I am on the market for a voice recorder for recording class lectures. I sit in the 3rd row less than 10 yards from the professor and he speaks at a fairly normal lecture volume. The room seats about 40-60 students I believe, so if you have any recommendations on what brands or models would work for my situation that would be great. I need it to be compatible with a MacBook Pro (Intel chip), and I thought the USB connectable ones would show up as a flash drive but apparently some are not compatible. My price range is basically under $50. Under $40 is preferable but if its not going to happen then $50 is fine. So any help and recommendations are very appreciated.
