MLM stands for Music Library Maintainer, and is a collection of small utilities itended to, as its name implies, maintain a music library. It does so by reading and writting a subset of Id3v2.4.0 tags, hencefort refered as the "standard tags".
The standard tags are:
- Artist (
TPE1) - Title (
TIT2) - Album (
TALB) - Album band (
TPE2), usually called "Album artist" in other suites - Year (
TDRC) - Track (
TRCK), including the total number of tracks on the disc - Disc number (
TPOS) - Genre (
TCON), the standard 148 genres from Id3v1 - Comment (
COMM) - Composer (
TCOM) - Original artist (
TOPE) - Album and artist picture (
APIC)
The utilities are:
-
mlm-gui: A GNOME 3 program to edit standard tags, and perhaps playing or reencoding the file containing them. -
mlm-arranger: Command line tool to arrange an MP3 file in a standard hierarchical location. -
mlm-analyze: Command line tool to analyze all the Id3v2.4.0 tags (not only the standard ones) in an MP3 file. -
mlm-copy-tags: Command line tool to copy the standard tags from an MP3 file to another. -
mlm-tags: Command line tool to modify or print the standard tags of a file or group of files. -
mlm-verify: Command line tool to verify that an MP3 file follows the MLM standard.
All the command line utilities accept a --help argument that explains how to
use it, and include man pages.
