I have a very long concert stream in AAC format totaling 105.9 MB. I'd like to do some editing, perhaps cut out the thirty-minute interview in the beginning and separate the songs into individual tracks. My first thought was to use Audacity, which I'm familiar with from having used it on windows. I downloaded the 1.2.3 version to my Rev D PB. However, Audacity won't import the AAC or mp3 version of the file. I searched for Audacity help, but none of the threads I found addressed this specific issue. In my searching, it seemed that some people were having luck using GarageBand, but so far it hasn't been so for me. When I drag the file from iTunes, only the first 90 seconds or so shows up in GarageBand. I'm not very familiar with GB, so I'm probably doing something wrong. Will Audacity or GB work for such a large file? Thanks in advance.
