In lodge to get an audio volume in the Audible shop yous need to first set an ACX account and set up a new projection.

Consistency in audio levels, tone, dissonance level, spacing, and pronunciation gives the listener an enjoyable experience. Drastic changes can exist jarring to the listener and are not cogitating of a professional production. This distracts from the listening feel and may lead to poor reviews and reduced sales."

"Each uploaded file must be free of extraneous sounds such as plosives, mic pops, mouse clicks, excessive mouth dissonance, and outtakes.

Your DAW also has powerful tools you can use such equally the sound editor and the included plugins.
Each File Needs Credits
In add-on to the text of the book sound files for credits need to be included in the files. This is what ACX say;
Your audiobook must include opening and endmost credits that match the championship'south cover fine art.
At minimum, the opening credits must note the proper noun of the audiobook, the proper noun of the author(s), and the name of the narrator(s). Closing credits must, at minimum, state "the end".
Opening Credits Minimum Requirements
-
"[title of audiobook]"
-
"(subtitle if applicable)"
-
Written by [proper name of author]
-
Narrated by [proper name of narrator] Closing Credits Minimum Requirements
-
The End
Include An Sound Sample
ACX say "Your audiobook must include a retail audio sample that is between i and five minutes long. Explicit material is not permitted in the sample. This sample should start with narration, not opening credits or music. The sample must not include explicit material. This sample is used by customers to preview of your audiobook.'"
Upload The Sound In Sections
ACX require each section east.g. forward, Chapter 1, Affiliate two etc. exist uploaded every bit an private file. In other words you can't upload the entire book in one audio file, you must create, edit, mix and so upload each one.
ACX say; "You lot'll be prompted to upload each file individually. Both the opening credits and closing credits must be carve up files. This ensures listeners tin easily navigate between sections, and that skipping forward or backwards moves them forrad or dorsum ane department."
Include Room Tone
Don't leap into record or stop tape quickly as ACX requires room tone. When editing you will need to ensure this space is left at the front and stop of each audio recording. For those who edit dialogue all the time this will feel alien equally we are used to editing as close to the audio every bit possible to reduce room noise. Not in this case. "Each file must have 0.5 to 1 second of room tone at its outset and 1 to 5 seconds of room tone at its end. This space is required to ensure titles are successfully encoded in the many formats fabricated available to customers. It also gives listeners an audio cue that they have reached the beginning or end of a section."
Include Audio Cues
When recording make sure you lot audibly introduce the department y'all are about to read.
"Each file must contain the section header, if contained within the manuscript (e.g., "Prologue", "Affiliate 1", "Chapter two").
These announcements help the listener sympathize what section of the book they are listening to without having to wait at their player. If a section header is found to be missing during the ACX QA review, you will be contacted to make revisions which could delay the release of your title. Be consistent - a listener may call back content is missing if most headers are read but some are non ."
Audio Specification
-
Each file must exist no longer than 120 minutes.
-
Each file must mensurate between -23dB and -18dB RMS.
-
Each file must have summit values no higher than -3dB.
-
Each file must take a noise floor no higher than -60dB RMS.
-
Each file must be 192kbps or college 44.1kHz MP3, Constant Bit Rate (CBR).
ACX explain how the file volition be encoded earlier being put on auction. "Earlier going on sale in the Audible store, titles are encoded in a diversity of formats that customers accept the option of downloading. 192kbps (or higher), Constant Flake Rate MP3 files are required so this encoding process works without error. You may upload 256kbps or 320kbps files if you'd like, just the difference in quality heard by listeners will be negligible."
Note that the ACX format uses RMS as a perceived loudness measurement as opposed to LUFS or LKFS. Audiobooks practise non use BS1770 loudness, they use RMS so make sure you tin can measure RMS. iZotope RX has this feature.
Don't Mix Channel Widths
ACX recommend mono files but will however accept stereo files, even so, you must not mix formats, the unabridged book must consist of all mono or all stereo. If you try and upload both mono and stereo your files will be rejected.
You Must Employ A Existent Person
You might call back we are joking but ACX requires a man to read the transcript, text to spoken language etc. is not allowed.
"Your submitted audiobook must be narrated by a human.
Text-to-speech recordings are not immune. Aural listeners choose audiobooks for the performance of the material, also as the story. To meet that expectation, your audiobook must be recorded past a human."
How Can I Be Sure I Get This Correct?
ACX has a handy audio analysis tool that checks each sound file as you upload it. If at that place are any problems it will tell you and ask yous to fix them and to resubmit the audio.
