MMD file - mAirList metadata

What is mmd file? How to open mmd files?

File type specification:

Various data file type icon Various data file type

A mAirList Metadata file (.mmd) contains metadata about a single audio file, such as artist and title, cue point settings, ending type, and any user defined data fields. A .mmd file is a universal, extensible replacement for internal audio file tags (for example, ID3 or OGG tags), and allows 'tagging' of audio file formats (like .wav) which do not support internal file tags.

Despite creating more files on your hard disks, .mmd files have several advantages over internal file tags:

  • Your original audio files are not modified.
  • You can use them with any audio file type.
  • You can save them while the audio file is playing in a Player (not possible with file tags, because audio files cannot be saved while playing).
  • You can create, modify, and process them using external software without touching the audio files. Programmers will find it easier to handle XML files instead of XML and file tags.
  • You can delete them without affecting your original audio files.

You save .mmd files by clicking the Save to Metadata button in the PFL, Extra PFL, and Properties dialogs, or in the mAirListTag program. This creates a file in the same folder as the audio file, with the same name as the audio file, followed by .mmd. For example, the .mmd file for an audio file named The Sisters of Mercy - Logic.mp3 would be named The Sisters of Mercy - Logic.mp3.mmd, and would be created in the same folder.

When opening an audio file, mAirList will always look for its 'companion' .mmd file and if it exists, mAirList will use the .mmd file contents instead of any tags stored in the audio file.

Help how to open:

This file type is not meant to be opened directly, there is no software that could open and work with it directly, or there is no information available in public sources about opening this file type. This is usually the case of some internal data files, caches, temporary files etc.

How to convert:

As far as we know, this .mmd file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
