Being NOW AWARE of THIS ABOVE playback conversion back to Real Speed We KNOW the Real Antidote .
.. As Of Today 2025/03/12
" We The People " .. should be filing .. a Multi Trillion Dollar law suit ? against Media Networks ?? in the United States and the World for TOTALLY UNNECESSARILY ? causing Massive ( Subtley Unnoticed ? ) Noise Pollution in the form of Mild ? Global Sonic Earritation affecting Everyone on the planet ADVERSELY WITHIN our Hearing .. Mental Health and Physical Wellness BY THE INDUSTRY NOT playing AUDIO Everywhere at the PROPER Playback Rate that In All HONESTY and PURITY SHOULD HAVE MATCHED that of a LIVE REALTIME .. Performance rate ( Calibrated ) SINCE THE DAWN OF AUDIO RECORDING TECHNOLOGY Instead the audio has ALWAYS been played at a FASTER than CORRECT True Reality rate Now take all that lawsuit money we win .. AND FUND people to PROPERLY FIX THIS SPEEDING PROBLEM E V E R Y W H E R E O N   T H I S   G L O B E
The formula for a 12 tone even-tempered scale
is as follows:
sin(2*f*((2^(1/12))^(x+(12*y)))*pi*t)
where f = 400 Hz ( middle A as A4 )
for my natural tuning system
x = relative note to middle A
y = relative octave to middle A
Any note can then be generated using
Goldwave software ( goldwave.com )
under menu option
Tool --> Expression Evaluator ...
You must first create a New Sound using
File --> New ...
Number of channels: 1
( mono )
Sampling rate: 39690 Hz
( actual music industry digital recording rate before speed up )
Initial file length (HH:MM:SS.T): 1:00
( one minute )
then create the wave from scratch in Expression Evaluator,
entering the formula shown on this page and saving as a preset.
Set parameter y to 400 Hz, then vary parameters x and y
as positive or negative whole integers.
click OK to actually generate the desired wave,
Finally you save the wave using
File --> Save As ...
end research
and electricity would be healthier at 50 Hz
which is an even multiple of the 400 Hz.
Accuracy of Goldwave is correct.
Kawaii ES-1 reads A 400 as tuned to 400 Hz
but you have to play A flat to match goldwave
so the keyboard is not calibrated correctly is one half step too high !!!!
I can correct the ES-1 by tuning it to 400 Hz
( Touch + Transpose ) + F' + F + E' + E'
where ( ) = simultaneously
where ' = the higher octave of the special keys.
To simulate the EBS ( Emergency Broadcast System )
two-tone signal using this tuning.
Play simultaneously notes A5 and B5.
This was determined from original frequencies of
853 Hz and 960 Hz which if you set middle A ( a4 ) = 426.5 Hz,
that makes 853 Hz ==> A5 and 960 Hz ==> B5.
There is a slight difference in pitch because this tuning
is designed for middle A ( A4 ) = 400 Hz
which i believe is a more natural tuning for biological organisms.
The two-tone effect is comparable and more pleasant.
Car Horns ( naturally based ) should resonate at an even 400 Hz ( A4 )
to be more pleasant sounding rather than some industry standards
which have the frequency set to 395 Hz.
