist between 4 and 7 Hz. This is commonly referred to as the dream or “twilight” state. Theta is associated with learning, memory, REM sleep and dreaming. Memory development is enhanced while in this state. When in a theta brainwave state, memory is improved (especially long term memory), and access to unconscious material, reveries, free association, insights and creative ideas is increased.
Robert Monroe, a radio producer and executive published a popular book called Journeys Out of the Body about his out-of-body experiences when using brainwave entrainment. He later founded an original brainwave entrainment audio company, Hemi Sync. In 1981, the book Mega Brain by Michael Hutchison brought brainwave entrainment information, techniques, and terminology into the popular press.
They use a proprietary process of ‘3 point dynamic audio entrainment’ which means that they use both binaural beats and isochronic tones, layered together with another process called temporal entrainment (the stretching and compressing of sound waves in order to speed up or slow down the brain). This 3 pronged effect on your brainwaves is very powerful, so powerful they are currently in the process of trying to patent it.

-Frequency of the Tone Itself that Makes the Beat (Carrier Frequency): The first frequency was the rate of the beat pulsing on and off. This frequency is the sound frequency of the actual tone that comprises the beat. This frequency also has an effect on the way the technology affects your brain and consciousness. For example, too low of a carrier frequency for a binaural beat can be too much for a beginner’s brain to handle at first, and too high of a carrier frequency can be not enough for an experienced meditator’s brain to make big changes.
All brainwave frequencies are useful and beneficial at certain times – there is no brainwave that is intrinsically better than another. However, by deliberately choosing to attain a particular brainwave state, a corresponding mental state can be brought about at the same time. For example, a working person who has been in an overly alert beta brainwave pattern for many hours can quickly shift their mind and body into a relaxed state by listening to a few minutes of brainwave entrainment music for inducing alpha or theta brainwaves.

How brainwave entrainment works is quite simple. A tone or beat is overlayed into a track (usually with nature sounds or calming music) that pulses on and off at a specific rate. The frequency of that rate is matched by the brain, thus leading it to produce brainwaves that correspond with that particular frequency. The specific frequency range determines the brainwave produced (ie: alpha, theta, delta, gamma). For example, if the beat is pulsing on or off at a rate of 7hz, your brain will produce brainwaves at the frequency of 7hz, which are theta waves.
So you see, it’s all about where your personal journey is taking you, and what direction of evolution you are wanting to explore.  The purpose of this site is to assist you in making an educated decision about what product is right for you, and to ensure that you are only recommended a high-quality product that will provide you with powerful and noticeable results.  The great news is that many of the benefits of using Brainwave Entrainment (improved sleep patterns, release of anti-aging hormones, whole-brain functioning, etc.) are simply side-effects of using any type of brainwave entrainment audio.

Just as you turn the dial on a radio to get the station you want, with Brain Sync you can tune your consciousness to the ideal state of mind. Want to meditate or explore the mysteries of your mind? Listen to Theta Waves. Want to study for an exam, Gamma Waves will boost your brain into high gear. Need a good night's sleep? Delta Waves will help you get the rest your body craves. Feeling overwhelmed and need to chill? Alpha Waves wash away stress and increase creativity.


