My wife is going to be giving a series of classes that we'd like to record so they can later be sold on CD or in MP3 format. The classes will take place in a room about 40x15 feet. I don't have any experience with this type of recording, and I'm wondering what a good set-up might be in terms of gear. I have an Audio Technica ATR3350 that I use with my Kodak Zi8 video camera. I also have an iPhone 3Gs (soon to be iPhone 4), and an early 2010 MacBook. Is there a way of using any of this equipment to produce a fairly high quality recording? If not, what should I buy? Also, which iPhone app would be best for recording in this type of situation?
