Getting the audio file from the document directory - ios

Question

I have looked through the whole internet to find a way to obtain the whole recorded audio file from the document directory. Is there any way to do so? Do you normally do it via an AVAsset/WKAudioFileAsset?
I tried to print the Asset and I got something like this here:
Are these the .wav files??
I need the recorded .wav files to send them to the server.
I hope someone can help me out. Thank you very much.
Here is the whole code: http://s000.tinyupload.com/?file_id=38128676605242153939
