I gotta be missing something very simple. When I delete a part of a recording (with only one track) in GarageBand and export it to iTunes, the length of the recording stays the same, so I end up with silent sections at the end. I am making some test recordings with Garageband, let's say about 10 seconds long. Then I delete the last 4 seconds of that recording through the "track editor", thinking that now I have a 6 second recording. Afterwards I click Share -> Send Song to iTunes. The recording stays about as long as what it would be without any deletion, so there is a 4 second silence at the end. I have also tried deleting the middle section and stitching the remaining parts together, the silent section is at the end again. Can anyboby tell me what I am missing?
