How Long Does It Take to Find the Tempo of a Song?

Vincent lepas, the third sayd i made him sound a little spanish. That's what we do here we anything french, forget about it. He asked about gain staging and how to find a sweet spot an a given piece of gear or a plug in asks about which processes are better than others for gaining or trimming. And then he also asks, what processes, if any, respond better to lower levels? Great stuff to think about here.
