I was listening to my alarm this morning from a lofi telephone. It's actually a step up from lo-fi so the sound quality is considerably improved, can't tell you the actual specs. The alarm itself is this chill, padlike song for like 10 seconds and then it repeats, like any alarm clock. So I was listening this morning and noticed that the piano part kind of blended in at certain parts with a pad in a very gentle way that made the piano's attack go away some and I was wondering if it was masking that I heard or just good mixing. So it got me wondering how useful masking really is, rather than something to just be avoided. Maybe I don't understand it well enough and maybe we can uncover some of the confusion and learn something new.
