Audio Recording in Android Native Notes App

A

AC Question

Using the native Notes app on my Android version 4.4.2, HTC Sense version 5.5 phone, I recorded myself giving a speech. Now, I'd like to pull that audio recording off my phone. When I try to "Share" the note from within the app, it gives me an empty .png file, not an audio file. How can I access the audio recording itself? Thanks.
