Originally written 30 April 2021 in Notepad (while my internet was slow due to uploading a file to Archive.org): Something that might help future me when it comes to creating an M4B file.
So, when you're exporting as an MP3, you get to choose from a whole list of different kbps compression values, which affects the final file size that someone will download. If you let Archive.org compress an uploaded WAV, it uses 128 kbps, which is often held to be too high for podfic beyond a few minutes, so I usually export my own MP3 file to upload to Archive.org at 96 kbps. Of note, I also haven't uploaded anything longer than about 55 minutes before (and I usually don't have SFX to worry about).
I have no idea how often I'll do fic of the length as "Come Undone", but 96 kbps is a smidge too high when trying to work with the entire work. I know it's nearly 7 hours, and there's only so much compression I can do, but I used 64 kbps for the MP3 files used to make the M4B in AudioBook Converter (uploaded to Google Drive for downloading purposes on my Windows laptop). For future fic, I may want to keep that in mind as I go, so I don't have to re-export and re-download at the end.
