  Add xanalyser 1.29
  
  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.
