MORE ABOUT THE MASTERING PROCESS:
The mastering process will allow your audiobook to “sit” correctly in your headphones. Levels will not fluctuate and frequencies are adjusted so that the sound of your audiobook is crisp and clear on any device. Low frequencies are cut to avoid rumble and extreme highs are adjusted to acceptable levels.
Mastering raises the level of the end-users listening experience. Listeners will not have to adjust their volume and can concentrate on what really matters - the author’s words and the narrator’s voice. Audiobooks accompany people in all different settings and a well-executed audiobook production will give your product more flexibility in the market.
Many audiobooks today follow the guidelines of the Amazon-owned Audio Creation Exchange or ACX. ACX is platform where narrators, publishers, writers and editors can connect. ACX requires that all submissions adhere to their guidelines. The mastering process is the part of the procedure where all these requirements are met.
Files are numbered and named correctly. Sound is treated to ensure a consistent overall level. Overall levels must measure between -23dB and -18db RMS and have -3dB Peak values and maximum -60 dB noise floor. The final file format is 192kbps or higher MP3, Constant Bit Rate (CBR) at 44.1 kHz
