DESCRIPTION¶
wvunpack decodes WavPack files back to their original
uncompressed form using the options provided. Unless overridden with the
-o switch, the output filename will be identical to the source
filename but with the original file extension replacing WavPack's
“.wv” extension. It is also possible to output raw audio
without headers (see --raw option). Multiple WavPack input files may
be specified resulting in multiple output files, and in that case -o
may be used to specify an alternate target directory. Stdin and stdout may
be specified with “-”. 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 wavpack program.
•Microsoft RIFF, extension “.wav”,
force with -w or --wav, creates RF64 if > 4 GB
•Sony Wave64, extension “.w64”,
force with --w64
•Apple Core Audio, extension “.caf”,
force with --caf-be or --caf-le
•Raw PCM or DSD, extension “.raw”,
force with -r or --raw
•Philips DSDIFF, extension “.dff”,
force with --dsdiff or --dff
•Sony DSD Stream, extension “.dsf”,
force with --dsf
OPTIONS¶
-b
blindly decode all stream blocks and ignore length
info
-c
do not decode audio but instead just extract cuesheet
stored in APEv2 tag to stdout (equivalent to -x
“cuesheet”)
-cc
extract cuesheet stored in APEv2 tag to source-name.cue
file in same directory as decoded audio file (equivalent to -xx
“cuesheet=%a.cue”)
--caf-be, --caf-le
force output to big-endian or little-endian Core Audio,
extension “.caf”
-d
delete source file if successful (use with
caution!)
--dff, --dsdiff
force output to Philips DSDIFF, DSD audio source only,
extension “.dff”
--dsf
force output to Sony DSF, DSD audio source only,
extension “.dsf”
-f
do not decode audio but simply display summary
information about WavPack file to stdout in a machine-parsable format (see
doc/wavpack_doc.html or cli/wvunpack.c in repository for format details)
--help
display extended help
-i
ignore .wvc file (forces hybrid lossy
decompression)
-m
calculate and display MD5 signature; verify if
lossless
-n
no audio decoding (use with -xx to extract tags
only)
--normalize-floats
normalize float audio to +/-1.0 if it isn't already
(rarely the case, but alters audio and fails MD5)
--no-utf8-convert
leave extracted text tags in UTF-8 encoding during
extraction or display
-o OUTFILE
specify output filename (only if single source file) or
target directory (must exist)
-q
quiet (keep console output to a minimum)
-r, --raw
force raw PCM or DSD audio decode by skipping headers
& trailers, results in source-name.raw
-s
do not decode audio but simply display summary
information about WavPack file to stdout
-ss
do not decode audio but simply display summary and tag
information about WavPack file to stdout
--skip=[-][sample|hh:mm:ss.ss]
start decoding at specified sample or time index,
specifying a - causes sample/time to be relative to EOF
-t
copy input file's time stamp to output file(s)
--until=[+|-][sample|hh:mm:ss.ss]
stop decoding at specified sample or time index,
specifying a + causes sample/time to be relative to --skip
point, specifying a - causes sample/time to be relative to EOF
-v
verify source data only (no output file created)
-vv
quick verify (no output, version 5+ files only)
--version
write program version to stdout
-w, --wav
force output to Microsoft RIFF/RF64, extension
“.wav”
--w64
force output to Sony Wave64, extension
“.w64”
-x “Field”
do not decode audio but instead just extract the
specified tag field to stdout
-xx “Field[=file]”
extract the specified tag field to named file in same
directory as decoded audio file; optional filename specification may contain
%a which is replaced with the audio file base name, %t replaced
with the tag field name (note: comes from data for binary tags) and %e
replaced with the extension from the binary tag source file (or
“txt” for text tag).
-y
yes to overwrite warning (use with caution!)
-z[n]
don't set (n = 0 or omitted) or set (n = 1) console title
to indicate progress (leaves "WvUnpack Completed")
