Now listen carefully. Tomorrow I am doing an interview with a scientologist for a shcool project. I am bringing my MacBook to record the inerview. Though it may not be more than 1 hour, I want to be sure my MacBook will have enough juice to record the entire interview, and since Garageband steals a lot of battery, I want a small sound recording app, which must meet the following requirements: 1. Low battery consumption 2. Universal 3. Support for MacBook internal microphone 4. Export to iTunes 5. Possibility for recording long audio files (perhaps up to 2 hours).
