Subject: Fundamental Frequencies proven by FFT module
Hello everyone,
I have activated the attachments to send you these graphics, and after deactivated again the possibility to send
attachments to be sure we do not receive virus via this forum. I hope you all can see these graphics from the
BIOSONIC new FFTmodule.
Many times I have written in the forum that the way to process the wav by the Biosonic system is revolutionary and
it is taken from the wav not FFT.... This allows us to capture the real vowel sounds coming from the vocal chords
not the silent of hissing sounds of the consonants... These vowel sounds are the fundamental frequencies that we
now have in the actual Biosonic program. We needed to create the FFT module to be able to prove it, and how
the fundamental frequencies create harmonics shown as other mounds, going into higher octaves that we call harmonic
cascades.
ON the first graphic we can prove that we do have that new a revolutionary method to pick up most of the
fundamental frequencies that come from the vocal chords, pure sounds of the vowels. What you see in the first mound
is the fundamental that coincides with the high peak of the note in the colorgram and the other mounds are the
harmonics. IN some voices or waves we might have hits or numbers above the main octave and they could be as
high in amplitude as the fundamental or even higher, that is how some harmonics do hits into the chromatic style
too. What everyone has to finally understand is that we have invented a way to read it from the wav and
capture most of the fundamentals in the chromatic, and now we can prove it with the FFT.
I also send you some graphics,, a button with the word FFT changes the wav graphic above to the FFT and then you
can enlarge it and see it alone too. When the above window is for FFT you can select with circles the cellboxes
from notes or octaves that you desire to have the FFT and click on FFT button again and in a little while it will
calculate it. THe important thing is that the same high frequency in the colorgram is the first mound of the
FFT and then you can study the harmonics.... IN the full FFT with all the unwanted data there is no way to study
the harmonics....
So these are also other graphics of the FFT... it is very different from what you have seen before, it takes it
from the chromatic and has already taken all noise and unwanted data, it also can prove that the chromatic has the
fundamental frequency and it does coincide the frequencies of the FFT with the frequencies of the Colorgram. One
can do an FFT of one note, or of the Main octave only, or just one cellbox. can mark the cellbox in the chromatic
grid or in the colorgram with frequencies and just do the FFT of that. Later on we will program for us
to have the full FFT like Oneness does, but we know that it has too much of unwanted data and it is too confusing
... we have to get used to this and see what we want.... It will take quite a while till it is ready for the public
and it will change a lot from what is shown now...
I hope you understand these images. Please ask any question you
love
Marysol
