Audible's iOS Platform Team

For the first time in their history, the Audible iOS team debuted at an external iOS Meetup. The team was in full force, sharing some of the powerful technologies behind several core elements of Audible’s apps. Audible’s playback engine and Whispersync were the order of the day.   Audible’s playback engine is a custom AVAudioEngine pipeline that allows us to convert and transform audio, providing our users with an unparalleled audio experience. Audio begins in our proprietary audio format, subsequently converted to PCM, piped through a mixer unit, then ultimately to your ears.

Readers can switch seamlessly between reading and listening without losing their place

Ronak's Presentation

Introduced in 2012, Whispersync for Voice is an Audible innovation utilizing Amazon’s eBook to audiobook synchronization platform, enabling readers to switch seamlessly between reading and listening without losing their place. iOS participates in this ecosystem by exchanging book position information at certain key points, ensuring our users always have a great experience.  

See our presentation deck (http://stackuptalks.com/s/Audible-Meetup-Talk-Slides.pdf) for more information.   Happy listening, and we hope to see you at our next Meetup appearance in the very near future!
