Permission to Record?

Second class today and we worked on gathering field recording. This essentially meant, go and interview strangers, record it and return to class. We had about an hour and our group ended up with 8-10 interviews. Then we imported the MP3s into Final Cut Pro to manipulate the audio into an audio track. I have done the same thing in Garageband (and  Audacity) and rather record my interviews directly onto my MAC and edit in Garageband; just like my Classical Tibetan Class. We have to have an audio file for class next Wednesday and my professors do not mind if we use another program or equipment to achieve our assignment. The reason for the lesson was to provide one solution to the problem.
