If it were me I wouldn't make anything from scratch. I would download an existing audio bible that's known to work.
Then all that would be needed is to swap out the audio from the existing files, and renaming the master folder to your own custom name.
Everything else is already designed to work as is. You can record your own audio files then when 'saving-as', right click on the existing name so it applies it to the filename box, then overwrite it. So you don't even have to match the names, it does it for you.
As in, if the filename of the audio clip you are overwriting is 01Gen004 (Genesis chapter 4), just right click on the existing name and 01Gen004 will be applied to the save filename, then overwrite it when saving. That way you know for sure Sword Searcher can read it, and you didn't have any typos.
