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.
Dissociative but not present. In college I started having difficulty with reading comprehension/absorption (not dyslexia, I could read everything out loud easily but not gather the meaning). Over the past two years or so, my memory has been concerning, as I am not middle or late aged. Since it had been getting worse, I have been researching for several years now for a cure. Biofeedback led me to neurofeedback (which I can’t afford at the moment).
Years of scientific study combined with the personal testimony of thousands of people establish that using brainwave entrainment techniques positively affects the physical, mental, emotional, and spiritual well-being in a majority of users. You can easily take advantage of these powerful methods of personal self-help and self-improvement by downloading a variety of entrainment music right now.

Different people have different requirements when it comes to frequency changes in the music and it's quite impossible for us to anticipate them all. We would need to produce so many different variants of all our music productions that it would be impractical to manage and confusing for our customers. For example, if we were to start raising the frequency from theta up to alpha between the 50-60 minute mark of a piece of music, this would be useless to someone who used the music for a guided meditation that was only 45 minutes long. In the early stages of the development of our brainwave entrainment music we had so many different requests from different people that we could only opt for the simplest solution, which is to use a consistent frequency throughout. It might not be the absolute "perfect ideal", but this is still a very effective technique and the feedback we've received on our brainwave entrainment music has always been exceptionally positive.
Memory: There is not sufficient evidence to suggest that brainwave entrainment improves memory. However since cognitive function improves as a result of entrainment, short and/or long term memory may be improved by stimulation with certain frequencies. While lower frequencies may be beneficial for recalling certain memories, conscious processing of the memories generally requires sufficient beta.
To get a full answer you should really get in touch with the owner of the app, because it does really depend on how their track is constructed and how they intend it to work. I have one 50-minute sleep track which takes you down into delta (http://www.mindamend.com/shop/sleeping-and-dreaming/sleep-induction-isochronic-tones/) and that is designed to just get you to sleep, so you just let play until the end. If you played that track on repeat it might make you jump and wake you up, as the track begins at a higher frequency. I have another 8-hour sleep track which is meant to be played all throughout the night (http://www.mindamend.com/shop/sleeping-and-dreaming/deep-sleep-8-hour-sleep-cycle/). So it does depend on the individual track you are using.

