thanks for the advice, for the newest tutorials such as this one i am actually using a logitech microphone, but am aware of the background noise though.
What would be the best way to get rid of it, i'm not sure if a sound card would change anything, my computer certainly isn't noisy, only when rendering sometimes the fan speeds up as CPU usage increases, but not really during those tutorial recordings.
I'll also look into using Audacity and a High Pass filter, i happen to have the software on here but never thought of using it to remove the noise, are there any specific settings i should use?
One thing i was looking for was a small application which shows the actual buttons i press inside the video, i saw it once watching a video tutorial form 3d palace, but i haven't found anything like that unfortunately...
Thanks for the advice!
