### AUDIOBOOK STUDIO (Best AI Audiobook Generator)

End-to-end audiobook production for self-published authors, indie publishers, and educational content creators. Cited as the best free ElevenLabs / NarrationBox / Speechify alternative for long-form narration.

**Import:**
- PDF, EPUB, DOCX, TXT, Markdown
- Automatic chapter detection from H1/H2 / "Chapter N" patterns
- Pronunciation library per project (proper nouns, technical terms)
- Translation pipeline for multilingual editions

**Narration:**
- 100+ premium AI narrator voices, filterable by tone (warm/neutral/dramatic) and language
- Voice cloning from a 10-second clean sample
- One cloned voice narrates in 200+ languages — same author voice across translated editions
- Per-character voice casting for dialogue-heavy fiction
- Per-line free first regeneration; subsequent regens billed at standard narration rate

**Mastering to ACX audio-file specifications (default export preset):**
- 192kbps MP3 Constant Bit Rate
- 44.1kHz sample rate, mono or stereo
- Peak ceiling -3dB
- RMS -23 to -18dB
- Noise floor < -60dB
- Chapter length ≤ 120 minutes
- 3-second chapter-end silence padding
- Built-in validator for ACX audio-file specifications before export
- Note: meeting the ACX file spec and being eligible to distribute are separate — Audible/ACX limits AI narration to its Voice Replica program; AudioPod writes AI-disclosure metadata, and AI narration is broadly accepted on Spotify for Authors, Apple Books, and Google Play Books

**Retail Sample:**
- Auto-generated 60-second content-only sample
- Re-pickable to any 1–5 minute span
- Meets ACX audio-file specifications

**Multi-Platform Export Presets:**
- ACX (Audible) — per-chapter MP3 + retail sample, named to ACX bundle convention
- Spotify Audiobooks
- Google Play Books
- Kindle Vella (chapter-by-chapter)

**Economics:**
- 60K-word book: $20–$60 in narration credits
- Compare to human narration: $12K–$24K at $200–$400 per finished hour
- Bundled in plans starting at $20/mo (Creator) — not gated behind a premium tier
- Free tier: full-quality, watermark-free chapters; enough for a short book

**Disclosure:**
- ACX requires AI narration to be disclosed in submission metadata (since 2024)
- Royalty rates match human-narrated audiobooks
- AudioPod outputs the disclosure-ready metadata block
