Neat! I translated my code to Rust line-for-line and the iterator approach significantly outperforms it.
Rust newbie q - why use `x.wrapping_sub()` instead of regular old `x - 1`? Seems like we're never going to underflow `usize` for any of the 3 formulae?
This article is a specific case of a more general piece of advice: ask questions well (provide context like clickable links, trim down your query to the minimal reproducible case, pose high-precision questions, etc.).
In addition to the feature being auto-on (for me, at least) and unasked-for, you also need to perform multiple clicks through non-obvious menus (I think one of them was "Audio track"?) to get to the original audio. Another layer of obnoxiousness.
