Isochronic Entrainment: How to Create Isochronic Brainwave Entrainment Files with CoolEdit

The first 2 articles (How to Create Brainwave Entrainment Files Using CoolEdit, How to Create Brainwave Entrainment Files Using CoolEdit’s Synchronizer) dealt with creating brainwave entrainment files using ‘binaural tones’ and cool edit’s ‘brainwave synchronizer’, respectively. Today, you learn how to create isochronic entrainment files with cooledit.

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.
  • generatenoise

    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:
  • (image)

  • 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.
