The horizontal axis represents time (in this implementation time is displayed in milliseconds) while the vertical axis represents frequency (in Hz). The magnitude of each frequency component is shown by the color.

WebFrom a practical perspective, the easiest way to do this would be to use an external program to play the sound, and invoke the external program from Mathematica. For example, on Windows, foobar2000 can be set up to display a nice spectrogram while playing, and indicate the current position within the visualization.
