Create A Custom Frequency

Posted on by

If you’ve perused the Downloads on this site and haven’t found a remedy for a condition or ailment, you may want to create your own custom frequency audio file. Before you can create your own frequency audio file, you first need to know what frequency to use. The Consolidated Annotated Frequency List (CAFL) is a useful reference used primarily by the Rife community, to find frequencies that help with various conditions and ailments. After loading the CAFL into a browser window, you can use the browser’s “seach-in-page” feature (on Windows Control-f, for Mac Command-f) and search for a specific condition.

For example, lets say I have a headache. I search the CAFL for headache, and there are 12 entries that refer to headache. After looking at the 12 entries, I’ve decided to go with the following:

Headaches - 144, 160, 1.2, 520, 10, 10000, 304

According to some authors, PEMF works best at 32Hz or less. Given that, there are only 2 values that apply in this list, 1.2 Hz and 10 Hz. Since the 10 Hz frequency already exists in the Downloads, I’ve decided I want to try 1.2 Hz.

The frequency is the main piece of information you need to create your own custom frequency audio file. You also need to know what kind of audio you desire: MP3, Apple Lossless (ALAC), or Free Lossless (FLAC). There are some other optional fields in the online tool that are useful when create your own custom MP3 file. Here is a screenshot of the Create Custom Frequency tool:

Here are the definitions of the fields in the online tool:

  • Frequency is the frequency of your audio file. It must be a number greater than zero but less than or equal to 2400 (see the note below for an explanation of this number). You can use a number with a decimal point, say like 7.83 or 3.14159.
  • Wave Form is the wave form to use in creating the audio file. Pulse is the default wave, the least intense in term of magnetic power, but others are available for your experimentation. Pulse is a 5% duty positive offset only square wave. All other waves beside pulse are positive and negative offset. The next least intense wave is the Lilly wave. The other waves are sawtooth, reverse sawtooth, triangle, and sine.
  • Audio Format is the desired format of your audio file. For Apple and iOS products (iPod, iPhone, iPad), choose Apple Lossless (ALAC). For open source music players, like Android 3.1+ and Rockbox, or commercial players like RIM Blackberry, Cowon, Creative Zen, HiFiMAN, Sansa Clip family, TrekStor, iRiver, Archos, and Latte, choose Free Lossless (FLAC). If your music player cannot handle the other lossless formats, choose MP3, which is a lossy format. The ALAC and FLAC formats will offer no distortion and smaller download size, while the MP3 files are distorted because of the lossy compression.
  • Sample Rate is the sample rate used for your audio file. For MP3 files, the maximum sample rate is 48 KHz. For ALAC files, the maximum sample rate is 384 KHz, and for  FLAC files the maximum sample rate is 576 KHz.
  • Album Name is useful to help organize your  files. In the music world, this field specifies a song’s album name. For our purposes, this allows us to group our audio file by functionality or common property.
  • Track Name is the printed name of the song on your music player’s user interface. For musical audio files, this is the name of the song.
  • Track Number is the numeric value used by music players to order the songs in an album. For our purposes, its best to start at 1, and increment for each new song you add to the album.

Once you have your frequency you want, and perhaps the optional fields, click the following link: Create Custom Frequency. Fill in the form values on this page and click the Create button. If there are no errors in the form, in a moment a new zip compressed audio file will download to your computer. Take this zip compressed file, decompress it (this functionality is standard for Windows and MacOS), and then download it to your music player to enjoy the new frequency.

If your frequency you want to use is greater than the maximum frequency supported by your audio file format, you can click the Fix Frequency button to get an octal subharmonic of your frequency that is in the valid range. The software divides the  frequency by 2 until the value is less than or equal to the maximum supported frequency.

Maximum Frequency vs  Sample Rate and Wave Form.

Waveform 48 KHz 96 KHz 192 KHz 384 KHz 576 KHz
Sine, Lilly 2.4 KHz 4.8 KHz 9.6 KHz 19.2 KHz 28.8 KHz
Triangle 6 KHz 12 KHz 24 KHz 48 KHz 72 KHz
Pulse, Sawtooth, Reverse Sawtooth 12 KHz 24 KHz 48 KHz 96 KHz 144 KHz
Square 24 KHz 48 KHz 96 KHz 192 KHz 288 KHz

[June 1, 2014 Update] I’ve added ALAC and FLAC support.

