What kind of mics can I "combine"
 

I need an analyser mic but I also need a regular studio vocals mic. In addition to that I also need a stereo setup for making videos with the DSLR camera.

I wonder whether I can do anything here to combine some if it instead of starting a collection.

An analyser mic does two things: it is omnidirectional [edited] and it is linear including the bottom, and it's bass response doesn't depend on the distance from the source. I think I could live without the omnidirectional aspect, it would be fine for me if I had to analyse by pointing at the speakers.

Any recommendations? Does anyone simply use a studio vocal mic or some directional mic for an analyser?

Every reference mic I've seen for RTAs or impulse measurements was an omni, not a uni (uni=directional). There are plenty of usable cheap ones, but there are also some medium price ones that work well for overheads or recording acoustic instruments. If you're on a tight budget I'd shoot for one of those.

They are Omni
The behringer rates very good. It will work as a good omni mic for other uses, like as a overhead drum mic.

$50 then you have all kinds of money left over for vocal mics ... that's the hard choice.

Woah, Behringer? :shudder:

On the other hand, I could stand the analyser mic to go out and not suffer too much. In fact I'm curious whether today's Behringer stuff is indeed less trashy than what I have.
