of the code to work properly (or perhaps i also confuse on that but
Python rely on interpretation of the code to conform to its own
standard, ie variables can change type during execution...)

Using compile() function yes.
So yes there is a way to check "syntax error" before executing code
(using compile function and exceptions) but it was not standard, nor
widely used... It was still a hack for me, but perhaps
uested but that only a
hack and should not be used in real world.

i'm not a math expert, but the limit of atan2 would be 45°, so pi/4
radians (0,7854).
As x,y are coordinates, the both infinite would tend toward 45°.
x only infinite would be 0° (0 radians)
y only infinite woudl be 180° (pi/2 radians)

yes of course if you pass an invalid argument (NAN is not a real value,
atan2 except coordinate x,y), the result would be invalid...

For the audio analysis i thought the module must be written in C or
