The Audio StereoScope is a Music Analyzer/Visualizer with a compact music player for the Java SE (Windows, Unix/Linux, Mac).

The Audio StereoScope emulates the Left & Right outputs of a stereo sound connected to the inputs of an Oscilloscope set to X vs Y (XY mode) - thus plotting the Left vs Right signal amplitudes in real-time.

It's truly a phenomenal method of visualizing stereo music.

To run program simply type:
java -jar AStereoScope_mp3.jar

The MP3 support is provided by the mp3spi, tritonus_share & jl1 JARs, the entire Java code was written in just over a week!

The next step is designing an Android version.
