NAME

6       wavpack - encode audio files to wavpack
7

SYNOPSIS

9       wavpack [-options] INFILE... [-o OUTFILE]
10

DESCRIPTION

12       wavpack encodes the specified source file(s) into WavPack files using
13       the options provided. The source files may be any of the file format
14       types listed below, and the audio data may be either uncompressed PCM
15       or DSD (depending on the format). Raw audio may also be specified (see
16       --raw-pcm). The output filename will be source-name.wv unless
17       overridden with the -o switch. Multiple input files may be specified
18       resulting in multiple WavPack files, and in that case -o may be used to
19       specify an alternate target directory.  Stdin and stdout may be
20       specified with “-”. In the case of transcoding from existing WavPack
21       files, all tags are copied (and may be modified with additional args)
22       and unless an alternate name or directory is specified, the source
23       files are safely overwritten. To decode WavPack files back to their
24       original format (or raw audio) use the wvunpack program.

OPTIONS

40       -a
41           Adobe Audition (CoolEdit) mode for 32-bit floats
42
43       --allow-huge-tags
44           allow tag data up to 16 MB (embedding > 1 MB is not recommended for
45           portable devices and may not work with some programs including
46           WavPack pre-4.70)
47
48       -bn
49           enable hybrid compression, n = 2.0 to 23.9 bits/sample, or n =
50           24-9600 kbits/second (kbps), not available with DSD audio
51
52       --blocksize=n
53           specify block size in samples (max = 131072 and min = 16 with
54           --merge-blocks, otherwise 128)
55
56       -c
57           create correction file (.wvc) for hybrid mode (results in 2-file
58           lossless compression)
59
60       -cc
61           maximum hybrid compression (hurts lossy quality & decode speed)
62
63       --channel-order=list
64           specify (comma separated) channel order if not Microsoft standard
65           (which is
66           FL,FR,FC,LFE,BL,BR,FLC,FRC,BC,SL,SR,TC,TFL,TFC,TFR,TBL,TBC,TBR);
67           specify “...”  to indicate that channels are not assigned to
68           specific speakers, or terminate list with “...”  to indicate that
69           any channels beyond those specified are unassigned
70
71       --cross-decorr
72           use cross-channel correlation in hybrid mode (on by default in
73           lossless mode and with -cc option)
74
75       -d
76           delete source file if successful (use with caution!)
77
78       -f
79           fast mode (fast, but some compromise in compression ratio)
80
81       -h
82           high quality (better compression ratio, but slower encode and
83           decode than default mode)
84
85       -hh
86           very high quality (best compression, but slowest and NOT
87           recommended for use on portable playback devices)
88
89       --help
90           display extended help
91
92       -i
93           ignore length in wav header (no pipe output allowed)
94
95       --import-id3
96           import applicable tag items from ID3v2.3 tag present in DSF (and
97           other) files into APEv2 tag (if there are > 1 MB cover images
98           present add --allow-huge-tags to include them, and -r if you do not
99           want large images appearing twice in the WavPack file, although
100           this will remove the entire original ID3v2 tag)
101
102       -jn
103           joint-stereo override (0 = left/right, 1 = mid/side)
104
105       -m
106           compute & store MD5 signature of raw audio data
107
108       --merge-blocks
109           merge consecutive blocks with equal redundancy (used with
110           --blocksize option and is useful for files generated by the
111           lossyWAV program or decoded HDCD files)
112
113       -n
114           calculate average and peak quantization noise (hybrid only,
115           reference fullscale sine)
116
117       --no-utf8-convert
118           don't recode passed tags from local encoding to UTF-8, assume they
119           are in UTF-8 already
120
121       -o OUTFILE
122           specify output filename (only if single source file) or target
123           directory (must exist)
124
125       --pair-unassigned-chans
126           encode unassigned channels into stereo pairs
127
128       --pre-quantize=bits
129           pre-quantize samples to bits depth BEFORE encoding and MD5
130           calculation (common use would be --pre-quantize=20 for 24-bit or
131           float material recorded with typical converters)
132
133       -q
134           quiet (keep console output to a minimum)
135
136       -r
137           remove file headers (file-appropriate headers will be regenerated
138           during unpacking)
139
140       --raw-pcm
141           input data is raw pcm (44,100 Hz, 16-bit, 2-channels)
142
143       --raw-pcm=sr,bits[f|s|u],chans,[le|be]
144           input data is raw pcm with specified sample-rate, bit-depth
145           (float,unsigned,signed), number of channels, and endianness
146           (defaulted parameters may be omitted, specify bits=1 for DSD)
147
148       --raw-pcm-skip=begin[,end]
149           skip begin bytes before encoding raw PCM (header) and skip end
150           bytes at the EOF (trailer)
151
152       -sn
153           override default hybrid mode noise shaping where n is a float value
154           between -1.0 and 1.0; negative values move noise lower in freq,
155           positive values move noise higher in freq, use 0 for no shaping
156           (white noise)
157
158       -t
159           copy input file's time stamp to output file(s)
160
161       --use-dns
162           force use of dynamic noise shaping (hybrid mode only)
163
164       -v

169
170       -w Encoder
171           write actual encoder metadata to APEv2 tag (e.g., “Encoder=WavPack
172           5.0.0”)
173
174       -w Settings
175           write actual user settings metadata to APEv2 tag (e.g.,
176           “Settings=-hb384cx3”)
177
178       -w “Field=Value
179           write specified text metadata to APEv2 tag
180
181       -w “Field=@file.ext
182           write specified text metadata from file to APEv2 tag, normally used
183           for embedded cuesheets and logs (field names “Cuesheet” and “Log”)
184
185       --write-binary-tag “Field=@file.ext
186           write the specified binary metadata file to APEv2 tag, normally
187           used for cover art with the specified field name “Cover Art
188           (Front)”
189
190       -x[n]
191           extra encode processing (optional n = 1 to 6, 1=default), -x1 to
192           -x3 to choose best of predefined filters, -x4 to -x6 to generate
193           custom filters (very slow!)
194
195       -y
196           yes to all warnings (use with caution!)
197
198       -z[n]
199           don't set (n = 0 or omitted) or set (n = 1) console title to
200           indicate progress (leaves "WavPack Completed")
