Sorry if this is the wrong site to ask this question, with it not being strictly about video.
Say I’m conducting an interview in a hallway or similar environment. There are a lot of flat surfaces, maybe an uncarpeted floor, this is going to produce a lot of echo and sound distortion. A purpose-made room or studio isn’t an option as the interviews are supposed to be “of the moment”. How would I go about eliminating echo?
I can’t go around the whole location putting up blankets to dampen the echo, so would I be looking at some sort of attachment on the camera microphone, i.e. a windsock (or similar attachment if a windsock isn’t appropriate)?
