I'm new at this whole thing, but I want to convert a .celt file into an MP3. The whole reason for doing this is because of a game I am playing. It has sound files that are stored inside of an .fsb file (This part doesn't matter to much because I already got them separated). In that .fsb file there are .celt files and from what I understand those are the actual sounds from the game. I need a simple way to convert those to a .mp3. Now I've read another post on here that says that they are now under Opus... I have no idea what that means, I searched it and came up with some .exe files that I have no idea how to use. So if some one can please give me a tutorial on how to convert a .celt file to a .mp3 file in simple English that would be amazing.

It might be possible to compare it to a CELT file made by one version of the CELT encoder using a hex editor. Very quickly I took a look at it in Notepad, which often reveals if there's a text signature (like OPUSHEAD in an Ogg Opus file) and didn't see anything. Frankly I'm unmotivated to do any more. They needn't have stuck to regular CELT as it's open source and patent free, and could have modified it anyway. Their software will know how to decode it, regardless of whether it's well-formed for a regular CELT encoder. I note that Mumble uses CELT internally and is used for in-game communications between players and the like. It is upgrading to OPUS, but might still support CELT. It's quite possible a game would base its audio around CELT for that sort of reason - compatibility with low-delay real time chat and high quality stored audio too in a single format.

Maybe this gives you some more leads to try, depending how motivated you are to keep playing around, assuming you're allowed to do so.
