Step-by-step guide
How to Use Audiobook Chapter Splitter
Start for free — no credit card, no software to install.
Upload the full manuscript
Add the whole book as EPUB, DOCX, TXT or a text-based PDF; the analysis splits it into chapters automatically.
Generate across the book
Run generation over every chapter, or pick a working subset first to check pacing.
Switch to per-chapter export
Once a book passes roughly 8,000 segments, export moves from one combined file to individual chapter downloads.
Download each file separately
Each chapter arrives as its own MP3 or WAV, still numbered in reading order.

About this tool
Everything you need to know about Audiobook Chapter Splitter
An audiobook chapter splitter breaks a long manuscript's finished narration into individual chapter files instead of one continuous track. Past roughly 8,000 generated segments a book switches to exporting chapter by chapter rather than as a single file, and working in separate files also means re-rendering one section after a fix without touching the rest of the book.

FAQ
Audiobook Chapter Splitter — FAQ
Common questions users ask about the Audiobook Chapter Splitter voice. If you need additional help, please contact us via the contact form or email us at support@vocallab.ai.
Why did my export switch to separate chapter files?
Once a book's audio passes roughly 8,000 generated segments, the export moves from one combined file to individual chapter downloads automatically.
Can I still get one combined audiobook file for a shorter book?
Yes, books under that segment count export as a single continuous MP3 or WAV plus one combined SRT.
Do the split files keep the same voice and settings?
Yes, every chapter file uses the same cast, model and export settings as the rest of the book.
Can I re-download just one chapter after fixing a typo?
Yes, regenerate the corrected chapter and export just that file without touching the others.
Is there a limit to how many chapter files one book can produce?
No fixed limit — a manuscript with dozens of chapters exports the same number of individual files.
