Slapback

Slapback is what audio people call a single, sharp echo — one clean bounce, right behind the original. Fitting name for this blog: short pieces, one bounce deep, on the corners of call echo the big guides don't cover. The odd questions, the "wait, why does it do that" mechanics, and the occasional honest look at what a tool actually claims versus what people assume it does.

The reference material lives in the software guide and the diagnostic pages; Slapback is everything that didn't fit — updated when there's something worth saying, not on a content calendar.
