More Details About Our Harmonic Layering Process

This information is provided for visitors who are interested in very in-depth details regarding our harmonic layering process. Because of the high level of complexity involved in the technology, we recommend that visitors read the rest of our Brainwave Technology section to familiarize themselves with how binaural audio technology works before approaching the technical details contained in this section.

The difference between our harmonic layering process and the "harmonic matrix" or "harmonically layered frequencies" used by other companies:

When most companies refer to a "harmonic matrix" or use the words "multi layering" or "harmonically layered frequencies", they are referring to a very simple and unsophisticated method of layering binaural frequencies. That type of method is quite easy to reproduce and is not at all like the complex and sophisticated harmonic layering process used in our audio technology, which is why it is important to us to make the distinction.

Don't be fooled by imitations. Most of the methods used by other companies are not even truly harmonic. They simply use the word because they think it sounds catchy. Our CDs are the only products using true harmonic layering.

How the "harmonic matrix" used by other companies is produced:

In the type of harmonic matrix used by other companies, there are typically any number of "layers" or pairs of frequencies. Rather than a single pair of frequencies used to trigger a binaural beat, they use multiple pairs of frequencies. For example, one of their soundtracks might contain one pair of frequencies at 200Hz and 205Hz (to trigger a 5Hz binaural beat), another pair at 230Hz and 235Hz (for the same 5Hz binaural beat), another pair at 270Hz and 275Hz (again, for the same 5Hz binaural beat), and so forth, all playing simultaneously within the same track. Occasionally, a company will also vary the amplitude of one pair of frequencies to make it stronger than the others. That process of using various pairs of frequencies is what most other companies refer to as a "harmonic matrix" or "harmonically layered frequencies".

There is, of course, nothing musically harmonic about their process at all and the word "harmonic" is simply used — or misused, in that case — because multiple layers of frequencies are being used.

How the Immrama Institute's harmonic layering process works:

Our harmonic layering process is, by its very nature, much more complex. Our technology involves multiple layers of frequencies blended together in a very precise and specific manner. Our process does not involve selecting a few random pairs of frequencies and layering them as in the example above, and also does not involve using a few pairs of frequencies and making one pair stronger than the rest. In our harmonic layering process, the frequencies are arranged very precisely, subtly shifting throughout the entire course of each track to maintain specific harmonic combinations as the track progresses.

Our harmonic layering process has its foundation in the principles of music science. Each frequency corresponds to specific musical "notes". Frequencies may be blended together in a harmonic manner in the same way musical notes may be blended together to create a harmonically pleasing composition. Just like some musical notes blend harmoniously with each other while others clash with each other and produce an unpleasant sound, frequencies may also be combined with each other to result in harmonious combinations. At every fraction of every second throughout the audio on our CDs, the frequencies are precisely engineered to be harmonic according to the truest sense of the word.

Even though the binaural frequencies are placed beneath the sounds of natural rain, and are embedded at a very low audible level and therefore not heard out loud in the same manner music would be heard, the brain still responds more effectively to binaural frequencies that are blended together in a harmonically pleasing way that is soothing to the ear and mind. This enhances the effectiveness of the audio technology, allows your brain to resonate smoothly and comfortably with the binaural beat, improves the process of whole brain synchronization, and enhances the overall experience by actively engaging many areas of the brain rather than a select few areas.

In our harmonically layered audio, the frequencies are not only selected based on the binaural beat they will trigger when combined with each other. They are also selected based on their harmonic relation to every other frequency being used in the audio at that particular moment. Finding the appropriate combinations of frequencies — combinations that would allow the frequencies to not only create the desired binaural beat but also simultaneously maintain the proper harmonic ratios — was an extremely complicated process that took us quite a bit of experimentation and a considerable amount of time to develop.

Why is the process so sophisticated and complex? Adjusting just one frequency out of the entire group of frequencies essentially requires adjusting every other frequency as well in order to maintain the proper harmonic ratios. Since the frequencies must be constantly adjusted from moment to moment to trigger the desired binaural beat — which changes over time during each track in order to guide the brain into the proper state — when one frequency is changed, every other frequency must also be changed along with it, with each frequency shifting up or down in tiny increments to remain harmonic. At the same time, each layer of frequencies must be oriented toward the appropriate brainwave state, which creates a delicate balance that must be maintained in order to preserve both the harmonic aspect and the brainwave aspect. Every moment of audio on our CDs was created using this method.

In addition, because our audio incorporates multiple layers of frequencies to stimulate the brain on multiple levels, each group of frequencies in each layer must be evaluated in order to ensure it does not conflict harmonically with any other group of frequencies in its own layer or in any other layer. All the groups and layers of frequencies shift in amplitude as well, fluctuating up and down at various points throughout the track, but never during the course of any track of audio is one group of frequencies selectively higher than all the rest. There are always multiple layers of frequencies at any given amplitude, in order to stimulate the brain on multiple levels simultaneously.

Our harmonic layering process is something we have never seen in any other binaural product, and we have thoroughly studied every other binaural product we have encountered. We consider our technology a truly unique and innovative approach to binaural audio technology, and its level of efffectiveness in listeners has definitely proven its value.
