"Noiseprint Magic"
To further show you incompatabilities in this audio file, I've done a noise research.
I took a noiseprint (basically, a print screen of a certain frequency range) from Part B, the alleged radio changing channels.
I then subtracted and extruded other noiseprints available in Part A and Part C basing the frequency range and shape on the noiseprint. Basically, I
had the module leave only the areas where this noise print from Part B (radio changing) is present.
And I got this:
What we see here is traces or coinciding patterns of the noise from Part B, which is different in all three parts. The frequency ranges are different
in all 3 parts.
Although there is a strange double line in Part A and B, and a single one in Part C, probably from mp3 encoding.
Has anyone recorded his radio? I really need it to continue on with my showing you the facts about this audio... BTW, where is the OP hiding...!?
UPDATE:
Aha! Got my brother's radio and recorded it switching from channel to channel slowly tuning in... Look what I got:
What we see here is that all clean radio signal is cut out above 15KHz, clearly seen in my picture where the radio is tuned. When the radio is not -
we get a noise pattern that is called white noise - going on in all the frequency space.
Also, evidencing that the channels come from one source - the radio - we got a nice little noise pattern up over the channels, at about 19KHz, which
is unheard, but goes on during the transmission. Marked red...
Almost there to calling this one a fabricated mix... where the # is the OP?
By the way:
If anyone is into Frequency analysis, has any Audio software, there are a bunch of Frequency analysis software products for free, too. Try to get the
secret message in this manipulated audio file.... you're in for a great surprise! (nothing subliminal, don't you worry
)

Whoever gets is get the secret prize! (14 days till link expires).
