Can I use the old AVAudioPlayer with the new AVAudioEngine?

Question

My app plays audio files with AVAudioPlayer, and I've used most of its methods and properties to build a playback control interface with buttons to play/pause, seek, etc. Now I want to add a pitch-shift feature using the new AVAudioUnitTimePitch in iOS 8. I've found the sample code in this question and it works when I run it, but it uses AVAudioPlayerNode instead of AVAudioPlayer.

Is there any way to connect an AVAudioPlayer to an AVAudioEngine, instead of the AVAudioPlayerNode? Or is AVAudioPlayerNode completely different from AVAudioPlayer, despite their similar names?

I'm asking because if I have to replace AVAudioPlayer with AVAudioPlayerNode, I'll have to rework most of my control interface to use the different methods and properties available (or not available) in AVAudioPlayerNode.

I have been working with this for the past week or two. My goal was to create an AVAudioEngine player that mimics the functionality of AVAudioPlayer. It seems to work pretty well. Check it out and let me know if you find it of any help.

AVAudioPlayer and AVAudioEngine are different ways to work with audion on iOS. See following article for complete audio apis list with short descriptions: Audio APIs Owerview
