Hello!

I'm a musician from northeastern Pennsylvania; I just stumbled across your forum/site, as well as the concept of Isochronic tones. I have experimented with binaural beats in the past, and am now conducting home experimentation in both Isochronic & binaural (Trying to get to the 'territories' haha).

Anyways, I am having a rather difficult time finding any documentation on Isochronic tones, other than some commercial products some company has blanketed the web with. I am downloading the starter pack as of right now so I can get a sample feel to how these waves are constructed, but from what I gather, they are pulse sine waves followed by equal amounts of silence (yes, a rough description).

Here's my question/problem: Let's say I want to create a 7Hz tone. In binaural beats, this is rather easy, as it's just a matter of subtraction between the left and right hemispheres. Using Pulse Sine, I'm not quite clear how one can create a tone that is audible using a tone as low as 7Hz.

I have many years of experience within the audio fields, as well as lots of research time available, the complexities of putting this together using audacity or something similar is not really an issue for me (This is in response to another post I read where a question was asked about building isochronic waves, and the answer was something similar to 'too complex, just buy so-and-so').

So basically, any help in the construction of isochronic would be greatly appreciated, particularly on the issue of low frequencies such as 7Hz.

Anyways, Thanks!

Hello scribe, and welcome to the forums.

Working with audio isn't exactly my thing, my work is on the mind. But for what it's worth, i hope this helps

It is a pain in audacity but basically you will want to have 7 sine waves per second. So to do this manually you must do a bit of algebra. Basically you will make a sine wave cycle to repeat every 1/7 of a second. If you're unsure try opening a file like 14 Hz and listening and comparing it to a file in audacity using 1/14 second pulses and it should sound the same. It's been very long since I've done this and I may have the technique wrong because of this but try it and report back. Good luck!

With isochronics, it's not about the pitch of the note (because most people can't hear below 20 or 30Hz), it's about the pulses per second. You could have a 200Hz carrier frequency (I think that's the correct term), but the entrainment depends on the manual spacing of the tone (beep---beep---beep), not the pitch at which it plays.

Although you can get entrainment using any carrier frequency, there are certain pitches that work better.

Please correct me if I am wrong, I don't wish to give out false information. I don't know a ton about the creation of these tones, but that is what I am getting out of what I have read.
