Step 01 · 1 hr planning
Choose or create your audiobook content
The fastest path to your first audiobook is converting content you already have. Ideal source material:
- An existing KDP ebook you've published (especially if it's in a non-fiction how-to category) — the manuscript is already written and validated by Amazon buyers - A short original non-fiction guide you write specifically for this format (8,000–20,000 words is the sweet spot for audiobooks under 3 hours) - Public domain content — books published before 1928 in the US are in the public domain. Practical how-to books from that era (gardening guides, self-improvement, business basics) are evergreen and require no rights clearance
What works well in audiobook format: Non-fiction how-to guides, personal development, business, productivity, and self-help. Categories where listeners want actionable information they can absorb during a commute or workout.
What works less well: Highly visual content (anything that depends on charts, diagrams, or tables), technical manuals with code or data, and fiction (harder to compete with professional voice actors who specialise in character differentiation).
Target length: 1–3 hours finished audio (roughly 9,000–27,000 words of manuscript). Under 1 hour is perceived as too short for paid audiobooks on Audible. Over 3 hours dramatically increases production time.
If you don't have existing content, ask Claude: *"Give me 10 short non-fiction audiobook ideas in the [personal finance / productivity / health] space that are 1–2 hours long and would attract Audible buyers searching for practical guidance."*
Pro tip
Your first audiobook should convert your best-selling or highest-reviewed KDP ebook if you have one. Built-in readers who already loved the written version make the ideal early audiobook reviewers.
Step 02 · 1–2 hrs
Prepare your manuscript for narration
Audio narration from AI requires a clean, narrator-ready manuscript. Issues that cause poor AI narration output are almost always preventable at the manuscript stage.
Manuscript cleanup checklist: - Remove or replace visual elements: tables become "the following table shows" + verbal description; bullet lists become flowing prose or numbered sentences - Expand abbreviations: "etc." → "and so on", "e.g." → "for example", "U.S." → "United States" (ElevenLabs handles most standard abbreviations, but explicit expansion prevents misreadings) - Add pronunciation guides in square brackets for unusual proper nouns, technical terms, or names: "Feynman [FYN-man]" - Mark chapter breaks clearly: use a consistent format like "CHAPTER ONE: [Title]" — this makes splitting the audio into chapters straightforward - Remove URLs and hyperlinks: replace them with verbal descriptions ("visit the resource section at the back of this book") - Standardise numbers: write out numbers below 100 ("twenty-five" not "25") for cleaner narration pacing
Save your final narrator-ready manuscript as a clean .txt or .docx file. You will generate audio chapter by chapter, so organise the manuscript into clearly separated chapter files if the book has more than 5 chapters.
Pro tip
Read a page of your manuscript out loud before generating audio from it. If you stumble on anything, rewrite it — ElevenLabs will produce the same stumble at scale.
Step 03 · 3–4 hrs (for a 2-hour audiobook)
Generate narration chapter by chapter with ElevenLabs
Log in at [elevenlabs.io](https://try.elevenlabs.io/yit8rlknumoj). You need a Creator plan ($22/month) for commercial rights — do not use the free or Starter plan for audiobooks you intend to sell.
Voice selection: Browse the Voice Library and select 1–2 voices for testing. For non-fiction audiobooks, look for voices tagged "narrative", "audiobook", or "calm conversational". Test the same 2–3 paragraphs of your manuscript with each shortlisted voice. Pick the one that feels most authoritative and clear at a comfortable listening pace.
Using Projects (recommended for long-form): ElevenLabs has a Projects feature designed specifically for long-form audio like audiobooks. It allows you to: - Upload entire chapters as text - Generate audio with consistent voice and pacing throughout - Regenerate specific sections without redoing the whole chapter - Export chapter audio files individually
Go to Projects in ElevenLabs → create a new Project → upload your first chapter's text → generate. Review the output carefully — listen for mispronunciations, awkward pauses, and pacing issues. Retype problematic words or add punctuation to control pacing before regenerating.
Common ElevenLabs issues in audiobooks: - Long sentences without natural pauses → add commas or em-dashes to create breathing room - Acronyms read as letters instead of words → spell out or phonetically guide them - Place names and proper nouns mispronounced → add phonetic spelling in brackets - Emotionless delivery on high-energy passages → use the stability and style sliders to increase expressiveness
Generate each chapter individually and export as MP3 at 192kbps or higher.
Pro tip
Generate one chapter first and listen to the full audio before generating the rest. Catching a voice selection or pacing issue after generating 10 chapters means regenerating everything.
Step 04 · 2–3 hrs
Edit and master audio in Audacity
Download Audacity for free at [audacityteam.org](https://www.audacityteam.org). It handles everything you need: noise reduction, volume normalisation, silence trimming, and export formatting.
