Audio Analyzer
Considering a cell phone is the LAST device you would want as a true and accurate analyzer, I am impressed with this application! Being a practicing Audio and Recording Engineer, having a hip-mounted "quick and dirty" tool like this is a great help! THANKS to the author of this handy little tool! A.Woodard Charlotte, NC
