About Conver Audio app

It seems to me that this app missed something very essential. The main function is to convert audio but when I tapped the load media box, it popped up all photo options (photo library,camera roll, camera), not related to audio at all. How can I find audio files to be converted from those photo sources? Next, when I tapped the load other box, it gave the information about using the open in option. I, too, didnt see any open in option appearing at all. If it really missed something, please review the issue and send me an update. Thanks. William Lee
