How do I upload my first chapter of audio to be proofed?

Looking to upload your first chapter of narrated audio into our proofing tool? It's easy to get started!

How to Upload Your First Chapter

Once you’ve created your first project, the next step is to upload your chapter audio.

Please keep the following things in mind:

  • Pozotron does best when you have one chapter recorded per audio file.
  • Pozotron accepts audio files in .mp3, .wav, and .flac formats
  • The maximum length for a file is 120 minutes - you’ll have to split your file up if it’s longer than this.

To get started, open your project to get inside. From there, you can either drag and drop your audio files on the region shown or click on the “Drag and Drop” message to open a file picker window.

Good to know: Pozotron can detect and match your script to your audio files regardless of the naming convention.

Upload One or Many Files at a Time

You can upload one file at a time, or a group of however many you'd like. You also don't have to upload chapters in the order they're in your book; we have options to reorder files via your main project view.

Files start processing right after you add them to your project. Go grab a cup of tea or coffee and come back, and you’ll be ready to roll.

Users have very different workflows when it comes to using Pozotron, but you can see the basics of how to proof in Pozotron to get started.
