ValueError: 16 is not a valid SoundFormat

I am unable to convert FSB version 5 files.

Command:

python3 extract.py file.fsb

Error Message:

I'm having the exact same issue and had to hard code 16 as a dummy format to suppress the exception.

16 is FADPCM format, it's not new but haven't found a lot of support in external tools. I'm not sure whether this library is still maintained but I see some other in progress work for reference: https://github.com/SamboyCoding/Fmod5Sharp/issues/7

Update: I found a working implementation in vgmstream https://github.com/vgmstream/vgmstream/blob/master/src/coding/fadpcm_decoder.c#L17
