Looking at your “Everything you need to know about digital audio files,” I know that AIFF is uncompressed. I am still converting my CD collection to ALAC. I am about halfway through, so before I go start my many Prince CDs, I skipped about and did my five U2 albums. I found the “One” CD single, which has about 4 songs. Instead of ripping it, I just decided to keep it as is and copied the songs straight from the CD in AIFF format. I did this because in total the songs only came to about 325 MB in AIFF, and unless they re-release it, I won’t buy it again. Did I end up with the same file as if I ripped it into AIFF?
