Core Audio in watchOS 3

If you take a look at the differences document on watchOS 3, Apple has posted that Core Audio is now available in watchOS 3: "The Core Audio framework (

CoreAudio.framework

) provides data types that help you represent audio streams, complex buffers, and time values."

So can we use this to capture sample buffers as it is recording audio and if so, is there any sample code on how to do this?

Thanks!
