Good start Basic functionality good. I'd really like a save option for a csv file with the data in it as well as image. I also occasionally get an 'error opening audio' problem on Galaxy s5. Small nerd point-fft can only be done on power of 2 length samples yet you can set the value to anything. Are you padding the input data with zeros? Might be best to stick to 256, 512, 1024 etc.?Happy paid for app, price fair for functionality.

Met all requirements I use the app to characterize the audio environment and sound systems in various locations such as classrooms, stadiums, and theaters. While nothing is precisely calibrated, it does provide a quick check of frequency response across the audio band.
