I can’t upload anything in the mic section. How do you upload a file when it doesn’t let you? I click on it and it just exits out of the mic screen. Please fix.

Bought this to measure a high-frequency hum which disappeared when I bought the app. So thanks for that. Seriously, though, a very nice UI wrapper around the FFT.
