Purpose: assists the listener in achieving the trance state. What is it: I've spent quite a bit of time studying the theory of binaural signals, and performing signal analysis of many commercial solutions (TMI products, HolosyncÆ, Awakened Minds, etc). I also analyzed those BWGEN presets that have many positive user comments, in attempt to extract common traits of what constitues a good binaural profile. This track is the result of all that research and several sleepless nights of hacking in Adobe Audition and BWGEN (creating background took 90% of the time). The background closely resembles that of Hemi-Sync, but there are few subtle differences, which make my version sound a bit less dry, and somewhat blizzard-like sounding. The relative amplitudes are such that the binaural signal is just on the hearing threshold. What's inside: For this track I decided to keep things general, which widens range of applications, which include, but not limited to: falling asleep, meditation, OBE, or any kind of trance-related work. In the future, I might make something specifically targeted for OBE. How to listen: You MUST use headphones, or speakers on the sides facing your ears, if you really have to. Using high-end equipment does not increase the effectiveness of the signals, so your average crappy cans will do the job. Comfortability is a plus. Set the volume to comfortable level - more on the quiet side. If you are in a noisy environment, use volume high enough to cover the outside noise. If you can easily distinguish the carrier, or if you feel that there is too much rumble in the lower end of the spectrum for your taste, you can use equalizer on your equipment to suppress lower frequencies, but don't kill it. The optimal volume is such that if you concentrate REALLY hard, you can barely distinguish wobbling (may appear erratic) in the lower end. If the wobble is very apparent and stable, you should decrease the bass. How it works: The binaural profile of this track closely resembles that of HolosyncÆ. In fact, there are only two major differences: 1 - it is free; 2 - you don't get a ton of follow-up motivational letters. The first Holosync track, The_Dive, lowers the frequency from the Alpha into the deep Delta state (2.5 Hz) using single carrier masked by the sound of rain and crystal bowls (which annoyed the hell out of me). The second track, Immersion, keeps the carrier in Delta, and the crystal bowls are now gone. This track does the same thing, except that it is combined into 1 60-minute session. CRI accertains that lowering carrier frequency increases the effectiveness of the signal. In their zillion-level gazzilion dollar program they lower the carrier frequency for each level. But the trick is - you need to pay hundreds of dollars for each subsequent level. I do not subscribe to the idea that lowering the carrier increases the effectiveness. However, I do think that low-frequency binaural signals are better suited to ride on low carriers, while higher-frequency signals - on higher carriers, which is a common theme with TMI - they use carrirers much lower, as well as much higher than CRI, depending on what we are trying to accomplish, so the CRI and AwakenedMind's statements that they use "lower carriers than anybody else" are not quite true. The carrier signal in the Abyss track is scheduled (from 160 to 80 Hz) to correspond current binaural frequency. The Level1 Hosolync uses constant 140Hz carrier, while Level2 rides on 112Hz. If they keep going in this fasion (factor of 0.8), this track is somewhere around Holosync Level4. The file is 192kbps Lame-encoded mp3, which should keep the balance between the file size and the quality. If you are a purist, contact me and I'll send you 320kbps .OGG version or something ;) If you use it, or compare it against other products, please post your experiences here. And remember: the binaural stimulation will not make things happen for you - the signal merely guides your brain to appropriate frequencies, but it is your job to follow them. To quote The Bob, "these excercises... do not create change in you. Only you can change you" (that was pulled from the memory, but I'm pretty sure thats what he said). Big thanks to Adrian for his cooperation. alt0xFF P.S. Do not listen to this track (or try to enter trance state, or meditate) while driving.
