You write memoir or narrative non-fiction where your own voice is the product. You have time to learn audio editing. You have one book and a tight budget.
Every method, every cost and every step - from choosing how to narrate your book to publishing it on Audible, Apple Books and Spotify. Written for self-published authors.

Audiobook revenue in the US has grown every year for ten consecutive years. Listeners spend an average of eight hours a month consuming audio content and they pay for it. Yet most self-published authors skip audio entirely because they believe the production cost is out of reach.
This guide covers every available method - from recording yourself in a closet to using AI production software - so you can choose the right path for your budget, your timeline and the kind of books you write.
| Method | Cost per book | Time to retail | Quality ceiling |
|---|---|---|---|
| Self-recording (DIY) | $200-500 setup + time | 4-12 weeks | Depends on skill |
| Human narrator (ACX / Findaway) | $1 600-5 000 | 6-12 weeks | Highest |
| AI software (AudioBook Factory) | $129-499 | Under 1 hour | Studio grade |
Self-narration works well if your voice suits your genre, you can commit to the recording time and you are willing to learn basic audio editing.
A walk-in closet stuffed with clothes absorbs enough echo for a usable recording. You need a condenser microphone ($100-200), an audio interface ($100-150) and free software like Audacity or GarageBand.
Read each chapter as a separate session. Edit out mistakes, normalise loudness to -23 LUFS RMS and export to 192 kbps MP3. Budget 4-6 hours of work per finished hour of audio.
Audible (ACX) requires -23 to -18 dBFS RMS, -3 dBTP peak ceiling, at least 5 seconds of room tone and stereo or mono MP3 at 192 kbps. Most free mastering plugins can hit this spec.
A professional narrator gives you the highest possible quality ceiling. It is the right choice for books where the author's voice performance is part of the brand, or for literary fiction where emotional nuance matters most.
ACX (Audible's platform) connects authors and narrators. Post your book, receive auditions and negotiate a rate (per finished hour) or a royalty share. Findaway Voices and Voices.com are alternatives with broader voice libraries.
Provide a pronunciation guide for character names, invented terms and foreign words. Include chapter-by-chapter tone notes - tension, humour, pace. Good narrators use these to act the text, not just read it.
Most narrators send 15-minute samples per chapter for approval. Budget two rounds of revisions. Full production takes four to eight weeks depending on the narrator's schedule.
Cost note: professional narrators charge $200-500 per finished hour. A 70,000-word novel produces roughly eight to ten hours of audio. Total cost: $1,600-5,000 for narration alone, before mastering and distribution.
AI narration has crossed the quality threshold where a retail listener cannot reliably distinguish it from a human narrator, especially in non-fiction and genre fiction. The gap between the best AI narration and a mid-tier human narrator has closed considerably since 2024.
The workflow with AudioBook Factory looks like this:
Drop your EPUB or DOCX. The software cleans the text, normalises punctuation and numbers, and detects chapter structure. No formatting prep required on your side.
Choose a narrator from the Studio or Premium voice library. For fiction, the software detects characters in your prose and assigns a distinct, stable voice to each one - a full cast, automatically.
AI applies scene-aware prosody, emotional range and breath pauses. Each chapter is mastered to -23 LUFS retail spec. Preview a chapter before generating the full book.
Download retail-ready files for ACX, KDP, Apple Books, Kobo and Spotify - or auto-publish. An optional podcast feed and YouTube video are generated at the same step.
The full production of a 50,000-word novel takes under an hour. Cost: from $129 per book for Studio voice, or $499 for Premium multi-voice actor-grade narration. For authors with multiple titles, a monthly subscription makes more sense.
| Retailer | Format | Loudness | Peak | Notes |
|---|---|---|---|---|
| ACX / Audible | MP3 192 kbps | -23 to -18 dBFS RMS | -3 dBTP | 5s room tone required |
| Apple Books | MP3 or AAC | -23 LUFS | -1 dBTP | AI declaration required |
| Spotify / INaudio | MP3 128+ kbps | -14 LUFS integrated | -1 dBTP | AI disclosure required |
| Kobo / Walmart | MP3 128+ kbps | -23 LUFS | -3 dBTP | Via aggregator |
AudioBook Factory outputs files pre-mastered to ACX spec and handles the AI-generated audio disclosure required by Apple Books, Spotify and Audible.
Audible / Amazon (ACX) - The largest audiobook marketplace. ACX gives you two options: exclusive distribution (35% royalty, higher rate) or non-exclusive (25%). If you go non-exclusive you can sell on Apple, Spotify and Kobo simultaneously.
Apple Books - The second-largest market. Apple's free AI narration is an alternative but requires giving up your audiobook rights. Producing independently and uploading to Apple Books yourself keeps you in control.
Spotify and Amazon Music - Both now carry audiobooks. Use an aggregator like Findaway Voices or publish through AudioBook Factory's distribution chain to reach both.
Direct sales - A growing route for authors with an existing audience. Payhip, Lemon Squeezy and your own website let you keep 95%+ of revenue.
Podcast as a distribution channel - Publishing chapters as a free podcast feed builds an audience before the full audiobook is released. AudioBook Factory's AI podcast generator handles this automatically.
You write memoir or narrative non-fiction where your own voice is the product. You have time to learn audio editing. You have one book and a tight budget.
You write literary fiction where the narrator's performance is the whole experience. Your budget exceeds $2,000 per book. You want the highest possible quality ceiling.
You have two or more titles to produce. You write genre fiction (romance, fantasy, thriller, sci-fi) or non-fiction. You want retail-ready audio in under an hour at a fraction of studio cost.
Choose your method: self-record (cheap but slow), hire a narrator through ACX or Findaway Voices ($200-500 per finished hour, 4-8 weeks), or use AI audiobook software like AudioBook Factory ($129 per book, under an hour). For most authors with more than one title, AI production is the fastest path to retail.
ACX requires MP3 files at 192 kbps, stereo or mono, 44.1 kHz. RMS loudness must be between -23 and -18 dBFS. The peak ceiling is -3 dBTP. You also need at least 5 seconds of room tone at the start and end. Each chapter is a separate file.
DIY: $200-500 for equipment, then your time. Human narrator: $1,600-5,000 for a typical novel. AI production with AudioBook Factory: from $129 per book. Monthly plans start at $29 for authors producing multiple titles.
Audible (ACX) does not require an ISBN. Apple Books and most aggregators do not require one either. You can register one if you want to track the audiobook separately in library systems, but it is optional for retail distribution.
Yes. ACX accepts AI-narrated audiobooks as of 2024, with a required disclosure in the upload form that the audio was generated with AI. AudioBook Factory includes the correct disclosure language in the file metadata and upload guide.