As somewhat of a modern mystic, I have studied altered states of consciousness, but due to my monkey mind, I have only been able to experience them to a very minor degree. I have tried so many methods of meditation to little avail. But I became aware that I would not be able to progress in my spiritual life if I could not achieve at least a modicum of success in meditation.
The formal name for this process is called the “frequency following response”, where the human brain will literally “follow” a specific frequency/beat after being exposed to it for (usually) about 8 minutes.  Technically the definitive term “entrainment” does not exactly match the actual process of what is happening to your brain when listening to these audios, but its close enough, and the name has stuck now with these products becoming more popular and widely known.
Beta is the most common brain wave pattern: Beta brainwaves are produced when we are wide awake, alert, active and engaged in mental activity, usually involving more the rational, reality-oriented left hemisphere of our brain. When beta wave activity becomes very intense, our brain hemispheres become less synchronised. Beta state is required to function properly in your everyday life.
Research: the authors stated that qualitative electroencephalogram signatures needed to be developed for different disorders and tested using standard validated methods of psychological assessment. Larger RCTs were needed with clear inclusion criteria for participants. The RCTs should measure qualitative EEG, hormone levels and the time of day of the intervention. Interventions protocols should be clearly defined and the relationship between session frequency/ duration and outcomes should be explored. More studies of auditory stimulation were needed, as well as studies comparing different types of stimulation, monaural, binaural and isochronic beats and use of white noise versus music.
Delta brainwaves have the slowest frequencies, ranging between 0.1 and 4 hertz, and these are the brainwave states associated with deep sleep, trance states, and unconsciousness. Few people can remain awake during delta brainwaves states, although this state is recorded in awake infants between ages of three months and one year and also in babies just before birth. Delta waves are also linked with increased production of HGH, DHEA, and the neuro-transmitter serotonin.
In 1839 Heinrich Wilhelm Dove discovered binaural beats, which led to the further discovery of the frequency following response and the beginnings of the science of brainwave entrainment. This science uses the power of specialized sound to FORCE your brain to stop producing defective brainwave patterns - OVERRIDING them to create positive neural feedback instead. Endorphins are created to alleviate pain, serotonin increases to combat anxiety - happy brain chemicals of all kinds are made in response. And the best news? As you continue with it, your brain re-learns to produce these healthy, beneficial and healing brainwaves on its own!
For centuries, brainwave entrainment has been associated with a number of benefits. Of the range of brainwave states that exist there are four frequencies that are the focus of brainwave entrainment; each of these states has a different physiological effect and achieves a different result. What they have in common is the power to trigger your state of mind in order to get a specific outcome.
A popular opinion in the brainwave entrainment community is that listening to isochronic tones without music produces a much stronger effect.  However, in the study by Doherty, Cormac. “A comparison of alpha brainwave entrainment, with and without musical accompaniment” (2014),  it was concluded that brainwave entrainment was equally effective for isochronic tones, both with and without music.
Hi Sahil, it’s hard for me to speak about other people’s tracks and videos, as I don’t know how they created them either. If you’re interested in a particular track/video and unsure about it, try asking the creator a question or two about the track, what frequencies were used and for how long, what software they used etc. Then make your own judgement based on how they reply to you.

Because the brain filters and interprets reality in a split-brained way, we tend to see things as separate and opposed, rather than as connected and part of the oneness spoken of by the great spiritual teachers (and, in the last few decades, by quantum mechanical physicists). Thus, at a deep level, the dual structure of our brain, in conjunction with brain lateralization, predisposes us to see and experience ourselves as separate from, and often in opposition to, the rest of the world—instead of experiencing the elegant interconnectedness between us and everything else. Our childhood associations and programming build on this inborn tendency by training us to seek this and avoid that, to move toward pleasure and away from pain, to do good and not bad, and so on. The greater the lateralization in the brain, the greater the feelings of separation—and the greater the feelings of separation, the greater the fear, stress, anxiety, and isolation.

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.
The Transparent Corp forum – This forum is an invaluable resource for any brainwave entrainment user or enthusiast.  Most of the feedback is obviously focused on the Transparent Corp software, but with over 20,000+ posts now you can find answers to the whole array of brainwave entrainment questions on there.  (UPDATE: Sadly, the Transparent Corp forum has now been taken offline)

Since most of us spend our days in the beta state, EquiSync excludes the beta brainwave frequencies, and entrains only those responsible for the most beneficial brainwave states: alpha, theta, and delta waves. The two charts on this page illustrate the basic benefits of each brainwave state as well as the basic targeting of the EquiSync programs 1, 2, & 3.

I appreciate your compliment on my article Henry. I’ve been using and reading up on isochronic tones and brainwave entrainment for many years, so it was just a case of trying to put a lot of what I’ve learnt into one article. I don’t have a great deal of knowledge or experience in using hypnosis and subliminals, so I’m afraid I wouldn’t be in a position to create something so extensive in reviewing them.


The authors concluded that preliminary evidence suggested that brainwave entrapment was an effective therapeutic tool, but further research was required. The evidence presented appeared to justify the recommendation for further research. In view of the lack of controlled evidence and problems with methodology and reporting in the review, the authors’ conclusions regarding efficacy did not appear reliable.
