file extension MMD

File extension MMD description:

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.
