Hi! First of all thanks for creating such an App. It is helpful for academia work. One thing what would make it even better is to add Sound Recording Function into it, like in Evernote. It would be great to use it extensively in Lectures and Presentations.

The PDF Annotations Pack (available through in-app purchase) includes an audio recorder, to embed audio notes to your PDFs. Is that what you are looking for?
