ACX Production Platform Setup: A Clear Overview
So you’ve written a book, and now you want to hear it. Maybe you’ve already narrated a few chapters on your phone, or maybe you’re starting completely from scratch. Either way, ACX—Audiobook Creation Exchange—is the bridge between your manuscript and Audible, Amazon, and iTunes.
ACX is Amazon’s free production platform where authors and publishers connect with narrators, produce audiobooks, and distribute them to the major retailers. The setup process is straightforward, but the details matter. Here’s what you need to know before you click that first button.
What ACX Actually Does (and What It Costs)
ACX operates on a simple premise: you provide the rights to your book, and the platform handles the technical pipeline between production and retail distribution. You can either narrate the book yourself, hire a narrator through ACX’s talent directory, or upload audio you’ve already produced elsewhere.
The cost structure is where most people get confused, so let’s clear that up:
- Self-production: Free. You record, you upload, you approve. ACX takes no upfront fee.
- Hiring a narrator: You pay per finished hour (PFH). Rates typically range from $50 to $400+ per finished hour, depending on experience. A 10-hour audiobook at $150 PFH runs you $1,500.
- Royalty share: You offer the narrator a 50% royalty split instead of upfront payment. No money changes hands until the book sells.
One important detail: ACX is exclusive to Audible, Amazon, and iTunes. That means you cannot distribute the same audiobook to other retailers like Libro.fm or Spotify while it’s enrolled in ACX’s exclusive program. If you want wider distribution, you’d need to produce elsewhere—but for most independent authors, the reach of Audible’s marketplace makes exclusivity worth it.

Creating Your ACX Account: The Setup Steps
The account creation process takes about ten minutes, but you’ll need specific information ready before you start.
Step 1: Create your author account
Go to acx.com and sign in with your Amazon credentials. If you’ve published through KDP, use the same account. ACX will ask for your legal name, tax information, and payment details. This is standard—you’ll need a W-9 or W-8BEN on file before you can receive royalties.
Step 2: Claim your book
Search for your title in ACX’s database. If your book is on Amazon, it should appear. If it doesn’t, you can manually add it with your ISBN. You’ll need to verify that you hold the audiobook rights—this is a legal declaration, not just a formality. If you published through KDP, your audiobook rights are separate from your ebook rights, so confirm your contract before proceeding.
Step 3: Choose your production path
This is the decision that shapes everything downstream. You’ll select one of three options:
- I’ll narrate it myself: Best for authors with home studio setups and prior audio experience.
- I’ll find a narrator: You’ll enter ACX’s talent marketplace and audition producers.
- I have audio files ready: You’ve already recorded and mastered elsewhere, and you’re just using ACX for distribution.
Step 4: Set your terms
If you’re hiring a narrator, you’ll specify your payment structure (PFH or royalty share), your production timeline, and your rights territory (worldwide or specific regions). You’ll also upload your manuscript so narrators can audition with a sample chapter.
Step 5: Submit for review
ACX reviews your title submission within 72 hours. Once approved, your book goes live in the talent marketplace, and auditions start rolling in.
If your title doesn’t appear in the database after 72 hours, check your email for a rejection notice. The most common reason is missing metadata—your book’s ISBN or ASIN wasn’t matched correctly. You can resubmit with the correct information, but don’t keep resubmitting the same entry. If you’ve tried twice and still get rejected, contact ACX support directly with your ISBN and Amazon product page URL. They can manually match your title.
The Studio Requirements: What You Need for Self-Narration
If you’re planning to narrate your own book, the technical requirements are specific but achievable. ACX has published minimum standards, and they’re worth understanding before you invest in equipment.
Audio specifications:
- Sample rate: 44.1 kHz
- Bit depth: 24-bit
- Format: WAV or MP3 (320 kbps minimum)
- Noise floor: -60 dB or lower
- Peak level: -3 dB maximum
In plain English: you need a quiet room, a decent microphone, and recording software that can export high-resolution files. A USB microphone like the Audio-Technica ATR2100x (around $100) will get you started. The built-in mic on your laptop won’t cut it—the background noise alone will fail ACX’s quality checks.
