How to Record an Audiobook: An ACX-Ready Production Guide

Set the production destination before the first take

An audiobook is not just a long recording session. It is a long-form listening experience that needs to stay comfortable, consistent, and intelligible from the opening credit through the final chapter. Before the first take, decide where the project will be distributed, who is narrating, what the finished timeline looks like, and whether a publisher or rights holder needs a particular delivery package.

That decision affects the entire workflow. A narrator recording for ACX needs a different handoff plan than someone producing a private educational title or an audio companion for an existing audience. Establish the target, chapter structure, narrator credits, and release deadline early so the recording, editing, and final delivery move in the same direction.

Build a predictable narration space

Consistency is the foundation of audiobook recording. The microphone, room, distance from the capsule, gain setting, and monitoring level should be repeatable from session to session. A clean, quiet space gives the narrator room to perform naturally without forcing heavy cleanup later. Small changes in room tone or microphone position can become obvious when a listener moves from one chapter to the next.

You do not need to imitate a commercial booth at home, but you do need to control the variables you can. Choose the quietest available room, limit reflective hard surfaces near the microphone, turn off avoidable noise sources, and capture a short, consistent room tone. For an in-studio project, the engineer can set that foundation before the narration begins. For a remote project, a guided setup makes the same decisions deliberate rather than improvised.

Record in a way that makes editing easier

A calm pace produces a cleaner edit. When a line needs to be corrected, leave a brief pause, restart the phrase cleanly, and continue with the same performance energy. Avoid stopping and searching through the script in the middle of a paragraph whenever possible. Clear pickups give an editor enough context to preserve the intended rhythm of the narration without making the chapter sound pieced together.

Chapter organization matters as much as the take. Keep each chapter or section clearly labeled, note retakes and pronunciation decisions, and maintain a backup copy of each recording session. This does not make the process rigid. It protects the narrator from having to recreate decisions later and gives the editorial stage a reliable map of the book.

• Use the approved manuscript version and mark pronunciation or character notes before recording
• Keep microphone position, gain, and room setup consistent across sessions
• Leave a clean pause before a pickup, then repeat the complete phrase or sentence
• Name and back up every chapter session before ending the day

Understand ACX-ready editing, mixing, and mastering

Post-production is where raw narration becomes a finished listening experience. Editing removes distractions such as false starts, unwanted mouth noise, clicks, and unintended pauses while keeping the read natural. Mixing focuses on stable tone and intelligibility. Mastering and quality control then prepare the final chapter set for its intended distribution path.

For ACX delivery, current requirements include human narration, one chapter or section per file, consistent sound and formatting, average loudness between −23 dB and −18 dB RMS, peaks no higher than −3 dB, a noise floor no higher than −60 dB RMS, and 192 kbps or higher CBR 44.1 kHz MP3 files. ACX makes the final acceptance decision, but planning for these targets early keeps technical review from becoming a last-minute surprise.

Choose the recording workflow that supports the narrator

Houston authors and narrators can record in a professionally prepared Lunar Mansion session. The studio environment makes it easier to establish a repeatable microphone chain, capture clean source audio, and keep the engineer involved from the start. That can be especially useful for a first audiobook, a performance with multiple voices, or a project that needs close production coordination.

Remote audiobook recording can also be a practical option when travel is not the right fit. Lunar Mansion can support approved remote projects with a shipped microphone and interface kit, setup guidance, and an engineer-led session using a consent-based screen-share workflow. The goal is not to make remote recording feel anonymous. It is to give the narrator a clear, supported path from the first chapter through post-production and final delivery.
