25 minutes, 4 channel surround and stereo
Stereo mix .mp3 [1mb]
This is a site-specific, "localization" performance test of the wide-spaced array. I started at center position 75 feet in front of the the array and moved in a counter-clockwise direction stopping in 18 positions to clap my hands.
As with many natural locations, sound paths change dramatically from position to position because of vegetation, obstacles like tree trunks and land/water forms. For example, sound from clap positions 2-6 seems to be reflecting from trees and bushes on the far right and reaching the right rear mic at a higher level than the direct sound reaching the left rear mic. Reflections from water come into play in the last clap position by directing more of the sound into the tree canopy.
No changes were made in the recording other than overall balance for left/right and front/rear. The rear channels are lowered -3dB in the stereo version with no changes made to phase.
