Tag your music

.NET Core ID3 Tagging Library

Extracting album art from FLAC, ID3v2, etc. meta data.

Various ID3 tag–related operations on local audio files

Convert ID3 tags in MP3 files(but not only) from ANSI to unicode format

Originally written in C#, this library will allow you to read MPEG based audio tags (ID3v1 and ID3v2 tags primarily supported) into your .NET application.

Mass update MP3 ID3 tags with the oldest year for each given song. This is useful for compilations of songs that were individually released previously in various different years. Setting the year to the original release year makes it easier to organize and find music by year or decade. The release year is looked up from the MusicBrainz API.

Get and set ID3 tags via CMD.
