Implement a simple Audio Vizualizer

[oseiasmribeiro]

Provide a simple Audio Visualizer (showing low, medium and high frequencies) that offers the possibility of increasing or decreasing a number of bars. This is useful for the user to make sure that the audio is being played or recorded in the application. Sometimes the volume or mic can be at a minimum.
