HI @Simpath thanx for your suggestion. I already had this in my mind about writing metadata on audio files but there are some problems with writing metadata right now in some device so currently I am searching for more robust way to write metadata in all device since it is cross platform. And I am also open to and PRs.

Maybe taglib supports that? https://taglib.org/
LGPL license and mpl?

Thanx @tenzap , I was just looking at this lib and found out that they also have ffi for this but only tested on macOS. We should check this lib for cross platform Android/Linux/Windows. If that works, then we will include it in this project.
