NAME
wvunpack — decode wavpack encoded files
SYNOPSIS
wvunpack [-options] [-o output] file ...
DESCRIPTION
wvunpack decodes WavPack files back to their original uncompressed form. Unless overridden with the -o
switch, the output filename will be the source filename with the original file extension replacing
WavPack's “.wv” extension. It is also possible to output raw audio without headers using the --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. A filename of “-” specifies stdin or
stdout. It is also possible to export to one of the alternate file formats 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.
If multiple input files are specified with piped output (“-o -”), then the output from all the files is
concatenated. This can be utilized as an easy way to concatenate WavPack files (assuming the output is
subsequently piped into wavpack), but only makes sense with raw output (--raw) to avoid headers being
interleaved with the audio data.
On multicore machines wvunpack will attempt to use multiple threads to speed up the operation, often by
3x or more. To force single-threaded operation use the --no-threads option, or use the --threads option
to fine-tune the number of threads utilized.
OUTPUT FORMATS
• Microsoft RIFF (“.wav”), force with --wav, creates RF64 if > 4 GB
• Sony Wave64 (“.w64”), force with --w64
• Apple AIFF (“.aif”), force with --aif or --aif-le
• Apple Core Audio (“.caf”), force with --caf-be or --caf-le
• Raw PCM or DSD (“.raw”), force with -r or --raw
• Philips DSDIFF (“.dff”), force with --dsdiff or --dff
• Sony DSD Stream (“.dsf”), force with --dsf
OPTIONS
--aif, --aif-le
force output to Apple AIFF (or AIFF-C/sowt), extension “.aif”
-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 for 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)
--no-overwrite
Never overwrite, nor ask to overwrite, an existing file. This is handy for resuming a cancelled
batch operation and obviously cannot be mixed with the -y option.
--normalize-floats
normalize float audio to +/-1.0 if it isn't normalized already (rarely the case, but alters audio
and fails MD5)
--no-threads
force single-threaded operation, equivalent to --threads=1
--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 already 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
--raw-pcm
similar to -r and --raw above except that DSD audio will be converted to 24-bit PCM (8x
decimation)
-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)
--threads=n
Enable (or disable) multithreaded operation with n=1 (no threading) to n=12 (max threads).
Significantly improves performance of all modes, including verify. Omitting the parameter will
select an optimum number of threads.
--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 into a named file in the same directory as the 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")
