Introduction
MultiFreq generates multi frequency tones based on the compositions of different sine waves. Tones are generated in stereo sound, Left channel contains the generated wave and Right channel can be shifted in a certain amount of Hz completing the expression R=(hz difference) + L. Left to Right channel offset is subtracted by our brain balancing it to the corresponding effect, i.e. alpha-meditation, beta-creativity… Playing tones Each independent sine wave can be defined using Generating the wave Vol. x SIN (Hz + Phase) Up to 10 independent waves can be defined with the set of three scroll bars Once the wave is defined click on <Play> to hear the multifreq wave. |
You can now change the values of each wave and the tone will also change dynamically, during transitions you may hear some noise –this is normal-, it will disappear when releasing the scroll bars.
Right channel offset can be changed using the text box of the expression R=[edit]+L or by selecting the brain wave frequency difference in the top list box. Wave definition values can be calculated using the simple Worksheet at the right, columns correspond to (A-Hz, B-Vol, C-phase inº) values can be copied from/to wave control panel using the arrowed button next to it. Worksheet enables formula definition so you can set the content of B1: =A1*1.618, note that a formulas must begin with the ‘=’ character, there are many similarities with MS-Excel in the operation with this Worksheet. Keeping and retrieving configuration You can keep actual wave parameter configuration by selecting the <Keep> button, retrieving previously stored configuration is achieved by <Get> button. Saving tone to a .wav file Clicking the <Save> button a .wav file will be generated with the duration specified in right edit box in seconds. |

Now that you've (hopefully) read the basic instructions, we're going to
take a look at an actual example as shown in the screenshot (above).
What you see is a dual frequency setting of 50 Hz at 50% volume with 0-degree phase setting (channel 1) and 100 Hz at 50% volume at 180-degree phase (channel 2). This means the second channel is 180-degrees out of phase with channel 1. The sample is 60 seconds long with the right channel 12.5% louder than the left channel. The note produced is approximately middle C or 261.62556530061 Hz.
The lowest combination, as you can see in the chart at the right, is the "bowl-deep relax" setting, which is 10 octaves below the middle, barely into the threshold of human hearing. We can either play the note, keep the settings you see (saved as a .wmu file), get a new setting which has been previously saved, or save this tone as a 60-second .wav file. Let's listen to saved samples (converted to MP3 files for quicker loading) at different settings. |
You can even play more than one at a time and see how they interact with each other, creating additional harmonics not found in the individual tones. PURE TONE Download

SO HOW DO WE USE THESE?
Tools
you need: Audacity,
Reaper (4.5 Mb download) or other
Digital Audio Workstation (DAW) |
|
|
The examples above are saved to the Tone Library (you could create a
folder on your computer by this name or call it whatever you wish).
The next step is to open a file of your choice in Reaper or Audacity (these screenshots are from Reaper) and add a second track where you will insert a musical track, a track of nature sounds, rain, wind, ocean or whatever is appropriate. Drag the first track out to match the length of the second track (or however long you want it to be), save the project and then render (export) it to a .WAV or .MP3 file.
There are more detailed settings available for each track such as panning and more detailed volume settings (both available by clicking the TRM button on each track), although in the example you're about to hear I did not engage those settings.
Above is what the TRM settings control box looks like. I recommend arming either PAN or VOLUME (but not both), making your adjustments, then arm the second setting and making adjustments. (Pan settings are shown below). You can see that every 60 seconds the theta tone shifts from the right ear to the left. Example
of above track with panning effect |
Notice how the two tracks are mixed at different volume settings to allow the theta tone to barely be heard. In this case I needed to drop the volume of the music track. Then you get an example like this:
This is the theta wave example mixed with the "Glowing Sky" track from the Rainy Day Reflections CD in the Moods of Nature series (used here for education and research purposes under the provisions of the Fair Use section of the U.S. Copyright Act). You'll see above how I centered the theta tone within the musical track. Click here to listen to the same 6-minute piece with the panning effect (stereo headphones recommended).

It is blended with alpha waves to enhance meditation.
The [oct -5] notations tells us the alpha tone is 5 octaves below the
middle octave on a piano.
