Yeah, I guess it wouldn't be optimal for ribbon mics, but for dynamic/condenser? Also, was thinking of an open roof type of stadium situation... or out in the desert on a calm and quiet night, where you have no ceiling? I dunno - have never done IR recording myself... just brainstorming possibilities to eliminate floor reflections, which I assume must cause some fairly substantial additive and subtractive interference in IR recordings.The problem with pointing it straight up is that it limits the mics you can use. Ribbon mics don't work well when oriented horizontally. The ribbon is designed to be vertical. Also, pointing straight up exaggerates the ceiling reflection.
