I am preparing a tutorial for my new application using Lotus' ScreenCam.

I have done all the video recording and now have to add the voice track.

This is easily done (at least in theory) using the mic attached to the
sound card of my PC.

The problem is:

all sort of noises enter my room from down the street and in all the tests
I made the noise is well audible in the recorded track.

Still I have all my things here and would hate to migrate to a different
place.

Also I guess that if I don't rent a professional recording room - what
would be expensive and troublesome - I will find noise - more or less -
everywhere.

Is there a hw solution (a special mic ?) to filter out the noise when
recording and/or a sw solution (Goldwave ?) to filter out the noise from
the WAV file after the recording ?

Thank you
