When to use audio instead of text
The recording part is pretty easy and as long as you have a decent sound card in your computer the incremental cost is quite low. That stick mic is from Koss and costs less than $20. The software is Audacity which is open source and hence free. (You need the file lame_enc.dll on your computer for Audacity to convert your recording to MP3. That file is also free.)
The harder part is thinking through when audio really is better than text. Here are some suggestions.
