A .NET library for reading and writing FLAC metadata.
PM> Install-Package FlacLibSharp
Or go to the nuget page: https://www.nuget.org/packages/FlacLibSharp
If you use this for anything important, make sure your files are backed up. Since this was a hobby project I cannot guarantee anything in terms of quality.
Please evaluate carefully and report any issues you find here on GitHub.
using (FlacFile file = new FlacFile(@"Data\testfile1.flac"))
{
// Access to the StreamInfo class (actually this should ALWAYS be there ...)
var streamInfo = file.StreamInfo;
if (streamInfo != null) {
Console.WriteLine("Flac audio length in seconds: {0}", streamInfo.Duration);
}
// Access to the VorbisComment IF it exists in the file
var vorbisComment = file.VorbisComment;
if (vorbisComment != null) {
Console.WriteLine("Artist - Title: {0} - {1}", vorbisComment.Artist.Value, vorbisComment.Title.Value);
}
// Access to the VorbisComment IF it exists in the file, with multiple values for a single field
var vorbisComment = file.VorbisComment;
if (vorbisComment != null) {
foreach(var value in vorbisComment.Artist) {
Console.WriteLine("Artist: {0}", value);
}
}
// Get all other types of metdata blocks:
var metadata = file.Metadata;
foreach (MetadataBlock block in metadata) {
Console.WriteLine("{0} metadata block.", block.Header.Type);
}
}Modify a vorbis comment, create a vorbis block if none exists:
using (FlacFile flac = new FlacFile("example.flac"))
{
// First get the existing VorbisComment (if any)
var comment = flac.VorbisComment;
if (comment == null)
{
// Create a new vorbis comment metadata block
comment = new VorbisComment();
// Add it to the flac file
flac.Metadata.Add(comment);
}
// Update the fields
comment.Artist.Value = "Aaron";
comment.Title.Value = "Hello World";
// Write the changes back to the FLAC file
flac.Save();
