NAME

wavpack - encode audio 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 any of the file format types listed below, and the audio data may be either uncompressedPCMorDSD(depending on the format). Raw audio may also be specified (see--raw-pcm). The output filename will besource-name.wvunless overridden with the-oswitch. Multiple input files may be specified resulting in multiple WavPack files, and in that case-omay be used to specify an alternate target directory.Stdinandstdoutmay be specified withlq-rq. 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 their original format (or raw audio) use thewvunpackprogram. 

INPUT FILE FORMATS

*Microsoft RIFF, extensionlq.wavrq, includesBWFandRF64varients

*WavPack, extensionlq.wvrq, trancode operation, tags copied

*Apple Core Audio, extensionlq.cafrq

*Sony Wave64, extensionlq.w64rq

*PhilipsDSDIFF, extensionlq.dffrq

*SonyDSDStream, extensionlq.dsfrq
 

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, orn= 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); specifylq...rqto indicate that channels are not assigned to specific speakers, or terminate list withlq...rqto 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-ccoption)

-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-tagsto include them, and-rif 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--blocksizeoption 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 tobitsdepth BEFORE encoding and MD5 calculation (common use would be--pre-quantize=20for 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, specifybits=1 forDSD)

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

skipbeginbytes before encoding rawPCM(header) and skipendbytes at theEOF(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 tostdout

-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 nameslqCuesheetrqandlqLogrq)

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

write the specified binary metadata file to APEv2 tag, normally used for cover art with the specified field namelqCover 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")
