Free Sample Alpha Wave Tone

For those who have not tried the project on creating isochronic tones or those who are not technical enough to follow through with it but would like to get a feel of what these tones sound like and how it benefits the mind and body, I have prepared a sample alpha wave tone below. This sample together with tones for beta waves, theta waves and delta waves are available for listening free at the website: free brainwave entrainment tones which I built recently.

I'm making this available for everybody to try. There are people who can afford commercial isochronic tone products but are skeptical as to its effectivity and there are people who would want to buy but still hasn't got the budget for it. Here's now a chance for everybody to try it first hand. It really works that's why I want to share it with you.


This tone brings you to the alpha state just below the beta state. Entrainment should be easier since it's just below your waking state. For faster loading, the file is only one minute in length but is repeated 15 times to give an effective 15 minute entrainment.

The alpha wave entrainment is good for calming your mind, relaxation and stress relief. You will know if the entrainment to your brain was successful because you will feel energized after the session. Just try to focus on the tones so as to subdue the annoying and energy draining worries that you may have. Others have entrained successfully at the first session but others may succeed only after the second or third session.

Before entraining your brain to the lower frequencies of theta and delta, it's best to get used to the alpha state first. This state can bring so many benefits for both your mind and body while still being a little conscious and alert. After trying this, you may want to visit http://brainwaveentrainment.wealthnus.info/ for the lower brainwaves.

Check on this blog often as I'll post more articles on tapping the power of isochronic tones to bring you more health, wealth, abundance, success and prosperity.

How to Listen to Isochronic Tones

How to Listen to Isochronic Tones

Aside from a faster achievement of brainwave entrainment, listening to isochronic tones does not require the use of headphones unlike the more popular binaural beats. You can play it to your desktop speakers or speakers from your home entertainment system. This type of listening though has its disadvantages since external noise can compete with your isochronic tones; engine roar of a passing automobile,  the sound of power tools nearby, etc. These external noises can get you unfocused and may hinder the brainwave entrainment session.

Even though it is not a requirement, I prefer to use headphones so that I get my full attention in listening to isochronic tones thereby accelerating the speed of reaching the entrainment frequency.

How loud should it be?

A good guideline is to set your player to the highest volume that your ear is comfortable with. There should not be any discomfort or pain in your ear while listening to isochronic tones. This should minimize the distraction from external noises. You can achieve entrainment even with low volumes since the beats of these tones are very distinct unlike binaural beats and higher volumes can achieve faster entrainments. Just remember that comfort to your ears is of utmost importance.

Is it important to close your eyes?

Yes it's better to close your eyes when you are entraining at alpha and below so as to eliminate visual stimuli.

Watching a repetitive video can also bring you a faster entrainment such as this alpha brainwave entrainment isochronic tones video.

You can close your eyes if they become heavy and let the isochronic tones take care of the rest of your brainwave entrainment session.

What should you think about?

As with meditation, you need to subdue the mental chatter: those thoughts between your conscious mind and subconscious mind. You may not know or notice it but there are lot of things going on in your mind even though you may not be fully conscious of it. Stop whatever you are doing for several seconds and try to listen to what's going on in your mind, A lot right? Thoughts about worries, fears, relationships, etc.. are always competing with each other for attention. A majority of these thoughts are negative in nature and being so can induce stress in your body thereby draining you of energy.

To focus your mind on only one thought, say an image of an apple, is one technique to subdue the mental chatter. If you notice you mind drifting away from the apple, you can consciously go right back to it. This technique may sound tiresome due to the fact that you are concentrating on something, the fact is it requires less energy to consciously think of only one thing than to unconsciously think of many things. The problem with tthis technique is that not everybody is good at imagining an image. This is where isochronic tones are better because all you have to focus on are the tones which can and effectively eliminate the mental chatter aside from entraining your brainwaves to a target frequency.

Entraining to brainwave frequencies in alpha, theta and delta takes you more to your unconscious mind and lessens your conscious awareness. What goes in your unconscious mind can be influenced by the dominant thoughts of your mind before the entrainment. The same is true before going to sleep. It is evident in your dreams, if you have intense thoughts about a specific matter whether it's negative or positive just before going to sleep, your dreams may reflect similar emotions.

I strongly suggest that you bring yourself to a higher vibration before a brainwave entrainment session. By higher vibration, I mean positive emotions such as love, joy and peace. Remember those times when you were elated, in love or happy - bring those emotions to the present and you'll surely reap the benefits for the entrainment at lower brainwave frequencies.

That's all you need for now if this is your first time in brainwave entrainment. Later on I'll post topics on attracting what you want in life using isochronic tones as a vehicle for it's attainment and manifestation.

How to choose a carrier frequency

Choosing a Carrier Frequency

What carrier frequency or pitch to use in your isochronic tones?

Practically any frequency in the audible range can be used (20hz to 16000hz). That's a lot to choose from!

From my experience, what's pleasant to the ear is to use a carrier frequency which is a harmonic of the isochronic tone. The harmonic frequency is calculated as:

isochronic tone X n, where n is the no. of harmonic

As an example, if your isochronic tone frequency is 10hz (alpha range), the harmonic frequencies are:

10hz X 2 = 20hz (second harmonic)

10hz X 3 = 30hz (third harmonic)

10hz X 4 = 40hz (fourth harmonic)

.....and so on

We can modify our previous projects on isochronic tones: square waves and sine waves, to make it more pleasant to hear using any of the following harmonics of 10hz.

20, 30, 40, 50, 60....190, 200,....

