wavpack: encode wav files to wavpack

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

-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)

--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!)
