Hi, folks! I hope you’re ready to learn, because today, I’d like to kick off fall audiobook production lessons with three facets of your post-recording process:
Editing, QC, and Spacing
Audiobook editing is both an art and a skill. The aim is to achieve a clean, professional-sounding audiobook that elevates the source material. It consists of a two-step process commonly referred to as “Editing and QC.”
Step 1: Editing:
- Remove extraneous sounds from your recording (mouth noises, pops, keyboard clicks, etc.).
- Modify the pace of narration, if necessary.
- When appropriate, portions of the recording that are edited out are replaced with clean room tone.
Step 2: QC (Quality Control):
- Listen to the audio while reading the manuscript to ensure they match exactly.
- Mark down any errors (misreads, mispronunciations, or noises you can’t edit out) to a QC sheet, which will be used when you rerecord. You can find the QC sheet Audible Studios editors use here.
Once you’ve completed the QC step, you’ll rerecord the errors you’ve marked and re-insert them into your original audio files. These rerecorded sections of audio are sometimes called “pickups.”

Audible Studios’ editors aim for a specific ratio of time spent on the edit or QC to the audiobook’s overall running time to ensure that these steps fall within the schedule and budget of the full production.
- When editing, the ratio should be 3:1, or three hours spent editing for every one hour of recorded time.
- For the QC process, the ratio should be 1.2:1, or 72 minutes of QC for every 60 minutes of recording.
If you find yourself working faster than this, I recommend a second edit and QC pass to make sure you haven’t missed an error. If you’re consistently taking longer than recommended, you may be focusing too much on certain aspects of the edit. Try listening to some samples and reading reviews on Audible to learn what really bothers listeners.
One way to stay within these guidelines is to speed up the playback in your DAW, so that you cover more ground than at the normal speed. While this may take some practice, it can help ensure that your editing is done quickly and correctly. If you go this route, I recommend you start at 1.2x speed, working your way up to 1.5x speed, as you get more comfortable.

When it comes to spacing, ACX’s requirements help ensure that your audiobook productions stand shoulder to shoulder with all the titles on sale at Audible, Amazon, and iTunes. Our requirements state:
Each uploaded file must have between 0.5 and 1 second of room tone at the head, and between 1 and 5 seconds of room tone at the tail.
Why is this so important? Think of the spacing within your audiobook as the layout of words on pages and of pages within chapters of a print or eBook. Without proper spacing denoting the end of a scene or beginning of a new chapter, your listener could feel lost within the book, and the impact of your narration may be lessened. The easiest way to follow this requirement is to paste in the appropriate amount of clean room tone at the head and tail of each file.
I hope this gives you a good understanding of one of the most important aspects of audiobook production. Check out my other posts for more audiobook production education, and come back soon for more tips straight from The Audio Scientist.
Quick Tips for Editing and Spacing:
Make sure you have clean room tone. If you don’t, you could be creating more problems than you’re solving.
Record new room tone any time you change your microphone or studio settings. The old room tone may not match the sound of the new recording you are applying it to.
Always wear headphones. You need to be in an isolated environment to ensure the narration stays natural and any cut is seamless.
Get into the habit of marking everything. If you find a click, pop, noise, or QC error, make sure you mark the instance within your DAW! That way, when you go back to make the edits, you won’t have missed anything.
