I don't care about audio destuttering, but there will come a time when my apps will be made better by a finicky feature that requires similar expertise. Rather than dreading the process (as I do now), I want to learn how to efficiently source this kind of domain knowledge and then implement it without too much of a hassle. Deep, needle-precision learning. Most programmers don't have books written about their work, but I think most great programmers (of the kind I admire) could write an in-depth book about the unique things that they've written and discovered.
