As recommended by an author client, this audiobook production agency would be worth considering for those thinking about trying an audio format for their book. The site’s blurb states that:
“Jacqui & Brenton Edgecombe are Australian audiobook narrators and recording professionals ready to create an ACX standard reading of your book for distribution via all audiobook platforms. We look forward to bringing your words and your story to life for those who prefer to enjoy their books audibly.
All work recorded in our Adelaide-based home studio. We use Rode Mics, Logic Pro recording softwater and Izotrope RX7 for audio analysis.”
