I'm leaving this afternoon for the UK (I'm in the US) for a series of business meetings Monday, Tuesday and half of Wednesday...the total meeting time is about 23 hours. I'm thinking about trying to audio record the meetings...I'm not the best note taker in the world. It occurred to me that there is probably some built-in software on my MBP that I could use...GarageBand? Is the built-in mic good enough to pick up the sound in a boardroom sized conference room with about 6 people sitting around and talking? Also, what kind of hard drive space can I expect the recordings to take up?
