NAME
wavpack - encode wav files to wavpack
SYNOPSIS
wavpack [-options] INFILE... [-o OUTFILE]
DESCRIPTION
wavpack encodes the specified source file(s) into WavPack files using
the options provided. The source files may be uncompressed WAV files,
existing WavPack files, or raw PCM data. The resulting filename will be
source-name.wv unless overridden with the -o switch. Multiple input
files may be specified resulting in multiple WavPack files, and in that
case -o may be used to specify an alternate target directory. Stdin
and stdout may be specified with “-”. In the case of transcoding from
existing WavPack files, all tags are copied (and may be modified with
additional args) and unless an alternate name or directory is
specified, the source files are safely overwritten. To decode WavPack
files back to wav or raw PCM use the wvunpack program.
OPTIONS
-a
Adobe Audition (CoolEdit) mode for 32-bit floats
--allow-huge-tags
allow tag data up to 16 MB (embedding > 1 MB is not recommended for
portable devices and may not work with some programs including
WavPack pre-4.70)
-bn
enable hybrid compression, n = 2.0 to 23.9 bits/sample, or n =
24-9600 kbits/second (kbps)
--blocksize=n
specify block size in samples (max = 131072 and min = 16 with
--merge-blocks, otherwise 128)
-c
create correction file (.wvc) for hybrid mode (results in 2-file
lossless compression)
-cc
maximum hybrid compression (hurts lossy quality & decode speed)
--channel-order=list
specify (comma separated) channel order if not Microsoft standard
(which is
FL,FR,FC,LFE,BL,BR,LC,FRC,BC,SL,SR,TC,TFL,TFC,TFR,TBL,TBC,TBR);
specify “...” to indicate that channels are not assigned to
specific speakers, or terminate list with “...” to indicate that
any channels beyond those specified are unassigned
-d
delete source file if successful (use with caution!)
-f
fast mode (fast, but some compromise in compression ratio)
-h
high quality (better compression ratio, but slower encode and
decode than default mode)
-hh
very high quality (best compression, but slowest and NOT
recommended for use on portable playback devices)
--help
display extended help
-i
ignore length in wav header (no pipe output allowed)
-jn
joint-stereo override (0 = left/right, 1 = mid/side)
-m
compute & store MD5 signature of raw audio data
--merge-blocks
merge consecutive blocks with equal redundancy (used with
--blocksize option and is useful for files generated by the
lossyWAV program or decoded HDCD files)
-n
calculate average and peak quantization noise (hybrid only,
reference fullscale sine)
--no-utf8-convert
don't recode passed tags from local encoding to UTF-8, assume they
are in UTF-8 already
-o OUTFILE
specify output filename (only if single source file) or target
directory (must exist)
--optimize-mono
optimization for stereo files that are really mono (result may be
incompatible with very old decoders)
-p
practical float storage (also 32-bit ints, no longer technically
lossless)
--pair-unassigned-chans
encode unassigned channels into stereo pairs
-q
quiet (keep console output to a minimum)
-r
generate a new RIFF WAV header (any extra RIFF info in original
file will be discarded)
--raw-pcm
intput data is raw pcm (44,100 Hz, 16-bit, 2-channels)
--raw-pcm=sr,bits,chans
intput data is raw pcm with specified sample-rate, bit-depth, and
number of channels (specify 32f for 32-bit floating point data)
-sn
override default hybrid mode noise shaping where n is a float value
between -1.0 and 1.0; negative values move noise lower in freq,
positive values move noise higher in freq, use 0 for no shaping
(white noise)
-t
copy input file's time stamp to output file(s)
--use-dns
force use of dynamic noise shaping (hybrid mode only)
-v
verify output file integrity after write (not for piped output)
--version
write program version to stdout
-w “Field=Value”
write specified text metadata to APEv2 tag
-w “Field=@file.ext”
write specified text metadata from file to APEv2 tag, normally used
for embedded cuesheets and logs (field names “Cuesheet” and “Log”)
--write-binary-tag “Field=@file.ext”
write the specified binary metadata file to APEv2 tag, normally
used for cover art with the specified field name “Cover Art
(Front)”
-x[n]
extra encode processing (optional n = 1 to 6, 1=default), -x1 to
-x3 to choose best of predefined filters, -x4 to -x6 to generate
custom filters (very slow!)
-y
yes to all warnings (use with caution!)
-z
don't set console title to indicate progress (prevents console from
staying "WavPack Completed")
