Chapter 6 The Extended Audio Matrix. PRELIMINARY Release MSD Software Manual.

7.2.1 The Audio Vector Oscilloscope

The ‘Audio Vector Oscilloscope’ is also known under the names ‘Stereo Image

Monitor’ or ‘Goniometer’. It is based on continuous graphic illustration of a

stereo signal in the Lissajous-format.

If phase and amplitude is randomly distributed, the signal is an ideal stereo

signal. Normally this will only happen with a live recorded signal. Applause from

a live-recorded audience is an excellent example of a true stereo signal. The

figure of a true stereo signal should be represented on the ‘Audio Vector

Oscilloscope’ as a perfect circle, or rather a ‘ball’ See the illustrations below on

examples of different signal types as they appear on the ‘Audio Vector

Oscilloscope’, and note the relationship between the representations on the

‘Phase Correlation Meter’ and the ‘Audio Vector Oscilloscope’.

Ideal stereo signal. Reversed phase stereo signal.

Left signal. Right signal.

Mono signal. Reversed phase mono signal.

Please refer to section 5 ‘The Compact Audio Matrix’ on how to select the two

source signals for the ‘Audio Vector Oscilloscope’. Destination #53 and #54.
