6 wavpack - encode audio files to wavpack
7
9 wavpack [-options] INFILE... [-o OUTFILE]
10
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.
25 INPUT FILE FORMATS
27 • Microsoft RIFF, extension “.wav”, includes BWF and RF64 variants
28 • WavPack, extension “.wv”, transcode operation, tags copied
30 • Apple Core Audio, extension “.caf”
32 • Sony Wave64, extension “.w64”
34 • Philips DSDIFF, extension “.dff”
36 • Sony DSD Stream, extension “.dsf”
38
40 -a
41 Adobe Audition (CoolEdit) mode for 32-bit floats
42 --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 -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 --blocksize=n
53 specify block size in samples (max = 131072 and min = 16 with
54 --merge-blocks, otherwise 128)
55 -c
57 create correction file (.wvc) for hybrid mode (results in 2-file
58 lossless compression)
59 -cc
61 maximum hybrid compression (hurts lossy quality & decode speed)
62 --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 --cross-decorr
72 use cross-channel correlation in hybrid mode (on by default in
73 lossless mode and with -cc option)
74 -d
76 delete source file if successful (use with caution!)
77 -f
79 fast mode (fast, but some compromise in compression ratio)
80 -g
82 general/normal mode, cancels previously specified -f and -h options
83 -h
85 high quality (better compression ratio, but slightly slower encode
86 and decode than normal mode)
87 -hh
89 very high quality (best compression, but slowest and NOT
90 recommended for use on vintage playback devices)
91 --help
93 display extended help
94 -i
96 ignore length in wav header and allow WAV files greater than 4 GB
97 (note that this will attempt to fix the WAV header stored in the
98 WavPack file, combine with -r to create a fresh header instead)
99 --import-id3
101 import applicable tag items from ID3v2.3 tag present in DSF (and
102 other) files into APEv2 tag (if there are > 1 MB cover images
103 present add --allow-huge-tags to include them, and -r if you do not
104 want large images appearing twice in the WavPack file, although
105 this will remove the entire original ID3v2 tag)
106 -jn
108 joint-stereo override (0 = left/right, 1 = mid/side)
109 -m
111 compute & store MD5 signature of raw audio data
112 --merge-blocks
114 merge consecutive blocks with equal redundancy (used with
115 --blocksize option and is useful for files generated by the
116 lossyWAV program or decoded HDCD files)
117 -n
119 calculate average and peak quantization noise (hybrid only,
120 reference fullscale sine)
121 --no-overwrite
123 never overwrite, nor ask to overwrite, an existing file (this is
124 handy for resuming a cancelled batch operation and obviously cannot
125 be mixed with -y)
126 --no-utf8-convert
128 don't recode passed tags from local encoding to UTF-8, assume they
129 are in UTF-8 already
130 -o OUTFILE
132 specify output filename (only if single source file) or target
133 directory (must exist)
134 --pair-unassigned-chans
136 encode unassigned channels into stereo pairs
137 --pre-quantize=bits
139 pre-quantize samples to bits depth BEFORE encoding and MD5
140 calculation (common use would be --pre-quantize=20 for 24-bit or
141 float material recorded with typical converters)
142 -q
144 quiet (keep console output to a minimum)
145 -r
147 parse headers to determine audio format and length but do not store
148 the headers in the resulting WavPack file (a minimum header will be
149 generated by wvunpack, but some non-audio metadata might be lost)
150 --raw-pcm
152 input data is raw pcm (44,100 Hz, 16-bit, 2-channels)
153 --raw-pcm=sr,bits[f|s|u],chans,[le|be]
155 input data is raw pcm with specified sample-rate, bit-depth
156 (float,unsigned,signed), number of channels, and endianness
157 (defaulted parameters may be omitted, specify bits=1 for DSD)
158 --raw-pcm-skip=begin[,end]
160 skip begin bytes before encoding raw PCM (header) and skip end
161 bytes at the EOF (trailer)
162 -sn
164 override default hybrid mode noise shaping where n is a float value
165 between -1.0 and 1.0; negative values move noise lower in freq,
166 positive values move noise higher in freq, use 0 for no shaping
167 (white noise)
168 -t
170 copy input file's time stamp to output file(s)
171 --use-dns
173 force use of dynamic noise shaping (hybrid mode only)
174 -v
176 verify output file integrity after write (not for piped output)
177 --version
179 write program version to stdout
180 -w Encoder
182 write actual encoder metadata to APEv2 tag (e.g., “Encoder=WavPack
183 5.5.0”)
184 -w Settings
186 write actual user settings metadata to APEv2 tag (e.g.,
187 “Settings=-hb384cx3”)
188 -w “Field=Value”
190 write specified text metadata to APEv2 tag
191 -w “Field=@file.ext”
193 write specified text metadata from file to APEv2 tag, normally used
194 for embedded cuesheets and logs (field names “Cuesheet” and “Log”)
195 --write-binary-tag “Field=@file.ext”
197 write the specified binary metadata file to APEv2 tag, normally
198 used for cover art with the specified field name “Cover Art
199 (Front)”
200 -x[n]
202 extra encode processing (optional n = 0 to 6, 1=default), -x0 for
203 no extra processing, -x1 to -x3 to choose best of predefined
204 filters, -x4 to -x6 to generate custom filters (very slow!)
205 -y
207 yes to all warnings (use with caution!)
208 -z[n]
210 don't set (n = 0 or omitted) or set (n = 1) console title to
211 indicate progress (leaves "WavPack Completed")
212
214 wvunpack(1), wvgain(1), wvtag(1)
