About meta tagging

To do meta tagging on mp3, WMA files, you need to create a metatagger object.

set meta = CreateObject("AudioCtl.MetaData.1")
'Set the audio file name
meta.AudioFile = "1.mp3"
'Now, you can get or put tag information. The typical ID3 tag set is supported.
msgbox meta.Artist + "|" + meta.Title + "|" + meta.Description + "|" + meta.Album + "|" + meta.Year + "|" + meta.Genre + "|" + CStr(meta.Track)
meta.Description = "Test"
'Update the tag in the file
meta.Update

meta tagging object also supports MP3 album picture tag. See the embedimage.vbs demo for details.
