Debian                                          November 2, 2014                              SNDFILE-SALVAGE(1)

       Audio  files  using  the  WAV  file container are inherently limited to 4G of data size fields in the WAV
       header being stored as unsigned 32bit integers.  Many applications have trouble with these WAV files that
       are more the 4G in size.  sndfile-salvage rewrites the WAV file into a  W64  file  with  the  same  audio
       content.  This file is overwritten if it already exists.

       The sndfile-salvage utility exits 0 on success, and >0 if an error occurs.
