Hi All,
I've done a lot of research on the CDs, using Adobe Audition's analysis tools to determine exactly what the soundtracks were or were not made of, and using that same software to create my own personal variations.
I'll try and give the exact "recipe" for Holosync CDs.
First I'll state what I've found to be inside those tracks, and second I'll give my advice for making personal tracks.
What’s in a Holosync soundtrack ?
1) one sine wave in each ear. One is constant, the other varies in the dive tracks. In immersion tracks, they are both constant. (not present in the “floating” soundtracks);
2) Raindrops (not present in the “floating” soundtracks);
3) Glass Bells (only in Dive, not in the Immersion soundtracks);
4) A peak in frequency at 15500 Hz, where the “Autofonix Silent Affirmations” are “modulated” (this is not present in AP, only in AL 1 and upward;
5) Nothing else. Sorry folks, there’s no “secret something else” in the soundtracks, special technology or what, that would make it more effective than other BW soundtracks from other makers.
Hey ! If there’s no “secret technology”, what makes the Holosync CDs so much more effective ?
In my opinion :
1) the use of the Dive before going into the “deep” meditation : it kind of “heats up and stretches the brain in preparation of the “exercise” it’s going to take;
2) the raindrops. White or brown noise are known in BW literature for enhancing the effect of binaureal beats. But it’s a real pain to listen to ! The raindrop sound is a random sound that has the same effect of enhancing the binaureal beats, but with the added benefit of being relaxing to the ear, instead of irritating like the white or brown noise;
3) the “revolutionary” Virtual Audio recording technology. It does make the whole listening less a strain on the ear.
All in all, it’s just remarkably well engineered soundtracks that put no strain on the listener. Other BW soundtracks are clearly not as “polished”.
What are the Binaureal Beats ?
1) in Dive : panning from 10 to 2 Hz in the first 20 minutes, and staying constant at 2 Hz for the last 10 Minutes;
2) In Immersion : 2 Hz, for ½ an hour;
3) In Immersion 1.5 : unsurprisingly, 1.5 Hz, for ½ an hour;
4) In Immersion 0.5 : 0.5 Hz, for ½ an hour;
5) In Immersion 0.3 : 0.3 Hz, for ½ an hour;
6) In Quietude (bonus CD in AP) : 10 Hz, for ½ an hour.
7) In Oasis (bonus CD in AP) : 8 Hz, for ½ an hour.
Here is the list of carrier frequencies
In the Online Demo : 80Hz
In Awakening Prologue : 140 Hz
In the Quietude and Oasis CD : 80 Hz
In Awakening Level 1 : 120 Hz
In Awakening Level 2 : 100 Hz
I'm currently on AL 2, so I have no real idea what the frequencies for lower levels are. I might post them when I receive the subsequent levels, if anyone is interested. I tend to think that Purification 1 uses 80Hz as a carrier frequency, but it’s only a guess, based on answers I’ve received from the Centerpointe staff regarding the relative “potency” of the Oasis and Quietude soundtracks compared to those of the levels of the program…
How to create Homemade Sountracks that sound (almost) as good as Centerpointe ?
1) rip the Immersion soundtrack to a .wav file.
2) Do a low-pass filter at 15000 Hz to eliminate the “Silent Affirmations”, if you’re using a second-hand CD
3) Eliminate the BB sine waves by filtering out all frequencies in a segment of +to-15 Hz around the carrier frequency (140 for AP, 120 for AL1, 100 for AL2, …). You’ve created a “naked” raindrops soundtrack.
4) Select the Carrier frequency you want for a lower level. Create Dive and several Immersion BB tracks, and then mix that with the “naked” raindrops soundtrack. Correct setting for the volume of the sine waves should be at minus30dB.
5) Et voila!
You could also mix in some favorite music of yours, if you like.
Actually, I'm already an "inner circle" member, so all of the above is really useless information in my case (I only wanted to figure it all out for curiosity's sake) : my 1800$ are already spent, and I'll get all my CDs the day I ask for them without having to cash out anything more.
Although I think after analyzing the AP tracks I had enough technical knowledge to create reasonably effective tracks similar to the rest of the program, my reasons for deciding to buy the whole program were the following :
1) Centerpointe's soundtracks really sound better than what I created myself;
2) I can get their customer support as much as I need, and I do find it helpful at some crucial times;
3) Since they've made their program so effective (judging from the effect AP had on me) I tended to trust the way they organize the rest of the levels (how they devised the progression for the carrier frequencies for each level)
4) cashing out the full price for the whole program was a way to assure myself that I'd be committed to go through the whole program in its entirety. I know I often lose courage in the long run. Havy paid 1800$ would give myself a permanent reminder : "you've paid dear money for it, you'd better make the maximum use of it !".
5) Since I intended to do the whole program, it was cheaper that way !
Once again, a super-long post !
I hope it’s useful for everyone around…
Cheers to all.
