London-based Pottermore Publishing, the digital publisher of the Wizarding World franchise, has partnered with Amazon’s Audible platform to co-produce new-and-improved versions of the Harry Potter audiobooks.

Audible’s complete HP audiobook collection will feature English versions of J.K. Rowling’s seven-novel saga, along with existing Pottermore co-productions Quidditch Through the Ages, The Tales of Beedle the Bard and Harry Potter: A History of Magic. The plan is to release each title globally in sequential order, starting with Harry Potter and the Philosopher’s Stone late next year. 

Audible CEO Bob Carrigan says the upgraded audiobooks will feature a voice cast of more than 100 performers, plus new Dolby Atmos technology to create a more immersive score and soundstage for the audience. The company is not planning to remove the original audiobooks, which have racked up more than 1.4 billion hours of engagement time on Audible’s platform since they were added in 2015. 

Penguin Random House started rolling out Harry Potter’s first audiobook series in 1999, two years after Harry Potter and the Philosopher’s Stone hit bookshelves at retail. Read by Stephen Fry in the UK and Jim Dale in the US, these initial editions were published as CDs and cassette tapes before making the switch to digital and launching on Apple’s iTunes service in 2005. Fry and Dale continued to work on the series, and audiobook number seven (Harry Potter and the Deathly Hallows) dropped in 2007.