The room matters more than the mic
You can spend $500 on a microphone and still fail ACX’s checks if your room has echo or hum. Closets with clothing absorb sound well. Heavy curtains help. A reflection filter—basically a curved foam panel that mounts behind your mic—costs around $50 and makes a noticeable difference.
Real talk about editing
A 10-hour audiobook is roughly 100,000 words. At a typical narration pace of 150 words per minute, that’s over 11 hours of raw recording. Editing that down to a polished final product takes another 20-30 hours. If you’ve never edited audio before, budget a full week for a 10-hour book.
Popular free editing tools include Audacity and GarageBand. Both can handle the required export formats, though Audacity’s noise reduction and compression tools are more robust for this specific use case.
Before you record a single chapter, run ACX’s own test. The platform offers a free audio test submission that checks your file against their quality standards. Upload a 60-second sample and wait for the automated feedback. If it passes, you’re good to go. If it fails, the feedback will tell you exactly which spec is off—usually the noise floor. This test saves you from recording hours of audio that will be rejected later.
Finding and Auditioning Narrators on ACX
If self-narration sounds like too much, the talent marketplace is where ACX shines. Thousands of professional narrators list their services, complete with audio samples, PFH rates, and genre specialties.
How the audition process works:
1. Your book goes live in the marketplace with your manuscript attached.
2. Interested narrators record a 15-minute sample from your provided audition script.
3. You receive auditions in your ACX dashboard, usually within a week.
4. You listen, compare, and either accept a narrator or extend the deadline.
What to listen for in auditions:
- Consistency: Does the narrator’s pace stay steady throughout the sample?
- Character differentiation: For fiction, can you tell characters apart without dialogue tags?
- Energy: Does the narrator sound engaged, or are they reading at a monotone?
- Accent and pronunciation: Are they pronouncing names and places correctly?
A concrete example: if you’re writing a fantasy novel with invented names, include a pronunciation guide in your manuscript notes. Narrators appreciate it, and it prevents awkward mid-production corrections.
The royalty share trade-off
Royalty share deals are attractive because they cost nothing upfront. But here’s the math: a 10-hour audiobook at $20 retail earns roughly $7 per sale in royalties. Split 50/50, you’re earning $3.50 per sale. You’d need to sell over 400 copies to match a $1,500 upfront payment. For most first-time authors, that’s a slow road. Royalty share makes more sense for established authors with existing audiences or for backlist titles with steady sales.
If you receive zero auditions after two weeks, your listing probably isn’t attracting talent. The most common fix is your audition script. If you’ve uploaded a full chapter with dense exposition, narrators may skip it. Instead, provide a 500-word excerpt that shows off dialogue, varied pacing, and emotional range. Also check your PFH rate—if you’re offering $50 PFH, you’re competing with hundreds of other listings at that price point. Bumping to $100 PFH often doubles or triples your audition count.
The Production Timeline: What to Expect
Once you’ve selected a narrator, the clock starts ticking. A typical production schedule looks like this:
- Audition period: 1-2 weeks
- Production: 4-8 weeks for a 8-12 hour book
- Your review time: 2-4 weeks (you’ll listen to every chapter)
- ACX quality review: 2-4 weeks after final approval
That’s a 2-4 month pipeline from narrator selection to live on Audible. If you’re on a deadline—say, a book launch tied to a preorder—factor in buffer time. Narrators get sick, editing takes longer than expected, and ACX’s review queue can back up during peak seasons.
The 15-minute check-in
ACX requires narrators to submit a 15-minute checkpoint within the first few weeks. This is your opportunity to catch issues early—wrong pronunciation, pacing problems, or a voice that doesn’t match the audition. Don’t skip this. Fixing a 15-minute sample is much cheaper than redoing 5 hours of audio.
