Audiobook Chapter Workflow: From Manuscript to Export
Updated September 3, 2026
TL;DR: one Studio project per book, one chapter per heading, one paragraph per re-take. Cast and pronunciation rules once, generate chapter by chapter, review at 1.25×, regenerate only what fails, export per chapter with the Audiobook preset and read the distribution report. Everything below is the order that avoids rework.
The order that avoids rework
- ImportPaste or upload the manuscript; headings become chapters, blank lines become paragraphs. Fix structure now — merging paragraphs later means re-generating them.
- CastAssign the narrator, then character voices for recurring speakers. Assignments persist through the project.
- Pronunciation rulesEnter names and terms before generating anything: an alias respelling works on every voice tier; IPA is available for Leap Turbo voices and pinyin for Leap Natural voices.
- Generate one chapterNot the whole book. Listen, adjust the director's note or the voice, and only then batch the rest.
- Review and re-takeListen at 1.25× with the text open. Regenerate failing paragraphs; earlier takes stay in version history.
- ExportPer chapter or whole book. Standard preset for streaming (-14 LUFS, 48 kHz); Audiobook preset for retailer specs (44.1 kHz, -20 LUFS mastering start, then RMS/peak/bitrate/duration checks on the final MP3). Subtitles and an optional music bed export with it.
Chapter conventions that pay off
- Name chapters exactly as the retailer will list them; export filenames follow.
- Keep front matter as its own chapter so the opening credits export as one file.
- Split any chapter over ~100 minutes; the distribution checks flag files over 120.
- Put recurring asides (recaps, epigraphs) in their own paragraphs so a change is one re-take.
Reading the distribution report
With the Audiobook preset, each export is measured after encoding: RMS between −23 and −18 dBFS, peak at or below −3 dB, 44.1 kHz, at least 192 kbps CBR, file under 120 minutes; noise floor is reported as an estimate only. A pass means the file meets the common technical spec. It does not mean a given retailer accepts AI narration — the report says so — so check policy before you upload.
Narrators to audition
Frequently asked questions
Whole-book or per-chapter export?
Per chapter for retailers (they want separate files and the checks enforce a 120-minute cap); whole-book for a single podcast-style release or a proof listen.
What's the difference between the Standard and Audiobook presets?
Standard masters to -14 LUFS / 48 kHz for streaming video and podcasts. Audiobook masters to a -20 LUFS starting point at 44.1 kHz with a lower true-peak ceiling and then runs distribution checks on the encoded file.
Can I change the narrator halfway?
Yes, but regenerate the earlier chapters too; voice changes mid-book are the most common listener complaint.
Do subtitles export with chapters?
Yes — SRT/VTT per chapter, generated from the narration timeline (Creator and above).
