From your description I hoped that you would be analyzing audio to solve problems that don't raise codes.
Years ago my daily driver had a noisy wheel hub bearing, so when I heard a similar noise in a different vehicle this year, I assumed it was the same problem. However, when a mechanic investigated, it turned out to be an issue with the breaks instead. I have now learned to discriminate between a bearing and a brake issue, but there are a ton of other conditions I've never heard before that would be obvious to an experienced repair technician.
I bet an app could become as good a seasoned mechanic at identifying mechanical issues from audio samples.
