The first bad news is that it's the UnityFS format that is, as far as I know, currently not supported by the tools (or partially supported)
The good news is that all the audio there is just FMOD FSB
but it's not an unique archive, there are many inside that mab file.
The second bad news is that the audio is encoded with ogg which can't be extracted as-is with fsbext because it's not playable.
For FSB archives containing ogg data I suggest ever to use this tool:viewtopic.php?f=17&t=1901
But it doesn't have an FSB scanning feature like fsbext, so it's not possible to use it on that mab file.
@id-daemon, can you add this scanning feature to your tool?
