after using calibe with splitepub plugin it'll output an epub for each chapter. Copy that directory with subdirectories which contain the chapter01.epub, chapter02.epub, etc. and run this command. It'll output nicely formatted text chapters that are easily to clean up. Then just batch run edge-tts to make an opus chaptered audiobook.
