Free sound generator similar in effect to i-Doser

    What is i-Doser many know, but I would like to be able to experiment freely in creating tracks myself. For this, you can use, for example, Python.

    As already mentioned, the i-Doser effect is most likely based on the fact that each ear has its own sound, and the brain perceives the frequency difference of these sounds. Listening to a couple of examples showed that this is approximately true. By the way, the commonplace addition of two sinusoids clearly shows why this happens: To create a stereo signal, I used the audiolab package , which also requires the libsndfile library. The result is such a “ program

    With its help, you can directly play the resulting sound (unfortunately only on Linux and Mac OS X) or write it to a file.

    The program needs to set the frequency of the main oscillation, and the frequency of the oscillation with which you want to "influence the brain." It is also possible to adjust the background noise, sample rate and playback duration, for more details: “python --help”

    Of course, you have to choose the frequencies yourself. It’s not difficult to write any more advanced combinations, for example, experiment with increasing the “difference” frequency with time, with alternating different sounds, you just need to understand python. With this approach, it will be possible to distribute not sound files, but simply python scripts. If someone is interested and finalizes the script, then it will be possible to divide it into the “core” and “playback script files”.

    Launch example:
    python -time 180 --freq 90 --diftone 2 demo.wav
    Such a launch option will create three minutes of low-frequency oscillations (60Hz), at which a frequency of 2Hz “affects” the brain (the same as that of delta oscillations in the third or fourth phases of sleep). The resulting wav can be encoded with your favorite codec. If you do not write the file name, then the script will try to output the sound to your speakers / headphones.

    In i-Doser tracks, sometimes the carrier frequencies change with the difference constant, sometimes all frequencies change, but this happens quite rarely, so you can simply create different files and play them in turn. Or, if you know Python, everything can be “fixed” in the program itself.

    PS i-Doser has practically no effect on me, except the following option helps a little to think about nothing: low-frequency “carriers”, and the “difference” frequency more or less coincides with the heart rate.

    It turns out that PPS i-Doser uses SBaGen developments , in which there is some kind of file format, a community discussing various rhythms, etc.
