Best Microphone Setup for YouTube

Hi. I'm pretty sure I'll be going with the lapel mic 👍

In addition to what Steve says, telling us your budget would help. Best mike for $100, or best under $2,000?

There's no such thing as 'best', and there are lots of different approaches - largely dependent upon your budget as much as anything. Software is generally mic-agnostic unless you are considering USB mics. If you are not proposing to use a USB mic then you'll need a suitable sound device as well. In general the results you get depend very heavily on rather more than just the mic you use - the local acoustics, background noise, how it's suspended, setup of pop and blast filters and a few other things as well.

If your dialogue is going to be in-vision, and you want it to pick up evenly if you move, then the solution is to use a lapel mic, the same as broadcasters. If you're going to be sat at a desk, then a desk-mounted mic will be okay, as long as it's suspended so as not to pick up noise from the desk itself if you touch it.

Bottom line is that if you want serious suggestions, that's fine - but you are going to have to fill in a few of the blanks!
