So I have an mp3 file (stereo, 44100 Hz) which I decoded with mpg123 and got a 32-bit float array. Now I want to write this array to .wav file and play it.

What I have tried:

I found several solutions in Java but they all used the tools from Java libraries

You must understand the wave file format specifikations to write the data.

But at first you must know which parameters your float array has to write the data in the wav file. First write some boilerplate information and than the RIFF and fmt chunk with correct data for the appended sound data.

If you have problem than you better contact some developers from the mpg123 folks.
