        Nice prose, but I'm dubious about how he's interpreting "iteratively". AIUI, there's some overlapping compression in MP3, but not recursion.

        Yeah interesting point, I don't know the technical specifics. I think he might mean that you can continue to prune parts of the audio that human hearing is not optimized for? The rest of the chapter focuses on the creators tuning this aspect for different kinds of music and audio

    Loading seems to be taking a while.
