Tim,

Audio recording via script is fairly straightforward. See my tutorial here for the basics:

http://livecode.byu.edu/audio/audioIntro.php

Just scroll down to the section on Recording Audio Files.

This tutorial doesn't cover everything about recording in LiveCode, but if you type "record" into the filter field of the dictionary you'll see most of what you need.

The tricky-ish part will be automating the process, but 'send in time' should get you most of the way there.
