I tried to normalize some 32 bit foating files of cubase with the batch file of Peak 4 He saved it in 16 Bit with white noise. It was originals files!!! Cubase show it as 32 bit cut at the half of the file with distortion!!! What can i do? Is it irreversible?

The 32 bit floating point files created in Cubase are specific to that program - they can't be used in any other application. To convert them to 16 bit, use Cubase itself.
