I want to change audio's playing speed (such as *1 *2 Fast ,or 1/2 1/4 slow motion) in my Windows Phone 8 App. By testing in my IDE and reading the former related threads , I 've learnt that WP8 SDK does not support PlaybackRate property. My question is that in the latest version of PlayerFramework , is it supported ?
Although this framework is based on MediaElement by WP8 SDK, the framework may simulate this function as so many developers really need it.
Thank you~
