|
.SH NAME
|
|
metaflac \- program to list, add, remove, or edit metadata in one or more FLAC files.
|
|
.SH SYNOPSIS
|
|
|
|
\fBmetaflac\fR [ \fB\fIoptions\fB\fR ] [ \fB\fIoperations\fB\fR ] \fB\fIFLACfile\fB\fR\fI ...\fR
|
|
|
|
.SH "DESCRIPTION"
|
|
.PP
|
|
Use \fBmetaflac\fR to list, add, remove, or edit
|
|
metadata in one or more FLAC files. You may perform one major operation,
|
|
or many shorthand operations at a time.
|
|
.SH "OPTIONS"
|
|
.TP
|
|
\fB--preserve-modtime\fR
|
|
Preserve the original modification time in spite of edits.
|
|
.TP
|
|
\fB--with-filename\fR
|
|
Prefix each output line with the FLAC file name (the default if
|
|
more than one FLAC file is specified).
|
|
.TP
|
|
\fB--no-filename\fR
|
|
Do not prefix each output line with the FLAC file name (the default
|
|
if only one FLAC file is specified).
|
|
.TP
|
|
\fB--dont-use-padding\fR
|
|
By default metaflac tries to use padding where possible to avoid
|
|
rewriting the entire file if the metadata size changes. Use this
|
|
option to tell metaflac to not take advantage of padding this way.
|
|

.TP
|

Vorbis comment spec, of the form "NAME=VALUE". If there is
|
|
currently no tag block, one will be created.
|
|
.TP
|
|
\fB--import-tags-from=file\fR
|
|
Import tags from a file. Use '-' for stdin. Each
|
|
line should be of the form NAME=VALUE. Multi-line comments
|
|
are currently not supported. Specify --remove-all-tags and/or
|
|
--no-utf8-convert before --import-tags-from if necessary.
|
|
.TP
|
|
\fB--export-tags-to=file\fR
|
|
Export tags to a file. Use '-' for stdin. Each
|
|
line will be of the form NAME=VALUE. Specify
|
|
--no-utf8-convert if necessary.
|
|
.TP
|
|
\fB--import-cuesheet-from=file\fR
|
|
Import a cuesheet from a file. Only one FLAC file may be
|
|
specified. A seekpoint will be added for each index point in
|
|
the cuesheet to the SEEKTABLE unless --no-cued-seekpoints is
|
|
specified.
|
|
.TP
|
|
\fB--export-cuesheet-to=file\fR
|
|
Export CUESHEET block to a cuesheet file, suitable for use by
|
|
CD authoring software. Use '-' for stdin. Only one FLAC file
|
|
may be specified on the command line.
|
|
.TP
|
|
\fB--add-replay-gain\fR
|
|
Calculates the title and album gains/peaks of the given FLAC
|
|
files as if all the files were part of one album, then stores
|
|
them in the VORBIS_COMMENT block. The tags are the same as
|
|
those used by vorbisgain. Existing ReplayGain tags will be
|
|
replaced. If only one FLAC file is given, the album and title
|
|
gains will be the same. Since this operation requires two
|
|
passes, it is always executed last, after all other operations
|
|
have been completed and written to disk. All FLAC files
|
|
specified must have the same resolution, sample rate, and
|
|
number of channels. The sample rate must be one of 8, 11.025,
|
|
12, 16, 22.05, 24, 32, 44.1, or 48 kHz.
|
|
.TP
|
|
\fB--add-seekpoint={\fI#\fB|\fIX\fB|\fI#x\fB|\fI#s\fB}\fR
|
|
Add seek points to a SEEKTABLE block. Using #, a seek point at
|
|
that sample number is added. Using X, a placeholder point is
|
|
added at the end of a the table. Using #x, # evenly spaced seek
|
|
points will be added, the first being at sample 0. Using #s, a
|
|
seekpoint will be added every # seconds (# does not have to be a
|
|
whole number; it can be, for example, 9.5, meaning a seekpoint
|
|
every 9.5 seconds). If no SEEKTABLE block exists, one will be
|
|
created. If one already exists, points will be added to the
|
|
existing table, and any duplicates will be turned into placeholder
|
|
points. You may use many --add-seekpoint options; the resulting
|
|
SEEKTABLE will be the unique-ified union of all such values.
|
|
Example: --add-seekpoint=100x --add-seekpoint=3.5s will add 100
|
|
evenly spaced seekpoints and a seekpoint every 3.5 seconds.
|
|
.TP
|
|
\fB--add-padding=length\fR
|
|
Add a padding block of the given length (in bytes). The overall
|
|
length of the new block will be 4 + length; the extra 4 bytes is
|
|
for the metadata block header.
|

\fB--list\fR
|
|
List the contents of one or more metadata blocks to stdout. By
|
|
default, all metadata blocks are listed in text format. Use the
|
|
following options to change this behavior:
|
|
.RS
|
|
.TP
|
|
\fB--block-number=#[,#[...]]\fR
|
|
An optional comma-separated list of block numbers to display.
|
|
The first block, the STREAMINFO block, is block 0.
|
|
.TP
|
|
\fB--block-type=type[,type[...]]\fR
|
|
.TP
|
|
\fB--except-block-type=type[,type[...]]\fR
|
|
An optional comma-separated list of block types to included
|
|
or ignored with this option. Use only one of --block-type or
|
|
--except-block-type. The valid block types are: STREAMINFO,
|
|
PADDING, APPLICATION, SEEKTABLE, VORBIS_COMMENT. You may
|
|
narrow down the types of APPLICATION blocks displayed as
|
|
follows:
|
|
|
|
APPLICATION:abcd The APPLICATION block(s) whose textual repre-
|
|
sentation of the 4-byte ID is "abcd"
|
|
APPLICATION:0xXXXXXXXX The APPLICATION block(s) whose hexadecimal big-
|
|
endian representation of the 4-byte ID is
|
|
"0xXXXXXXXX". For the example "abcd" above the
|
|
hexadecimal equivalalent is 0x61626364

.TP
|

\fB--application-data-format=hexdump|text\fR
|
|
If the application block you are displaying contains binary
|
|
data but your --data-format=text, you can display a hex dump
|
|
of the application data contents instead using
|
|
--application-data-format=hexdump.

.TP
|
|
\fB--remove\fR
|
|
Remove one or more metadata blocks from the metadata. Unless
|
|
--dont-use-padding is specified, the blocks will be replaced with
|
|
padding. You may not remove the STREAMINFO block.
