+XAnalyser is a program to analyse a stereo audio signal. It has two 
+displays:
+Frequency Spectrum
+
+Using Fast Fourier Transform, the time domain of the signal is 
+transformed into the frequency domain, i.e. the amplitude (in 
+logarithmic scale) of the audio signal is plotted versus the 
+frequency. Either the sum of the left and right channel of the 
+audio signal can be shown or both channels simultaneously.
+
+XY Scope
+
+Roughly speaking, the audio signal of left channel deflects a 
+point horizontally and the right channel vertically (just as the 
+beam of a CRT would do). Thus, an audio signal only present on 
+the left channel produces a horizontal line, whereas an audio 
+signal only present on the right channel produces a vertical
+line. A mono signal produces a 45 degree line. A stereo signal 
+creates a wilde pattern (if the phase is correct, predominately 
+in the same direction as a mono signal) or may even fill the entire 
+scope.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
