Hello,

I make teaching videos on Youtube. I'm forever in the process of improving my audio. Right now I get pretty significant background noise (cars outside, wind noise against my apartment), using a Dynamic Microphone (Samson 2QU) on my desk, about 2-3ft 1.5ft from my face pointing right at me.

I'm looking for cheap / broad-stroke fixes to get better sound that could reduce all the extra corrections I am doing in post.

Currently I have a simple foam cover on my Microphone. I'm wondering if something more substantial would improve the audio I record. Namely, some sort of fur/deadcat filter:

I know their primary purpose is reduce wind noise. But I am recording indoors. Beyond that, do deadcat/fur filters provide any reduction in ambient noises?

Can they help limit the Cardioid pattern in any way to hopefully make it closer to (what I'm seeing described as) hyper-Cardioid?

edit: I'm actually 1.5ft from the mic, I just measured.
