Final checklist before submitting to ACX
Rejections usually come from small, avoidable issues. Run through this list before upload, or ask the ACX-ready audiobook editors to check the files for you.
Structure
One chapter or section per file, opening credits and closing credits as separate files, and a retail sample of five minutes or less.
Measurements
Every file passes RMS, peak and noise floor checks. All files share the same channel format, either all mono or all stereo.
Listening pass
Play the first and last ten seconds of each file for clipped words and check room tone at head and tail. If anything is uncertain, request a quote for a technical review.
