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

  1. ImportPaste or upload the manuscript; headings become chapters, blank lines become paragraphs. Fix structure now — merging paragraphs later means re-generating them.
  2. CastAssign the narrator, then character voices for recurring speakers. Assignments persist through the project.
  3. 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.
  4. Generate one chapterNot the whole book. Listen, adjust the director's note or the voice, and only then batch the rest.
  5. Review and re-takeListen at 1.25× with the text open. Regenerate failing paragraphs; earlier takes stay in version history.
  6. 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

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).