ACX audio requirements (your quality standard): - Bit rate: 192kbps MP3 or higher - Sample rate: 44.1 kHz - RMS volume: -23 to -18 dBFS - Peak: no louder than -3 dBFS - Noise floor: below -60 dBFS - Silence before and after: 0.5–1 second of room tone at the start and end of each file
Audacity workflow for each chapter:
1. Import the ElevenLabs MP3 into Audacity (File → Import → Audio) 2. Noise reduction: if there's any background hiss in the ElevenLabs output (rare but possible), use Effect → Noise Reduction. Select 1 second of silence as the noise profile, then apply at default settings 3. Normalise: Effect → Normalize → set peak amplitude to -3.0 dB 4. Check RMS: use the ACX Check plugin (downloadable free) to verify your RMS level hits the -23 to -18 dBFS target. If too quiet, use Effect → Amplify. If too loud, bring it down 5. Trim silence: trim any long silences at the start or end, but leave 0.5–1 second of room tone 6. Export: File → Export → Export as MP3 → set bitrate to 192 kbps
Repeat for each chapter file. Label files clearly: "01-introduction.mp3", "02-chapter-one.mp3", etc.
Pro tip
Download the free ACX Check Audacity plugin — it automatically checks whether your audio meets ACX specs and flags the specific issues. This saves hours of manual testing.
Step 05 · 1–2 hrs
Publish on ACX for Audible and Amazon
ACX (Amazon's Audiobook Creation Exchange) is how you get your audiobook on Audible and Amazon. Go to [acx.com](https://acx.com) and sign in with your Amazon account.
Claiming your title: Search for your book's title in the ACX search. If you're the KDP publisher, it should appear. Click "This is my book" → "I will narrate this book myself."
Royalty options — this is a key decision: - Exclusive (40% royalty): your audiobook is sold only through Audible/Amazon for 7 years. Higher royalty rate, but you cannot use Findaway Voices simultaneously - Non-exclusive (25% royalty): you keep the right to distribute elsewhere. You earn 15% less per sale, but you can also use Findaway Voices for Apple Books, Chirp, and library distribution
For this playbook: choose non-exclusive. The combined income from ACX non-exclusive + Findaway Voices almost always exceeds ACX exclusive alone, especially once library distribution (OverDrive, Hoopla) kicks in.
Uploading your audio: - Upload your chapter files in order (ACX requires separate files per chapter/section) - Upload a retail audio sample (a 1–5 minute preview — typically your introduction) - Fill in metadata: title, author, narrator (you), language, categories - ACX review takes 14–30 days for audio quality check
Pricing: ACX sets the retail price based on audiobook length — you don't set a specific price. Audible subscribers pay with credits; non-subscribers buy at the standard price. You earn a royalty on every transaction.
Pro tip
If ACX rejects your audio for quality reasons, they will specify exactly which spec was not met. Fix that single issue and resubmit — don't regenerate audio you don't need to.
Step 06 · 1 hr
Publish on Findaway Voices for non-Amazon distribution
Findaway Voices (part of Spotify) distributes your audiobook to 40+ retail and library partners that ACX does not reach: Apple Books, Chirp, Barnes & Noble Nook, OverDrive (public libraries), Hoopla, Scribd, and Spotify.
Go to [findawayvoices.com](https://findawayvoices.com) and create an account. Upload your edited chapter audio files — the same files you submitted to ACX (you do not need separate masters).
Metadata entry: - Title, author, narrator, description, language, categories - AI narration disclosure: indicate that the audiobook is AI-narrated per Findaway Voices' current content guidelines. Check their policies at the time of submission as requirements can evolve - Cover image: 2,400 × 2,400px JPEG at 72 DPI minimum (use your KDP cover if the dimensions match, or create a square version in Canva)
Pricing and revenue share: you set your retail price. Findaway Voices takes approximately 20% of net revenue; you keep approximately 80%. Verify current terms at findawayvoices.com as rates can change.
Timeline: Findaway Voices typically reviews and distributes within 2–3 weeks. Library platforms (OverDrive, Hoopla) may take an additional 2–4 weeks to appear.
The library income channel: OverDrive and Hoopla pay per checkout — each time a library patron checks out your audiobook, you earn a royalty. For evergreen non-fiction titles, library checkouts can generate steady income for years, separate from retail sales.
Pro tip
Your audiobook cover must be square (1:1 ratio) for most platforms. If your KDP cover is not square, open Canva, create a 2,400 × 2,400px canvas, and reflow your cover design into the square format.
Frequently asked questions
Bottom line
Ship it.
The ElevenLabs + ACX + Findaway Voices stack is the clearest path to passive audiobook royalties for creators who don't want to record themselves or hire a narrator. The production cost is your ElevenLabs subscription (Creator at $22/month is the minimum) and your time — roughly 6–9 hours per audiobook. The distribution is free on both platforms. The income compounds slowly: a single title earns modest monthly royalties; a catalogue of 3–5 titles in a specific niche area generates meaningful passive income that continues for years with no ongoing work. The key variable is ACX's evolving policy on AI narration — verify their current guidelines before submitting. Everything else in this workflow is stable and proven.
