This investigation employs a simple graphical method in an effort to represent the perceived spatial attributes of three microphone arrays designed to create vertical and three-dimensional audio images. Three separate arrays were investigated in this study: 1. Coincident, 2. M/S-XYZ, and 3. Non-coincident. Instruments of the orchestral string, woodwind, and brass sections were recorded. Test subjects were asked to represent the spatial attributes of the perceived audio image on a horizontal/vertical grid via a pencil drawing. It can be seen in the subjects’ representations that these techniques clearly capture much more information than a single microphone and exhibit vertical as well as horizontal aspects of the audio image.
