What is it like to produce an audiobook through ACX?
My own sales data puts audiobooks ahead of Kindle, paperback, and hardcover combined, so every ghostwriting client hears the same advice from me: plan for audio from the start. For more, see book marketing that works and how AI narration fits in. ACX (the Audiobook Creation Exchange) is Amazon’s production platform that connects authors with narrators and distributes finished audiobooks through Audible and iTunes. It’s the most common path to audiobook publishing, though other routes exist, and it’s the one I’ve put my own books through.

My ACX Audiobook Recommendations
- Sales dominance. I consistently sell more audiobooks than Kindle, paperbacks, and hardcovers combined. That’s not an industry trend. That’s my actual sales data.
- Increased visibility. Think of every book format as a funnel. An audiobook adds another layer and gives readers another way to find your work. The more formats available, the greater the chance of reaching a diverse audience.
- Ease of production. Producing audiobooks is simpler than many people believe. Given their rising popularity, there’s no good reason to skip creating one.
- Cover designing. If you’re already getting a cover for your Kindle or paperback, include the audiobook cover in the order. It’s a square format with specific dimension requirements. Many designers offer to include it free or at a steep discount.
- Royalty decisions. I opted for a royalty split with a voice artist and found the limitations frustrating. You relinquish certain rights for about seven years, so consider this method carefully.
- Explore other platforms. While ACX has its merits, Draft2Digital has expanded into audiobook distribution. I’ve earmarked that platform for future projects.
- Invest in voice artists. For one book, I paid a voice artist roughly $200 per finished hour, totaling 8 hours. That investment gave me complete rights and full control over the audiobook.
- Take your time choosing a narrator. I’ve rushed this decision before and regretted it. Always allocate enough time to listen to every audition carefully.
- Consider narrating it yourself. If you have a clear, engaging voice and can convey your story compellingly, it’s worth doing. You’ll need a quality microphone and a quiet recording space.
- Expect ACX rejections. ACX enforces strict technical specs before approving any audiobook. Every book I’ve submitted was rejected on the first pass, but the voice artists fixed the issues at no extra charge each time.
- Ghostwriting clients should consider audio. I consistently advise my ghostwriting clients to create an audiobook edition. Several who took that advice narrated their books personally, adding an intimate touch that a hired voice can’t replicate.
Why Audiobooks Matter for Your Book
Every format your book exists in is a separate funnel. Kindle reaches one audience. Paperback reaches another. Hardcover reaches a third. Audiobook reaches people who may never pick up any of those formats: commuters, gym-goers, people who consume content while doing something else with their hands and eyes. Some readers consume exclusively through audio. If you don’t have an audiobook, those readers don’t exist for you. They’re choosing between your audiobook and someone else’s.

This matters especially for nonfiction authors (executives, consultants, coaches) whose books are credibility tools. The person driving to a meeting who listens to your book on the way there’s exactly the kind of prospect you want. Audio puts your ideas in their head at the moment they’re most receptive.
What are the two ACX royalty models?
ACX gives you two ways to pay your narrator, and this decision has long-term consequences.
At one point I had 27 audiobooks out there. I picked some good narrators and some bad ones, so some of those books sound great and some I’d really like to redo. Under a royalty split you have to wait seven years for that. I took the split back then because I had less money. I wouldn’t now. I’d do just a couple of big ones and pay the narrator outright, and never one who cranks it through AI.
Royalty share means you pay nothing upfront. The narrator works for a percentage of future sales, typically a 50-50 split. Sounds appealing, especially if you’re watching costs. But here’s the catch: you’re locked into that split for about seven years. You lose control over pricing and promotional strategies for the duration. I went this route on one book and found the limitations frustrating. Think carefully before giving up that much control for that long. I don’t recommend the royalty split. Do it in-house, or hire somebody to do the speaking for a one-time charge.
Pay per finished hour means you hire the narrator at a flat rate. I’ve paid roughly $200 per finished hour, which came to about $1,600 for an eight-hour book. That’s real money upfront, but you own the audiobook outright. Full rights. Full control over pricing and distribution. If the book sells well, every dollar above production cost is yours. Generally, expect a narrator to charge between $200 and $500 per finished hour. The charge is based on how long the finished book turns out to be, and how long the recording takes them doesn’t enter into it.
The AI-Enhanced Book Promotion Handbook breaks down production economics in more detail: professional narration typically runs several hundred to several thousand dollars per finished hour depending on narrator experience and production complexity. A ten-hour audiobook might cost anywhere from three to ten thousand dollars for quality production.
How do you choose a narrator on ACX?
