How to Improve Audio Quality?

I was asked on how to improve audio quality. So I went ahead and did that.

1) Use Audacity: http://audacity.sourceforge.net/
Or an in-built audio changer
2) Increase the sound your microphone picks up
3) Use a pop-filter or sock to prevent background nice and to give a clearer voice.
4) Get a single microphone rather than a headset but DO NOT USE THE IN BUILT MICROPHONE ON YOUR DEVICE

Recommended microphone:
Blue Snowball: http://amzn.to/1FMnWdV
Blue Yeti: http://amzn.to/1Cu1eUc
RODE VideoMic: http://amzn.to/1zf9lmB
Sennheiser Wireless Transmitter: http://amzn.to/1MmAFZ9

These are all really good microphones. If you have any recommendations then leave it in the comment below. I am currently using the GX-05 Headset and you can find a review of that here:

I do a whole variety of videos but I specialise mainly in technology, gaming, science and maths so I will do them first. I am still trying to develop a team as well.
