ID3 Support

[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

ID3 is an organization that has defined a set of standards for including metadata in MPEG Layer-3 (MP3) audio files. The objects of the Windows Media Format SDK provide support for ID3 compatible attributes. Three distinct ID3 versions are supported: ID3v1.x, ID3v2.2, and ID3v2.3/v2,4. For a list of the attributes that equate to ID3 frames, see ID3 Tag Support.

Unless otherwise noted, no validation of ID3 frame data is performed by the objects of this SDK. For example, the metadata attribute WM/Lyrics_Synchronised stores the song lyrics with corresponding time stamps. When writing a WM/Lyrics_Synchronised attribute, the objects of this SDK will not check to ensure that the time stamps are in chronological order or perform validation of any kind.
