This tool lets you take a closer look at the noises and sounds around you. Take a look at the frequency make-up, the sound pressure levels and the measured waveforms. (Results may vary with the different microphones and their settings on various phone models.) For Mango and upwards. v2.0. -Pitch detection fixed. It was off by double apparently. -Added fundamental frequency display on FFT (Tick + Number). -FFT expanded from 512 points to 1024 points. -FFT now only updates when in view, to save battery. -Removed zoom from FFT. Seemed useless and clumsy, since it ended up in a blurry mess. -Logarhithmic mode on FFT. -Frequency graph mode added, linear and logarithmic display. -Moved a bunch of options into the roll-up menu. -Put app options onto their separate page. -Removed internal memory manager, unnecessary thanks to Mango's generational GC. Also removes a source of obscure crashes. -Works best with Mango's default Dark-Red theme. v1.7: - Backported a bunch of internal optimizations done in the WP7.1 build. - Options background fixed.
