This sample should start with narration, not opening credits or music. The sample must non include explicit textile. This sample is used by customers to preview of your audiobook.'"
Upload The Audio In Sections
ACX require each section e.g. forward, Chapter 1, Chapter ii etc. be uploaded as an individual file. In other words you tin can't upload the entire book in one sound file, you must create, edit, mix and and so upload each 1.
ACX say; "Y'all'll be prompted to upload each file individually. Both the opening credits and closing credits must exist separate files. This ensures listeners tin easily navigate between sections, and that skipping forwards or backwards moves them forward or back one section."
Include Room Tone
Don't bound into record or end tape quickly as ACX requires room tone. When editing you will need to ensure this space is left at the front and end of each sound recording.

"Each file must have 0.five to 1 second of room tone at its showtime and 1 to 5 seconds of room tone at its terminate. This space is required to ensure titles are successfully encoded in the many formats made bachelor to customers. It likewise gives listeners an audio cue that they accept reached the kickoff or end of a department."

"Each file must incorporate the section header, if contained within the manuscript (e.1000., "Prologue", "Chapter 1", "Chapter 2").
These announcements help the listener understand what section of the book they are listening to without having to await at their player. If a section header is found to be missing during the ACX QA review, you will be contacted to brand revisions which could delay the release of your title. Be consistent - a listener may recollect content is missing if most headers are read only some are non ."
