Null Testing and Listening Testing of “Mastered for iTunes”

In this video, Ian Shepard of Production Advice in the UK compares a CD track to both its “raw” AAC coded form and a “Mastered for iTunes” rendition. I think that most of you will jump to the punchline early on, but the journey is interesting (for audio geeks).

On a related note, I wish that the audiophile industry would do more null testing to answer simple questions like: “does this cable sound different from that one?” It’s really not that difficult.
