cannam@86 61 <br />
cannam@86 62 <span class="commandname">metaflac</span> is the command-line <span class="code">.flac</span> file metadata editor. You can use it to list the contents of metadata blocks, edit, delete or insert blocks, and manage padding.<br />
cannam@86 63 <br />
cannam@86 64 <span class="commandname">metaflac</span> takes a set of "options" (though some are not optional) and a set of FLAC files to operate on. There are three kinds of "options":
cannam@86 65 <ul>
cannam@86 66 <li>
cannam@86 67 Major operations, which specify a mode of operation like listing blocks, removing blocks, etc. These will have sub-operations describing exactly what is to be done.
cannam@86 68 </li>
cannam@86 69 <li>
cannam@86 70 Shorthand operations, which are convenient synonyms for major operations. For example, there is a shorthand operation <span class="argument">--show-sample-rate</span> that shows just the sample rate field from the <span class="code">STREAMINFO</span> metadata block.
cannam@86 71 </li>
cannam@86 72 <li>
cannam@86 73 Global options, which affect all the operations.
cannam@86 74 </li>
cannam@86 75 </ul>
cannam@86 76 All of these are described in the tables below. At least one shorthand or major operation must be supplied. You can use multiple shorthand operations to do more than one thing to a file or set of files. Most of the common things to do to metadata have shorthand operations. As an example, here is how to show the MD5 signatures for a set of three FLAC files:<br />
cannam@86 77 <br />
cannam@86 78 <span class="code">metaflac --show-md5sum file1.flac file2.flac file3.flac</span><br />
cannam@86 79 <br />
cannam@86 80 Another example; this removes all DESCRIPTION and COMMENT tags in a set of FLAC files, and uses the <span class="argument">--preserve-modtime</span> global option to keep the FLAC file modification times the same (usually when files are edited the modification time is set to the current time):<br />
cannam@86 81 <br />
cannam@86 82 <span class="code">metaflac --preserve-modtime --remove-tag=DESCRIPTION --remove-tag=COMMENT file1.flac file2.flac file3.flac</span><br />

The tags are the same as those used by <span class="commandname">vorbisgain</span>. 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.
