AziEzi
 
     
  AziEzi is a compact utility for adjusting azimuth of audiotape player's magnetic head. It integrates oscilloscope, Lissajous, level meters, treble booster, and signal generator altogether, enabling users to watch all the measurements simultaneously on a single display. Additionally, users can listen to the audio in stereo, mono, or L-R (left minus right) in real time.
