Learning how to publish an audiobook gives your book a second life with listeners who read while driving, walking, or working. This guide walks you through the full Audible route using ACX, from choosing how your book will be narrated to meeting audio quality rules, setting distribution terms, and passing review. You will also see the costs, royalty choices, and wide options to consider before you commit.
How to Publish an Audiobook on Audible, Step by Step
Audible is owned by Amazon, and most independent authors reach it through ACX, which stands for Audiobook Creation Exchange. ACX connects your ebook or print book to narration, production, and distribution on Audible, Amazon, and iTunes. If your book is already on Kindle Direct Publishing, you can claim it on ACX with the same Amazon account and link the editions together so readers see the audio option on your product page.
The basic flow is simple. First, confirm you hold the audio rights to your book. Second, decide how the book will be recorded. Third, produce clean audio files that meet ACX technical rules. Fourth, upload the files with your cover art and book details. Fifth, wait for quality review and approval, then set your release in motion. Most delays happen in steps two and three, so planning production well matters more than rushing the upload.
Before you record a single word, make sure the text itself is final. Audio is expensive and slow to fix compared with an ebook file. A typo you could correct in minutes in a Kindle file can mean rebooking a narrator, rerecording a chapter, and re-editing the audio. Use our guide on how to proofread your own book before publishing with a final pass checklist to catch errors while changes are still cheap. Read tricky names, places, and numbers aloud too, and note the pronunciation you want.
Choose Your Production Route on ACX
ACX gives you three main routes, and each one changes your upfront cost, your control, and how income is shared.
Narrate the book yourself
Self narration suits memoir, personal development, and books where your voice is part of the promise to the reader. It costs the least in cash if you already have a quiet room and a decent microphone, but it costs the most in time. You will need to record, edit, and master every chapter, or pay an engineer to handle the technical side. Be honest about your stamina and sound quality. Listeners will forgive a simple setup, but they will not forgive echo, background noise, or uneven volume for ten hours.
Hire a narrator and pay upfront
Paying a narrator per finished hour is the most common professional route. A finished hour is one hour of final, edited audio, not one hour spent in the booth. A typical novel of 80,000 words runs about nine hours, because most narrators read at roughly 9,000 to 10,000 words per hour. Professional narrators often charge a few hundred dollars per finished hour, and experienced voices charge more. Paying upfront costs more at the start, but you keep the full royalty share that your distribution terms allow and you control casting, pace, and corrections.
Use a royalty share deal
With a royalty share deal, you pay little or nothing upfront and split your audio royalties evenly with the narrator or producer. This lowers your risk if sales are uncertain, and it can attract a good narrator if your book already sells well in print or ebook form. The trade off is real: you earn half as much from every sale for the full term of the agreement, which is usually seven years on ACX. A royalty share plus option can also sit between the two routes, with a smaller upfront payment plus a share. Read any contract carefully before you agree, especially rules about rights, exclusivity, and what happens if you want to leave early.
Whichever route you choose, hold auditions. Ask for a short sample using your actual opening pages, not a polished demo reel. Listen for clear speech, steady pace, believable character voices, and a tone that matches your genre. Fiction needs acting range. Nonfiction needs warmth and authority without sounding like a lecture.
Meet ACX Audio Specs and Quality Rules
ACX rejects more projects for sound problems than for narration style. Your files need to sound consistent from the first chapter to the last, with no clipping, hiss, mouth clicks that distract, or sudden changes in room tone.
The core public specs are worth learning before anyone records. Each file should be an MP3 at 192 kbps or higher with a constant bit rate, recorded at 44.1 kHz. Audio levels should sit with RMS values between minus 23 dB and minus 18 dB, peaks no higher than minus 3 dB, and a noise floor no higher than minus 60 dB. Files should be mono or stereo, but consistent across the whole book. Each chapter is usually its own file, with opening and closing credits as separate files, and a short retail sample taken from the start of the book.
Structure matters as much as sound. Include a brief silence at the start and end of each file, keep chapter headings spoken in a consistent way, and follow the book order exactly. If your print book has maps, worksheets, or long lists that do not work aloud, decide early how to handle them. You can describe the item briefly, offer a downloadable companion PDF through your own site, or adjust the script with a short spoken note. Do not silently skip content that buyers expect.
Cover art for audio also has its own rules. Audible uses a square cover, at least 2400 by 2400 pixels, in RGB color, without the print book spine or back cover elements. Your ebook cover will need to be adapted, not just stretched. Check that the title and author name stay readable at thumbnail size, because most listeners shop on a phone.
