This work is a preliminar proof of fraudulent audio conversation editing.
I have spotted a difference in here.

First question - Is this white noise or pink noise? (ambient noise).
Second question
I need to measure the yellow arrow range intensity with values.
And I need to give the other values for the blue arrow range.
The red arrow is where I spot with my ears that it is probably an edition crop.
How to do that in Adobe Audition, selecting each range? Getting the numbers... or more graphs.
I don't know if this should have been posted in the CD software section, but this is not about CD, and there is no software audio section only, so forgive me if I have posted in the General Audio. Feel free to move to the appropriate sub-forum.
Thank you experts!

"Proof" would be a stretch. Maybe you can say "evidence". And, if you can detect it you can probably cover it up. ...You could also get a false result if the air conditioning/heating comes on, or if someone opens/closes a door or anything else that could change the character of the sound or the background sound.

Pink noise is more "natural" so probably closer to pink.

If you're not a programmer you'd probably need something like
MATLAB (https://www.mathworks.com/products/matlab.html) that can do
FFT (https://en.wikipedia.org/wiki/Fast_Fourier_transform) (or one of the free MATLAB clones). But, even with MATLAB (which I've never used) you'll still need to do some serious math and you'll need to understand something about the algorithms.
P.S.If this is related to legal/courtroom evidence you should probably consult a lawyer. You could be wasting your time, or maybe a lawyer can give to some tips help make whatever you are doing admissible.
You are right. Proof was inadequate. Evidence is more likely. The conditions you described also could influence the background noise. I will look into these programs. This is related to what you said. I could be wasting my time. I will see. Thank you for this answer!
