I found an interesting quad scope article. The circuit looks easy to make. You should use 1% tolerance resistors.

I built something like that.

But you can tell with an ordinary oscilloscope connected in X-Y mode to the stereo channels (connect left to vertical).

- Left channel info shows as a vertical motion.
- Right channel info shows as a horizontal motion.
- Items panned to center (front) in stereo, RM, or SQ appear as a 45 degree diagonal with the top at the right of the scope.
- Material in the back channels of RM, QS, EV, and Dolby Surround shows up as diagonals with the top at the left.
- SQ back channels, and UMX center front and center back show up as circular motions.
- Multiple sounds show up as a scrambled wiggly area. Stereo shows up with the wiggly area as an ellipse with the long axis diagonal with the top at the right.
- Surround shows up as a circular wiggly area.

I found a free oscilloscope program that works on your computer with your sound card.

Good find
Now does anyone know how to open this with a Mac ?
Thank you

I found a free oscilloscope program that works on your computer with your sound card.

Appears to be stereo however, the quad scopes handle four input signals.
