From the developer:
Sound View is an audio spectrum analyzer and spectrograph app. It analyzes sound from the built in microphone, or from the Line in input device, and displays the results in three separate views. The waveform view displays the raw input signal as a continuous wavy line, where each wave is a pulse of sound.
