Amazon is integrating its Audible audiobook service directly in to its Kindle mobile apps for both iOS and Android.
After installing the update, which is rolling out today, Kindle app users will be able to listen to Audible audio books without ever having to leave the app.
The service is an extension of the Whispersync for Voice feature that allowed users to switch between reading and listening but required users to have both the Kindle and Audible apps installed.
With the updated Kindle apps, users will be able to get narrations for 45,000 Kindle books as well as purchase Audible upgrades for previously purchased Amazon Kindle books ranging from $1 to $4.
The audio and text versions of the book will stay in-sync, pages turn automatically, and narration includes a x2 speed mode and sleep timer option.
The update includes other new features too, including: improvements to the X-Ray reference tool for textbooks and the ability to download an entire collection with a single tap.
The seamless Audible integration feature remains the predominant function of the update and will most likely be the one users appreciate most.
