Beautiful Soundscape – Spectrogram Pro (with super-smooth 60Hz update) Review

This app makes use of the high resolution display to visualize microphone input. Remarkably sensitive. Try whistling! One of the simplest and most elegant apps I've tried so far. It always sparks discussion and interest, and makes you more aware of the aural environment around you.
