REQUIREMENTS:

Equipment:

• Computer, with a soundcard.
• Speakers (external speakers or headphones) connected to the computer.

Software:

• CoolEdit (now Audition)

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

Using C00L EDIT (brainwave synchronizer):

For more information regarding the ‘brainwave synchronizer’ feature of Cool Edit, you may refer to CE’s help files on the subject.

The following are the basic steps necessary to make a brainwave entrainment file with Cool Edit’s brainwave synchronizer.

1. Find a sound file that you find pleasing to listen to. Classical music will do but be aware that the output after the ‘brainwave synchronizer’ process will not sound as good as before. The sound file will become sort of choppy or wavy. One of the sound files I used in one of my experiments was one where there was a mixture of wailing of whales, sea waves, water trickling every now and then, some soft flute in the background, and other complimentary sounds. Make sure that the whole sound file has no silent portions within, and that the soundfile has more or less the same volume throughout. And since a brainwave entrainment file should be at least 15 to 20 minutes long, you need to process your file so that it is 15 to 20 minutes long too.
2. With Cool Edit open, Click on File > Open… and browse to your chosen file.
3. Select the whole file by double-clicking on the middle horizontal line on the wave display window.
4. Click on Effects menu > Special > Brainwave Synchronizer…
5. The resulting dialog box presents you with two (2) main settings you can tweak with – Low Settings and High Settings. If, say, you want your 20-minute file to ramp from 14 hz down to 7.83hZ, then back up to 15hZ, you would thus set the Frequency at 7.83 in the ‘Low Settings’ box, and 15hZ in the ‘High Settings’ box. (see illustration below)



6. For this example, just leave all the other settings at their default values. You may experiment later by adjusting these settings and checking how it fares with you.

You have just created a 20-minute brainwave entrainment file using Cool Edit’s ‘brainwave synchronizer’.

As with most things, some people find this type of file more entraining while some say the binaural type works best for them.

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’.
