A friend airdropped some long mp3s to my ipad. The only app I had at the time that would play them was iMovie, so I checked them with that. However, I now want to extract the audio files and transfer them to a pc, so I can publish them to a website. Where are they and how do I do this? It cannot be done within iMovie (for ipad), seemingly... The files show up fine as clips within an iMovie "project", but there seems to be no way of extracting them, even into iTunes.
