NAME
wavpack - encode wav files to wavpack
SYNOPSIS
wavpack [-options] INFILE... [-o OUTFILE]
DESCRIPTION
wavpack encodes wav files containing uncompressed audio (or raw PCM
data) into WavPack files using the options provided. 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 “-”. To decode
WavPack files back to wav or raw PCM use the wvunpack program.
OPTIONS
-a
Adobe Audition (CoolEdit) mode for 32-bit floats
-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
--pair-unassigned-chans
encode unassigned channels into stereo pairs
-p
practical float storage (also 32-bit ints, not lossless)
-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)
-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!)