Upload, Review, and Distribution Choices
When production is done, you upload each file to ACX, enter your book description, choose categories, and confirm your territorial rights. Then the project enters a quality review. ACX says review can take several weeks, and first time producers often get a list of fixes on the first pass. Treat that feedback as useful, not personal. Fix the flagged files, reupload only what is needed, and keep notes so your next book passes faster.
Your biggest business decision is exclusivity. If you grant ACX exclusive distribution, your audiobook is sold only through Audible, Amazon, and iTunes, and the standard royalty is 40 percent of the retail based earnings. If you choose non exclusive distribution, the standard royalty is 25 percent, but you keep the right to sell or distribute the same audiobook elsewhere. Neither choice is right for everyone. Exclusive terms pay more per sale and suit authors whose audience lives on Amazon. Non exclusive terms suit authors building a direct store or a wider library presence.
Think about that choice alongside your ebook strategy. If your ebook is enrolled in KDP Select, it must stay exclusive to Amazon as an ebook, but that rule does not force your audiobook into exclusivity. Many authors pair a wide ebook with a wide audiobook, or keep the ebook in Select while taking audio wide. If you are weighing the wider ebook route too, read our companion guide on how to publish a book wide on Apple Books, Kobo, and Google Play and plan both formats together.
Price is the other surprise for new audio publishers. On Audible, you do not set the retail price the way you do for a Kindle ebook. Audible sets the price largely based on length, and many listeners buy with a monthly credit instead of cash. That is why length, completion rate, and reviews matter so much. A well paced book that listeners finish is more likely to be recommended, finished, and reviewed well than a padded book that feels long.
If you do not want to be exclusive to ACX, you have other routes to Audible and beyond. Services such as Findaway Voices and other audio distributors can place your audiobook on Audible plus library and retail platforms like Spotify, Chirp, and library apps, usually for a lower Audible royalty but wider reach. Compare the total picture: royalty rate, library access, production help, and how easily you can update files or change prices later.
How Folio Authors Supports Your Audiobook Release
An audiobook goes wrong most often before recording starts, when the manuscript still has errors, the chapters are uneven, or the publishing plan is unclear. That preparation stage is where Folio Authors fits. Folio Authors is publishing software for independent authors, with assessment, editing, formatting, cover design, and publishing in one dashboard, so the book you record from is the clean, final version.
You can start before you spend anything on production, because your first assessment is free and it includes a 500 word editing sample, with no card needed. That gives you an honest view of whether the text is ready to become audio. If you want human help, a human assessment is $100 and a dedicated editor is $3 per page. The Standard plan is $150 one time and unlocks all Folio tools, while publishing, audiobook, and marketing tools are charged separately. For the book itself, publishing plans start with Amazon KDP at $99, and wider options include 3 Platforms at $399 and 10 Platforms at $799. You keep 100 percent of your rights and royalties on every route.
Frequently Asked Questions
How long does ACX review take?
Review often takes a few weeks, and it can take longer during busy periods or if files need fixes. Build that waiting time into your launch plan. Uploading early and fixing flagged files quickly is the best way to protect your release date.
How much does an audiobook cost to produce?
It depends on length and route. Self narration costs mostly time and basic equipment, royalty share costs little upfront but halves your royalty income, and hiring a professional narrator per finished hour is the largest upfront cost. Longer books cost more because you pay for more finished hours.
Should I choose exclusive or non exclusive distribution on ACX?
Exclusive distribution pays a higher standard royalty of 40 percent but limits you to Audible, Amazon, and iTunes. Non exclusive pays 25 percent and lets you distribute elsewhere. Choose based on where your listeners are and whether wide reach or a higher rate matters more to you.
Can I publish an audiobook without an ebook?
ACX works best when your audiobook can link to an existing Kindle or print edition, which helps readers find the audio version. You should have your rights, your finished text, and your book details ready first. Linking editions also helps your reviews and sales pages work together.
What if my audio fails quality review?
ACX will list the problems, such as levels, noise, or file errors, and you can fix and reupload the affected files. Most first projects need at least one round of fixes. Working with an experienced narrator or engineer reduces the number of issues.
The Bottom Line
Publishing on Audible is a production project first and an upload second. Confirm your rights, pick the narration route that fits your budget, record to ACX specs from day one, and choose exclusivity with your eyes open. Do that, and your audiobook can earn alongside your ebook and print editions for years, reaching readers who may never have picked up the book in another format.
