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!) SEE ALSO wvunpack(1), wvgain(1) Please visit www.wavpack.com for more information COPYRIGHT This manual page was written by Sebastian Dröge
