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), not available with DSD audio

--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,FLC,FRC,BC,SL,SR,TC,TFL,TFC,TFR,TBL,TBC,TBR); specify lq...rq to indicate that channels are not assigned to specific speakers, or terminate list with lq...rq to indicate that any channels beyond those specified are unassigned

--cross-decorr

use cross-channel correlation in hybrid mode (on by default in lossless mode and with -cc option)

-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)

--import-id3

import applicable tag items from ID3v2.3 tag present in DSF files into APEv2 tag (if there are > 1 MB cover images present add --allow-huge-tags to include them, and -r if you do not want large images appearing twice in the WavPack file, although this will remove the entire ID3 tag wrapper)

-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)

--pair-unassigned-chans

encode unassigned channels into stereo pairs

--pre-quantize=bits

pre-quantize samples to bits depth BEFORE encoding and MD5 calculation (common use would be --pre-quantize=20 for 24-bit or float material recorded with typical converters)

-q

quiet (keep console output to a minimum)

-r

remove file headers (file-appropriate headers will be regenerated during unpacking)

--raw-pcm

input data is raw pcm (44,100 Hz, 16-bit, 2-channels)

--raw-pcm=sr,bits[f|s|u],chans,[le|be]

input data is raw pcm with specified sample-rate, bit-depth (float,unsigned,signed), number of channels, and endianness (defaulted parameters may be omitted, specify bits=1 for DSD)

--raw-pcm-skip=begin[,end]

skip begin bytes before encoding raw PCM (header) and skip end bytes at the EOF (trailer)

-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 Encoder

write actual encoder metadata to APEv2 tag (e.g., lqEncoder=WavPack 5.0.0rq)

-w Settings

write actual user settings metadata to APEv2 tag (e.g., lqSettings=-hb384cx3rq)

-w lqField=Valuerq

write specified text metadata to APEv2 tag

-w lqField=@file.extrq

write specified text metadata from file to APEv2 tag, normally used for embedded cuesheets and logs (field names lqCuesheetrq and lqLogrq)

--write-binary-tag lqField=@file.extrq

write the specified binary metadata file to APEv2 tag, normally used for cover art with the specified field name lqCover Art (Front)rq

-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[n]

don't set (n = 0 or omitted) or set (n = 1) console title to indicate progress (leaves "WavPack Completed")
