I will jump right to the point and then explain why.  The best source, by far, that I have found for downloading binaural beats mp3s is The Unexplainable Store.

Here is why:

First, their vastly superior quality.  As you have probably discovered, I too have downloaded binaural mp3 beats from various sources, some free.  However, the recordings tend to be low quality and corrupted.  Binaural beats from The Unexplainable Store are very high quality.  Guaranteed even, to induce altered state of consciousness.

At The Unexplainable Store, they create all their own binaural mp3 beats from scratch.

Second, the huge variety of laser targeted binaural tones, each created for specific brain wave entrainment.  For example, there are specific binaural mp3 recordings for meditation enhancement, astral projection, inducing sleep, for anxiety, creativity, confidence, energy lift, motivation, prosperity, stress release and so forth.  Each is designed to induce a specific brain wave pattern.

The fact is, that while brainwave frequencies are generally broken into four categories, Beta Waves, Alpha Waves, Theta Waves and Delta Waves, there are actually many sub-categories.  The binaural mp3 downloads from the Unexplainable Store are carefully targeted at specific sub-categories.

And when it comes to inducing altered states of consciousness, Jim McElwee is an absolute expert! You have got to try the laser targeted beats for Lucid Dreaming, Astral Projection and Theta Meditation. Guaranteed to work!

Third, they are very enjoyable to listen to.  After all, who wants to listen to plain sine waves?  These binaural mp3 beats are accompanied by pleasing music, water sounds, and so forth.

Fourth is the mp3 downloads are very reasonably priced.

I really recommend you check them out.  If nothing else, do sign up for their newsletter and get a free 10 minute general binaural mp3 download that is excellent in itself.  (Great newsletter too, by the way.)

I have had great success achieving altered states of consciousness with The Unexplainable Store and you will too.

The lower the brainwave frequency, the more calm and restful you are.

(The precise boundaries between ranges vary among definitions, and there is no universally accepted standard.)

So, it follows that if you can alter your brainwave frequency, you could alter your state of consciousness and induce things like relaxation, creativity and deep meditation by inducing the associated brainwave pattern. And, in fact, this has been demonstrated to actually be possible.

The coaxing of your brain into a specific brainwave frequency is called brainwave entrainment. And, it can easily be done with binaural beats.

Binaural Beats are created by delivering a sound wave of a certain frequency to one ear and the sound wave of a slightly different frequency to the other ear. These sound waves are combined in the brain and the result is the inducement of a frequency below the range of human hearing, like less than 10 Hz for Delta waves, well below the 20 Hz hearing threshold. The induced frequency is the difference between the two sound frequencies delivered to each ear.

Using disparate frequencies and combining them to create a low frequency is what binaural beats are all about. Studies have actually proven (since brain waves can be detected and recorded) that the binaural beat frequency will cause the brainwave frequency to change to match the one being induced. This is brainwave entrainment, the coaxing of the brainwaves to a certain frequency by use of binaural beats.

And, I am living proof that it totally works.

So, if you want to achieve Theta Meditation, for example, you would use a binaural beat in the 4 to 7 Hz range. If you wanted to want to relax and concentrate on something, you would use a binaurla beat in the Alpha wave range, around 8 Hz.

Skillfully constructed, you can laser target the binaural beats to create any range of alterted states of consciousness. And that is what Jim McElwee at the Unexplainable Store does so well.
