How to Create an Audiobook for Your Book (2026 Guide to Cost, Narration and Distribution)

How long will your audiobook be, and what does that mean for cost?

Audiobooks are measured and priced in finished hours: one hour of final, edited audio. Narration averages about 9,300 words per finished hour, so a 90,000-word novel runs roughly 9.7 hours. That number drives narrator fees, production time and, on some platforms, the price listeners pay.

A narrator needs several hours of recording, editing and proofing to produce one finished hour, which is why audio is priced per finished hour rather than per hour worked. The Audiobook Length Estimator turns your word count into a finished-hour figure in seconds, so you can budget before you contact anyone.

Before you record, read your manuscript with audio in mind. Tables, footnotes, image captions, URLs and long lists do not work when spoken. Decide how to handle each one: describe a diagram in a sentence, move links to a PDF companion, and spell out unusual names so the narrator pronounces them correctly.

Should you use human narration or AI narration?

Professional human narrators commonly charge somewhere in the range of a few hundred dollars per finished hour, and rates vary widely with experience and union status. The result is a performance, with distinct character voices and emotional nuance, which many listeners prefer, especially for fiction with large casts, memoir read by the author, and emotionally driven romance.

AI narration with neural voices costs a fraction of that and is fast, so a title can be in audio within days rather than months. It suits non-fiction, short books, backlist titles and authors testing the market. It is weaker at subtle emotion, multiple distinct characters and humour. Listen to a long sample, not just a polished demo, and check the retailer's current rules on AI-narrated titles, because policies differ between stores and change.

Many indie authors start with AI to see whether a book finds an audio audience, then commission a human narrator for the titles that earn it. A third option is narrating it yourself. That is free in cash terms but demands a quiet space, decent microphone, stamina and editing skill, and poor audio is the quickest way to earn bad reviews. CruxOne, which is used in a web browser, offers audiobook narration with neural voices, with ACX-compliant MP3 and chaptered M4B output.

How do you hire a human narrator?

On ACX you post an audition script, usually a passage with dialogue, and narrators submit samples. You can pay per finished hour or offer a royalty share. Per finished hour gives you full control of the rights and better terms later. Royalty share costs nothing up front but ties you to the narrator for the contract period and attracts fewer experienced narrators.

Judge auditions by listening to the same passage across candidates. Check consistency of tone, clear diction, natural pacing and how they handle dialogue. Ask for a short paid or sample chapter before committing, agree deadlines and the number of revision rounds in writing, and give the narrator a pronunciation sheet.

Proof the finished files yourself, or hire someone to. Listen with the manuscript in front of you for mispronunciations, missed lines, breaths, mouth clicks and inconsistent volume between chapters. Raise corrections in one batch rather than piecemeal.

What are the technical requirements for an audiobook?

ACX has strict audio specifications, and files that miss them are rejected. At the time of writing, each file should measure between -23 and -18 dB RMS, with peaks no higher than -3 dB, a noise floor below -60 dB RMS, and a short stretch of room tone at the start and end. Files are MP3 at 192 kbps or higher, constant bit rate, 44.1 kHz.

Each chapter is normally its own file. You also need an opening credits file with the title, author and narrator, a closing credits file, and a short retail sample. Keep individual files within ACX's current length limit and confirm the latest rules on its help pages, since specifications can be updated.

Other retailers and distributors may accept different formats, such as a single chaptered M4B, so check each destination. Producing through a tool that outputs to spec removes much of the guesswork, but always run a final listen and a check with an audio meter before uploading.

Where should you sell it: exclusive or wide?

Audible, Amazon and Apple are reached through ACX. ACX offers a standard exclusive arrangement and a non-exclusive one. Exclusive pays a higher royalty rate and commits you for a long contract term, currently seven years, while non-exclusive pays a lower rate but lets you sell elsewhere. Rates and terms can change, so confirm them before signing.

Going wide means using distributors to reach Apple Books, Kobo, Google Play, Spotify and library platforms. Libraries and subscription services can bring in listeners who would never pay full price, but per-sale earnings vary. The Audiobook Royalty Calculator helps you compare the maths for your own price and length.

Wide suits authors building a long catalogue who value reader choice. Exclusive can suit authors whose audience is already on Audible. Whichever you pick, read the contract, note the termination terms, and keep your master files safe. Our guide to publishing wide covers the wider trade-offs.

Is an audiobook worth making, and how do you promote it?

Production costs money up front, so an audiobook usually makes most sense once a title has steady ebook or print sales that suggest an audience. Cheaper AI narration lowers the risk and lets authors test earlier. The Format Earnings Calculator can show how an audio edition might change your income from one book.

Promotion works much like ebooks, with a few audio-specific levers. Link the audiobook from the ebook's product page and your website, tell your email list, and offer review copies to listeners and audio-focused reviewers. Your audiobook cover must also work as a square thumbnail, so check it at small size.

Be realistic about timing. Plan the audio release alongside or shortly after the ebook, build in time for revisions and retailer review, and treat audio as a long-term asset that sells slowly alongside the rest of your catalogue.

Frequently asked questions

How much does it cost to make an audiobook?

Human narration is priced per finished hour and usually runs to a few thousand dollars for a novel, depending on the narrator. AI narration costs far less. Check current rates.

How many hours is a typical audiobook?

About one finished hour per 9,300 words, so a 90,000-word novel is roughly 9.7 hours.

Should my audiobook be exclusive to Audible?

Exclusive pays a higher ACX royalty but commits you for seven years. Non-exclusive pays less per sale but lets you also sell on Apple, Kobo, Spotify and in libraries.

Can I narrate my own audiobook?

Yes, and it costs nothing in fees. You need a quiet room, a decent microphone and editing skills, because the files must meet strict technical specs.

Is AI narration good enough for an audiobook?

For many non-fiction and shorter titles, yes. It is weaker on emotion and distinct characters, so listen to long samples and check each store's current AI policy.
