Announcing TagLibSharp2 - MIT-licensed alternative

[decriptor]

Hi all,

I wanted to share that I've released TagLibSharp2, a new MIT-licensed library for reading and writing audio metadata in .NET.

Why a new library?

TagLib# has served the community well for many years, but some projects need:

• MIT licensing instead of LGPL
• Async I/O for high-throughput scenarios
• Modern .NET features like nullable reference types and Span<T>
• Result-based error handling instead of exceptions

What's supported in v0.1.0

• MP3 (ID3v1 and ID3v2.3/2.4)
• FLAC
• Ogg Vorbis
• Extended metadata: ReplayGain, MusicBrainz IDs, album art, and more

Clean-room implementation

TagLibSharp2 was built from format specifications (id3.org, xiph.org), not from TagLib# source code. This ensures clean IP separation while maintaining compatibility with the same file formats.

• NuGet: https://www.nuget.org/packages/TagLibSharp2
• Migration Guide: https://github.com/decriptor/TagLibSharp2/blob/main/docs/MIGRATION-FROM-TAGLIB.md

This isn't meant to replace TagLib# - it's an alternative for those who need different licensing or modern .NET features. TagLib# still supports many more formats (MP4, ASF, APE, etc.) that TagLibSharp2 doesn't yet cover.

Feedback and contributions welcome!
