NAME¶
wavpack - encode wav files to wavpackSYNOPSIS¶
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¶
-aAdobe 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")
