Isochronic tones are the most recent and advanced method for brainwave entrainment audios. With isochronic tones, the same intensity is used for all tones, but they pulsate on and off at different rates. The speed, pattern, and rates of these tones can be changed and altered throughout the recording, and the brain will follow them into desired states. The use of isochronic tones opens up the ability to lead the brain into highly specific states, at specific speeds and intensities. This has opened up the doorway to producing both dominant and subdominant waves(i.e. an alpha brainwave state with subdominant theta waves), and the ability to lead the brain through different waves, at specific speeds (i.e. holding the brain in an alpha state for 10 minutes, then dropping it through theta for 20, and holding it in delta for five before bringing it back into alpha at the end of the recording.) This allows thousands of different possibilities in training the brain, and also makes the process of listening to these types of audios more natural, and more powerful. 
Alpha brainwaves are resonating just below beta brainwaves at the frequency range of 8Hz to 12Hz on an EEG. Beta brainwaves are the normal, waking life, active, rational thinking and problem solving brainwaves that are dominant in most people throughout the day. Alpha brainwaves begin to show up when relaxation occurs. Often times the simple act of closing your eyes can product spurts of alpha waves. Taking a few deep breaths or consciously relaxing will do the same. When alpha waves become dominant, the body and mind are usually comfortably relaxed.
  It's like gaining a new level of clarity... understanding.... wisdom. When you're able to artistically and logically render solutions to problems... when you can objectively and subjectively evaluate opportunities and their innate qualities... when you can read people and empathetically understand them... you're given a foresight that others simply lack.
Many people experienced in using alpha brainwave entrainment report that the state of mind associated with alpha waves is a time when they feel most consciously connected to their subconscious mind. The intense experience of hypnagogic sleep, reported by some people as a feeling of being awake and asleep at the same time, is also associated with alpha brainwaves.
* We made the decision in this update to return Brain Wave to a Portrait-Only App. We know some people will miss the Landscape UI, but we did this to focus on the Brainwave Entrainment and Audio experience, and to prepare for new devices and screen sizes. Maintaining and testing portrait and landscape layouts for iOS 5-8, HD&SD, and 3 Aspect Ratios had become the single most time consuming part of our development and testing, and soon there will be even more. 90% of our dev and testing time was spent tilting iPads and iPhones of different sizes and different iOS versions, tweaking code that had nothing to do with brainwave entrainment--the reason I and others use this app everyday. Once the new Aspect Ratio devices come out and we have time to test with them, then maybe Landscape will make a comeback on the iPad.
Although most experts will tell you that people can get through the day without the production of Alpha brainwaves, that doesn’t mean there won’t be any repercussions. For people who have suppressed production of these brainwaves, they can end up developing anxiety disorders and other stress-related diseases, which can lead to the weakening of their immune system.
It has been both a pleasure and an enlightening experience listening to the Equisync II CDs for the past month. As a 15 year stroke survivor, daily meditation has become a part of my life. Listening to these CDs reminds me of sitting alone in a forest during periods of rain, whether they be light, heavy, or in between. I am able to access my right hemisphere more readily and experience the feeling of nirvana that we all have within us. When I reach this point, my system reminds itself of all the compassion and connectedness we each have.
Participating in this program requires that you use your Holosync® soundtracks (!)—which takes some time. Though you’re free to do less (and progress more slowly), we suggest that you start with a half hour of listening each day, progressing to an hour a day. My bet is you’ll eagerly look forward to these sessions, though, rather than seeing them as a chore.

Besides, Holosync® users look forward to their listening session because the experience is wonderful, and you feel so good afterwards. But still, you do have to be willing to actually use the program. If you aren’t willing—if you don’t think the incredible mental, emotional, and spiritual benefits of this program are worth the time commitment—this isn’t for you.
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.
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.

When you embark on this accelerated journey, more than ever you need to understand that brainwave entrainment is a powerful tool, but that your actions, thoughts, and how you use this powerful tool are still strong determining factors in how much you get out of the technology. It’s not just an easy way out. You are going to have to go through a growth and transformational process.
Not only do certain brain wave rhythms get strengthened as a result of entrainment, but a dominant frequency band results in a different state of awareness. Those that have used a quality brainwave entrainment product can vouch for the fact that their perception is altered by their brain waves. Not only could this be due to brainwave changes, but it may be a result of increased interhemispheric communication.
Lucid dreaming: A lucid dream is considered a dream that a person is aware of and often able to consciously manipulate.  Many have alleged that using brainwave entrainment technology makes it easier to experience a lucid dream.  Scientists have studied this phenomenon and noticed that beta frequencies within the range of 13 to 19 Hz tend to be generated to keep the person conscious.  Additionally there is significant increased activity in the parietal lobes of the brain, which allows an individual to stay conscious.

Kelly Howell brings 30 year's experience to her expertise. She has been cited by the Mayo Clinic as "renown for her pioneering work in healing and mind expansion (and) visionary recording techniques." She has collaborated with neuroscientists and biofeedback therapists to invent a sophisticated sound recording technique that makes Brain Sync programs more effective. The result is the most elegant and effective brainwave synchronization audio programs available in the world today. You'll feel the effects from the very first time you listen. With regular use, you'll establish new healthy patterns that last. Brain Sync programs use window frequencies – extremely precise frequencies that fit through narrow biological windows to impact the body at the cellular level. The choice of frequencies selected for each program is based on biofeedback research. Programs are designed to help you self-generate optimized brain states exhibited by remarkable men and women.
You’ll learn about the science behind Holosync®, how it works, what happened as over 2.2 million others used it, and much more. This book means so much to Holosync® users that many bring it to public events so I can autograph it for them. Embarrassing for me, but also a compliment—and evidence of how much Thresholds of the Mind means to those who’ve read it.
NeuralSync™ is the ONLY technology that utilizes FOUR SEPARATE yet synergistically-interactive frequencies precisely calculated to induce each mental state offered in our catalog. Our exclusive 4-W.T.S.P.™ technology creates waves in a balanced 4-dimensional pyramid that are collectively complementary and interactive. Unlike other related programs that use only a single binaural beat or isochronic tone frequency (or several in sequence), NeuralSync™ applies all four simultaneously to immerse your brain into targeted and harmonizing perspectives.
Theta waves have another interesting characteristic. The Earth has a measurable resonance of 7.83 hertz known as the Schumann resonance. Because the Schumann resonance is a constant background frequency surrounding all life, it may play a special role in biological activity. The Schumann resonance frequency falls within the range of theta brainwaves and may have something to do with why these brainwave frequencies are so powerful. 
Brainwave entrainment also happens with the use of pulsating light, and visual and auditory stimuli are sometimes combined for additional effect and visual stimuli is used alone. Using brainwave entrainment techniques is safe for almost everyone, the exception being pregnant women and people who have seizure disorders who should check with their physician before using these methods.
How does brainwave entrainment work? Consistent, precisely engineered audio frequencies in the form of binaural beats cause the brain’s frequencies to match the stimulus. Your brain perceives two beats with slightly different frequencies (which are inaudible to the ear) through your headphones. It takes the difference between the two, and matches its own frequency to it. This is called the “frequency following” response.
