Side Vents on Mics
« on: Yesterday at 03:37:50 PM »
How important is it that the side vents on my AT853 cardioids not be covered?  I read in a thread about AT853 windscreens that the vents shouldn't be covered, hence my asking.  I typically record >:D and use these the croakie-like mic holders (see photo).  For concealment purposes, I usually pull the mics inside of the holders so that only the very tip is sticking out.  Have I been making a critical mistake by doing this?  If so, I'm going to have to come up with a way to allow them to extend out from the holders, while still keeping them concealed and also pointed straight forward.

Edited to notate my AT853s are cardioid mics.

The vents are a big part of what makes them directional mics.  At minimum you are modifying the pattern.

If they are pointed straight at the source, I don't see this inhibiting much of the sound?

Would love someone to chime in on this as well.
