    Binaurals for Macs?

    I guess this is a series of questions...

    1) Does anyone know of a good binaural brainwave generator for Macintosh?

    2) Is there a chart in the form of a PDF file or jpg document that would serve as a quick reference to the properties of different frequencies?

    3) What is the best way to listen to binaurals? Does the quality of one's headphones or audio equipment make any noticeable difference?



    As an extra question, I've got Reason 4 on my computer, a program used to make music. It's a virtual studio that has synthesizers with just about every wave form you could possibly want. All the knobs, dials, and sliders can be automated so you can play with the sound and change it at whatever rate you want. Do you think I could use this program to produce my own binaurals? I think the only problem I would have is measuring the wavelength. I know that the A below Middle C (for the musicians out there) vibrates at 440 Hz. Is it worth experimenting with?

    Re: Binaurals for Macs?

    I can only really answer one of your questions, specifically about headphones.

    Yes, it does matter the quality of headphone you use. The higher quality, the stronger the effect due to clarity of signal. But be careful if you're purchasing higher-end headphones; some of them have noise-canceling or other sound-altering features that can alter the effectiveness of the binaural beats. I highly suggest that if you invest in expensive headphones that you go for studio headphones. They're designed to be as accurate as possible to the original signal. I recently got a pair of Sennheiser studio headphones for $90 that are amazing - I've used them both in the studio and for HemiSync. Although HemiSync doesn't work very well on me, I got more noticeable results when using the Sennheisers than when using my BOSE Around-Ear headphones, which cost $150 (but are great for listening to music with.)

    Re: Binaurals for Macs?

    I don't know about binaurals for macs, but there is a program that can be used for macs that 'translate' the BWGen or any other windows program in a mac. I believe it's stickied somewhere in the MAP section. I'll take a look and come back with a link if I have time.

    Ok, the link isn't helpful because the program isn't the same anymore. However I found an article about it with a link to a free download. Here it is:

    I hope this is helpful to someone.

    A binaural requires the ability to have two different tones, and that is all it is. The lower tone is the carrier frequency and the difference between the tones is the beat frequency. It is assumed that you will start with a beat frequency around 12 to 14 Hz so that when you close your eyes and sit quietly to listen you will start out with the beat frequency being fairly close to your initial starting point. Then it is assumed that you will choose to smoothly ramp from that starting frequency to your target frequency. Some people instead choose to have only the target frequency with no ramping at all; it just consists of the two frequencies by themselves with no change. Other people choose to use steps rather than smooth ramping. You might have a minute at 14 Hz followed by 2 minutes at 13 Hz followed by 2 minutes at 11 Hz followed by 2 minutes at 9 Hz and then drop to 7 Hz for the rest of the time as an example of a theta binaural. Using steps would be easier than ramping if you have the option of generating tones with your software but not the option to generate a tone that will shift over time to a higher or lower tone. Another thing that seems to be assumed is that your carrier frequency must be the same; this is not so. If you wanted to change your carrier frequency every minute it may be tedious to create but it would keep things more interesting for your brain. I find that my limit is about 80 minutes - beyond that I will come out of it even if the binaural continues.

    I have a MAC and have been using Sbagen to record .wav files for my iPod: http://uazu.net/sbagen/#dl_mac
    Some other programs that work on a MAC are:
    Gnaural: http://gnaural.sourceforge.net/download/
    Audacity (with the bitone plugin):
    (download 1.26a as 1.25 doesn't seem to work with bitone2): http://audacity.sourceforge.net/download/mac
    http://audacity.sourceforge.net/nyquist/bitone2.ny

    Here are some things I posted elsewhere regarding sbagen scripts that have helped me have OBEs:

    Last night after not having a lucid dream or an OBE for a long time (and only having had 2 real LDs and 2 real OBEs since October, 2007 -- and none of them facilitated by binaurals but rather by the Taoist Microcosmic Orbit and Zen Koan work) I went to sleep playing a Focus 27 I'd mixed, inadvertently followed on my iPod by two Theta slides, the first with a river sound, and the second without. During the first 1.5 hours, I had a lucid dream, and then after waking up and starting the Focus 27 one again, I had a full-blown OBE, exiting through the 3rd eye chakra. Until last night, I'd experimented with A LOT of pre-packaged binaural OBE packages by all of the experts without success (not to knock them -- they may work for others and even for me in the future, and may even have primed me for my recent OBEs -- I have the utmost respect for Hemi-Sync and the works of Bruce, Buhlman and Stack -- not sure, actually, if Buhlman and Stack used binaurals) but now I'm a believer, thanks to sbagen and a little bit of luck. Here are the 3 scripts, set to save in .wav format and then in .mp3 format. When the free downloads board opens, I'll post them there:

    sbagen -r 8000 -Wo TheParkFocus27.wav -L 0:30 -m river2.ogg -i 50+0.8/5 400+4/1 503+4.2/1 600+4/1 750+4/1 900+4/1
    sbagen -r 8000 -Wo ThetaSlide800to2.wav -m river2.ogg -p slide 800+4.5/1
    sbagen -r 8000 -Wo ThetaSlide800to2NP.wav -p slide 800+4.5/1

    sbagen -r 8000 -Wo TheParkFocus27.mp3 -L 0:30 -m river2.ogg -i 50+0.8/5 400+4/1 503+4.2/1 600+4/1 750+4/1 900+4/1
    sbagen -r 8000 -Wo ThetaSlide800to2.mp3 -m river2.ogg -p slide 800+4.5/1
    sbagen -r 8000 -Wo ThetaSlide800to2NP.mp3 -p slide 800+4.5/1

    Bon Voyage!

    P.S. If anyone is interested, I wrote a science fiction novella based on some LD and OBE experiences: http://unityspulse.ning.com

    Last night had another OBE listening to the same scripts, with the addition of a mix of Delta 1.5 and Beta 16 (I'll post them later). The whole sequence was 2 hours long and I listened once going to sleep, again during the night, and again in the morning between 5:45 and 7:20 A.M., and this last period was the one during which the OBE occurred, either directly from the conscious state during the Focus 27 mix, or upon the beginning of the Delta/Beta mix -- those would be my hypotheses. The OBE was preceded by "clairaudience" of a family member living on another continent making a phone call (but unverified), a new experience for me. I believe I helped the OBE along by using visualization of flying, at which point I felt I could emerge from the 3rd Eye but then felt my legs being pulled up and found my self flying backwards, without sight. I said in my head, loudly "Eyes Open!" and gradually I was able to see that I was flying backward (being pulled backward) over a river -- It should be noted that the prior OBE involved flying over rivers and mountains. I don't know if this is a region of the "The Park" in Focus 27 -- this would have to be checked out with other "frequent flyers." More later . . .

    [Mod Note: Links checked and approved. Normally, the "minimum post" rule would be in effect, but the links are excellent and there's no point being arbitrary. ]

    Thanks Mod -- Sorry I didn't check out the rules -- I'll read them before posting in the future
