Good afternoon or whatever time is it in the country reader.

I've been playing for quite a long time LFS and I've recently been doing stuff with the archives and all of that. But i found out that the engine archives are not normal ones like ogg or mp3, etc. My question is, Is it possible to convert that archives into mp3 or another more normal archive?? Or is there any way I could do some audio in mp3 and convert it into .eng?

Thank you for reading c:
