NTagLib

NTagLib is a 64 bits C++/CLI library for tagging audio files with TagLib in managed code.

NTagLib requires the Visual C++ 2022 runtime (x64).

This library has been designed to be used with my tags editor, Metatogger.

Here is a screenshot of that software:

Feel free to fork the code and contribute to NTagLib.

How to use the tagging API in C♯

using NTagLib;

// supports the following audio formats: MP3 (*.mp3), FLAC (*.flac), Opus (*.opus), Ogg Vorbis (*.ogg), WMA (*.wma) and AAC/ALAC (*.m4a)
var tagger = new TaglibTagger(@"C:\MyFolder\MyAudioFile.flac");

// getting technical informations

string codecName = tagger.Codec; // "FLAC"
string codecVersion = tagger.CodecVersion; // "1.2.1"
int channelsCount = tagger.Channels; // 2
TimeSpan duration = tagger.Duration; // 0:05:23
int sampleRateInHertz = tagger.SampleRate; // 44100
int bitsPerSample = tagger.BitsPerSample; // 16

// getting or setting textual tags

// textual tags is stored in a dictionary where the key is the tag name in uppercase
Dictionary<string, List<string>> tagsRepository = tagger.Tags;
string? artist = tagger.GetTagValues(TagNameKey.Artist).FirstOrDefault();
tagger.AddTag(TagNameKey.Artist, "Artist 2", "Artist 3");
tagger.ReplaceTag(TagNameKey.Title, "All You Need Is Love");
tagger.RemoveTag(TagNameKey.Comment);
tagger.AddTag("MY_KEY_NAME", "Custom Tag Value");

// getting or setting embedded covers

List<Picture> pictures = tagger.Pictures;
if (pictures.Count != 0)
{
   Picture? mainPicture = pictures.FirstOrDefault(p => p.PictureType == PictureTypes.FrontCover);
   if (mainPicture == null) mainPicture = pictures[0];

   byte[] data = mainPicture.Data;
   string pictureMime = mainPicture.MimeType; // "image/jpeg"
}

pictures.Clear();

byte[] bytes = File.ReadAllBytes(@"C:\MyFolder\MyCover.jpg");
pictures.Add(new Picture(bytes, MimeTypes.JPEG, PictureTypes.FrontCover, String.Empty));

tagger.Save(); // save changes