With each pulsed tone, the brain produces an electrical response. The effects one experiences are the creations of the brains reaction to the “tones”, what neurologists call the “cortical evoked response” (the electrical response of the top most cortical layer of the brain). The brain is a mass of neurons, each taking part in storing, retrieving and transmitting electro-chemical impulses: information, colors, images, sounds, smells and tastes. Brainwave entrainment stimulates different areas of the brain allowing for the awakening and subsequent release of various levels of stored material. It also has an effect of  quietening the mind for clearer thought and process.
The objectives and inclusion criteria of the review were clear. Relevant sources were searched for studies, although the restriction to published studies in English meant that the review was prone to publication and language biases. The authors did not state whether steps were taken to minimise the risk of bias and error in the processes of study selection and data extraction (for example, by having more than one reviewer independently make decisions). The authors mentioned which studies were blinded, but it did not appear that study validity was systematically assessed, which made it difficult to judge the reliability of the review findings. The decision to combine studies by narrative synthesis appeared appropriate given the strong clinical heterogeneity between the studies, but the authors failed to quantify the size or statistical significance of the findings reported. The evidence presented appeared to justify the authors’ conclusions that further research was justified, but in view of the dearth of good-quality evidence and problems with methodology and reporting in the review, the conclusions regarding efficacy did not appear reliable.
I have personally used Holosync, Neuroprogrammer 3, and now I'm currently using Brain Evolution System. They are all great programs within their own rights. Holosync is very pricey and takes many years to complete (6-10 yrs) for their 12 level program and has a hefty price tag of $3195 dollars for the complete set and it uses outdated binaural technology. Neuroprogrammer 3 doesn't have a set time limit for completion as you set your own pace and use whatever sessions you choose to use and you can get the ultimate version for under $100, but this isn't a program that you would use daily in most cases. It does use better technology ( binaural & isochronic ) but it more suited for specialized cases and can be used in conjunction with Holosync or BrainEv. I have just started using BrainEv and I am about to be into the second week. BrainEv uses state of the art binaural and isochronic technology and brings you through your states at a much rapid rate whereas Holosync focuses mainly on certain brain wave patterns during its sessions which could get your mind stuck in certain states because the brain gets used to the specific states it's been entrained to. Also, BrainEv takes just 6 months to complete and you can feel it working immediately. Holosync did do it's job but BrainEv takes the cake on this one due to the short duration of time it takes to complete and uses more advanced entrainment techniques that doesnt leave your mind in a static state. So I would difinately suggest using BrainEv ( first month is free; $299 for all 6 sets ) in conjunction with Neuroprogrammer 3 for more specialized brain training.
They are a useful and effective tool that allow you a structured means in which to entrain your brain into a desired, new brainwave state using an intended set frequency range of the audio track. Frequency ranges for desired sleep, recovery and deep meditation states to different/higher frequency ranges for performance “flow-states” and high-level focus and calculation.
I have spending time in a floatation tank for the last 9months and just recently added the audio of crystal bowls into the tank. HOLY FLOAT! If you have experienced the bowls live then you know the physical experience that they produce; aside from the meditative side. Well, this effect is accentuated 10fold while in the tank. I have also started to float with binural entrainment audio and have seen a few effects.
I have had your Equisync CD’s for a little more than 2 years. Some recent stresses prompted me to start listening to them again. Wow……these cd’s are no joke. I have been playing them consistently for the past 2 weeks and they are a tremendous help. I have to ask about the Equisync III cds. Can this elicit a detox reaction? I played it in its entirety one night and the next morning I felt like I was having a healing crisis. I am not complaining 🙂 I believe these particular cds allows tremendous amounts of healing light to enter the body through the higher chakras.
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.
Our everyday, waking brain used for active intelligence operates at approximately 13 hertz, which is in the range of high alpha or low beta frequencies. People who have certain learning disabilities and problems with attention often have low levels of 13 hertz frequency brainwaves in crucial areas of the brain used for sequencing tasks and doing simple math calculations. This is one concrete example of how brainwaves are associated with thinking and behavior. Each identified brainwave frequency has a different effect on a person’s ability to think, act, and feel.
  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.
Alpha (12hz – 8hz) – Awake, but deeply relaxed. Simply closing your eyes will produce alpha brainwaves. This category is associated with daydreaming, visualization, imagination, light meditation. Brainwave expert Anna Wise called the alpha range the bridge between beta and theta. (More information can be found in Wise’ book The High-Performance Mind)
- Added the ability to create a playlist of your own iTunes library music and use it as background. The behavior of the app with iTunes music is used instead of, or combined with our included ambience, is slightly different so please review the help. Notably, unlike our included ambience which can be played at a volume below the device volume, iTunes audio can only be played at the device volume. So when in iTunes mode the Ambience volume slider disappears.
I want you to know that I only post reviews and recommendations for products that have been personally tested by myself.  I have been in this game for more than seven years, and know that there are a lot of products out there in varying degrees of quality.  I have set up this page with the goal of saving you both time and money in exploring this realm, so you can get straight into the game of bringing yourself to that next level in your own personal development.
What happens when you meditate using the Profound Meditation Program 3.0 is that instead of statically giving the nervous system the same level of juice every day, you consciously attune and intuitively adjust your nervous system and your energetic system’s unique stimulation recovery cycle. With PMP 3.0, you have a type of system with enough carrier frequency power and biofield amplitude to push your nervous system and your energetic system for a lifetime—and it is a system as dynamic as your growth and recovery cycles are. This system will enable you to push your spiritual development and growth much more quickly, recover much more quickly, and experience less overwhelm.
Binaural Beats or “binaural tones” are created by playing slightly different frequencies separately into each ear. The difference between the two frequencies stimulates a response in the brain which correlates with this frequency difference. For example, if we present a 100 Hz tone to the left ear and a 105 Hz tone to the right ear, a frequency of 5 Hz is stimulated. This is what is known as the “frequency following response”.
There are differences between high (over 18 hertz), mid (15 to 18 hertz), and low range beta states (12 to 15 hertz). Low beta states are more relaxed while still being focused, making this a good range for many daily work related tasks like balancing a checkbook, making a shopping list, or driving to a new place. However, people with attention deficit disorder lack the mental focus for doing these types of activities, and studies have found people with ADD are often low in this range of beta brainwaves.
Hi EJ, at the moment, there hasn’t been any research to give an indication of how long you should or shouldn’t listen for. Over time, I’ve seen people use my tracks for longer and longer. I started off providing 30-minute study tracks, but through demand, I extended them to 3-hours. I know from the many thousands of comments I’ve had on YouTube that a large number of people play those 3-hour tracks on repeat, or listen to different ones, one after the other throughout the day. I’ve also seen apps where you can play tracks like mine on continuous repeat. So it’s common for people to listen to them all day while they are studying.

Hi Ulka, thanks for your compliment on my article. Unfortunately, I haven’t come across any studies or much discussion about the problem with habituation and isochronic tones and how to overcome it. The consensus among experienced users is to regularly change the frequencies and music soundtracks you listen to. Adding music to the tones does change the waveform you are stimulated with, so that’s one of the main reasons why I provide different soundtracks for my isochronic tones sessions. I have released some tracks which use amplitude modulations in the music, instead of isochronic tones. It might be worth giving them a try if you haven’t already. I have them in a playlist on YouTube https://www.youtube.com/watch?v=Lj5tHl2cuWw&list=PLveg0IEcZWN6OIRZyLkv0BJADY7Q6xFCl.
Behavior problems: In two separate studies with a total of 57 children, it was found that brainwave entrainment was able to significantly improve behavior problems. One of these studies was conducted on children with ADHD and determined that they significantly improved not only in regards to attention deficits, but also in their behavior. Both parents and teachers reported statistically significant improvements in how the children behaved.

There is a certain point where the promised benefits of brainwave entrainment become more esoteric, and based on internal, subjective experience of oneself.  A few examples would be that listening to brainwave entrainment on a regular basis helps to increase one’s self-awareness, or that it increases mental “sharpness”, or helps to heal emotional trauma and increase your tolerance of stress and negative emotion. 


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.
