The message is telling you that audiere.dll does NOT define the
mandatory function named 'initaudiere' which it should absolutely
define to allow the "import audiere" statement. If the import
works fine outside of a py2exe'd environment but fails in the
latter then I suspect you may be getting the "wrong" DLL in the
second case (e.g. maybe you didn't copy audiere.dll to the
directory in which py2exe's tweaked import expects to find it).

Thanks Alex for the reply, but if the audiere.dll has been copied in the dist/app/ directory (the one with the .exe) doesn't it mean
that py2exe find it?
Maybe i have to copy manually the dll ?

If audiere.dll is in the right directory, and it has the
initaudiere function in it, your behaviour is rather mysterious.
Perhaps you have some other file of the same name on your
machine and import is picking up THAT file instead (under
py2exe only) -- just guessing, of course.

audiere.dll and .pyd are in my DLL python folder (as suggested in the info page of the project), but they also are in the dist
folder..
I checked for duplicates but they didn't exist.. I also check the files copied (.dll and .pyd), are ok.
I also used the force-import argument in the setup.bat file, but nothing changed :(

The .exe file will not be for distribution, just for me.. so i can use always the .pyw file.. no problem, but maybe in the future i
will find the same situation

Name your extension module other than the DLL you wrap with it. E. g.

pyaudiere.pyd => audiere.dll or
_audiere.pyd => audiere.dll

Anything else is creating real or potential problems you'd want to avoid.

In your case I'm pretty sure Python tries to load "audiere.dl l", which
of course doesn't export the initaudiere module initialization function,
so you get the error you, uhm, get :-)

in this way I receive the message:
ImportError: dynamic module does not define init function (initaudiere)

also launching the .pyw file
