ACX Audio Submission Requirements

The ACX website has the current instructions on Audio Submission Requirements, but here I'll type a summary of the main bits:

  • On ACX you can find and paid a professional voice narrator, or narrate it yourself (video).
  • You'll also need to include a retail audio sample that is between 1 and 5 minutes long.


  • Opening credits minimum requirements (must match book cover):
    • Start with: "{Title of audiobook}". "{Subtitle if applicable}". "Written by {Name of author}". "Narrated by {Name of narrator}".
  • Closing credits minimum requirements:
    • End with: "The end."
  • Split up your chapters into consistent files:
    • Start each section with: "Chapter 1: {Chapter title}."
    • Each file must contain only one chapter or section and be < 120 minutes.
    • Each file must have 0.5 to 1 second of room tone at its beginning and 1 to 5 seconds of room tone at its end.
    • Talk consistently (consistency in audio levels, tone, noise level, spacing, and pronunciation... free of extraneous sounds such as plosives, mic pops, mouse clicks, excessive mouth noise, and outtakes).
    • Mono files are strongly recommended (and must the be same for all).
    • Each file must measure between -23dB and -18dB RMS. Each file must have a noise floor no higher than -60dB RMS. Each file must be 192kbps or higher 44.1kHz MP3, Constant Bit Rate (CBR).
