I think the definition of "wastes" is very important here. Don't use space that is literally wasted, because it adds zero information. It's equivalent to a database which adds a sequence of 32 bits of 1's after every field. It adds nothing for any purpose, yet it uses space. This space is truly wasted. Same with storing audio we cannot possibly hear.
