Hi all !

I am trying to calculate the replay gain from Python, have tried over and over again, and failed miserably ...
I figured that would be the best place to ask, but if it isn't please redirect me smile.gif

I am using the shared object "libreplaygain.so" and what happens is that whatever data I give to `gain_analyze_samples`, `gain_get_chapter` always returns 80.000 ...

Here is the script I am using for testing : http://pastebin.com/4ngNuDZP
EDIT : here is a simpler version of the same snippet using scipy to read the sound file : http://pastebin.com/C7AWiGC6

I've really tried everything, and I am a bit desperate now sad.gif . I am not very good with C, and don't really understand what's going on with "ctypes", so I guess that might be a problem with value types. Hopefully the problem might be obvious to some of you?

Thanks,

Sébastien
