hey man thanks for taking the time to make a comment!

Just to clarify, MonoBox is still in development, and all comments and feedback from people like you, who take interest in my project, are recorded and added to my ever-growing to-do list haha 😁

Regarding your question - MonoBox does not yet support flac files at this stage, but only mp3 files, although I am aware of the high demand for flac support, so this is high on my priority list.

Also, I'd appreciate it greatly if you could star the repo! ⭐
