Morning Nathan!
A little late to the game, but you might also want to take a look at an app that my friend and I just release (8/4/2011). It is called 'Teacher Notes' and is extremely handy for what you are looking to do. It will absolutely allow you to do the core functionality that you are looking for (audio recording and filing) but will allow you to do a lot more as well.
Below is the detailed description of the app, but in general, it will allow you to very easily take and file notes by domain, subject area and child over multiple classes. If you do take the time to download and browse the app, we would really value your feedback. Feel free to reach out at anytime @teachernotes on twitter!
Teacher Notes is a program designed for teachers note taking needs. It
functions as an easy way to file written notes, photos, movies or
audio on multiple children, domains and content areas all at one time.
Then when it’s time to write reports cards or evaluations Teachers
Notes has a quick way to sort notes by any combination of children,
domain and content area. You can then e-mail your notes to your self,
or email just one note with its accompanied photo, movie or audio
file. You’ll find that teacher notes functions much more rapidly than
jotting down notes on a clipboard and you’ll be able to find your
notes much faster than looking in a notebook.