You may first want to experiment with a carrier pitch that you would like. There are people who prefer the low frequency range and others prefer a higher pitch. Generate different tones using the audacity software mentioned in the square waves project so that you can 'preview' the carrier frequency and decide what seems nice for you.

Once you find the carrier frequency that's nice to hear for you, you can then create a more pleasant isochronic tone.

The next project will be on creating ramps. If you're targetting an isochronic tone for a theta brainwave entrainment, it's best to start in the alpha and ramp down to your target theta frequency.

Create Isochronic Tones Using Sine Waves

If you followed the first project, isochronic tones with square waves, you may not like the sound it produces but it's very effective in entraining the brain to produce alpha waves.

For our next project we'll create another tone using sine waves which are a little bit friendly to the ears. The pitch or carrier frequency  and the isochronic beat will be the same as the previous project.

  • pitch or carrier frequency: 194.18hz
  • isochronic beat: 10hz

The image below will be our target isochronic waveform.


isochronic sine waveform

If you haven't already done so, open the audacity audio editor.

1. Click Generate/Tone..

2. Enter the data you see in the image below:

generate sine wave isochronic tone3. Click Generate Tone. You'll see the following waveform:

half wave isochronic tone sine wave

The waveform is quite different from the previous project. You can adjust the display to your needs by zooming in our out. Here are the menu and keyboard equivalents:

FUNCTION MENU KEYBOARD SHORTCUT
zoom in View/Zoom In Ctrl+1
zoom out View/Zoom Out Ctrl+3
normal View/Zoom Normal Ctrl+2

Although this waveform is more pleasant than the square wave, we can make it more pleasant by fading it in and out. Here's how to do it:

  • Press Ctrl+a to select the whole track.
  • Click Effect / Cross Fade In
  • Click Effect / Cross Fade Out
  • Click Effect / Normalize...leave the check marks on the two checkboxes from the dialogue box. Click Ok

You'll get the following waveform:

half cycle isochronic sine wave fadeinout

Notice the abnormal waveform somewhere at the end of the track. We'll clean that up after we generate the silence part.

4. Generating silence

The silence or no sound portion should be the same length as the tone. Go to the end of the track by clicking Edit/Move Cursor../to Track End. The keyboard shortcut is the End key.

Now that we have the cursor at the track end, it's now to insert silence of the same duration (0.05 sec.). Click Generate/Silence... and a dialogue box would prompt you for the length of silence in seconds. Enter ".05" without the quotes then click Generate Silence. Zoom out the track and you'll see the waveform like the image below.

isochronic tone-one-cycle-raw

Let's clean up that abnormal waveform in the center. What we'll do is to silence that part so that the tone will sound good, leaving that alone will produce an annoying click sound. Here are the steps:

  • Highlight the area by clicking somewhere on the left of the abnormal waveform and dragging the mouse to the right of it.
  • Zoom in so that the abnormal waveform will be magnified. Now you will know what area to silence.
  • Highlight the abnormal area to select it.
  • Click Effect / Amplify...
  • At the dialogue box, drag the slider all the way to the left then click OK.

Zoom out the view and the waveform should now look like this:

isochronic tone one cycle sine clean

That's it, you can now replicate that waveform till you reach your required length of iso tones.

5. Replicating the full wave - same as the previous project.

Select all of the items in the track by clicking Edit/Select All. The keyboard equivalent is Ctrl+a. Now that the whole cycle is selected, copy it to the clipboard by clicking Edit/Copy - keyboard equivalent is Ctrl+c.

Bring the cursor to the track end by pressing the end key then paste the contents of the keyboard by clicking Edit/Paste or pressing Ctrl+v. Do this sequence 9 times to create a 1 second tone.

Copy all of the 1 second tone to the clipboard and paste it 9 times to get a 10 second tone.

Copy the the 10 second tone to the clipboard and paste it 5 times to get a 1 minute tone and so on....

The tone should be a lot better to listen that the square wave version.

6. How long should the tone be?

Studies have should that you can entrain your brainwaves to a specific frequency within 6 minutes depending on where you brainwave was pulsating before you started listening to the isochronic tone. If you are already relaxed when you start listening, your brainwave can be entrained earlier compared to being in an active state before the start. 15 minutes is a good length of time for relaxing purposes.

After you have created your desired length of isochronic tones, you can now export it as a .wav file. Click File/Export as Wav.. A dialogue box will prompt you for a filename and the location for the file.

On meditation

Meditation can give a lot of benefit for your mind, body and soul. To get into a meditative state requires a lot of practice and it could take months to experience the benefits of meditation. The idea of meditation is to reach the alpha or theta state and stay there for a length of time. It's the state of being between waking and sleeping. The alpha brainwave state is nearer the waking state while the theta brainwave state is nearer the sleeping state. We normally pass those states when we go to sleep spending just a little time in those states before falling asleep. In meditation, you extend that length of time in those states thereby reaping the benefits of being in that state.

There are many techniques of getting into a meditative state: thinking of only one thing, counting backwards, tensing and relaxing your muscles...and so on. After you have successfully reached that state, the problem now is maintaining or staying in that state. We will either fall asleep or get back into beta or waking state.

The beauty of isochronic tones can bring us to the meditative state in a much shorter period of time and staying in that state longer. Say you're entraining for an alpha frequency of 10hz: if you'll get sleepy, the tones will pull you back to the alpha brainwave since your brain is already entrained to that state and is the dominant brainwave frequency. Likewise if you snap back to beta because of a disturbance such as a loud noise, the tones will also pull you back to the alpha state.

I'll talk about the influence of the conscious and subconscious minds during meditation later. Meanwhile enjoy your newly created isochronic tones.
