Hypercardioid vs. short shotgun
Some short shotguns appear to have a pattern not dissimilar to a hyper. Are they interchangeable, especially inside?
My limited understanding is that a shotgun, even a short one, uses an interference tube, making it less directional at low frequencies, and inclined to "boom" inside. What are the relative merits of short shotguns and hypers? |

If you plot frequency response AND direction, you will see that a short shotgun is all over the place once you get off-axis. This means you really should aim it, otherwise the voice sounds weird and it will be difficult to EQ that off. With a hyper, you are more easily able to get away with things like aiming it in between two people (instead of at the person who is speaking at the moment).
2- The other difference is that shotguns sound weird indoors. My explanation would be that the reverb is being picked up weirdly due to the wild off-axis response. And there is the bass explanation. Regardless, they just do sound slightly weird indoors. If you are close with the mic, it mostly goes away. That's what I hear anyways.

Thanks, Glenn. That was my limited understanding. I have watched Ty's video, which is great.
So if short shotguns aren't so useful indoors, when would you use them? When would you use a short shotgun over a long shotgun outside? |

A- They're too much of a PITA since you really have to point em at the speaker. If the lines of dialogue overlap, then you can't do that (which you can say about the short shottie too, but it shouldn't be as bad). B- If you really have to use the mic indoors (with low ceilings and things like that), the length may be a problem. I believe short shotguns are typically used more than long shotguns in the field (except on soundstages, which is not in the field). Most of the time people use a short shotgun like the Sennheiser 416, or a hyper like the Schoeps. Some people just use a Schoeps for everything. |