When the narrator misses the checkpoint deadline, you have two options. You can extend the deadline once, which is reasonable if they’ve communicated a delay. But if they miss the checkpoint with no communication, that’s a red flag. ACX allows you to terminate the production and relist the title. It’s better to lose two weeks than to wait two months for a narrator who won’t deliver.
Uploading and Approving Your Audio
Whether you’ve self-produced or worked with a narrator, the final steps are the same.
Chapter-by-chapter approval
ACX requires you to listen to and approve each chapter individually. This is tedious but necessary. You’ll catch things you missed during production: background hums, mouth clicks, or a narrator mispronouncing a character’s name in chapter 12.
The quality check
Once you’ve approved all chapters, ACX runs an automated quality review. It checks for:
- Consistent volume levels
- Background noise
- Proper file formatting
- Complete audio (no cut-off endings)
If a chapter fails, you’ll get a note explaining why, and you’ll need to fix and resubmit. This is the most common point where new producers get frustrated—a single chapter with a low hum can delay your entire release.
Pricing your audiobook
ACX lets you set your retail price within Audible’s guidelines. For most books, that’s between $14.95 and $24.95. You can also set a Whispersync price—a discounted rate for listeners who own the ebook—which often boosts sales by making the audiobook an easy add-on purchase.
If a chapter fails quality review, don’t just fix the one file. Run the same check on the chapters you haven’t submitted yet. If the noise issue exists in one chapter, it’s probably in others. Many producers fix one chapter, resubmit, and then get another chapter rejected for the same issue a week later. That’s how a two-day fix becomes a three-week delay. Check all your files before resubmitting anything.
Common Setup Mistakes and How to Avoid Them
Skipping the rights check
You need explicit audiobook rights. If you published through KDP, check your contract. If you have a traditional publisher, you almost certainly don’t own the audio rights. Trying to produce a book you don’t have rights to can result in your account being suspended and the audiobook pulled.
Ignoring the noise floor
ACX’s -60 dB noise floor requirement is non-negotiable. If you’re recording at home, run a noise test before you start. Record 30 seconds of silence in your recording space and check the levels. If you see anything above -60 dB, you need to treat your room or move locations.
Rushing the audition process
It’s tempting to accept the first decent audition and get moving. But a narrator’s voice will be in your ears for 10+ hours. Listen to multiple auditions. Compare how different voices handle your material. The right narrator can elevate your book; the wrong one can tank it.
Forgetting about ACX’s exclusivity requirement
When you publish through ACX, your audiobook is exclusive to Audible, Amazon, and iTunes for seven years. You cannot sell the same audio files on other platforms. If you want to distribute through Libro.fm or other retailers, you’ll need to produce a separate recording or wait out the exclusivity period.
When ACX Isn’t the Right Choice
ACX is the default for most independent authors, but it’s not the only option. If you’re planning to distribute widely—say, through Findaway Voices or directly to multiple retailers—ACX’s exclusivity requirement will be a dealbreaker.
For authors with established audiences who want maximum reach, producing through a non-exclusive service and distributing to multiple platforms can be more profitable, even with lower per-sale royalties. The trade-off is complexity: you’ll handle your own audio files, metadata, and retailer relationships.
If you’re just starting out, though, ACX’s integrated pipeline—production, distribution, and royalty tracking in one place—is hard to beat.
Your First 48 Hours on ACX
Here’s your practical checklist for getting started:
1. Day 1: Create your account, verify your tax info, and claim your book.
2. Day 2: Decide your production path. If hiring, write a clear book description and audition script. If self-narrating, test your recording setup.
3. Day 3: Submit your title for ACX review and start browsing narrator profiles.
The platform itself is free. The learning curve is real, but manageable. And once your audiobook goes live, the feeling of hearing your words in someone else’s voice—or your own—makes the setup process worth every minute.
ACX’s dashboard will guide you through each step, and their support team responds within a few business days. Start with the basics, get your book live, and refine your process on the next one.