I’ve rushed this decision before and regretted it. Don’t do what I did. A great narrator transforms a good book into a convincing audio experience. A poor narrator makes even excellent writing tedious to listen to. The difference between a $150/hour narrator and a $400/hour narrator isn’t always quality, but the difference between someone you auditioned carefully and someone you picked in a hurry almost always is.
ACX lets you post your book and receive auditions from narrators.
Listen to every audition completely. Don’t pick the first voice that sounds decent. Listen for pacing, emotional range, pronunciation accuracy, and whether the voice matches your book’s tone. If your book is a serious leadership guide, a narrator who sounds like a morning radio host will undermine your credibility. Pick on quality over price, because you’re only doing this once and you’re paying per finished hour. ACX has real voice actors who do this for a living, and it has amateurs. You don’t want an amateur.
Ask how a narrator handles scene breaks, the ornamental gaps inside a chapter where the time or place jumps. The usual standard is a pause of about two to three seconds, clearly longer than the second or so between paragraphs, with a change of tone on the first line after it. Most regular listeners hate sound effects there. A page-turn noise or a chime pulls them out of the story. A few fantasy series use a short signature sound for breaks and their listeners enjoy it, but silence is the safe choice.
The rest of that job belongs to the writer. A listener can’t see the ornament on the page, so the first sentence after a break should say where and when we are.
For ghostwriting clients, I consistently recommend narrating your own book if you have a clear, engaging speaking voice. When someone reads your book and then hears you on a podcast or at a conference, the voice matches the authority. Several of my clients have narrated their own audiobooks, and the personal touch adds something a hired voice can’t replicate.
Why does ACX reject audiobook files?
Every audiobook I’ve submitted to ACX has been rejected on the first pass. Every single one.
The rejections have nothing to do with content quality. ACX enforces strict technical specifications: file format, volume levels, room tone, noise floor, consistent audio quality across chapters. I respect them for it, even when a bounce costs me another week, because they’re protecting the listener, and a hissy, uneven audiobook would do far more damage to an author’s reputation than a short delay.
The rejections always came with specific feedback: background hiss in chapter four, inconsistent volume between chapters, room tone that didn’t match their spec. In every case, the voice artists fixed the issues at no extra charge.
It’s understood as part of the production process. But it adds time. Build a buffer into your timeline for at least one round of technical corrections.
Beyond ACX: Other Distribution Options
ACX distributes through Audible and iTunes. That covers the majority of the audiobook market. But it’s not the only option.
Non-exclusive distribution through services like Findaway Voices gives you access to additional retailers including Apple Books, Kobo, and library systems. You sacrifice some revenue potential on Amazon in exchange for broader reach and rights retention. Draft2Digital has also expanded into audiobook distribution, and I’ve earmarked that platform for future projects.
The tradeoff is the same one that runs through all publishing decisions: exclusivity for higher per-unit revenue versus wide distribution for broader reach. I don’t believe there’s a universally right answer, and I get annoyed when people insist there is. It depends on your goals, your audience, and how much of your business you’re willing to let run through Amazon’s ecosystem.
The Audiobook Cover
If you’re already getting a cover designed for your Kindle or paperback edition, add the audiobook cover to the order.
It’s a square format with specific dimension requirements, different from the rectangular covers used for print and ebook. Many designers will include it for free or at a steep discount when you’re already paying for the other formats. Don’t skip it and don’t just crop your existing cover. A well-produced audiobook in Audible’s library looks amateur behind a lazy square crop.
Should You Narrate Your Own Audiobook?
If you have a clear, pleasant speaking voice and can convey your material with energy and natural pacing, yes, consider it. Especially for nonfiction where the author’s authority matters. You’ll need a quality microphone (not your laptop’s built-in mic), a quiet recording space (not your living room with the HVAC running), and patience for the editing process. Recording a clean audiobook takes significantly longer than just reading the text aloud. Expect multiple takes, technical retakes, and post-production cleanup.
The book on this: Publish Your Book is 198 pages on every major publishing path, how the platforms really differ, and how to pick the one that fits the goal you have for the book.
But the result is worth the effort. Your audience hears the real you. For executives and thought leaders whose books drive their business development, that carries real weight.
Is ACX worth it for producing an audiobook?
Audiobooks are where a growing segment of your audience lives, and they’re the format I sell the most of personally. If you’re investing in a ghostwritten book, putting months of interviews, drafts, and revisions into a manuscript, skipping the audiobook edition leaves money and reach on the table.
Plan for it from the start. Budget for a quality narrator or prepare to record it yourself, and get your square cover designed alongside your other formats. Audiobooks aren’t hard to make. If you’ve got a good voice and the patience, you can speak it yourself.
Expect ACX to bounce your first submission, fix it, and move on. I think skipping audio is among the most expensive mistakes an author with a finished manuscript can make, because those listeners don’t wait for you; they go straight to somebody else’s book.
