I've been doing a bit of recording work recently so I decided to compile a handy how-to guide for audio recording for elearning. The guide walks your through finding and setting up a recording space all the way through compressing the final audio files into MP3 format. Just follow the below link and click on the "Audio Recording for eLearning Guide" link.
Hope you find it useful. I'd love any additions or feedback on it for improvement so do share.