[June 4, 2014 Update] Corrected the maximum frequency, now set at 2400Hz. The reason this maximum rate is so low is because to get the definition needed in the wave forms, 20 samples per cycle are needed. The pulse wave used in these samples is a 5% duty positive offset square wave, so 20 samples are needed to implement 5%-on versus 95%-off in the pulse wave. The sample rate of these audio files is 48000 samples per second, so the maximum frequency is 48000 / 20, or 2400 Hz. If you submit a frequency higher than 2400, the software will calculate a fundamental subharmonic, and suggest this subharmonic in an error message.

[June 7, 2014 Update] Documented the Fix Frequency button.

[June 17, 2014 Update] Documented new Wave Form radio button. The FLAC file format supports the highest frequencies, then the ALAC format, and the MP3 has the lowest maximum frequency support. For Sine and Lilly waves, 20 samples per cycle are needed. For Triangle wave, 8. For Pulse, Sawtooth, and Reverse Sawtooth waves, 4. For Square wave, 2.

  1. Not sure if you are still answering questions here – but if I used the basic DIY – mp3 model you’ve suggested here – can I use the 2×2 Array – Box Confiugration Coil Array –
    or will that cause too much heat .. or whatever else?

    Also, if anyone ever comes across this and will help me by building one of these – adding the “files” etc.. I’d be more then happy to pay some money for this!!!

    Thanks

    • I don’t have the 2×2 Array coil adapter, but looking at it, it looks like it directs the left and right channel to each coil, doubling the amount of PEMF energy. This ought to work, though since I don’t have the adapter, I can’t tell you definitively. You don’t need the 2×2 array to get a lot of the PEMF benefits like entrainment and improved blood circulation.

      By the way, each coil sets (2 coils) uses only one channel of the output signal. This is why the 2×2 Array can double the strength, since now the left and right channel are both in use.

  2. Hi Prana,
    very interesting site. I am interested in creating new frequencies that are not in a database so far. Do you have any idea on how to get those?
    Thanks for hints.

      • Currently, the way you can get higher frequencies into a lower resolution audio file is to use Square Wave instead of Sine Wave. If you want to allow higher frequencies, use a file format other than MP3.

    • When I use the first example you ever posted, and apply Fix Frequencies to it, I get a success message as follows: Frequency changes: 87240 -> 10905, 43018 -> 10754.5, 74523 -> 9315.375, 75691 -> 9461.375, 86684 -> 10835.5, 86695 -> 10836.875, 69659 -> 8707.375, 87240 -> 10905, 56366 -> 7045.75, 48120 -> 6015, 62745 -> 7843.125, 81154 -> 10144.25, 74040 -> 9255, 53384 -> 6673, 66378 -> 8297.25, 80202 -> 10025.25, 75982 -> 9497.75, 53414 -> 6676.75, 68131 -> 8516.375, 54219 -> 6777.375, 71886 -> 8985.75, 45757 -> 11439.25, 73120 -> 9140, 72703 -> 9087.875, 54952 -> 6869, 51505 -> 6438.125, 36149 -> 9037.25, 29787 -> 7446.75, 55602 -> 6950.25, 36104 -> 9026, 61471 -> 7683.875, 62006 -> 7750.75, 45570 -> 11392.5, 58907 -> 7363.375, 45806 -> 11451.5, 46905 -> 11726.25, 76198 -> 9524.75, 66540 -> 8317.5, 74047 -> 9255.875, 73221 -> 9152.625, 59585 -> 7448.125, 69227 -> 8653.375, 52481 -> 6560.125, 76505 -> 9563.125

          • Thank you. I think you figured out the problem in one of your later comments.

        • Hi Anko, I have now fixed this problem. You will be able to load your example program, and even a larger one, without this same script error. However, if you make the MP3 too large, it may not finish in a timely manner. Please, do not retry in rapid succession. Try to let the first one complete. Otherwise, you will hang the server forever and no one will be able to create MP3 files.

  5. Did not work :

    https://www.spooky2.com/forums/viewtopic.php?f=12&t=13512&p=142399&hilit=Script+failure+with+exit#p142399

    …..There sometimes is an error if the audio doesn’t download, the next time you create the file, if the first process is still holding onto the file, the new process can’t create it. So either the first process has to quit, or you can do the following: just reorder the frequencies in your list, this will create a different file name, and hopefully the download completes……
