Export audiobook (MP3)
Render this book — or a single chapter — to an MP3 with your current neural voice and speed. Chapter markers are included as a sidecar file. Everything is generated on your device; nothing is uploaded. Long books take a while (audio is synthesized up front), so keep this screen open while it works.
Tip: for audiobook apps, the exported file includes chapter markers derived from the book's sections.
