ACX & Audiobook Platform Requirements
All tools reviewed export MP3/WAV. You'll need Audacity (free) to normalize LUFS and add room tone before ACX submission.
ACX (Audible) Requirements
- MP3 at 192 kbps or higher
- Mono or stereo (mono recommended)
- -23 LUFS average loudness
- -3 dBFS peak
- Room tone (0.5-1 sec) at start and end of each file
- No background noise or music
- Each chapter exported as a separate file
- Disclose AI narration in product description
Other Platforms
Findaway (Draft2Digital)
Similar to ACX — MP3, loudness normalization, chapter files. More lenient on minor variations.
Apple Books
MP3 or AAC, -16 LUFS for streaming. Accepts stereo. Less strict than ACX on room tone.
Direct Sales (Gumroad, Payhip)
No platform requirements — export clean MP3 at 192 kbps and distribute freely.
From Manuscript to Published Audiobook: 6 Steps
The complete production workflow using any AI audiobook tool. Full audiobook guide →
Prepare your manuscript
Remove formatting artifacts, fix proper nouns with phonetic spellings (e.g., 'Aethon' → 'EE-thon').
Choose voices
Select narrator + character voices. 4-8 distinct voices is the sweet spot. Vary gender, accent, and tone clearly.
Add emotion tags
Tag dialogue and emotional moments for Studio+ expressiveness: [excited], [calm], [serious], [whisper].
Generate in chunks
500-1,000 characters per generation for consistency. Longer runs risk prosody drift.
QA each chapter
Listen for mispronunciations, prosody issues, and character voice drift. Fix and regenerate only affected segments.
Export + normalize
Export MP3/WAV, normalize to -23 LUFS with Audacity (free), then upload to ACX or Findaway.
AI Audiobook Cost by Word Count (2026)
AI narration pays for itself in 10-20 audiobook sales. Human narration requires 320-800.
| Word Count | Characters | SG.ai | ElevenLabs | Human Narrator |
|---|---|---|---|---|
| 20,000 (novella) | ~100K | Free tier | Free tier | $750-1,500 |
