Creating and publishing an audiobook on the ACX platform involves several steps, with the proper export and upload of your audio files being crucial. Ensuring your files meet ACX’s specifications will help avoid delays and ensure a smooth publishing process.

Preparing Your Audio Files for Export

Before exporting, make sure your recordings are of high quality. ACX recommends a sample rate of 44.1 kHz and a bit depth of 16-bit. Your files should be free of background noise, clicks, or pops. Use audio editing software like Audacity or Adobe Audition to clean up your recordings.

Exporting Your Audio Files

Follow these steps to export your files correctly:

  • Open your project in your audio editing software.
  • Ensure your tracks are properly balanced and edited.
  • Go to the export or save as option.
  • Select WAV or AIFF format, as ACX prefers these for upload.
  • Set the sample rate to 44.1 kHz and bit depth to 16-bit.
  • Name your files clearly, using consistent naming conventions.
  • Save the files in a dedicated folder for easy access.

Uploading Your Files to ACX

Once your files are exported, you can upload them to ACX:

  • Log in to your ACX account and navigate to your project dashboard.
  • Select the option to upload audio files.
  • Click ‘Choose Files’ and select your exported audio files from your folder.
  • Ensure each file is correctly labeled and matches your manuscript chapters.
  • Follow the platform prompts to complete the upload process.

After uploading, ACX will process your files. Make sure to review the audio quality and chapter markers before submitting your project for approval. Proper export and upload practices will help ensure your audiobook is published smoothly and professionally.
