Add documentation/blog post comparing different types of mics

[harsh183]

So far I've tried different type of microphones and we can document this somewhere for people. Here have been my experiences so far:

Lapel Mic

Pros:

• Picks up the professor's voice pretty well
• Small form factor
  Cons:
• The professor often has to wear multiple mics now.
• Requires the professor to do some work too.
• The professor has to make sure the mic is on.
• Has a usb connector dongle (instead of using something like bluetooth)
• Slightly fragile

Laptop Mic

Pros:

• Doesn't cost anything.
• No setup
• Picks up both professor as well students around.
  Cons:
• Bad sound quality (-> meh captions)

Ommidirectional mic

(I tried one lecture with Colin's mic, not sure what model it is but it's in reference to that)

Pros:

• Picked up a lot of the professor talking
• Picked up a good amount of other students
• Bluetooth wireless so I can sit anywhere
  Cons:
• Not as good as lapel mic on professor
• Huge form factor, doesn't even fit in my bag so I have to carry it briefcase style
• Takes 5-10 minutes to set up before lecture start
• Sometimes unsure if connected correctly. Colin recommended putting it on mute to check and it worked but I had to go back and forth a lot.
• Expensive
