Attention all Mac heads -- I've got what I hope is a simple question for you. Here's the situation: my 70-year old Dad has taken up songwriting in his retirement. Came out of the blue. Frustrated with the technicalities of making demo recordings in the PC world, he bought a new Mac G5 about a month ago when he heard about Garageband. The good news is that, with Garageband, he's finally getting some demos happening. He just couldn't get with it using a variety of different Windows-based software. Here's the question: using the stock software that ships with the G5, how can he make MP3 files 5MB or smaller? He's already asked his retailer and Apple themselves and he essentially doesn't understand what they're telling him, but he thinks they are saying it can't be done. We're talking a basic three to five minute tune here. I have almost zero familiarity with Mac stuff and I'm thinking one of my cyber-pals here on the board will know the answer pretty quickly. Thx in advance, you helpful bunch you.
