Nikon ME1 Stereo Microphone
do you have any other sugestions. It needs to be clean sound.

No. That Nikon ME1 Stereo Microphone is for Nikon DSLR cameras, not for computers. Get the Blue Microphones Yeti, it is excellent and would be perfect for your purpose. Records great sounds with lots of clarity and has a very good frequency rate. These microphones are designed for computers and are plugged in the USB port and ready to use. Just buy along with it, the Tiger Pop Screen with Large Pop Filter. You can see the mic as well as the Pop filter at the links below:

NB: The pop filter is not a compulsory equipment to get, but is surely a huge plus for quality recording as it helps to refine the sounds that goes in to your microphone

If recording straight onto your computer you should probably get a USB microphone, such as this;
