We no longer need to use FMOD for anything relating to *.fsb Audio Formats.
Download The Latest Version Python from the Official Website: https://www.python.org/downloads/
First what you need todo, is Download the Latest Release of CATool Here: https://github.com/Minecraft-3DS-Community/CombinedAudioTool
Extract the Downloaded *.zip File.
After Opening the Folder that you Extract the Contents of the *.zip too, Hold the shift Key and Right Click. Then Click "Open Powershell Window Here".
Make sure you Opened Powershell in the Same Directory as CATool.py.
Type your first command, let's get too know all the Commands. Type: python CATool.py help.
This will list all the commands you can type in order do stuff with the Audio Files.
We first are going to Extract all *.fsb Audio Files from the CombinedAudio.bin File.
Find the Directory of CombinedAudio.bin Archive File and use the Command you found in Step No. 6.
Note:
When you invoke the help command, you will see text surrounded by: These Brackets -> [].
Do not include those when you give the path, only have the String in Quotation Marks as such (Example): python CATool.py --eca "C:\Users\batch_893 2283\Downloads\CATool\CombinedAudio.bin".
That will extract the Combined Audio file in that Directory.
