Sound You Can See !

Sound View is an Audio Spectrum Analyzer App. It analyzes sound from the built in microphone or from an attached external microphone and displays both the input signal and the results of the spectrum analysis. The input signal is displayed in the lower view as a waveform and the spectrum is displayed in the upper view as bars indicating the strength of that frequency within the input signal.

Frequencies range from 0 hertz to 22000 Hertz or 22K this is the range of the microphone and also the general range of human hearing.

You can double tap either the spectrum bars or input waveform to display only that view full-screen. Another double tap will return the display to showing both spectrum and waveform. Both portrait and landscape mode are supported.

Tap the levels icon to display the window controls. There you can control the horizontal and vertical scale of both the waveform and spectrum views.

On the spectrum view you can also use a slide gesture to move the display left and right allowing you to see specific frequencies in detail.
