Good idea; but needs work

Got the app at a Metallica concert last night to see how loud the show was; unfortunately app tops out at 106 dB not reported 110. Here in my quiet office, the peak is jumping all the round while my SPL meter indicates fewer and lower peaks. App seems to be reporting higher average dBs than meter (3-4 dBs). App says snapping my fingers is 100 dB while meter says 50. Algorithm seems to need some slight modification. Often, I get the Peak Hold not refreshing and the Peak" to freeze as well. The Sample Rate slider is rather hard to grab and does not move smoothly. Previous reviewer suggested different meter skins; great idea (analog, digital, equalizer, numerical, etc.). I would be happy to help test future versions if you need it.
