Not to hijack this topic, or dispute any of the above, but I have always wondered why, from a technical perspective, folks often recommend omnis outdoors.
Am I correct that the technical explanation goes something like:
Outdoors, you don't have a "room", so room reflections that often make omnis undesirable from any significant distance indoors are not a problem.
Omnis are less sensitive to wind.
Is there anything else? Because I would still think that since an omni is picking up 360 degrees of information, it would still be undesirable at any distance because it would sound more distant relative to a cardiod.
Assuming wind can be eliminated as an issue (i.e., by using proper windscreens), wouldn't using a more directional mic like a cardiod still be more desirable (again, at any significant distance from the source)? I get why hypers are probably not ideal outdoors...
