First, I'm programming a tool for mp3 file analysis (vloume, genere, beat)...

But I'm stuck on the start...

As you know a music file is assembled from a number of samples per second (samplerate)...

I'm looking for a script that would fill all the samples from a file to an array.

Thanks for your help.

Basically, I'm looking for a class / algorithm that would get all sound samples inside a mp3 file to easy-readable structure (ex. array, list).

You are missing an enormous intermediate step:

MP3 files are highly compressed.  
You need an MP# CODEC (COder/DECoder) to convert the file into a
stream of audio samples.

Check out the open source LAME CODEC:

I wanted to use Wmp3, but it uses <windows.h> lib. It would probably suit me well.

I'm trying to analyze BpS (beats per second), melodics, genere (rock, metal, pop) und zo weiter.
