Creating an audiobook for ACX (Audiobook Creation Exchange) requires careful preparation of your audio files to ensure they meet all the platform’s standards. Properly formatted files facilitate a smooth review process and help you get your audiobook published faster. This checklist covers all essential steps to prepare your audio files for ACX submission.
1. Record High-Quality Audio
Start with clear, professional recordings. Use a quality microphone and a quiet environment to minimize background noise. Record in a consistent tone and pace throughout the book to ensure uniformity.
2. Edit and Master Your Audio Files
Remove any mistakes, long pauses, or background sounds. Use audio editing software to normalize volume levels and add equalization for clarity. Aim for a consistent sound quality across all files.
3. Maintain Technical Specifications
- Sample Rate: 44,100 Hz
- Bit Depth: 16-bit
- File Format: MP3
- Bit Rate: 192 kbps or higher
4. Split Files Correctly
Divide your audiobook into individual chapters or sections, naming each file clearly and sequentially (e.g., Chapter01.mp3). Ensure each file is within the maximum length of 120 minutes, if possible.
5. Check for Audible Submission Requirements
Review ACX’s specific guidelines, including:
- File naming conventions
- Intro and outro requirements
- Metadata consistency
- Cover art specifications
6. Prepare Cover Art
Create a cover image that meets ACX standards: at least 2400 x 2400 pixels, in JPEG or PNG format, with a 16:9 aspect ratio. The cover must be clear and visually appealing.
7. Final Quality Check
Listen to each file from start to finish to catch any errors or inconsistencies. Confirm that all files are correctly named, formatted, and free of technical issues.
8. Upload and Submit
Upload your files to the ACX platform, fill out all required metadata, and review your submission carefully. Once everything is verified, submit your audiobook for review.
Following this checklist will help ensure your audiobook files are ready for ACX submission, increasing your chances of a smooth approval process and successful publication.
