I am interested in knowing if developers have to pay a license fee ( searched for " mp3 royality rates " on G. ) when using mp3 files inside the game ? There is a strange website where they want 2500 bucks for a game ? Is this true or a hoax ? I know this is not a lawyer forum but i do not want running into trouble. If that would be true what to do ? Only using ogg ? And if yes how ? And what about the .wav format ?
