.SH "DESCRIPTION"
.PP
\fBwvunpack\fR
decodes WavPack files back to their original uncompressed form using the options provided\&. Unless overridden with the
\fB\-o\fR
switch, the output filename will be identical to the source filename but with the original file extension replacing WavPack\*(Aqs
\(lq\&.wv\(rq
extension\&. It is also possible to output raw audio without headers (see
\fB\-\-raw\fR
option)\&. Multiple WavPack input files may be specified resulting in multiple output files, and in that case
\fB\-o\fR
may be used to specify an alternate target directory\&.
Stdin
and
stdout
may be specified with
\(lq\-\(rq\&. It is also possible to export to one of the alternate file formats listed below, but in that case the information in the original headers and trailers will be lost (even if the alternate format is the same as the source format)\&. WavPack files are generally created with the
\fBwavpack\fR
program\&.
