REQUIREMENTS:

Equipment:

• Computer, with a soundcard.
• Speakers connected to the computer.

Software:

• CoolEdit (or Audition)

If you don’t have CoolEdit, you may use some other software that has the features offered by CoolEdit. The steps may be different. Improvise.

Isochronic Beats (Isochronic Entrainment)

The beats in ‘isochronic’ and ‘binaural’ methods are essentially the same, except for the following:

1. With isochronic beats, the brain doesn’t have to exert extra effort of interpreting the difference between 2 tones as with binaural tones (thus isochronic entrainment is better).
2. While binaural tones require stereo, isochronic tones don’t.
3. While binaural tones require the use of headphones/earphones, isochronic tones don’t, although headphones are still recommended.

If you’ve heard of the whoosh-whoosh of an old long-bladed ceiling fan, or any repetitive beats at regular time intervals for that matter, then you have basically exposed yourself to isochronic tones before and most probably have experienced isochronic entrainment.

Using C00L EDIT (isochronic beats for isochronic entrainment):

• With Cool Edit open, click File, then New, or just press Ctrl-N in the keyboard.
• Select 44100 sample rate in the New Waveform dialog box. Then click OK.
• We’re gonna use pink noise for our beat, so in the menu bar click ‘Generate’ > ‘Noise…’
• Choose ‘Pink’ in the Color box, and type 0.125 in the Duration text box. Click Ok.



For this example, we use 0.125 (1/8 = 0.125) seconds because we want to produce an 8 hertz beat.

• On the window of the resulting display, click approximately in the middle, hold and drag to the end in order to select half of the displayed wave.
• Then in the menu bar, click ‘Effects’ > ‘Silence’. Resulting wave in the display window should be more or less like this:

• Try out the file by pressing the ‘Play Looped’ button. You may make adjustments to make the sound more ear-friendly, e.g. fading in/out the edges, normalizing, lowering amplitude amplification, etc.
• Switch to Edit View. Insert the file into a track.
• Right click on the file in the track and select ‘Loop Duplicate…’ 128 times.
• From the menu, click ‘Edit’ > ‘Mix down to file’ > ‘All waves’.
• Clear the track, then insert the new ‘mixdown’ file, and ‘Loop duplicate…’ again. Repeat this process until you have a file with a total length of at least 20 minutes.

There, you have just created your first isochronic entrainment file.

REQUIREMENTS:

Equipment:

• Computer (not the ones you bought way back in 1997!), with a soundcard.
• Headphones connected to the computer.

Software: (any one of the following)

• CoolEdit (now called Audition)
• BWGen

There are other software related to the above-cited ones, like SoundForge, etc. You can use them if you have them in stead of any of the above.

Using C00L EDIT (binaural tones):

1. With Cool Edit open, click File, then New, or just press Ctrl-N in the keyboard.
2. Select 44100 sample rate in the New Waveform dialog box. Then click OK.
3. For this example, let us create a constant binaural tone of 10 hertz using 150 hertz on the left and 160 hertz on the right channel. So, now the right window is partitioned into 2 blocks, one upper and the other below it. Bring your cursor to the uppermost line in the upper block. A tooltip that says ‘L’ should appear right next to your cursor, meaning, this block is for the left channel. Click on this line. You’ll know if you did this right by observing 2 things: first, the green horizontal line in the center of the lower block has turned grey; second, only the upper block has a vertical yellow dotted line below its yellow arrow on the leftmost side of the block. Note that the colors I mentioned here may be different with yours if you have changed the default colors in the Settings.
4. From the menu bar, click Generate, then choose Tones.
5. On the Generate Tones dialog box, make sure that the ‘Lock to these settings only’ is checked. Type 150 in the Base Frequency box. The other textboxes below this should have 0, 0 and 1 respectively. On the bottom portion, there is a ‘General’ box which contains the ‘Flavor’ dropdown box. Choose Sine. Then enter 6 in the duration (seconds). Then, click OK. You have just generated a tone of 150 hertz for the left channel only.(Scroll down to see illustration below)



6. Now, it’s time to work on the right channel. Bring your cursor to the lower block’s lowermost line that outputs the letter ‘R’ tooltip. Click. Then, to make sure that your right channel tone starts at the very beginning, click on the button that has the symbol ‘|<’ on it. Or you can just press Ctrl-Alt-Home instead. Again, you’re doing ok if you see a yellow vertical line at the beginning of the lower block only., and the upper block is greyed out.
7. Like you did for the left channel, Click Generate, then choose Tones.
8. Change the 150 you entered earlier into 160. Click OK.
9. Check out what you’ve just done by clicking on the centermost horizontal line that divides the two channels to enable both channels. Then press the ‘Play Looped’ button (the one with the infinity symbol).

The file you’ve just created is a 6-second binaural tones file. If you want to make it into a full 30-minute file, it will just be a simple matter of inserting it into Multitrack View and then ‘Loop Duplicate’-ing it to the proper number of times, mixing it down and saving it as, say, ’10hz binaural.wav’ or ’10hz binaural.mp3.

These are basically how, most, if not all, brainwave entrainment products in the market are created. The difference is that those in the market are created professionally by professional people who have spent real time and effort in experiments to make the final output as perfect and effective as possible. They also may have invested in special and sophisticated equipment as well as human resources in the production of their products, not to mention special sophisticated software. With regard to techniques and data, ours are very basic while they may have data and technology that they naturally will not divulge to the public as it is considered their ‘trade secret’.
