Editing MP3 Music Metadata

You’ve probably heard a lot about metadata. Metadata is “hidden” data in computer files that “tags” a file with certain identifying information.

For example, you may have heard the word used in discussions in the media about metadata associated with digital recordings of phone conversations. Metadata formats are different for different types of files.

Music Metadata And MP3s

Music metadata can be associated with music files in two different ways: it can be included in the file itself (mp3 or WMA files) or it can be found in a separate file associated with the track on a CD (wav files). An mp3 file is smaller in size and not as high quality audio file as a wav file. Production CDs are created using master wav files. The metadata on a physical CD is placed there by whomever produces, engineers, or masters your CD.

Unless you are the engineer, you will probably not create or edit the metadata associated with the wav files on a CD. (When you rip a CD to your computer using iTunes or some other tool, it knows how to copy the metadata with the wav file and put it in the right place in an mp3file when you convert it).
