Can’t find anything to export the audio to any format, not even vorbis.
FMOD Studio is designed to create audio behavior that is built banks that are then loaded into the FMOD Engine to be played in real time - it is not a DAW, and as a result cannot be used to export audio. If you do need to make modifications to or export audio, I would recommend using your DAW of choice to do so.
I have a daw, and use it regularly. However, I use the panner in this application as it is quite good.
