I found the spreadsheets out there that has built in corrections for 1/3 octave or 1/6 octave measurements... But does anyone have a corrections list for ALL frequencies between about 15 and 100? I have the radio shack analog spl meter. I tried searching this forum and the search tool didn't seem to want to cooperate. I'm thinking about getting a BFD soon and got the snapbug worksheet and tones, but I would like to get an idea of my pre-equalized curve with 1hz resolution from about 15-100 or so. Thanks!
