Am I understanding RC filters correctly?

I’m a hobbyist with almost no background in electronics, but I absorb some info from reading stuff on the forum. I wanted to see if I understood this capacitor change correctly.

I have a raincoat. C6 is 10nf. I didn’t have one, but I did have a 12nf, so I used it.

Does this create a high-pass filter with R11? Is the stock cutoff about 159Hz, and my substitution is 132Hz?

From the placement of that capacitor, it looks like it's purpose is to block DC from going to the next gain stage. A 12nf will work fine there.
