Making or creating isochronic tones is easy if you have the right tools. The first thing you need is an audio editor software. there are audio editors which can generate tones and others can't.  What we need is the one which can generate tones. If you don't have one yet, there's a free audio editor called audacity which you can download at:

As of this writing there are two versions available. Download version 1.2.6 as it will be the version I will be using. The other version is still in beta and there are some aspects that aren't suitable for our purpose.

Once you have downloaded the installation files, install the software and explore it. Try opening audio files to see the waveforms. Explore the cut/copy and paste functions as we will be doing a lot of it in my next post.

We'll be using audacity for our projects. If you have another audio editing software which can generate tones, you can still follow the projects and just use the equivalent procedures for your software.


Why do we want to create isochronic tones? As you may have already read about brainwave entrainment, it is a way of making our brains generate a desired brainwave pattern which produces in our body and mind the benefits or "un-benefits" of that specific brainwave pattern. I would like to emphasize this early on to experiment only with frequencies which are mentioned in this website and other websites which have been tested and which have been known to do good for your mind and body.  Please see disclaimer below this page.

The goal of this website is to use, create or make isochronic tones to improve your well being. For example if you have a stressful daily routine, you can use isochronic tones to help you relax and keep in check the stress hormones (which may be harmful in the long run) which runs in your body. You may also want to access your deeper levels of mind that can enhance your creativity, attract what you want in your life - be it wealth, the girl of your dream, a house, a car, health, etc..

Many brainwave entrainment products which incorporate isochronic tones have been made. This website does not challenge the effectiveness of those products. They have been carefully researched and engineered to bring the utmost benefit for the users. This website only serves as an introduction to isochronic tones, to let a person experience whether it is effective or not in bringing about benefits for your mind and body. If you will notice beneficial changes to yourself when using these isochronic tones, then you may try the products which are created and designed for different conditions and states that you may need.

Only a single frequency at a time will be targeted in the examples that will be posted here. Don't try to mix different frequencies at the same time as we don't know what effect it will have to the brain. As you may know, the brain works only with one dominant brainwave pattern at a time - beta waves in the waking state, alpha waves in the relaxed state, theta waves in the sleepy state and delta waves in the deep sleep state.

The first project I will introduce to you is to create an isochronic tone which has the waveform you see in the picture below.

Isochronic waveform using square waves

That's the waveform produced using the audacity audio editor. As you can see, tones occur at intervals equal to the length of the tones. In later posts we'll be making isochronic tones with sine waves and some modifications to make it sound a little nicer.

What are Delta Waves?

Deep dreamless sleep is the stage when your brain produces the most delta waves. This
is the stage where your body heals itself: emotionally, mentally and physically. Growth hormones are also released for cellular regeneration. It is very important that we get our daily dose of delta waves. Restoration and rejuvenation are the main functions of this stage
aside from the deeper communication with our superconscious, higher selves, universal mind or whatever term you call it.

Do you remember those times when you wake up feeling groggy and unrefreshed? You may have been in delta when you woke up. A loud noise, a ring from the alarm clock or an itch can wake you up disrupting the delta wave portion of your sleep. The best time to wake up is when you are in theta or in the REM (rapid eye movement) stage. I'll discuss the stages of sleep in a later post.

Deep sleep is a combination of mostly delta waves (more that 50%) and theta waves. Other brainwaves also run in the background but in smaller amplitudes or strength. This state has the lowest frequency among the brainwaves, greater than 0hz to 4hz, but higher in amplitude or strength.

Below is a reproduction of a 1 second delta brainwave taken from an EEG (electroencephalograph).

Adults generate delta waves almost only in their sleep. Infants up to 1 year old spend most of their time producing delta waves even when awake. The delta waves in their wake state gradually lessens as the theta waves comes to the limelight followed by alpha and finally to the beta state when they become adults.

You may have noticed that children less than 7 years old has little attention spans. Focus and attention are characteristics of the beta wave and since the dominant brainwaves of a child are delta and theta, it's just natural for a child to behave this way. Have patience with children!

Our conscious mind has no control or influence during the delta stage. The unconscious dominates our minds while the conscious sleeps. However Buddhist monks, Zen masters or other meditation experts are said to achieve semi consciousness while in the delta stage. Maybe that's where they experience enlightenment. Perhaps with the aid of isochronic tones, ordinary people can also achieve this state.

What are Theta Waves?

Here lies the seat of deep meditative state. Rhythmic chantings of Buddhists monks allow them to reach theta state where they experience becoming one with the universe. Shamans reach their trance state to heal by the rhythmic beating of the drums. This rhythmic patterns fall within the range of theta waves (4hz-8hz).

Theta waves are observed during extrasensory perceptions, astral projection or any psychic activities.

Super learning can also be achieved in this state. Children especially pre-schoolers easily generate theta waves in their brain when they are engrossed in any activity. Ever wondered why children learn so fast? As children mature, their theta states become less frequent as the beta state become more predominant in their waking hours.

Theta waves occurs before deep sleep (delta waves) and you are actually semi-conscious in this state. Our conscious mind can examine our subconscious mind in this state but has little influence over what transpires. Vivid imagery can be experienced in this state. Have you experienced seeing vivid mental pictures when you are almost asleep? See clear images of people whom you have never seen before?

Addictions can be cured using this brain state. So are reprogramming deep seated beliefs, increasing creativity, super learning and many more things that your mind and body can benefit. It normally occurs before falling asleep and when we are engaged in a repetitive task or things that don't require our conscious attention (leaving that tasks to the automatic response of our subconscious). Driving a car in a long stretch of highway and all you hear is the purr of the engine or the wind creating sounds when it comes in contact with your car can also bring you into this state but very dangerous.

Theta state falls within the alpha state and the delta state. Theta waves lasts only a few minutes before you fall into deep sleep. One can extend the length of time you spend in the theta state and harness the benefits it brings to your mind and body. Meditation is one way but could take a lot of practice. Another way is by using brainwave entrainment techniques such as isochronic tones which your brain can easily move in step in just a few minutes.

alpha waves

What are Alpha Waves?

The boundary between waking and sleeping lies within the alpha waves. Taking a rest and relaxing can slow the frequency of your brain waves from beta to alpha. If left alone without interruptions (loud noise, mosquito bite, itchiness, etc..) your brainwaves will go slower and slower till it reaches the sleep states; theta and delta.

Reason and logic will start to lose domination of your mind as you begin the journey to the unconscious. This is the brain state where your mind strongly accepts suggestions since reason and logic is losing dominance in your mind to contradict or reject suggestions.

The alpha wave range (8hz to 12hz) has lower frequency values than the beta waves but has higher amplitudes or strength. Below is a reproduction of an EEG(electroencephalograph) of alpha waves in a span of 1 second.

The contents of your subconscious mind can be examined in the alpha state. If you can stay long enough in this state (half awake-half asleep), you can hear the voices or see the images of what your subconscious mind holds. You will be able to discern the dominant thoughts of your subconscious mind (negative or positive). Many have used this state to their advantage; healing, creative visualization, attracting wealth, and so on. Watch out for my posts about these subjects later on.

Holding on to this state for a longer period of time could be a task for the inexperienced. But with practice such as meditation, holding on to this state for several minutes is achievable in a few months. You can however, entrain your brain to generate alpha waves and stay there for a much longer period of time achievable in only a few minutes using isochronic tones. More on this on later posts.
