How do you make sounds?

[Darker]

I was always bad with graphics, however, I can at least approximate what I want using pencil and paper.
However, though my head is full of sounds I'd like to add to my mods, I have no idea how does one turn these ideas to reality.

I could think of games that contain similar sounds... that's all.

So, is there anyone who knows how to make new sound? Ideally somebody willing to co-operate with me?

A microphone and decent sound editing software. Last I used was Audacity, and it's free.

Otherwise, browse around a free sounds archive. There's a few on the 'net.

Sometimes, I was successful with searching, but I was never fully satisfied.

I tried downloading audacity, but I have no idea what should I do with those wawes... I didn't even succeed to edit the downloaded sound...
